Hi Jim Great find with all those collets, i'm a little jealous there!!!!. If at first you don't succeed try try and try again!!!! I'm accomplished at that proverb!!! Just a thought, which i'm sure you have thought of, is, could the collet adapter you made be okay and the run out is in you Unimat spindle!!! nose!!! Anyway something to keep those grey cells exercised!!! take Care Kev
Hi James, nice to be here thank you for sharing your channel with us, collets they are one of the hidden expenses of micro and watchmaker lathes, something we are thankful to have solved in our own shop looking at the prices these days we would have had a real challenge achieving this task for our own shop for sure. Nice to be here with you, thank you for sharing. Lance & Patrick. Question James if we may? How was the spindle runout in the headstock before you made the adapter and its extension from the original spindle edge?
Thanks Jim. With that distance you would have to be perfect or grind it in is my guess. My purchased MT 4.5 spindle adapter (alleged precision ground) is far worse than what you made. LOL.
My unimat 3jaw Chuck has a 0.05mm runout and still sufficient for the job. Maybe unimat is just not designed to precision work like the watch maker lathe. Maybe worth making a back plate so you can micro adjust it by tapping the back plate with a hammer.
Not a fail it just needs a tweaking. 7 thou not horrible some chineaseum is over 10 thou lol. Keep up great work sir. Stay safe from ur ole hillbilly buddy. PS. If u don’t want that one I would love to have it. Put with my db/200.
Interested with what might have happened here. I'm with Facto on this as my first thought was have you indicated the spindle cartridge? Bearings could be going....keep moving tho!
I don't think I spent enough time indicating the collet holder in when I switched the machining from the unimat to the "big" lathe. I am going to pull the spindle from one of my other unimats and hold that in a collet on the big lathe to do as much as I can in one setup.
At some point in the near future I will be revisiting this collet adapter idea for the Unimat, I will More than likely be showing more of the machining operations on my next attempt. (I am still learning the intricacies of filming while machining) Thanks!
@@Jims-Workshop Looking forward to it Jim, nobody expects you to be perfect. If you go back in time and watch videos of other successfull channels in their early days then you will learn soon enough that a far from perfect video still can lead to a very successfuill channel. Good luck with it!
Hello. Jim. I was wondering why couldn’t one use these er16 collet holder’s that have Morse taper (taper wouldn’t matter ). And uses m12 x1 draw bar. Cut the taper off and face it true and it should thread on. M12x1 threads. I haven’t done very much machinist work done welding and fabrication automotive work. Just wondering if u knew. There lot cheaper than unimat ones few hundred dollars. Thanks from ur ole hillbilly buddy stay safe
Hey Jim, I've been pondering this video. I'm just wondering if you used the indicator on each step of the adaptor not just the rod? Just wondering. Thanks for the video.
James, I need to do a follow up video on this. I need to use the indicator on the spindle directly on all 4 of my Unimats to see what the run out is. Then I am going to make a new collet nose
@@Jims-Workshop right on. I was thinking indicate the spindle and each step of the adaptor , sounds like your already in that line of thought. I'm curious too much. sometimes I get my mind on something and it won't turn off.🤣

Hello Jim,
Interesting video... pleased to hear you are still pushing ahead with the project... See you on the next one...
Take care.
Paul,,
Paul, Good thing about making projects like this is you can keep trying until you get it right.😁
As soon as I saw this post about the Unimat I thought, I wonder if Paul has seen this video. Yup, you did 👍
Call it a learning experience. I'm following you in this endeavor with great interest. .👍
Thanks for following along JamesP
Hi Jim
Great find with all those collets, i'm a little jealous there!!!!.

I have not checked runout on the Unimat spindle. I'll have to do that.
Snooping around your youtube channel😁
Hi Jim, Finely made it to your channel, sorry it took so long..hitting sub.. Nice find on those collets!
ATB....Dean
Thanks for the sub!

Thank you for Subscribing. I will do a follow up video where I check the runout of the spindles on all 4 of my Unimats. I have never done that.
Hi Jim. Sorry to see that the adapter your made wasn't running true. I hope you sort it out mate. Cheers, Aaron.
Jim, this is a very helpful video. Were you able to identify the source of the runout?
Thanks Jim.

A general question that I hope to answer: Does this lathe have the ability to cut Iron or copper and aluminum
Not a fail it just needs a tweaking. 7 thou not horrible some chineaseum is over 10 thou lol.

I bought inexpensive collets from amazon with that much runout in them, returned them and paid the price for decent ones.
WOULD HAVE LOVED IT SEEING YOU MAKE THESE!

That’s what I been thinking. Get one and tap it. One for motor shaft. Idk. Not a machinist was welder/fabricator.
I like collection this collet,how many rupiahs these price
Love the video’s.
Thanks Paul 👍
