If people don't like precision they can go somewhere else to get their woodworking content. Keep doing you William, there are plenty of us that appreciate it.

William, I go to the college of KZfaq for woodworking, and you are my favorite professor. I have learned a ton from you. Keep on posting.

I am an engineer (also retired as another poster mentioned) and I appreciate your focus on precision and using math where appropriate. Never apologize for that. Those who don’t care about precision or who didn’t pay attention in high school trig class can go elsewhere as there are a lot of “close enough” videos on youtube for folks like that. You appeal to folks who want to be the best they can be. Ignore the folks who are in the “mediocre is good enough” camp as they have many other youtube contributors they can watch.

William, do not ever apologize for wanting to make us better woodworkers. There is only one word to describe the haters.....jealous!

Haters gonna hate but at least 88,000 of us like the way you do things and learn from it. Thank you.

Don’t make it simple for the trolls. Your level of knowledge is more like the wood whisperer and not Steve Ramsey. I watch both of those guys for very different reasons. Teach what you want at the level you want. Your 5 cut explaination was the only time I understood that method. My jig is less than .0001 off and I love it.

William, please ignore all idiots, all you are doing is trying to help people and that to me is being a gentleman and I truely thankyou for all your posts and the time you put in to share your valuable experiance with the lesser wood workers amongst us from Garry in the UK

I watched your 5 cut video. Finally, here is someone who knows what he is doing. Never apologize for doing something right. It all made perfect sense to me. Too many folks get on KZfaq and it is obvious from the start they don’t know which way is up. Thanks for doing it right!

Beautiful gentle delivery from whom I imagine to be a really nice guy. Simple to understand. Perfect. Thank you.

Please, please, please don't stop making videos. They're an invaluable resource for those who wish to learn.

This modern world has many ' not so nice ' people living in it . They are given over to self indulgence and immediate gratification . I hope you disregard these people. Your videos are superb visual insights into how a master craftsman applies logic and reasoning to the various problems which we woodworkers all face . Keep up the great work .

Don't EVER let people with negative attitudes stop you from doing what you are passionate about. You a master craftsman, and the only reason why they make negative comments is because they are envious of your ability and passion. If they were true artists, they would add to the community, not subtract from it. We are all learning an immense amount from you, and are very appreciative of everything you are doing and giving. Thank you so much!

Viewing this almost exactly 3 years after it was made. This 2-cut method for the miter sled, and the 5-cut method for the cross-cut sled is so well explained and so straightforward, who wouldn't want to put this little extra effort in to make perfect 90s and 45s?

Great video, I love the math explanations for your projects. The haters are probably the ones who didn't pay attention during math class in high school.

William keep doing what you do. Don't waste your time on those haters-we love you the way you are.I think I learned more from your videos, then, in my wood class in HS. Keep up the great work

Thanks for the heads up about haters! I didn't quite understand the 5 cut method the first time I watched, but I watched it again and it makes total sense now! Don't give the boneheads any credence. Love this crosscut miter sled, I will definitely be adding this to my sled when I make it! Thanks!

You're a woodworking genius. Don't let the negative life haters stop you. Lot's more people get great benefit from you, and others that share their knowledge.

Absolutely CONTINUE to be as informative and detailed as you have been with your videos. I wish more content providers were this professional with their content, but not everyone works to the same standard and we all can accept that. For those that want "fun" without understanding function can watch someone else. Thank you for all you provide!

This video and Mr. Ng’s video on the five cut method are the two finest woodworking tutorials you will find on KZfaq.

It's amazing that people get mad at others because of their own failings. You are doing a GREAT job, William, don't let anyone ever tell you any different. Those of us who appreciate precision enjoy your tutelage. Those that don't, you should just ignore.

Glad to see you back on KZfaq William. Ignore the morons and keep posting excellent content. I'm always grateful to have a had you as a teacher.

I make frames for my paintings and have trouble getting corner cuts precise. I watched your video a couple of times and went to the basement to build one. When both sides of my little triangle measured identical to the one-thousandth, I thought I must have measured the same side twice. Nope, it was perfect, first try. Thank you for excellent instruction. Oh, and I appreciate the math.

