I ordered 2 pots to replace the small one that come on the G0766. Hopefully they show up under the group photos but if not I'll upload them again. To make it work I had to oblong the hole for the pot as the new larger pot hits the plastic enclosure box. Also I had to cut the plastic tab off the pot used to keep the pot from turning. I could of drilled a hole in the face plate for the tab but as long as the nut used to hold it in place is tight it provides more than enough to keep the body from moving. There's a small hole that looks like it could be used but the old pot doesn't have any way other than the nut tight to keep the body from spinning. I put a 3/8 washer on the inside and outside colored black with a sharpie. I was concerned that the + and - sticker for the speed control might be covered up by the knob in the higher location but it's not the case. I also used quick disconnects on the pot to make replacing it easier in the future.
If you do a search for "WX050 Carbon Potentiometer" you should find plenty of places selling them. It's a 5 watt pot so it should have no problems replacing the smaller pot. The first picture is the old one on the left and new one on the right. The second is how much I had to reshape the hole. The last is what it looks like finished.
Alex, were you intentionally looking for a 5 watt pot or is that just what you ended up buying? Let us know if you have any issues with the pot.
I wanted to have a spare or two sitting around in case mine died. For the price I didn't want to be down waiting on a replacement. I did some searching on line for the same resistance but higher wattage (to hopefully last longer). There were hundreds of different models, this one was one of that was close. When I found it on Amazon some else wrote a review saying they bought it for their Grizzly (lathe I think) and with a little modification it worked so I figured I would try it. If I have any problems I'll report back.
Right now I have two (cheap) spares. Having quick connects makes the replacement quick. I have little wire-nuts which also makes it a quick replacement. I did some Googling on potentiometer life. It seems that the standard run-of-the-mill pot is spec'd at 50,000 rotations. There are a few that have a rotational life around 1 million to 2 million. This includes the https://www.vishay.com/docs/51056/p30l.pdf (Visahy P30L series) and the https://www.bourns.com/docs/product-...rsn=1de576f6_3 (Bourns PDF24 series). I think that one is cermet and the other is a carbon polymer. I have no idea how they get the life that high when 99 percent of the pots have a much lower life. When I get down to only one spare pot, then I'm going to buy one of the "long-life" pots. At that time, I'll study the physical dimensions a little more closely to (hopefully) avoid needing to modify the lathe. Thanks for posting your approach.
