Testing out my New Revolving Tailstock Chuck - Manual Machinist - Turning Big Trunnion Wheels 

Another good video Josh. Back in the day (before I retired) I worked on a lathe which had a 4 jaw tailstock chuck. This made it a whole lot easier to set up (accurately). Keep the video's coming Josh, I appreciate the effort that goes into making a video and enjoy watching your work. Thanks.

Nice to see another one of my brethren that uses Coçk$úçkèr as an exclamation of anger or frustration in the wild. 😂 I use it all the time and idk how many times I've had ppl think I was calling them one when I said it. Then I have to explain that I use it the way others use SOB, God Dammit or Shite. 😆 Great video Josh 👍👍

I would just make jaws for the rotating chuck, then you can do as needed.

Great post! I learned first about the tailstock chuck in CEE Australia. I was able to make one 3-jaw and also a 4-jaw for my smaller lathe. A must working on tube/pipes and very useful for messed up centers like in your great example.

Noticed you tightened the 3 jaw & then added the tailstock chuck. I've found on mine, that if you loosened the 3 jaw after tightening the tailstock, runout improves. Sometimes even loosening the tail after second tightening of your main, improves it even more. May not work on yours, but give it a try.

First tailstock chuck I saw was on Cutting Edge Engineering's channel. He uses his a lot as I am sure you will too. Good choice.

I like the revolving tailstock chuck, I did not know such things existed

If you are going to make another chuck it would be handy to have a 4 jaw one another good video having the reverse speed faster is very deferent

Watching numerous manual machining channel videos including your makes me wish I had started a career in machining rather than electronics in 1974 in the Army. My choice to go into electronics lead to a 29.5 year in electronics, Instrumentation & Controls including pneumatics and hydraulics becoming a senior technical engineer for most of those years) before my entire adult life in chronic pain and sleep deprivation took me out of work at 51, I’m 66 now. For me there has just always been something about mechanical challenges and building/repairing/reworking items that gave me a far greater since of accomplishment. Envious of your career and shop for sure. Stay careful and thanks for the videos.

I have in the past added a VFD to a 3 phase machines to get a desired RPM not available with the gear selectors. Simple but effective solution.

You'll love that tail-stock chuck the next time you have a larger hydraulic cylinder to machine. Very practical addition to the lathe. Thanks for another interesting video.

Your videos have become as good as A-bomb's. Good work. Much appreciated

The 3 jaw rotating Chuck on the Tailstock is an excellent addition to your shop. You set up your Lathe before starting it,to prevent any possible crashes is good practice for any machine or home machine shop. As always great video.

I've been watching you clean up these trunnion wheels through a few videos, some with the Monarch, finally an explanation of why you were using a long boring bar rather than a tool in the toolpost!

What is funny is that you have just shown me a trick that will work quite well for me on my tiny Chinese junk 7x14 mini lathe to allow me to turn parts at about the 6 inch diameter. I like the inverted boring bar trick. You have some interesting equipment, the shaper and the Radial Arm Drill Press are fun bits of kit.

I've thought about buying one of these a number of times. I have a couple chucks with backplates I made that have center holes that I use all the time. Just clamp it to the part and then use it as if it's a center in the shaft. Works well for large tubes that have too crooked of a saw cut to use a bullnose center on too.

G’day mate. Looked like a relatively easy job for a change. Thanks for the video. Have a good one 👍🇦🇺

I'm changing your name JT to The Master of Innovation. Tailstock chuck, gigantic boring bar upside down, lathe running in reverse all great tricks of the trade. Enjoyable video thanks and have a Merry Christmas.

A very useful addition to your lathe for when you can't use a live center when the drilled center is damaged.

😃😃😃😃It is always good to see you. I am glad that you found a tool to help you work safer and better.

Great video Josh, build you a four jaw next you'll like it, helps fine tune the job's, keep'um coming..

I actually built one with a 4 jaw so I could true it up.

I thought I was watching Curtis at CEE there for a second! 🤣 Great job! recently found the channel and I enjoy it. Thank you!

