Default More mini lathe issues

My screw / pin is complete. Took some doing since I don't have any of the
right tooling for this.

I do not have an center drills either so I center marked it with a 1/64 ball
mill in the drill chuck, and used that hole for my live center.

Cranking the speed up to max helped a lot. I used a very narrow cutter to
rough to size, and then a wider cutter at .001 per pass for the last .003.
The gave me my pin shaft diameter. Then I had to cut a little smaller to
make an extended shaft for a nut. The original was just pressed and peaned
over. I cut mine to press in and then have a nut threaded on. I cut a
shoulder and then extended shaft was threaded to 10x32. Didn't do that with
the lathe though. I just don't have a tool bit I felt comfortable doing
that with. Instead I used a die, and then reversed the die for the last 2
thread up to the shoulder. Sadly I got some marks on the head in the vice
even clamping the pin between two blocks of wood.

NOT GONNA POST A PICTURE. As a shoulder screw sitting on the desk it looks
pretty good, but when I snapped a picture I could see all the imperfections.
LOL.

Definitely want to get some other bits before I tackle something this small
again.


Bob....what is the maximum size tool bit your lathe can use? The
"normal" size?

Ive got a fair amount of HSS kicking around and Id not mind grinding you
up a couple sets of tools and sending em off to you to play with.
Right,left, groove, cutoff and threading types ok?

send your shipping address to and Ill get
something out to you by next weekend

"I am for doing good to the poor, but I differ in opinion of the
means. I think the best way of doing good to the poor, is not
making them easy in poverty, but leading or driving them out of
it. In my youth I travelled much, and I observed in different
countries, that the more public provisions were made for the
poor the less they provided for themselves, and of course became
poorer. And, on the contrary, the less was done for them, the
more they did for themselves, and became richer." -- Benjamin