William, do not listen to or believe that precision woodworking is not needed or appreciated. Your method and videos are excellent sources of needed information. I am a Tinsmith who first passion is woodworking. Thank you for increasing the precision and sharing your process with woodworkers like me who enjoy reaching for 100 percent. Wood has an unpredictable variable than happens in a project. So, when i reach for 100 and get 95%, I'm not discourage, I am motivated to reach that 100%. Most Craftsmen of Journeymen I know always reach for perfection knowing it is not always possible. Thank you for reaching for high quality workmanship.

I agree. Not everyone needs to be so precise, but when you do, it is nice to know there is someone like you teaching us how. Thank you for showing us your techniques. I think math teachers would be smart to show your videos to students who don’t think they will ever have a use for the formulas they are learning. You may spark their interest.

I have so much respect for this man, he seeks perfection and is a great instructor. Thanks so much for posting!

Master Ng, You are my go-to woodworking professor. My one comment concerns the wood runners; no matter what wood I use, invariable they swell or shrink...-stuck in the morning, loose in the afternoon. I have forever forsaken wood runners. The store-bought UHMW runners are expensive ($30 a pair!)...my local Plastics company sells cut offs from their scape bin by the pound. One scape piece of UHMW resulted in 4 pair of runners...I paid$1.89...just wanted to share with my woodworking brothers and sisters out there! Thank you for the best professional, insightful and educational woodworking videos on KZfaq!

I've been a woodworker for over 50yrs and this is the easiest and less complicated way of making a miter slide I have ever seen. Thanks. Plus who said an old dog couldn't learn something new and this is why I'm here.

Your "five cuts" is the first video I watched from your experience. It was an excellent tutorial on sled making. Thx. Social media will always have it detractors. "Dust your feet" and keep walking! You have much to share and like most of us tuning in, we appreciate your lectures.😎

Haters are just jealous. what you are doing is invaluable. You might ask what they are doing to help others. Obviously these are people with small minds! keep doing what you do. I have been in woodworking for over 40 years and I'm still learning everyday.

You're correct. Haters gonna hate. Don't ever let them get to you. Be true to yourself. For all true craftspersons, your videos are truly instructive. Professionally presented and produced, with wonderful content. Thank you for sharing your perfect table saw sled methods. They remove all the guesswork, allowing anyone to dial-in a table saw in a very straightforward manner.

I have always loved every video you put out. William don't listen to those trolls. I once edited an video from a young woodworker and tried to warn him of grave errors he was making. One so serious he was lifting a piece of plywood while the table saw was running. No riving knife was attached. I warned him of the danger he was creating. I had several trolls tell me I was wrong to correct him.

Recently I discovered your tutorials , your delivery is excellent , your sense of humor clean , and the knowledge of experience impossible to assign a price to . Sadly there are people so uncouth , so ignorant , so arrogant and self absorbed who make it a mission to show the rest of humanity the ugly side and mean spirited nature of their character , as they have with you William . But as others have stated , there many more of us who enjoy learning from you than exist of those who have behaved so appallingly towards you . Thank you for sharing with us , you valuable knowledge and experience.

Hi William, I am new to the channel but this is exactly the kind of content I want to find as I am an experienced woodworker just wanting to learn more. Anyone who can't or doesn't want to back up their methods with math/science isn't the kind of person I want to take advice from. KZfaq is littered with newbie videos and guys/gals with shops full of sponsored gear but who don't know what they're doing. Your channel is for serious carpenters and woodworkers and I'm glad for it. Cheers.

I just watched the 5 cuts sled video and immediately subscribed to make it easier to watch all of William's videos. My only regret is not having William as a teacher when I was in school.

William, I know this is a Old video, but anyone attacks you are only ingorant. I enjoy Your videos and You William are a very patience Craftsman and for that I THANK YOU. Your Videos is a Wealth of KNOWLEDGE THAT ANYONE WITH A BRAIN WOULD TREASURE THAT KNOWLEDGE. So Thank You William for sharing. I THANK you for continuing to share your KNOWLEDGE TO THE ONES THAT ENJOY YOUR INTELLIGENCE. AGAIN THANK YOU.

