Re: Dial for Drill Press Speed Control?

That hasn't been my experience. I have a plain old hardware store turn-the-knob dimmer in a box. With an outlet and a power cord. Highly portable. I use it with my routers, tool post grinder, die grinders, Biax scrapers, the lot. While I may not try for the slowest possible speeds (that would be pro...

Re: Electric Motor question

Serious connections are keys and the dimple. The set screw lock screw, which I first saw in a B...

Re: I started an Allen Mogul project

As far as plan sheets go, I have found that most drawings are printed way larger than needed so I reduce them to 8 1/2 x 11. Then they can be easily filed in a binder and used i...

Re: Plating brass over chrome

So. the spec for board edge connections was 20 uin. min. of nickle on the copper, then the gold. Usually there was a thickness given for the gold b...
