lathe collet chuck

Hi all
After finishing my beam engine I wanted something easy to do whilst thinking up a new project.
I had to turn a small piece of square bar and not being able to hold it in the 3 jaw and the 4 jaw wouldn'd close down far enough I used  my collet chuck from the mill .

the trouble with that is it will only take short pieces.
I looked around the net and found various places selling mandrel mounted collet chucks, my lathe has a flange on the spindle so chucks bolt on, but the cheapest was about £35 odd.

so I thought "I can do that".
the hardest part is the closing ring and I already have one of those so








the body is screwed into the backplate using the same thread as the cap.
my first piece of internal threading.

I put a length of ordinary bms rod in it and clocked a total runout of a quarter of a thou.

total cost £ 12 and probably as much in weight of swarf  :lol:

cheers
Roy

Add my kudos. Simple, elegant, effective.

wheeltapper:
Thanks guys.
It also feels a lot safer having my hand near when it's whizzing around at 1000 rpm, no sticky out bits.

cheers
Roy

"That`s the way to do it!"  :clap:
