I love that your channel promotes the hand-made approach. There seem to be whiz-bang tools for everything these days, but watching someone make things from scratch is so much more satisfying. You're a great inspiration to little makers like me who have only a few tools to stick at it!

The pressure bearing is flattening the knurl as it’s formed. The process both creates and destroys the knurl at the same time. What you’re creating is more a pattern than a knurl. It’s was hard to watch but appreciate your industrious enthusiasm. Sometimes okay is good enough. ‘She’ll be right mate’.

Dear Neil, brilliant take on an old tool, especially for the 95% of us that don’t have a metalworking lathe.

This is a cool experimental build. I really appreciate it when makers like yourself show the trial and error, rather than just chopping the footage out. Everyone learns something about the materials and their limitations. It also means that people can think of alternative ideas for the design without having to see what works and what doesn't. Good stuff.

Every woodworker will enjoy having a metal working lathe. It makes making jigs and parts so much easier and precise.

Absolutely love how you show the Good, the Bad and the Ugly.

Love the file idea as everyone has one! I'll be working on making that more practical in the near future. As for the knurls themselves, if no one's mentioned it yet: the straight knurl only needs one wheel. The diamond knurl normally uses two as you have them, but they do make patterned diamond wheels where only one would be necessary. Bear in mind that the distance between the knurls is a product of the diameter in which you're knurling. Also, the diameter of the bolt head is increasing due to the displacement of material caused by the knurling wheels. All in all, the file trick is indeed the most inventive and if perfected could be of huge benefit to the weekend warrior. Tha is for the videos and keep up the work!

I really appreciate that you show the processes you used to get to the finished product!!! I am glad you are "man" enough to show your errors, failures, or not-liked end results. Folks have said the "necessity is the mother of all inventions."

The more of your videos I watch, the more impressed I am. I completely understand thinking a project will be simple, and thinking up improvements while you're in process that make if more effective and versatile, yet make the creation of the jig more difficult.

Great video. I learn a lot by watching how other people work and problem solve. Thanks for sticking with it.

I love how much I see makers on youtube showing their audience more and more of their process instead of just a quick A to B guide. This was a really educational experience and entertaining as well.

Thanks so much for your videos. I often learn a lot from them. When I was a student in school, we used to do knurling on a metal lathe and we used motor oil on the knurling tool to lubricate the tool and the job. It tends to make the cutting process easier on the tool and the job... Thanks again for your efforts. Great job.

I love your projekts. It's really cool that you don't give up as fast as we see for usual, but you don't just give up a bit later, you give it hundred new tries if nessesary. Until its works. That's awesome and i'm really impressed... thankyou for your videos!

That works a lot better than I would have thought. Pretty cool.

Congratulations Pask,you never give up ! Very good idea . Before your video I thought that a knurling could be done only with a lathe.Thanks.

Wicked, Jig would be great for someone that restores old vintage equipment. :)

Great video! This is just what I need too. I made marking tools, push bars and sticks out of scrap exotic woods as presents for some woodworking friends but I couldn't 't find a reasonably priced knurl nut in the size I wanted without paying a fortune. The plain head bolts in brass and stainless steel are easier to find in my area and on eBay so now I can start making my own thanks to you my friend. I just started to weld as well so I will be adding the "lip" part onto the jig. thanks again!!

These videos from you are,in my opinion,the most inspiring and helpful around. Most of the videos I watch try to suggest that all goes smoothly ALL of the time. .....your videos are more like my world,some bits go well,some don't . So thanks for your honesty and for showing that persistence,like yours,is SO important.

Thank you for showing us the entire process including your setbacks. It is encouraging to me as a beginner that not everything works the first time.

It is good that you showed all the 'steps in the development' of the jig ( I will not call them failures, they are learning blocks!) Project glitches are how we learn, sailing through start to finish with no problems is simply doing something we already know. Enjoy your channel!

Came here from the scrap wood hand planing tool. Beautiful work all together!

Nice work! 20 Ways To Skin A Cat is the saying we use in the US. A third knurl where the bearing is may be worth considering …. Commercial hand knurling tools available in that configuration. Love the vids folks like you make using basic tools to do fairly complex projects, especially where the process is the main emphasis vs showcasing a collection of tools. 👍👍💪💪😎😎

Your talent with woodworking precedes you, but I notice the spring-load center punch and when welding in other videos, no gas shield cover so it must be flux wire. As a retired vehicle tech, these things are not spoke of, but I notice and appreciate the metal talents you present us! You have names for the some woods you use, never heard of them, but nice for where you live. In Omaha, NE. we have few choices for native woods species, as exotic woods are out of reach for the full-wallet changed. I am going back in time within your channel as time permits to watch everything PASK MAKES. In my book, well worth it. Love it!

Your editing and camera work are so incredibly good. You make it look easy and effortless, but I know how much work goes into it. Keep sharing!

WoW - What a way to put a professional touch on any project. Thanks for not giving up and getting it done right. Showing your trials with not so good results can save guys like me from trying something that isn't going to work.

Thanks, I was lost trying to find a cool pull for a bandsaw box I made. The rounding and polishing of a bolt was something I never thought of and it looks so custom-made and special. Keep up the great videos.