I got a revolving tailstock but a 4 jaw and it helps me to center it much better.

Thanks for sharing. Wow, that looks handy.

Nice lathe.

hollyyyy shit that huge boring bar is amazing

Nice. I need (want) one of those. Will have to make one. Cheers!

there are all kinds of tool head configurations for that boring bar set up. grooving, threading, triangular square, and diamond inserts. that will be the handiest set up you have in your shop when you get it supplied. another good idea is to run a coolant hole from the end of the bar to the tool end where it shoots upon the tool as it works. pipe tap the end and put a snap coupling end on it. that way you can run either coolant or forced air to the tool

I love that lathe and any new tooling you get or make for it I look forward to seeing. Especially if you make a larger live tailstock chuck.

the bearings on that tailstock are deliciously smooth there is something extremely satisfying about watching you set everything up on such a large machine and have it all slide together just so with no slop 5 thou run out when its being pushed around by hand is not a lot but when its running and cutting that translates in to quite a lot of vibration ...not good for your lathe bearings even if it doesnt matter for the part....I would still use the tailstock chuck.. Thanks for sharing

I made a 4 jaw using the Bison MT4 adapter, just had to make a intermediate plate to account for hole patterns.

Rap the spinal with aluminum flashing like they put under your shingles on a house big box stores has it in a roll about 6 inches wide. It works great and won't scar very precision parts of shafts I believe that will take up the space in your revolving tail stop center.

Nicely done Josh, always enjoy catching up with your workflow buddy, Happy holidays to you and yours and here's to a wonderful new year

Great job - thanks for sharing

Good stuff.

I LIKED IT, GOOD JOB.THANKS FOR SHARING.

Merry Christmas and a Happy New Year to you and yours. Thank you for your interesting and informative video's.

good idea 👍

another good video. Many thanks for the time you put into your You Tube presentations, I appreciate what you do and have learnt a lot. Wishing you and family a very Happy Christmas

Josh, I have a factory made 5 inch chuck like yours, I have found it many times to be too small so I built an 8 inch, I just bought an inexpensive three jaw chuck and built the rest, found them to be one of the handiest additions to a tail stock.

The fact that the chuck is already pretty steady, and the fact that you only make light cuts probably negates any benefits, but if anything, it looks a lot cooler being supported on both ends.

6:23 😂

really appreciate you calling it a revolving center & not a live center...its a pet peeve of mine. great work on the tail stock, that seems super handy!

love that tail-stock chuck. Is there away of adjust it to calibrate Its centre ?

Just looking, Josh, you probably didn't need to change the jaws around on the new tailstock chuck for the reason that gripping the job on the inside of the inner jaw in the reverse position leaves you with the same length of scroll as you would have had if you had used the jaws the normal way. Just sayin’. Keep up the good work!

Except for the wear areas mainly the ways on metal cutting lathes manufactured during the WW2 era. Were way overbuilt and with proper care will last many generations. These wear areas (the ways and carriage) can be repaired with Turcite and then scraped. As far as I know and don’t understand why especially on commercial lathes. The ways aren’t replaceable. The only lathe that know of,that has replaceable ways. Is Brain Blocks HUGE Monarch Lathe. I do know that certain lathes have a precision removable bed with ways near the headstock for using larger stock than the lathes normal diameter capacity. I’m not a machinist and going by many of the Machinist RU-vid Channels videos. I have an excellent memory and a lot of common sense. I believe that by watching the many videos produced by machinists over the last 10 years.That I could get by with operating many manual metal cutting machines. Of course SAFETY is of the most importance. Please excuse the extra long comment. I am caught up with everything to do with my home and yard. I’m 67 and don’t like sitting around and doing nothing. Im extremely BORED. So It’s a binge watch machinist videos day.