Please continue with your method of teaching and instruction, it is the best I have found. I'm a retired machinist and finally got around to building my cross cut sled in the past few weeks using your methods, it is fantastic the results that are achievable are heartwarming to a guy that has dealt with .001" and less for the past 25 years on a daily basis. This kind of accuracy in wood working really peaks my interest and keeps me excited about a wonderful hobby. Thank you for all that you have given us as a teacher and a craftsman.

William, Please keep doing your videos and helping the rest of us! I for one really appreciate the time and effort you put into them. I may have had to watch the sled video a few times to understand exactly what to do. Even after that, if I didn't want to do it and go back to making "close enough" cross cuts I can use the framing square method to build a sled. Explaining the math or showing people how to make stuff with precision is interesting and shows what can be accomplished. People, if you don't like the video, stop watching. It's that simple. To make a negative comment about something you got for free makes you a complete jerk. Please just go back to quietly doing it your way and be respectful. William - Thanks again for your videos. I'm becoming a little better at my craft each day! :-)

4 1/2 years later this and the 5 cut method vid are superb and have got me to a level of accuracy I had only dreamt of. I have used both vids several times. Keep doing what you're doing and ignore the fools.

I enjoy your videos, but I knew I would as soon as I saw you using calipers an speaking in thousands of an inch. I recently acquired a large heavy ornate picture frame and wanted to cut it down, so, I built your miter jig, it worked like a dream. Thanks so much for your video, you taught this 74 year old dog a new way to do things.

Mr. Ng, here's the thing with regard to your videos, math, and people complaining about difficulty. Screw 'em! You're demonstrating precision ways to make jigs so that using them will result in precise results. There's a reason why 5,000+ liked your video. I kinda struggled with you 5-cut method of squaring the fence to the blade and once I slowed down and did the simple math and went step-by-step, I was able to square my fence to < .0005" after the 2nd attempt. This has helped me make safe and precise cuts quickly. There's always gonna be some whiners and complainers on KZfaq, but you'll rarely if at all see those people posting videos that are better. Again, examine the complaint. People seem to be too lazy to strive towards higher quality work and would rather accept non-squared cuts as 'good enough'. Oh well, let them do their thing. You had magazines calling you to cite your work and as of today, 02 Aug. 19 @ 2044hrs, you have

I first saw your 5 cut method about 2 years ago and have seen it elsewhere but always remember your video as a lesson from the master, well presented and easy to follow. As far as negative comments go I am sure they can be measured in 0.0001 as well. So now I go forth to apply the William NG method. Thank you so much.

I'm sorry, don't read comments. I was amazed of how accurate your work is, and that's a bar I'd like to reach. Thanks for taking the time to make videos, and sharing your skills with us.

Your 5 cut video you mentioned is the reason I watch your videos. It made me a believer of the 5 cut method. Keep up the good work.

Many have said it already, Don't let few whiners let you down. Focus on the hundreds that do appreciate it not the few that don't . I was going to build a sled for years. It was your video that made it so easy i finally did it. And I used the calculations! They aren't that hard. In fact they are more helpful as I continue to check the accuracy of the sled.DON'T CHANGE A THING. Love this one and will now add this to my current sled. Thanks William for all the videos. Hope you do one sometime on calculating compound angle and making the right settings on table saw.

First sled I built is a direct copy of the one from 5 cuts. The background "math" is essential for those of us who actually want to learn the How of what you do, this allows us to work from principles we understand, rather than trying to follow a recipe. From understanding comes problem solving, which ultimately allows us to create our own solutions. Please keep up what you do, way better to smarten the audience up than to dumb down the content. Thanks for sharing and cheers from BC!

I wouldn't worry about the haters. It seems some people struggle with math, and have learned to hate it. I've been a woodworker for nearly 50 years, and who says you can't teach an old dog new tricks. I just found your video on the table saw sled, which led me to this video. Both are excellent. It's clear you are a teacher. I'll be watching more. Thanks!

Ignore the trolls and haters. I love your videos, explanations and teaching methods.

It's funny that he said people were rude to him about how precise the method was. Now just about every woodworking KZfaq channel has a video about how to use "The William Ng" method. You're a legend William!

I used your 5 cut vid to make a sled that produces perfect results from a crappy saw. Thanks for sharing your knowledge. Ignore the downers.

As always, William, thank you for the thought and effort you put into these!!

Every math teacher I had growing up said there are real world uses for everything I’m telling you. He was right! Thank you for your inspiring approach to things.