Another modification of the copper pipe idea below would be to use a copper pipe cap, you could epoxy the bolt inside the cap and easily knurl the copper. The cap may be parted by use of your drill and a sharp tool, or double stack the knurling wheels... This is the first of your videos that I seen, I'll have to check your page for more !!!

Thank you for sharing. I used a little oil on the knurls and it seemed to work a little better.

I love that you show us when things don't go according to plan.

Ingenious. Interesting to see how a woodworker approaches metalworking problems. BTW, the knurls and workpiece need to be swimming in cutting oil (dark sulphurated, as in pipe threading oil) to ease the impression into the workpiece, and to carry the swarf away. It will stain things, so keep it away from nice bits of wood. If you replaced the opposing bearing with another knurl, it would help avoid flattening the new ridges by the flat surface of the bearing. For the diamond knurl, use an extra of either hand and lay out the pivots so opposite-handed knurls are nearly opposed and the extra is just to guide.

very clever! loved your problem solving!

Мужик! Ты гений! И больше всего мне нравится, то что ты говоришь-" не знаю как получится, давайте попробуем! Не попробуешь- не узнаешь!"))) Молодец!!!

YOUR A DAM GENIUS!!!!!!!!!!!!!!!!!!! Straight from the mouth of a 30 year toolmaker/machinist!!!!!!!!!!!!!!

It’s really cool that you show the different techniques that didn’t work. It makes me realize that no matter how good you are there will always be hiccups in your planning

I enjoy your videos because you show the failures along with the successes.

It is refreshing to see something 'not go as planned' for you, and then see your process for figuring it out. Thanks for the humility to share with us!

Brilliant jig, thanks for showing what went wrong so it helps me if I make one. Very keen to try

Thank for putting the whole process in the video, including the false starts - the development process just as interesting as the actual physical process.

Neat idea! Try some cutting oil next. When we knurl on the lathe we use a large amount of oil. I brush it on thickly continuously, but if I had a way to flood it with oil while cutting I would.

Thanks J Dewitt for the idea. This is so cool. And Neil, it always amazes me what you are able to do with metal fabrication with simple tools.

It is not the first time you show trial and error. That's a winning concept. Makes it so interesting to watch. Well done!

Love the experimentation and problem solving.

You are a brilliant man and I can't tell you how much I enjoy seeing you experiment and troubleshoot. It must be even more satisfying to build something with tools you've created yourself!

Hi Neil, I manufacture brass door hardware. We have a decorative hinge finial with a 90 degree knurl. Very coarse. Due to a very thin section on the part we could not produce this on the lathe. So we built a similar tool. The brass part sits in a ledge. One side is stationary. The second side slides relative to the first via a very large lever. We milled two knurl plates from tool steel and heat treated them. We can adjust the gap between the plates to get the depth of knurl we want. A couple of things I noticed. When you are using the cordless drill it's wobbling a bit. This is leading to an uneven knurl along the width of the face. Also, the pressure required to achieve a deep knurl is considerable. You might try narrowing the face to be knurled. Pre-chamfering both edges would do that. That would apply that same pressure to a smaller area. And you might try a convex knurl. All in all a very interesting video and great results.

Very interesting prototyping phases. It's amazing how something may seem very simple on the surface, but once you try to build a tool to make that 'thing', you realise everything hidden from view. The forces involved in knurling (and turning and milling of metals in general) are immense! That's why all the machines and tooling are so strong and heavy. I'm not surprised that you snapped those bearings in half in no time. They just can't take the loads involved. 😎

I enjoyed the process, the trial and error very informative, thanks

King of the jig's. I also used one of your jig in my video about making chisel handles. Thank you for inspiration.

I appreciate your honesty in showing your failures and mistakes when you are making m video-it encourages me to not give up when attempting something new; just keep on persevering. 👌

I especially like the thoroughness of documenting your thought process and problem solving. Thanks....

Cool idea. I have used 2 files and rolled a bar between them to create a knurl. One file on the bench and push and pull the other over the bar or bolt. Good for creating a bit of interference on a fit.

I appreciate your perseverance. Plans A, B, C, etc. That's how many things work out.

I like that *trial & error* approach. Well done.

I like it when if welding is nice, but not totally necessary the maker either uses bolts or at least states that bolting is a viable option. I also appreciate seeing the steps in developing a project. Thanks

Just look at the thumbnail of the 7 homemade marking tools that youtube recommended at the end. I already see 4 uses for these screws! Outstanding work Pask.

Thanks for sharing the whole process - all the trials and experiments. We can learn at least as much from the way you think and tackle difficulties as from the final result.

great video. I agree on all the postive comments of the other guys. I submit to you an alternative idea. A jig with 2 twins parallel files. The rounded bolt squeezed between them 1 - Regulable distance between the files. 2 - One file is fixed (solidal to the jig) 3- The other file can slide, leaning on bearings (many, big, robust, bearings). maybe it is better that the file does not len directly on the bearings (some thick bar in the middle) 4- the sliding file could be moved in both directions either with a hammer or, in some way, using a drill-screw-bolt system

Me: does woodwork at school for the past 3 years. Me still: rewatches Pask Makes cause his videos are so inspirational and informational

I used to work on a capstan in the fifties making parts for combination locks and knurling was used to imprint the numbers

Amazing job! It is a pleasure to see you working! I really enjoyed the process! I am a believer that little details make the difference! And those knobs you make are full of them!!!!! Thanks for sharing!

