In Reply to: RE: Thorens TD-125 Sub-Platter posted by AudioSoul on May 13, 2017 at 16:32:11
Post a photo top and bottom of the subplatter, noting where the "warp" is. Maybe it could go to your local small-business type machine shop and be machined to take out the warp? I found an intelligent, reasonable priced machine shop / welder shop in OC by looking a a zillion Yelps...
A new subplatter could be machined from a billet. Not cheap either but a shame to let that 'table go to the scrapyard. To make an more-or-less exact copy - scanning it, creating a CNC file, aluminum, and machining - is probably $300-500 though.
A simplified design, say a solid cylinder of aluminum turned to the correct OD, a hole for the bearing shaft, and some clever workaround for those keyway holes, would reduce that to maybe $200.
"For Parts" tables comes up every so often on eBay- listen to your 124 while you wait it out??
If you don't mind me asking, how did it get warped? Looks like a pretty heavy Al or Zamak casting...
Follow Ups:
Actually, I don't know how it got warped. I purchase the TD-125 off of Ebay. When I received it, I went to town working on it. I found that the motor shaft was bent and got a partial refund for that. I didn't discover the warp until later when it was to late to contact the seller.....
I had a similar experience purchasing my TD124 many years ago on eBay. The seller didn't remove the platter before shipping as instructed but instead supported it (????) with a little bit of foam. The bearing and spindle assembly arrived obviously bent, but I was able to source a replacement. Once I got that sorted, I realized the aluminum platter was a bit warped as well, but I was fortunate to find brand new iron platter on eBay for $99 (obviously this was some time ago.) So I suspect your problem was caused by poor packaging in shipping at some time of its life.
Befriend a local machinist.
