Hey Tom, thanks, glad you're back! Nice tip! Take care!
Thanks Bob
If I could like this twice I would. Great to hear from you again !
Great tip, Tom. Thanks for sharing and welcome back.
Thanks for watching, Lyn.
I've also been looking for you Tom! Glad you're back! Great tip and great video! Thanks
Thanks David
The second you pulled that out I was like,no shit!...Iknow exactly what he's going to do! Honestly,thank you very much..
Tom, I have watched 1000's of machining videos and have never made a comment. Your teachings have really impacted my life. Thank you for all that you do. Glad to have you back.
Thanks Gary
Thank you

Hay tom there are no hands on your clock.
Lol. Some moron actually set that clock out on the street for trash pickup. It is a 170 years old with a wooden movement and is one of the first projects on my list, post retirement.
Tom
Glad to see you back! I'm for whatever format gets you making videos again.
Thanks Matthew
I know I am pretty randomly asking but do anyone know of a good site to watch newly released series online ?
@Paul Jamir i would suggest Flixzone. You can find it on google :)
@Patrick Enzo definitely, I have been using FlixZone for years myself =)
@Patrick Enzo Thanks, signed up and it seems like a nice service :) I appreciate it!!
I am glad you're back Tom I enjoy all your videos I have learned a lot
Thanks Bill
I've been wondering about you. Glad to hear about your new plans. I fully support quick tips, as I'm usually only able to watch long format stuff while multitasking, so then I don't pick up as much. :)
Thanks Joe. Multitasking is my life as well.
Tom
Glad your back and doing well.Thanks for making good videos.
Thanks for watching
Never seen that idea used, been in engineering 50yrs! , just shows that when an engineer, you're always learning!
A good engineer is one who understands there will always something new to learn.
HolEE sheep ship...I tried this and the part came un-cunted, flew out the chuck and blasted thru the windshield of my minivan...WTF just happened is what I thought?
You drive a minivan?
Hello Tom, Great to see you again buddy, and love the new format! Great tool tip, I use my skateboard wheel bearing version, (not as pretty as yours) all the time and it works like a charm!
Best Regards,
Ray
Thanks!
Thank you Tom!!! Very great idea for a quick project.
Thanks Rolando. I don't use it a lot, but when I do, it's pretty handy.
Tom
As I was told by a very smart teacher, It is not the quantity, but the quality that is important. Tips from you will be well received. Do what ya can at your pace. Thanks for sharing your knowledge. Regards, greg
Thanks Greg. When I was teaching, it was 1/4 theory, 3/4 practical experience.
Tom
Unless there's an order for milions of small parts
Another Tom video!!! Thanks for the knowledge Tom. It's always appreciated.
Thanks Aaron
You and this old tony are at the top of my list. Glad to see a new video- thank you
Tony is a good guy.
Great to see you back on RUclips Tom. How tight do you have the part in the chuck when you employ this technique?
Just enough to hold the part in place, then tighten it down after it is aligned.
Tom
Awesome Tip Tom, glad to see you back!
Thanks for watching
Very Glad to see you back! Whatever suits you... Keep the info coming...
Thank you
Hello sir, nice to see you again. Thought about you often sharpening a tool bit or using my fly cutter. Short tips and tricks? 👍👍👍
Sharpening a bit for a fly cutter is on my list of topics, so you'll see it soon.
Tom
nice to see you back Tom. I have been having the same problem getting videos out ;) .
Thanks, it's good to be back.
I hope to retire later this year. That should take care of the time issue. :)
Tom
Don't forget to retighten the chuck and run an indicator across it to recheck.
You could bore some soft jaws.
Made one, they work well!
Beyond helpful and more than effective! Thanks a ton!
Say tom you wanna make me one of those bearing gadgets.. I don't have time to make one at work and be happy to pay 20bucks or so. Anyhow thanks for the tip
You need to get your priorities straight ! Our videos need to be your number one job! Imagine the world without machining ! Haaaaa
Welcome back, we'll be happy to watch whatever you have time to put together for us.
Thanks Tom
Well that's just plain genius! Did you just chuck the piece up super lightly, or was it pretty snug?
This is amazing. Why has this eluded me for this long ? Thank you 🙏🏼
Thanks Tom, I always enjoy you lessons, you are a great inspiration!
Gene
Thanks Gene
What a time saver and I'm glad your back Tom!.
Thanks Michael
This only works if the part is clean from the start and not bumpy like a brake disc might be, still gets close tho, I use this method often
@@hrdu It will work on rough surfaces as well, but the result won't be as precise. It basically averages out the irregularities.
Glad to have you back, even though it means that sweet lathe will not be on Craigslist any time soon (jealous). : )
Sorry Steve, but I'm taking this one with me (When I move North of course). :)
Tom
Toms Techniques I don't blame you. Once again, glad to see you back.