In the machine shop I had a knurling tool that I used on a lathe. As the part turned you increase the pressure. That is exactly what you're doing. Now I want you to try putting a cutting oil on it like when you tap a hole. It made a big difference on the lathe. It stopped the chipping and messing up the knurled part. I think you can buy knurled bolts and screws cheaper than bearings. hahaha. Good luck

Thanks for sharing and bringing us along on the journey of the build.

Love the idea, hopefully a follow up video will come when you get the finer wheels.

I saw a knurler made from flat stock cut into a Wye with both knurles on the ends of the Wye and the piece is rotating and you push the Wye against it. Really good cut and fast.

Thanks a million for this one! I’ll make one this weekend..

Brilliant. Watching you iterate through was just fascinating. Thanks for bringing us along!

It is things such as this that keeps a private shop self-sufficient and out of the parts stores. Cheers! Mike

Really appreciate your effort.. most important thing is that u almost show all the errors u make, that really replenishes us to have more ideas to fulfill them.. good luck,luv from India 😃

This is just what I wanted to see. I need brass and stainless knurl screws for some projects coming up and now I know how to make my own. Thanks! ~Dolly

i love watching your videos !, im trying to watch them all when i have a break from making my woodturning videos.!

Knurling Techniques have always fascinated me. & Thanks for all the awesome videos.

Pask, that is so awesome, man. Great work. Love seeing all the trial and error and you working through different ideas. Great stuff.

haaaahahahaha! God bless'ya, Oz! That vice technique had me laughing with great appreciation. First thing tomorrow, I'll be out in my little shack, making some homebrew knurled screws and bolts to go into my home made woodworking tools and other projects. Thanks,

Thanks for sharing the failures and the successful finale!!

That's a very unique way to do it!

Great content. I often end up working nuts and bolts into jigs, nice to learn how to knurl using a file. I use a coupling nut to hold and protect threads when chucking the nut into the drill for spinning, instead of taping the threads, but only works on the smaller diameters. 1/4, 5/16

Got his bearings while knurling one out. Very important.

Learning from your mistakes was very satisfying. Thanks for the video!

Just like prototyping! Loving all the iterations and problem solving.

Your channel is excellent. I most like your videos showcasing DIY engineering projects. One of the most satisfying things in the world, which can be seen clearly in game design, is the sense of constant progress. Using the tools you have to make tools that help you make new tools. It’s a beautiful thing really. Looking forward to your videos

one of those things that when you need it, it's super handy.

Looks good! Great trial and error process.

Thanks for showing the process that you went through to get the working model. Well done.

What a craftsman!!!!! Thank You!!!

That knurling technique is really cool

Nice to see the trials and tribulations. Great video

I like your fixture. It is quite clever. I don’t know if this has been said yet, but I would swap out the bearing for a third knurling wheel. The flat bearing pressing on the small points created by the other wheels will work to flatten them, and constantly work against your efforts. When I knurl parts on a lathe, my preference is usually to use a constant stream of compressed air instead of oils, because the air will continuously evacuate the chips that are being created as you are knurling the part, but oil tends to hold the chips on the part which can ruin the knurl. The air does also help to cool the part, but perhaps less efficiently than the oil would. It is a trade off but my experience has shown better results than oil. Hopefully this helps.

Congratulations! it's a very good idea! A little advice: if you put cutting oil on the bolt head, you probably have a better result with a lot less effort on the bearings. Well done! Continue your ingenious work.

Way to hang in there! I enjoyed seeing your trial and error method.

I love toolmaking vids. The progression from idea to final working model is very interesting. More please. 👍

Great effort mate! Really appreciated how you didn’t give up after the first failure. It paid off in the end.

Glad to kept your trial and error process within this videos. Shows how much of an engineer you truly are.

If the ball bearing fail I suggest you use cam followers since the OD ring is thicker. Also look at centerless grinding set up where only need two wheels and a rest to stop the head from moving out. The two wheels are over center so they push the head against the stop but the force is low because the angle off the center line between the wheels is small, sine of a small angle is very small where the cosine is very close to full force.

I did the same thing using a large rotary pipe cutter and substituted knurling wheels for the two bearings and a bearing for the cutting wheel, worked OK.

A great example of trial and error problem solving!

Very interesting to say the least. Thanks a million!!!

Ingenious! I appreciate this channel showing the learning process of making something like this.

Keep the drill spinning as you tighten the vice to keep the momentum going . This may allow you to apply a more continuous smoother force rather than stopping and starting

Very useful tool Neil, finding time to dream up and put these ideas into action is a skill and ability you have in spades! Well done!

Great to watch your prototyping process! Neat tool! Something I can use.

Good to see you stick it out and make this happen. Something I take for granted on the lathe, you have made into art without one. Well done, really clever!