Hi Josh, new viewer here. Sure like your new lathe, I'll be you enjoy it too ! I have a job to do on something similar, but on one end of the stub shaft. I have an older 26" Monarch lathe. Rock crushing conveyor drum has BADLY worn out 2.5" diameter bearing area. It is on the same side as the big flywheel goes on, with a key way on that self same side. I MUST get the 2 diameters absolutely in line, as the bearing goes on first, then the big flywheel goes on last. Liked your new 3 jaw chuck to go on / in the tailstock, but to get both OD's absolutely in line, I take it a 4 jaw chuck would bring it as close as possible ? I too have an all manual machine shop in N.Eastern CA. Cheers and thanks Mate.

Great addition to the shop Josh, could it be modified to allow the jaws to fully close? No defects in these trommels, I was impressed with you using an UT thickness gauge on those. Great job and photography, thanks for sharing.

Nice boring bar. Is that a solid carbide bar?

You need to get a Spray welding system, then you could extend the life of those parts. Build it up then machine it back to original specs!

Noticed that you are working off the bare concrete floor we always used wood mat in front of all the machine tools. Fireball tool did a good video on a wood mat build for his shop. Take it under consideration your feet, legs and back will thank you when you are older. After 30+ years as a Machinist i still prefer the wood mats over the rubber mats more room under the mat for chip build up and cheaper not that i have had to buy them from my wallet.

They'd make good flat belt pulleys....Dave

Good 🇬🇧☹

I think im going to buy one of the revolving tail stock what seller did you use?

Your tool post looks like a standard one, so I was wondering why you loosen the nut on the tool post rather than use the handle? It doesn't tighten well?

Would your clearance issues be helped by having your top slide parallel to lathe axis?

Curious what the wheels are from?

At 13:35 it looks like there is a gap between the jaws and the shaft. Is it clamping on the master jaws?

My question is about the "trunnion wheels". I know for that application you machine them flat. I worked in a Vermont factory that had overhead belt drive system that had the belt dropping down to each machine. These pulleys were just like what you are machining except that they had they were crowned to keep the belt running in the center. Would it be possible to machine a crowned pulley today?

Do you have the link to seller for the live chuck? I’ve been looking for one but they don’t look like they have the quality of the one you have. Thanks

Whath do you think about the old monarch manual lathe?? They are so good that they say??

I JUST WATCHED YOUR VIDEO PAGE ~ AND CLICKED THE THUMBS UP...AS ALWAYS... I HAVE AS OF LATE BEEN GOING BACK TO A NUMBER OF VIDEOS I HAVE WATCHED AND FIND MANY OF THEM ARE THUMBS DOWN... THIS IS A FACT...IS U-TUBE CUTTING YOUR COUNT(S) Y / N ? ~

If you're going to the trouble of making one you might want to think about a 4 jaw

Will you share the link for the rotating tailstock chuck? What MT is on your lathe?

Interesting; one puzzle though All the 3 jaw chucks I have seen I guess scroll chucks. Obviously have separate sets of inside and outside jaws. Yet you reversed these jaws is there a three jaw chuck type I haven't seen?

Do you have a eBay link for the revolving chuck? Thanks.

was clean up on the journals not needed? They looked a tad rough

which lathe was more ridged. the monarch or the lion?

A while back you re-turned another trunnion wheel and your speed was faster. You got a lot of chatter and slowed it down like you are doing now. I'm wondering if you can increase your speed now that you have tail stock support and not get chatter? I don't know if anyone else said anything about tail stock support, but I asked about it.

Live Tailstock Chuck?

Do you think a 4 jaw tailstock chuck would be better than a self centreing chuck, so you can adjust the run out.

Did yur Revolving Tailstock Chuck come from the US or overseas...what is the model number pls & thank ya 🖐😎

I hope this isn’t to personal or anything. How much do you charge for a job like this? I’m only asking this out of pure curiosity.

Merci !

Can't hear anything you said while the lathe was running.

man I wish you would put some wood on the ways of that lathe

Josh, is it necessary to tighten so much your tool post? God Bless. WWG1WGA

Josh we cant hear you much over that screaming loud cut. Still like seeing the work though.

Couldn't understand what you were saying. But that was a good thing.

4 jaw would be worlds better