Hi Tom, I used this tip this morning and it worked so well - thanks for sharing.
Great video very useful thank you brother 👍🏻👌🏻🤯
Tom's back! Welcome back! :D
Thanks
I have been doing this for years now, but I just use a piece of plastic that is always in one of the tool holders.
great tip, now I'm wondering why i never thought of it, I've been tapping motor endshields and the likes, true alot this is gonna save me alot of time😀
just want to say that I've learnt alot from your videos, of all the youtube machinists i find your approach to be the most practical and common sense. anything you do find the time to upload is appreciated
Thanks Ben
great...I do parts like this all the time, very useful.....question.....do you tighten up the jaws after? DO you only partially tighten, then align then tighten? How about radial centering.....I guess 4 jaw and slow with an indicator? Do you find a six jaw particularly good for radial centering? Or is it adjustable? As we all know...getting it true is everything! :)
The jaws do get tightened lightly at first, then firmly after aligning the part.
Radial alignment is done by hand with an indicator.
Six jaws are excellent for gripping a part true, and easy on thin wall parts. Only problem is the expense.
Thanks for watching.
Tom
Good tip, seems to work great. I'm going to make one of those.
We called it a put on tool hence one can use it to move metal to one edge or another if one goes under or over size and many other uses ! Thank You thumbs up !
Tom how how tight was the chuck in order for the piece to true up thanks in advance 👍🏻
welcome back sir! looking forward to learn from you!!
Thank you Ian
Great to see you back. Any info that you can pass onto us is greatly appreciated. Always ready to learn something new.
Thanks Tom
Glad to see you back Tom. I use your website and videos frequently and am referring them to others all the time. Any way you can share your knowledge and experience is appreciated. I have an AML-618 lathe at the shop, which is a knock off of your Hardinge. I want to build an indicator holder like what came with the Hardinge lathes. Any tips or photos would be appreciated.
I'm making a note, Bill (literally) to measure up the bracket. Send me your email address through my website.
Tom
You're one of the first content creators I actually subscribed to, mainly because I could tell that you'd be a fount of good machining information for me down the road!
Wow, I made #1? :)
Thanks for watching.
Tom
Very nice pleased to see You back
Thanks John.
Wow! you're back :) awesome seeing you again, Tom. How have ya been?
Thanks for the video -- looking forward for more, kind sir :)
Doing well and thanks for watching.
Tom
Great tip! Thank you! Now I just a tutorial on how to make one!
Glad you are back! Quality videos take a ton of time to make.
I hope this new format is something you enjoy. Chris
I'll pick up the tutorials again once I retire, but for now, this will be the new format.
Thanks for watching,
Tom
Good info.
I didn't even know for this technique.
Nice project idea. Thanks for sharing and glad to see you're back. I like the format too.
I think I'm going to like it as well, Larry.
Thanks for watching.
Tom
You can also use the same tool as an external burnishing tool
nice tip... thanks for sharing your wealth of knowledge in Machining to us novice
Thank you for watching
Welcome back.
Thanks Rick
Appreciate your videos, but family, personal, and livelihood have priority.
Yes they do. I spent last weekend snowmobiling with my sons and it was memorable. :)
Tom
Glad you're back. I have missed your videos, thanks for sharing.
Thanks for watching
As others have said - great to see you back. Personally I much prefer the shorter vids, so welcome your decision very much. Regards, Alasdair
Thanks
Tom
Is that Alfred E Neuman, of MAD fame, looking over your left shoulder from the filing cabinet ?
Good to see you back.
MY HERO. :)
Hey Tom, glad you're back. So on the trueing vid, do we leave the chuck only slightly tight and after bumping it into true then tighten the chuck for the additional machining?
I usually start out with the chuck pretty tight to avoid having to re-tighten it, but it kind of depends on the part. If you have to start with a lighter grip and then re-tighten to get it true, just bump it again afterward to be sure the part is still running true.
I will watch any and vids you decide to make Tom ! I sure need to make this pusher tool man..
Thanks Shawn
Yeah, Tom's back! I don't know why this took 7 days to pop up in my feed. I followed some other youtubers advice and unsubscribed then resubscribed and enabled notifications so hopefully that does the trick.
The YT people don't know when to leave good enough alone and are constantly changing things. I'm still struggling with the comment changes. Hope you get it all straightened out.
Tom
Tom - how tight should the part be in the chuck ? You wouldn't like to tighten it up completely, would you? On the other hand you wouldn't mount the part too loose, right?
It's best to not re-tighten the jaws after the part is aligned. You develop a feel for how tight the chuck needs to be through experience. If it takes you a couple of tightening and aligning steps to get it right, that's ok. Most people over tighten chuck jaws anyway.
