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:

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

You can rest a bit better knowing that at the end of the day you will have all of your knuckles!

Wow!
THIS is the type of thing I love. It might have seemed a little scary to some, but you knew you could do it and you did it, bang!
It's amazing how much is perception and "clicking".
Fine work, thanks for the inspiration.
