I keep getting amazed at the knowledge I gain about these chucks. People with new machines probably won't care as much as I do but my Love is rebuilding these old Iron relics. Thanks for taking the time to teach us.
I will use that roll the piece clockwise while tightening the chuck from now on also I never knew 6 jaw chucks were to be saved for ground stock. Two things I learned today! Thanks, dee
DeeDee, Another channel, Dudley Toolwright did some interesting experiments recently using a piece of precision ground carbide and a test indicator to try and see just what difference it made in how he tightened his chucks. Kind of fun Voodoo results. I’m of the opinion that being able to uncounted/remount chucks, which you do often, may be more for the kind of things I hope to do. It seems that rebuilding chucks will “turn” out to be a lot of fun and make a big difference also. I’m still betting I’ll end up counting on my Pratt Bernard Multisize collet chuck and a good 4J chuck for most of what I do. We’ll see soon. Cheers, TB
The scroll chucks have a little voodoo going for sure because of the needed internal clearance will change the outcome if the chuck is not tightened in a consistent way. Later I will repair my hydraulic workshop press and demonstrate bending and straightening steel, that will reveal an important nature of metal. I have a story- I worked for a Harley dealer nick named Onionhead...Customers would ask him how to rebuild their own motors, and he would them, sell them the special tools at super inflated prices also the parts even give them advice on the phone and us back in the shop would just nearly die laughing. In those situations Onionhead really came out on top, would end up selling them a new bike. You can tell people how to do it, they will 99 out of 100 screw it up.....
Wow, very good video. I'm over here in Kennewick and I have a 8inch chuck off of my Lelond 15X30 Lathe and I bought a new bison. But I would love to see you do a video on machining it out.
The 12" steel Bison that came with my gearhead lathe is the best built chuck of that size I have seen, it just needs the jaws ground. The 8" Cushman on the Monarch has reached a point that the internal wear is too much, but it took me 22yrs to wear it out. I am on a save money kick anyway
Hello. I really appreciate your videos. I would respect your advice in regard to the thickness of concrete in my garage. I have an old 1920 lathe I restored. Im getting a lot of chatter. Assuming I have the tool set correct, and have the spindle bearings and all else nice and tight, could the chatter be caused by not having a good thick foundation? It is a 1500 lb 14 by 40 lathe. I am 45, have run plenty of old machines at work, and have never experienced chatter like this. I am not sure how thick the concrete is, but i doubt it exceeds 3 inches. I can pound my fist on the saddle and shake my whole attached garage in my 1937 house.
I gained some construction experience, but I must rely on my friends at the concrete company for that advice, they do it every day. My experience with old lathes makes me think the rear spindle bearing is too loose, try setting the rear bearing first with the front bearing loose, then set the front bearing. I dont think the problem is the floor. Thanks for tuning in!
ive only had my lathe going on a year an ive always seen these 6 jaw chucks but never really knew what jobs they was meant to be used for. i assumed it was best for pipes cause it could spread its holding force across more area an keep from crushing the pipe but that was just a guess. what are the best situations to use the 6 jaw.
@@stricht8 Jaws sets were available but need grinding in. I have heard some time ago that their newer chucks are different in design and older parts are not available
@@deedeeindustrialsuperprecision oh that stinks! Might have to get a new chuck then or just make do with the 3 jaws in the existing one, assuming they can hold a piece tightly enough.
But Donie, you are demonstrating a chuck that can be set tru or adjust tru depending on which brand you have. Myself I have a Bison 8 inch 6 jaw which I bought brand new to fit my Victor 16x60 lathe. Why a 6 jaw? Because no matter what round stock I put in it I can true it up except for hot rolled in which you have to fuss with. I am not knocking your method by any means and certainly your advice has a lot of merit. Cheers.
@@deedeeindustrialsuperprecision Dee, why are you knocking me for petes sake. I am as old as you are maybe older. I like your content, but if I get another response like that I will have to say bye. I mainly use the adjust true for picking up a concentric known journal and proceed from there. Plus, when machining thin wall tubing the 6 jaw is the choice with exception machinable collet chucks. I gave you a complement at the end and you came back with that response??
She is such a little sweetheart. I smile every time I see her.
That machine has been in continuous service for over 70yrs, Ilike it better than the newer one.
I was talking about Chloe

A new 12" Bison heavy duty standard 3 jaw chuck is very close to $2000!

Try it both ways see if it works with and indicator.
Great info Dee Dee, I learn something ever time I watch your videos, keep'um coming..
More to come!
The rotating while tightening is a great tip! Thanks dee Dee
Give it a try! Thanks!
Wow. Thank you for documenting/preserving your knowledge.
It was preserved with Wild Turkey, but my doctor says no more, thanks.
@@deedeeindustrialsuperprecision I think you earned an upgrade on your embalming fluid. ruclips.net/user/ralfystuff
Excellent video. Thanks!
Glad you liked it!
Thank you very much. Very well explained.
You are welcome!
I’ll have to try that technique out. Thanks again for sharing!
See if it works and try all the pinions.

I have been using 6 jaw chucks for 24 years.
At work we have 8” and 9” Buck chucks on EE’s they work great
I have never seen that. 8" is maximum from the factory using light duty 3 and 4 jaw direct mount.
@@deedeeindustrialsuperprecision these 8” & 9” chucks have been on these Lathes for 30 years.
We do lots of plastic and Aluminum some steel
Great tips!
Thank you!!!!! :)
You are so welcome!

I like to use the chuck on already machined surfaces to reduce marring, thanks!
My new to me 10ee came with a 6 jaw Buck chuck. Guess what, it only has 3 jaws attached! Go figure! A fourth jaw was in the cabinet.
Good morning! That happens a lot. I hope you enjoy your Monarch ee as much as I do mine, thanks for tuning in this AM!
@@deedeeindustrialsuperprecision I wonder if it’s possible to get new jaws to replace the missing ones?

@@markmuranyi9289 Maybe it's because 6 jaw and adjust tru do not go hand in hand.
