🔥 Making a Lathe Chuck Back Plate

[@mhc6777]

Thanks for sharing - I've been put off by the tight tolerances needed for a back plate as well, but you have given me some ideas on how to tackle it.

4140, such a great material to machine. Nice work! Cheers for Chicago.

So true. With the right speeds and feeds a nice shiny finish can be achieved.

Hi Nice Vid, backplate turned out tops. I just purchased a 5"/125mm Bison self centering 4 jaw myself. I already had a chinese independant 4 jaw, but couldn't refuse this one at AU$300.00. Now to make a backplate. Not sure what to use this time, last one I made was from a 2.5kg cast iron barbell weight, messy but turned out good, only cost AU$2.00. I might just use steel this time as I have some scrap, much quicker than cleaning up the barbell weight. I am running an old Taiwanese copy of an Emco Compact 8. Cheers Peter

300 AUD is a good price for a Bison chuck. I hate working with cast iron due to the clean up and the grit is quite abrasive if it gets on the ways but it sure machines nice and easy. Steel makes a fine back plate. Good luck with it!

[@petermurphy3354]

@@ProjectsDownUnder Yeah cast iron is really too messy, I think I will go with steel for now. I have a bit of a chuck fetish at the moment LoL. On Facebook Marketplace there is 110mm Lathe chuck. Union Mfg, Removable soft jaws. Made in Britain for AU$150.00 mint condition, but they are in Sunshine VIC, & I am in Belgrave VIC. opposite side of Melbourne, too far at the moment😢 Where in Oz are you?

[@ProjectsDownUnder]

Never heard of Union Mfg chucks but if its made in Britain it's probably better than a Chinese chuck. I have gotten away without using soft jaws by just using some copper on the jaws to protect the part. Thankfully I am in NSW but I can see by what's happening in VIC that it can change rapidly :(. Anyway stay safe Peter.

That's a very fine machine you got there. Unfortunately for me it cost an arm and a leg.

[@jimsvideos7201]

I noticed your mill spindle running out when you were putting in the counterbores. It doesn't matter here with the chuck registering on the shoulder but if you want to avoid that perhaps drilling as much as you can with a twist drill first and the mill cutter after could help.

[@ProjectsDownUnder]

Thanks for the tip.

If you can’t produce a simple back plate without cnc you should not be operating a lathe

[@WekaWindows]

if you can't produce a simple nice thing to say - you should shut the fuck up.
