Re: 3 jaw chuck

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.

Re: Material for Small Vise

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...

Re: Lamp Stand.

My lamp holder is a section of 3/4" LocLine coolant hose. It works really well and is easily adjusted.

Re: Grinder Wheel Adapters

Thanks for the confirmation, Harold.
This was also confirmed by a utube video https://youtu.be/N9_7XvLFcNM by some German fellow named Stephan Gotteswinter which I saw after posting the question.

Grinder Wheel Adapters

Some GWA have RH threads and others have LH threads. I always assumed that one was supposed to use the adapter that had nut threads that tightened the opposite way the wheel turned. THEN it was noticed that some GWA have a keyed washer on the nut side of the wheel. Does this mean that it would then ...

Re: Drill or mill?

This is what I found out about Chinese boring bars: Unmodified, they do not present the cutting edge to the inside of a bore in the proper relationship. boring bar unmodified.pdf The modified boring bar presents the cutting edge more closely to radial, and cuts much more efficiently. boring bar modi...

Biax flaker

If any one has a spare Biax half moon flaker, or another brand equivalent to their HM 10 model, a friend is looking for one. Even of you know of someone who might be willing to part with one, please answer here or PM me. TIA

Re: 1911 Project

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 ...

Re: Screwcutting not picking up in the same place

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...

Re: Screwcutting not picking up in the same place

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.

Re: German Mortar

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.