Thank you so very much for making accuracy obtainable. Your teaching method and content are not only educational but enjoyable. The complainers are just lazy and probably inefficient. I'll stick with you and learn to do it right.

So glad your making videos again.

William I think your skill as a woodworker is on another level from the vast majority of KZfaq woodworkers. I really wish you could produce more content. I love your style and the accuracy with which you explain your reasoning and strategy. Please keep doing exactly what you're doing...except maybe do it more.

First thing I want to say is that you are the master! I’m a 78 yr. old retired machinist and I love the fact that my sleds are accurate because I used your methods to achieve that accuracy. Those negative comments are coming from “O’kole Pukas” so pay them no never mind! I’m a long time subscriber as I realized years ago you had the right stuff. 👍🏻🖖🏻

Love that you're still reading the comments 2 years after putting the vid up. I'm a weekend woodworker (I work with lathes, mills and CNC machines in my day job), and I used your methods last year when I made both sleds. Being able to quickly cut accurate angles makes my carpentry much more enjoyable - not necessarily better ! - and enjoyment is what's important to me. At the time of writing, vid has 225K views, 8.2k likes and just 94 downvotes - I think those figures speak volumes. More please :D

Seriously best videos I have seen on KZfaq ever. Thank you William

This is the first time I ever comment on KZfaq. I want to send you my support. You're the man. Don't worry about the trolls. They will never be like you. I thought your explanation and math were very interesting and useful. Thank your for taking your time to explain things so clearly. Please post more videos. Please teach me more.

William you have done it again! I have been hating all the 'So long as both sides add up to 90° it will be fine' videos. I found this video yesterday but the sound was not working for me, but thank goodness it was fine today. Now I have an approach to achieving acceptable accuracy, and I offer my sincere thanks for demonstrating it. I started my working life as a toolmaker, and finished it running the external instrument calibration and repair contract at Ford UK Product Development, so it is important to me to be as accurate as is reasonably possible. I am enjoying working with wood in my retirement despite the frustrations it has with it being impossible to work to the tolerances I was used to, and even when you got it close, a week later it would be miles out. But that is no reason not to do our best, and I thank you for giving us the tools make that 'best' a whole lot closer than other KZfaq channel presenters offer us.

Thanks for all your works. Much appreciated. The best way to prove this works is to go ahead and make a square frame out of wide stock using the left side. Then again using the right side.

William, your method and presentation are exceptional. I fully appreciate the time and effort you have put forth in sharing your knowledge with us. Please continue, and know that the material that you are providing is put to good use.

Your methods and explanations are perfect. Appreciate you sharing your expertise. THANK YOU!

I watched your video a few years ago but wasn't ready to make a sled. I was so impressed with your method that I remembered it and came looking for you. So glad I found you again now that I'm ready to make one. Thank you for sharing your knowledge. Just ignore the nay-sayers.

Thank you for the very useful video. Personally, I have tried the cut-and-try method and wasted so much time I am delighted to find a way to get the the real solution with math without wasting so much time and material. Please do not be discouraged by viewers that don't get it.

Respect William! Your videos are an inspiration.

You are a very knowledgeable person thank you for sharing. I appreciate how you take all your dimensions to the thousandth, I find my self using my old tool & die tools in the wood shop all the time and trying to work to those tolerances with machines a woodworker has. Great video William :)

I just got to the point where you calculated the error and then used a feeler gauge to shim the miter piece. I said out loud “I’ll be damned”. Math doesn’t scare me but my adhd will sometimes kick in and say “I don’t feel like figuring all that out right now. You rock dude.

William, having read some of the comments here, there is no reason for me to say much, since I would be repeating all the praise that is rightfully heaped upon you! When I saw your video on building a table saw sled a few months ago I was blown away by your presentation. Not surprisingly, the guy at Kings Woodworking (who himself does great work) gave credit to you for the 5-cut method. When I finally get around to building a sled, I know with your video nearby I will be building it correctly.

