Phil, You might try making the 3 stand offs intregal with the back plate instead of the collet holder section.


Thanks for the vote.

Thanks John, yes the collets should be big improvement instead of making a one off mandrell or something.

Thank too Bob, I really had no idea it would make POM.

nice job,the chuck came out very well with a nice finish.
what type of metal was it and what was your source and cost?
here local there is only one place for metal and its hot rolled. it does not machine well almost gummy. but when i check for metal online the prices are too high for me or i'm looking for the wrong thing. what should i be looking for that machines well at a fair price

Thanks Steve. It's all scrap metal from our local scrapper. I have no idea what kind of steel it is. The nose piece was a roller of some kind I picked up years ago. I used a HSS cutting tool to mark it by hand to see if it would be machinable. The rest is just some rusty flat plate I found at the scrapper. The back plate is cast iron. I know the steel got hard when I welded it so it's not regular mild steel. I had previously built up some mild steel for a conneting rod on my loco by welding and it didn't get hard like this. It machined very well.
After I welded on the stand offs for the chuck it was hard machining even for my cheap carbide cutters, the HSS wouldn't touch it.

As far as cost I may have $30 to $40 in it and $10 of that is for various 1/4- 20 cap screws.

The finish was accomplished by filing and 150 and 250 grit emery cloth. The final finish using well used 250 cloth truning at 1200 rpm in the lathe.

You've inspired me to start on an ER32 collet chuck.
Less complex than the 5c, but it'll be the first time I've tried to bore an internal taper, (I'll probably be asking questions about doing that soon ;) ).

I don't have any of the blue stuff to check fits so I used a Jumbo permanent Black Marker. Painted up the taper part of the collet and put it in, gave a little twist.

It showed contact from the front of the collet back about half way to the end of the taper. Adjusted compound took a light cut, put on more marker, and it showed contact full depth so called it good.

You'll do fine.
