Piece was spoken for and shipped.

If the original poster isn't interested in the VFD, I would be. Steve I got a TECO JNEV-101-H1 brand new when I got my machine. But it doesn't have the capacity for my machine and has been on the shelf ever since. Is this something you could use? (1HP/750 Watt) Just like this one: https://dealersel...

Should only need two contactors. Go on ebay and look for three pole contactors. Chinese pieces are <$10 each. American quality may cost a few dollars more. I can't imagine that you would need to switch more than 20 amps, but you can easily find them that can handle over twice this current. These are...

After a bit of thought..., cheapest and easiest way to go with no concerns for power handling, because you can get big-azz contactors fairly cheap. Use two three pole contactors. They can be low voltage with a wall wart, or full 120 or 240 volt. Use a dpdt center off toggle switch to send power to w...

So glad it worked for you, and now I know that if I have the problem with mine, I can rectify it. You owe me a steak.


I assume that you saw the threading instructions that I posted?

Thanks. Any suggestions on a 3P2T switch? Don't use a switch. Use a 12 volt contactor and use a wall wart to switch that. That's how I did my table limit switches. In fact, I never switch the forward/reverse "on switch" for either the lathe or mill when live. I always leave the contactor off until ...

Like I said, I bought three replacement spline shafts from Smithy and they all differ by just a hair Smithy spline shaft (extras): across round portion: #1-0.578", #2-0.578" (very tight fit on my gears, but they do go with minor coaxing), ShopTask original (broken in length, cracked in diameter), 0....

An update: When my machine broke the spline shaft for the threading gears, it was not Grizzly I got a replacement from, but rather Smithy. Go toward the bottom of the page and look at the Pulley Box, Diagram #14, Part #C30143, Gear 27 Tooth. Could this be what you need? And if it is not, could they ...

Just so you guys know, this is what he is dealing with. If the broach cuts "perfect angles" that may not quite line up with the spindle, which is "sloppy" toward the base circle, though it would probably work with a bit of filing. http://www.audioheritage.org/photopost/data//500/medium/20201215_1144...