First, Merry Christmas! I don’t usually comment on videos, but after watching several of yours, I want to. Thank you for taking the time to make your videos and showing everyone that there is more than one way of doing most things, and that if you put in a little more work on the front end, you won’t have problems on the back end, or at least as many. I have been in home building & renovations, for the past twenty years, and build most of our cabinetry and doors. The little adjustments you are taking the time to do up front, make the installation, and use of the final product, much better. A lot of contractors have a hard time understanding this simple concept. Thanks again and keep the videos coming.

Wow! This is the first video of yours that I have viewed. Absolutely brilliant! I love precision and it's an honour to watch and learn from your video. Anyone who hates your content either doesn't have the intelligence to understand what you're saying and doing or doesn't want to improve their performance. Thank you for posting. I've just subscribed and will be checking out your other videos. 👍

William: I have a business that required machinist level precision on my wood blanks that I finish on a CNC router. I make 100's of pieces at a time that all need to be within a few thousands of an inch so pieces fit together properly. When I made my cross slid sled, I used your formula for ensuring a perfect right angle on my blanks. Thank you for making it easy. For me it was a life saver. Math is so important to me and I stress it to my sons who are my business partners. Work at times is a lesson in math. Keep up the great work. Master Monk

Don't let internet a holes bring you down. People don't have any manners or respect anymore. Keep doing what you're doing. To hell with the haters.

This is fantastic. I've had a "picture frame" sled for a while and do need to alternate sides. This method is great - I will use it just like I used your 5-cut for the cross-cut sled. THANK YOU Sir!

Great sled videos Mr Ng, especially for beginners, as for those who find simple math beyond their capabilities and intelligence, well they maybe shouldn’t be allowed to be using sharp power tools or even butter knifes and spoons without supervision. Im an old retired pro, still have the shop just don’t work in it ten hours a day anymore and I believe your videos should be required viewing for every high school shop class in the country. Great job sir keep them coming.

Regardless, EVERYONE is using your formula!!! You are by far the most competent wood-working instructors out there! Thank You for all that you do.

Mr Ng, Your 5 cut method was an inspiration to me. But as a woodworker who is always trying to improve a method to simplify for the not so experienced....After I cut my sled with my blade, I attached the back fence on one side then I used a 12” long piece of keyway stock an 1/8” thick (the width of my blade) and slipped it into the slot. It fit snug enough to stay on its own. Then I took my drafting triangle and butted it up against the keyway stock and aligned the back fence with it, clamped the fence down on both ends, then affixed both ends. After making the 5 cuts I was off .0023. First time I had ever gotten that close, thank you. Remember the adage: The difference between a carpenter and a woodworker is about an 1/8”. Until the person can breach the mindset of a carpenter mentality what you are teaching will fall upon deaf ears. In this world there will always be a place for both. For many years I have said I was a rough carpenter, my mindset has changed and so now I say I am an apprentice woodworker, and will be until I pass from this world.

Dear Mr Ng: I am so sorry you had to be insulted by people who dislike math. You put in an amazing amount of thought and work just for our benefit. I don't get it. People would never admit they never got the whole reading thing, or ..."sorry, I sign my name with an X." ......just never got along with writing or typing or the alphabet. But they think its perfectly OK not to understand 8th grade mathematics. How did they get their HS diploma. And if you cant do middle school math remember the Fifth Amendment: You aren't required to admit to the the whole world what you cant do. I brought your new video with the miter cuts and the A and B similar isosceles right triangles to my colleges here and we had a very good time marvelling at the genius of woodworkers. You, Mr Ng, are making the world better for all of us.

Greetings Mr. Ng Thank you. I appreciate your knowledge, skill, patience, willingness to risk, sense of humor, and the quality of your work. The tools I can afford are not of the quality to which you have access, however, following your guidance, I believe I can attain similar degrees of accuracy and precision. Over the course of this winter, I have not had access to my power tools, so I have made use of the time to watch dozens of projects and instructional videos on KZfaq and I have begun to develop my skill using non-powered hand tools to make several projects. I am looking forward to implementing many of the techniques I have studied. Thanks again for the quality of your presentations. I look forward to learning more from you. Handy Andy PS - thank you for following a no sound track policy.

William were all still here for you and anxiously awaiting more of your instructional videos.

There are dozens of videos on KZfaq showing you how to build a miter sled that'll be "good enough". But with just a little more effort, you can build one that's perfect, and this is the method. Thank you Professor Ng.

