Watching these kind of videos ensures I will never be able to retire as all my savings constantly gets diverted to more tooling!

Love the "dad" draws. I've got the same. Can't bring myself to change them. It's like keeping a part of your father in the shop.

I haven't had anyone to guide me, you're my mentor Adam! Thanks for taking the time to mentor me :)

Thanks for another good one, Adam, you are a great teacher! I am 69 and have been model engineering for a year, learning much from you, Keith Rucker and Lyle P. Keep 'em coming!! John, Cardiff, Wales.

Perfect timing! I have been watching you and the Keiths and a lot of the other KZfaq machinists for a few years and I just bought my first lathe. You and the others are so generous with your time and talents. Thank you so very much.

My uncle was a machinist in early 80's and he has always had this great since of "patience". He has always told me "slow down what's the rush". It's something I see in you and your videos. Keep up the good work!

Great video. I thought I knew all I needed about reamers until I watched this! Your take on cutting tools, inserts, angles etc would be a good topic I'd like to see.

Thank you for reaming me out properly! Seriously, I appreciate the instructions. We have very few reamers and I realize now we have a Morse taper reamer that goes to our old drill press. Greg

This is a really cool series of episodes. I think you're making a huge contribution to your trade. Word of mouth is the old school way of learning any trade, and your series is bringing those basic skills to a huge group of people in that old school way. (Maybe with fewer kicks in the butt.) Way to go, Mr. Booth.

Thanks for making these videos. I know alot of the older guys probably already know this stuff, but its great info for the newer guys. Keep up the great work Adam!

Thanks for posting. I bought a medium size lathe 2 years ago, got enough tooling to start using it almost every day for my DIY projects. Your videos are much appreciated, plus you look like a nice guy.

Thank you for sharing your knowledge. So many Machinists nowadays don't like to share knowledge. So I really appreciate you taking the time to videos like this.

Thanks Adam. I have the same drawer full of adjustable reamers that were passed down. I have always treated that drawer as sacred ground. Never used them. As a result of your post, I am going to give-em a go. Thanks again for the time and info.

Adam, thanks alot bud for showing us newbies and teaching us through your videos. There is alot of things that I needed to figure out around the shop and I always go to your channel first. Thank you.

Wow man...you are blessed with being a machinist and having so many good quality tools in your incredible workshop

Don"t mess with the tool box!!! That makes you think about your dad every time you get in there. Another great video. Thanks

This is an exceptionally informative video, Adam. Thank you. You are a great instructor.

It is awesome to learn something new from one half my age. I thank you.

Adam, this was a very informative video. Nice work!

Thank You, for the info on these different reamers. Every time I watch your vid's, I learn something new. Thanks Again!!!!!

I was going through my inherited tools this morning and found a big beautiful set of these funny looking drill bits which I now know to be reamers. Thanks for the vid.

Great video. I'm new at this and you explained a lot to me. Thanks again. The question I had was answered by you already when someone asked when to use a reamer. Great videos. Thanks for not forgetting about us new guys. Enjoy your videos a lot.

Excellent tutorial. Cleared up a couple of things I didn't know. I do know not to turn a reamer backwards. A few years ago I ruined a set of adjustable reamer blades that way and, like they say, mistakes are the best teacher.

perfect timing. thank you Abom!

There's a lot to be said for keeping things the same. I respect this way that you honor your father.

Never gave reaming much thought till I needed one, now I'm learning all I can. You gave some valuable information, thanks.

Thanks for the video, I bought a bunch of tooling from a friend who needed some cash and have been trying to learn as I go along. Not easy at all but thank god for yt and people like yourself, K Rutcker and pete222. The simple videos are sometimes the most helpful. Keep up the good work and remember not all of us are machinist and I will continue to watch and learn.

I am from India 🇮🇳... Great theory over Reamers Sir.. U Solve my confusion when I reading Reamer and their Uses over my book.. 🙏

Love your videos. Stumbled on to the machinist type channels with Keith Fenner and Keith Rucker. Found yours as well. So I started with your first and worked my way up to this year so still catching up. Your videos are easy watching and full of information. Even though I don't do any machining it has changed how I tackle problems I may deal with on a day to day basis. Basics are always good especially for people like myself Many Thanks Adam

Thanks for the great instructions, Adam! I learned many things new to me.

