    2 speed 3 phase motor?

    If its just the shaft that connects it, make another one. You could probably figure a way to manually switch it with a wrench or something (WITH THE POWER SHUT OFF TO THE CABINET) and see how it runs in both speeds. Might have a bad winding in one of the speeds or a bad contact tip in the...

    WTB: INSIDE jaws for a Cushman 6" 3-jaw chuck

    I have the same chuck. A few years ago i contacted cushman about buying new jaws and nothing was available for it. Someone might have an old set for it, but it'd be a long shot.

    Towmotor forklift parts

    If there was a military version of it, you'd have better luck trying to find the Army TM for it. There may be reprints online.

    Preferred lever chain fall?

    We use the harrington LB series in our plant. It's welding, heavy steel fab, shipyard operations. We probably have about 50 of them from 1.5t up to 6t. The guys beat the shit out of them and they hold up very well. Thrown around, pulled through voids, dropped etc. They need repairs from time...

    Welding gloves

    If you're doing small parts i'll assume you're not doing a lot of welding on them. Try TIG gloves. They're thinner for better feel, but can't take as much heat. Go to your local weld shop, or (gasp) Harbor freight and try some on. The gloves from hobo freight are pretty decent quality for the...

    VFD for 3 phase to single for Surface Grinder - Advice Please

    You'll need a 3hp unit if your motor is 2.2hp. You dont want to undersize it. There may be some 2.5hp rated units. You'll probably need a 220v single phase input. I dont know if anyone is making a unit that big in 120single to 220 3 phase. Since you know nothing about it, you may want to...

    Looking for 7/8" - 4 acme threaded rod

    Could be. I'll take a closer look. It's definitely not 6tpi. It measures at 4tpi.

    Looking for 7/8" - 4 acme threaded rod

    I want to repair and old Ridge Tool vise. the lead screw is 7/8" diameter, 4 threads per inch, looks like Acme thread. I can't find that size and thread count as a standard acme size anywhere. Am I out of luck on this? I suppose I could size it for one that is available and change the nut, but...

    Drilling a 9/16" hole in ~2" thick rubber

    I have some tubing ordered to make the cutter. Your comments about having a pilot hole make sense. We'll try them all out and see what works! Thanks everyone.

    Drilling a 9/16" hole in ~2" thick rubber

    We need to drill some 9/16" holes in rubber blocks that are about 2" thick. These are part of an assembly and have to be drilled in place, horizontally. We have a mag drill with a regular chuck and one with 3/4" weldon chuck for slugger cutters. We are using punches for the 1/2" thick...

    Gravity powered ropeway

    It only works when material you're moving is always uphill of the final destination. For a mine like this, it's ideal. As mentioned below, the topography of the land has to be right for it to work too.

    Which VFD will do what I'm trying to accomplish?

    Can you run a VFD off a rotary converter? If I were spending the money on a VFD, I'd see if someone makes one rated 7.5hp with single phase input and eliminate the RPC. Sell the RPC and offset the cost of the VFD. Most VFD's can do what you want. Those functions are pretty simple. Call your...

    Recent band saw purchase

    I would stay on the vendor or manufacturer with these problems. Bad blades can cause crooked cuts just as much as being out of alignment. This guide from lenox is very good about explaining the blade selection and setup - https://www.lenoxtools.com/Guides/LENOX_20Guide_20to_20Band_20Sawing.pdf...
