RE: Looking for experience in damping material
Posted by Bill Way on March 1, 2013 at 19:46:11:
For my TD125 I made an arm board of a plexi-lead-plexi sandwich, epoxied together. I think the lead was 1/8" or so. Very easy to make: you can cut the lead with big snips, and the plexi is easy to cut and trim (use a small rasp plane to smooth the cut edges.) I think I got the materials on ebay. Merrill used to make an add-on lead platter mat, which I epoxied to the outer platter after making a jig to get it centered. I replaced the springs with 1"(?) sorbothane spheres, which made a huge improvement in imaging, at the cost of less feedback isolation, so I spiked the whole thing. (The spheres get better after a few years as the sorbothane squashes more and gets a little firmer.)
I haven't opened it up in ages, but seem to remember cutting a few lead sheet pieces to glue to the subchassis cast aluminum parts.