Great topic Abom. Thank you for sharing your knowledge have never had someone explain reams and shown the difference between the many types. GW

Hello from France Adam and thank you for this very interesting video. You mentioned that you don't rely on the reamer for precision hole. For precision reaming with accuracy close to 0,01mm, you can use a floatting chuck. Its a pricy extra accessory, but can be found for adapting on a Lathe tailstock (reamer is fixed) or milling spindle (reamer is turning). It's used to correct misalignement between the axis of the spindle (or tailstock) and the hole to ream. It also gives the advantage of letting the reamer following the true axis of the hole. Generally speaking, the reaming using floatting chuck can have the tolerance of the reamer itself. Floatting chucks can be found with Collet MT or straight flange mounting, and reamers can be mounted with ER Collets, or MT attachments. Some models can even allow internal coolants to pass through. Have a good day ! François

thank you, on behalf of all us newbs! :-)

Thank you Adam, I appreciate you talking about basics like this. Thanks again!

sometimes you can use a box socket as a handle by turning it upside down and placing it on to the reaming tool, get 12" of bar and weld to a nut in the centre, then put the nut inside the socket, use the square drive size 1/4" 3/8" 1/2" n so on that fits your reaming tool size, this should be as good as any handle an hopefully it helps somebody thanks for the vid Abom👍

Once again, beautiful stuff. Crystal clear and I just keep learning. THANK YOU!

I was not aware of "never" reversing a reamer which makes perfect sense. Thanks much. It is the same for a file and I often see KZfaq videos where a file is used in a scrubbing action by someone working on a project. Aargh!!!!!!!! Always love the "Abom Torque" reference which is self explanatory.

Thanks for uploading these basic videos! I love to see cool basic stuff like this explained in a way an average joe can understand.

Hey Brian, could not agree more re tooling and thanks for sharing Adam for sharing. Kindest regards. Joe.

thank you sir very very much for taking the time to share your skills i am starting at the very beginning at 50 rears of age i have a lot to learn

Abom, thanks for these videos, I appreciate the two wrench reamer handle solution. I will definitely use it in the future.

Getting ready to buy some reamers and needed more knowledge. Great stuff for a new to machining guy, Thanks Adam.

I was looking for info for pull reaming and the reaming stock allowance/removal, but I appreciate the additional knowledge about reamers. Thank you sir

Excellent detailed description, Adam, thanks!

Ahhhh, great video for the work week. Came home from work and school to see the notification. Always good to see. Thanks Adam!

Good one Adam. Thank you for this great video.

Really enjoyed your lesson on reamers Adam. A lot to learn.

Thanks for this informative video, I used a reamer a few times but good to learn about the different styles.

great vid bud, always cool seeing different stuff...

thanks Adom79, these intro videos are great for us non-pro's.

I have cleaned up the tailstock on 2 lathes with that tapered reamer you showed. Worked well as they were not gripping because of burs, but after they did.

Good descriptive video Adam. Nicely done.

Hey Adam great video as usual. After getting rid of some of my Dad's machinist tools (He was machine shop foreeman at CIL industries in Edmonton Alberta) I now truly regret it. Suggest you keep what you got for your future kids. Things change in time sometime things happen really fast when one's not expecting it. Rod

did not know about turning a reamer backwards,good thing I watched this!

AbomTorque! Get some! Thanks for the highly informative details.

Very informative Adam ! I have only used reamers to do valve work on heads .. Thumbs up

That was a great presentation boss thank you. Im new to machining. I. Restoring a 1966 f-100 pick up and needing to learn stuff like reaming kingpin bushings and such az a lot of shops wont do it. Great video👍

I get a chuckle every time you say Abom torque cause I am reminded of Keith Fenner hanging on that ratchet yelling Adam quick i need help lolol

Very informative, Adam. Thank you so much.

Thanks Adam you confirmed something I felt for many years now. I’ve been in the trade for a little while now, about 38 years, and I like you do not use the reamers for the reason that I don’t trust they will cut an accurate size hole. I just settle on boring the hole instead of possibly scraping a part.

you give the best information of anyone out there. Really enjoy your video's.

Hey Adam i dont get enough of watching your videos, they are very useful to me. Oh i almost forgot say hello to Brasil.

Great job Adam! This will be a great series. I would suggest creating a "Tooling Basics" playlist for all of these videos to make it a little easier for people to find everything and have it all in one place. Thanks for freely sharing your knowledge and experience as is appreciated. Open Source knowledge, software, and hardware in the way of the future and we are in the early stage of implementing all three. Peace!

Just starting out in class.. THANK YOU for starting out basics !!!!!!!

Ty so much for all you do. Trying to keep my teenager on str8 and narrow he likes your videos

my understanding of adjustable reamers is that aside from compensating for sharpening you can also tune in running or press fit etc.

Excellent job, thank you for sharing your knowledge! God bless

Love the old tool boxes!

one thing I'd like to add is, if at all possible don't peck with a reamer, you'll end up with a bigger hole, I don't know why that's just my experience. thank you Adam. loving the content. keep it up!

There is a roughing morse taper reamer you use initially to cut the taper then finish it with that hand reamer.

Good video, Adam . I was digging thru old videos hoping to find "salvation" for my reaming . I like you could never find reliable accuracy with my reamers . I was dead-sure I must have been doing something wrong -- could never find a solution to reliably get any better than a thousandth or two -- would always have to rely on honing . Got a "kick" out of seeing your inherited reamer-drawer ! ...... looked very familiar . It's is amazing the weight those old lower boxes could handle -- albeit, not without a little distortion .