Great video and amazing info. Thanks for taking the time to teach us. Please don't listen to those that think simple math is too complicated. If they want to woodwork by the seat of their pants, let them. Woodworkers that take pride in their work appreciate new techniques and lessons from master craftsmen. Thanks again from a brand new woodworkers :)

Thank you sir, you are an EXCELLENT teacher in woodworking and I very much appreciate the attention to detail and your aim for precision work, even in woodworking. Also thank you very much for your 5 cut method; your video and explanation was very easy to follow and rather simple yet quite ingenious. I now finally have a sled I can trust to within a tho and I couldn't be happier, no more frustration with not being able to simply make a perfectly square cut!! (that was getting annoying....). Please keep up the videos as long as you can and ignore the trolls. The vast majority of us highly appreciate your content and your teaching style. THANK YOU!!!

William I can't thank you enough for your contribution to CLASSIC and PROFESSIONAL approach to woodworking. As others have said, some people are use to a hamburger and are satisfied, I'd rather prefer having a steak with all the trimmings and be fulfilled. Class is class and crap, well it's just crap. The ones who don't appreciate what you have contributed are simply jealous they can't do as well. Go find a safe place and wait for their participation trophy. Keep doing what your doing it is true woodworking at it's finest.

People are so rude. Your videos are so good and I think your character as a person is inspiring.

I've been waiting to see your solution to this problem since I found your "5 cuts" video. Mine was more 'trig-y' but got me pretty close. I really like your use of parallelism to get the fence made, so I'll try yours and see if I can do better. Thanks for the great content. Try not to let the negative crowd get you down. It tends to be louder than the positive crowd, but it's definitely a very small percentage of the overall impression you're making.

Excellent video, excellent instruction. This and the 'five cuts' are absolute reference material. The heck with all the haters. They are just ashamed that they can't add up, subtract, multiply and divide.

6 days later… built the sled , sweet method works well nice miters thank you for taking the time to share

I’m new to wood working and this method removed all the cobwebs from my brain . Other videos do not go into explanation deep enough with basic words . Thank you

Hi William. I'm all the way over here in Australia and I love the content you produce. Are you still making videos? The most recent couple seem to be a year ago. Have you done any since then? You describe things in such a clear way, and your ideas for workshop efficiency and accuracy are so simple, yet ingenious. Thank you.

I would pay for this information. Great content. Any way i could help you out, let us know. Amazon cart, etc. You definitely deserve to earn money with this info. For guys like me that didn't do well in geometry, you're an asset!

William, ignore haters. That’s all I got to say. There’s “feel good” woodworking, then there’s woodworking where you know how to make shortcuts to make it work, and then there is the next level where you must pull out the calipers. All levels have their place. Thank you for the videos.

William, you're right haters gonna hate!!! Ignore them! Very few people on youtube that I actually remember their name, yours being one of them. I just recently bought a house and purchased a used table saw and after searching for how to clean it up, I did a search for your name so I could find that 5 cut video! I WILL be using it when I build my miter sled! Thank you so much!!!

This is AWESOME, Thanks a lot for sharing your knowledge XD

Hi. I can see that the mean comments have an impact on you. But I don't think you should keep focusing on them. Move on and realise that the majority of people enjoy your videos

I used your 5 cut method when making my sled.. I got -.001!!!!! Thank you for sharing it with us. Please don't let the haters get to you! A lot of us love the accuracy!

You are the Master of sled making with the highest accuracy ever. Thanks so much for sharing with us who do appreciate your expertise.

My rule of thumb is that if you get less than 10% negative on your ratings, you're probably posting a good video. This video has a down vote of 0.8095238%. NOTE: That's PERCENT! William, your videos are international treasures. Please keep making them for those of us who want to learn from you and benefit from your amazing skills. Thank you!

Thank you sir...Another great tip....it makes perfect sense, just like the other one...you should tell those trolls to shove their ignorance up their dust collectors!

Thank you. I watched this this morning after spending all of yesterday trying to figure out how to dial in 45. Now I know.

Woodworking for me is fun but imprecise. It’s now driving me crazy. I am glad you teach precision as I am learning from you and having fun with added satisfaction. Let the haters continue with their imprecise ways while be the precision teaching you. I am so glad you are doing this. Cheers!
