Well, it is once again time for me to use an engine lathe to single point
thread. It seems to be something I do every couple years so I've never
realy mastered it.



Maybe buy a friend a beer to do it then and don't bother to learn,
unless you really want to.

Well, the lathe that works is at work. My friends near by don't have
lathes. I'm gonna do it but I figured I'd draw on the wisdom of the group
for any ideas to improve my chances.

The whole point of aquiring the lathe was to be able to build stuff. Screws
are high on the list. As soon as I get it going, I want to make a new cross
feed screw for my bridgeport but that is questions for another time....

Practice on a straight bar to pull out at the same point. The white
mark on the chuck will make it a lot easier to hit the same spot each
time. 45 rpm is more than one second per rev. Ive seen really
experienced lathe ops. run up to a shoulder at a lot faster rpm than that.