Abom rules! thanks for the quality vids!

Very interesting & informative keep it up Adam

Thanks for recognizing us beginners!

Been using reamers for years and I learned a thing or two on here tonight. Evidently I've been doing a few things wrong for years. LOL

thanks for the informative video that explains the tools and the reasons to use them all. Great for the beginners like me :)

new subscriber here @ 20:35 I was waiting for you to mention that part!! that should be like the 1st advise. Great content.

Yep good info Adam---well presented....

Thank you for this. The vid on taps was great too.

When I was taught in school they always said half the drilling speed and double the feed. Works Ok but I always slow it down even more. Was reaming 3/8 holes in stainless a couple weeks back, was getting a almost mirror like finish @ 85 rpm.

Thanks for the help for as you said some of us are new to this world.

Lol! Every other video we hear sirens blasting. Great video on reamers.

All reamers need to be stored with some sort of protection on the flutes. Use either plastic expansion netting, cardboard or plastic tubes, or something if you are going to throw them in a drawer. Stands and indexes are available for fractional, number, letter, and metric reamers in smaller sizes.Each time a reamer hits another piece of tooling by throwing it in a drawer it puts a nick in the flutes. These nicks are all visible with the aid of an optical comparator. Reamers are designed to produce a smooth finish in a hole. That cannot occur when the flutes have nicks in them. The more nicks, the rougher the finish. You are correct when you say reamers rarely cut on size. This is one of the reasons decimal reamers are made. If you want the truest hole to location and size you must bore it. Excellent, in a nut shell, explanation of the reason for never turning a reamer backwards.

I liked this video a lot. well balanced for everyone. (I think) thanks for taking the time.

Enjoyed the video. Learned a lot. Thanks

I know this is a 3 year old video, but I couldn't help commenting. My grand dad and dad were both tool & die makers. My dad was an apprentice just before WWII. I have many of their tools including my dad's Gerstner filled with precision tooling. I open the green felt-lined drawers with a weird reverence and can hardly bring myself to use the tools in my crude metalworking attempts.

Awesome video Adam, basic is real good

Enjoyed the video quite a bit!

Recently had to buy 3.0mm and 3.3mm reamers. I guess this video is for me :-) I'm excited! *starts watching*

Good overview Adam, I'm glad you mentioned the chuck / collet holding thing I've been burned by that before using a drill chuck instead of a collet especially for smaller sizes. I would have liked to hear your thoughts on the actual operation in a machine, like pecking or not and speed, etc.

Thanks for the info! Reamers can be a mystery. I will add to also make sure you measure your reamers carefully before using them. I had the need to ream a 1" hole. I had 4 1" reamers. Only one of them was actually 1". Even though they all said 1". They were gathered from who knows where and a couple looked re ground. Thanks again!

The beauty of a tapered pin is it will release very easy as opposed to a straight dowel, and in toolmaking of die blocks to shoes as in progression dies for instance, a threaded ejector hole will release the die block immediately, straight dowels need to be completely driven out with a hammer and punch, plus two parts taper doweled together can be realigned (moved) into alignment by re-reaming, you can't do that with a standard straight dowel if the alignment is not exactly spot on its time to go with an oversize, I have used tapered dowels recently on several tools I have built, they might be old fashioned now but I think they look much better than a set screw to locate a hand wheel on a shaft, and they work great, Edmund...........Alberta

I have 4 of those adjustable reamers hanging on my shop wall.. Never used them, didnt realy know how to use them. You can use a socket with 12 dividers and a sliding t-bar on those big 4 siders

Very helpful Adam !!!

To get a true reamed hole you need to straighten out the hole from the drilling operation. Most drills will walk a little even with precision cnc grinds. With smaller reamers say used in milling we would use a reground end mill acting as a boring bar to straighten the hole before reaming.

You mentioned not trusting a reamer to hold close tolerance. We had some aluminum parts at my work, about 100 of them. They had a 5/8 inch hole that had to be held at +/- 0.0005. We used a Hannibal Carbide tipped reamer. And the cutting fluid made a huge difference. With heavy cutting oil, it reamed over sized. But with WD-40, it worked like a charm.

I've cheated and used a center punch chucked in a drill press as a guide before. Same idea as a spring loaded tap follower, but I didn't have one of those on hand. It keeps the back end of the reamer from wandering around. Thanks for the info. Never knew what the sprial reamers were for. I always figured it was something for heavier cuts to clear chips.

Thumbs up for "Put some Abom torque on it." 😁

Im very late to this party apparently But Im about to venture down this reamer road for the first time. Gotta Old Cat engine that I need to replace a oil pump drive and the new shaft needs a new hole for a #3 Taper pin to lock a collar to it. Should be a fun time. Its Insane how much money in reamers you have there!! This Tiny #3 I purchased was 60 Bucks alone and its small. Crazy.

Awesome stuff, Thank You!!
