Recently got back into ceramics after taking a class to continue my art teaching certification and loved it so much that I decided to set up my own studio (which I will be posting a lot of questions about soon, I'm sure). I purchased a bunch of stuff from a woman that was selling off her small home studio, including a Brent IE wheel. I don't think she used the stuff hardly at all, but looks like it was probably sitting in her shed or something for several years. She likely purchased it used as well. Cleaned it up, tweaked a few things, and seemed to be running fine for a few weeks. Haven't used it heavily, but probably thrown a couple hundred pounds worth of clay on it so far. So, was just spinning the wheel slowly the other night while I was scraping off some excess clay and it started vibrating really badly. When I tried stopping it with the pedal it continued to rotate maybe about a quarter of a turn or so after depressing the pedal before completely stopping. When I first set the wheel up it would rotate a little bit on it's own, so I adjusted the speed controller in the pedal and all was fine. The other thing that concerned me is that I was smelling hot/burning electronics. I checked the belt and it seems to be ok and have decent tension, but I don't really know. Not sure what else to check. The wheel doesn't have a ton of torque as it is, and I could pretty easily slow it down with dryer clay, but it took significantly less effort to slow or stop it after this issue popped up. When I called Brent they told me to take it to a shop or have someone come look at it (Kiln Doctor, since I'm in VA), and I also read in another post that that's pretty common from Brent, not doing much as far as troubleshooting over the phone. I have been hesitant to fire it up at all to test anything due to the smell of the hot electronics to avoid any further damage. If anyone has any suggestions of where I could start looking for the potential problems I'd greatly appreciate it. I'd rather not drop a bunch of cash having someone come to look at it if it's something simple. Thanks in advance!