I have a classic car I am rebuilding. I am working on the differential. I obtained a ring gear and pinion. Comparing the old pinion to the new one, the old one has about 6 thousandths thicker where the outside bearing rests. Looking at the thermal expansion from Timken, then bearing mfg, I can see I cannot expand it that large. So I ill need to turn the spline end down a little bit. I have a couple of questions. 1. how to get it trued up. One end is a gear, and the other is threads. I know I cannot chuck down on the gear. How to chuck down on the gear? How to true it up? Do you have any suggestions?
The pinion likely has center drilled holes in each end that you can use to support it between centers and drive it with a dog. The next problem will be actually turning it, because it is probably hardened. Carbide tooling will be a must.
Glad you are back! Any knowledge you want to share is great.
Thanks Mike
You might have been getting a cosign error with your indicator the way it was rested on the part , normally you should be sitting about 17 degrees with the surface . I actually made one if these and it works wonderful
Cosine error only comes into play if you are taking a direct measurement. In this case I am only looking for run out, or lack of.
Tom
Thanks Tom! Superb lathe you got there. I have a Hardinge Chucker that I'm in the middle of setting up in my garage.
Thanks.
Hope you have lots of tooling for that chucker, because it doesn't come cheap.
Tom
Short or long...I will be watching...great to see a vid from you...ATB
Thanks Chuck
I've seen a similar technique used before but I can't for the life of me remember if it was a machinist or a woodturner who was doing it. I think it must have been a woodturner straightening out a long piece in a chuck, either just by hand or with the handle of a tool or something.
I haven't seen it used outside of machining, but it wouldn't surprise me if it was.
Thanks for watching.
Tom
Nice little Video Tom. Any info is better than no info. ant time you can here from an expert its Good. Thanks for doing these.
You are welcome Garry.
Fantastic Tom.....Thank You so much
Great idea I am going to make one thanks mate
hi Tom just wondering do you ever have to worry about nose radius compensation on a manual lathe. if you do how?
Nose radius compensation is only a concern when turning contours, i.e. feeding the X and Z axis at the same time, which is not something that can be done on a manual lathe, at least not by me. :)
Tom
Have you done this on the OD also combined with an indicator close to the jaws.
It would probably work on the OD of a shaft extending from a chuck, but probably not as well due to springback of the shaft. Try it.
Tired of these people dragging this on and on, please get to the point, your vidoe's are great apart from my complaint.
Your complaint is unwarranted. This is the shortest video I have ever made, all of five minutes fourteen seconds long. Considering the average length of a RUclips video is four minutes twenty seconds, I guess I did "ramble on and on" for fifty seconds, explaining about how I plan to start making shorter videos, but I guess you must have missed that part.
I was wondering about you ! Glad your back.
Good to be back, Danny.
Any round nose tool with the chuck running backwards does a similar trick .
This won't mark the part.
Tom
Reducing the length could easily be done by deleting the preamble and just get to the point.
Lol. You must not watch many RUclips videos if you think I talk too much.
We missed you a lot. Glad to see you back. Anything you want to do is fine with me.
Thanks Bill
good to see you back Tom...keep them coming
Sounds like a plan
Great, very useful tip.
Thanks for the video , glad to see you back .
Thanks for watching, John.
Thanks Tom I hope all is well
even better is to make one with two ball bearings so you can use it in both sides of your tool post. their are a couple of examples on the tube.
cheers
Teun
The possibilities are endless.
Very slick!
Thanks for watching
You got a new subscriber with this little tip good stuff keep it up I might learn a thing or two.
It's never too late to learn a thing or two. :)
Very cool Tom. How accurate does the spinning bearing need to be?
I suspect any bearing would be precise enough to align a part in the lathe. The one I used was just something I had in hand.
Tom
Terrific video, Tom. Another tool to add to my build list.
Thanks Kevin
The quick alignment bearing is an elegant solution.
However I think I noticed an insert in the tool post to allow a wider tool holder. Not sure if that was what I saw, but if so how well does that work? Can I go from AXA to a BXA holder?
Not sure what you were seeing, but an AXA post will only accept AXA tool holders.
Thanks for watching.
I now see it is just the cam-lock of your tool post. My tool post holder cam is not visible. I thought it might be a dovetail wedge to allow use of a larger holder. But I see the holder is already an AXA model.
I have a 1" parting tool holder that's a size too large and was trying to figure out a way to use it other than welding some fill on one side and then machining it to AXA. Probably a silly idea and being too cheap - sorry to waste your time!
Great tip, thanks for your effort.
Thanks David
Good work Tom!
Thanks Alan
Thanks Tom. I like this format. Are there going to be any more?
Eventually. My wife and I moved, and I'm out of business until yi can build a new shop. It's coming along, but there is a long way to go.
Please do more of these!
Thanks Tom for the tip. I've never seen it before and love it's simplicity.
