The Home Machinist!

Hah. I had the 3 sided experience just last week. I have a 1958 Atlas 3 jaw that has been used hard. I chucked up a piece of 1/8 dia brazing rod to make a 1/16 dia pin. Floppity-flop, 3 sides. I ended up making it from a piece of 1/4 dia brass. Right on, gentlemen.

This is the type of hobby vise I have made for holding small parts. Both are made from 1018 plate, or whatever I had. The larger one is 1 x 2 x 5, The smaller is 3/4 x 1 x 3, but they can be made any size that suits your purpose. Clamping flanges or threaded holes or whatever can be added to hold th...

My lamp holder is a section of 3/4" LocLine coolant hose. It works really well and is easily adjusted. A similar one is on the Delta T&C grinder.

Glen, While you have the sear all lined up and rotating concentrically around the hole, may I suggest a modification that helps get a smooth unvarying trigger pull? The following is a pic of the unmodified sear, but to make a smooth trigger pull one should grind away the area cross hatched in green ...

Years ago at the Colorado School of Trades where we had South Bend Lathes, we were taught to thread up to a shoulder, i.e. think of a barrel stub against a receiver, by disengaging the drive with the tool still in the cut, and then turn the chuck by hand until the tool was against the shoulder. Tool...

The instruction book for my 1958 ATLAS lathe lists 79 imperial threads and 16 metric threads it will cut. It specifically says that when cutting metric threads, DO NOT disengage the half nuts. I have a box full of change gears instead of a QC box, in case you wondered.

And here is a model of it that my VERY talented friend made a few years ago. It is one of the many supreme models that he has made of odd things. Mr. Wheeler gave me permission to post this photo.
