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

If the motor has brushes, you can run it through a light dimmer. A 1/4 hp motor will run on a light dimmer easily. I have a few set up that way. Cheap and easy.

Re: Dial for Drill Press Speed Control?

Yep, that's what I'd do. Remember, if a motor has brushes, you can run it through a light dimmer.

Re: Best way to pin Stephenson eccentrics

I'm always a bit leary of pins through shafts. It's too easy to take too much strength away drilling through, and if the pin is small enough to not impact the shaft strength it's too small to do any good. 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

Welcome, Jim! I think you'll find plenty of support here and I look forward to following along as your project progresses. 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

I'll come from a few years in the printed wiring board and 'puter electrical contact field. As he said, gold will dissolve in copper, slowly but surely. 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...

Re: Gantry Crane

OK, I get 2862 lbs. max SWL with load in middle of beam. 1795 A D /9 A= area of beam=2.87 sq. in. D= depth of beam= 5" 25758/9 = 2862 lbs. That should do it for you! This beam has a .210" thick web. It's been a while since I did this calc. so I had to get out the book and refresh myself. :roll: Pete

Hi Pete, the dimensions are 5” h x 3” w. Span could be 9’ but I only need 7’ if the span makes a difference.

Thanks ,

Re: Gantry Crane

I was going to figure out the SWL but I could not find a dimension for the span of the beam. You mentioned you had a beam 9 feet long but I don't know if that is your intended span?

I do need to know the dimensions of the beam and if it's a wide flange or standard beam
