Technics SL1200 Footer thread size?

The adjustment range of the Technics footers is about 1/4" from what I recall.

Since I'm no longer using my Technics footers, I measured one and the stud is just short of 1/2" long. Of course, the adjustment range would be less than that as you'd need to leave a few threads screwed in to the base for stability, so Tvad is pretty close, maybe just a hair more than 1/4" total.

The studs on the Parts Express cones I use are much longer, so the range is probably 1/2" or more. Since the cones also have a threaded receptacle, you'd need to leave a few threads screwed in on both ends. If you need an inch or more of adjustment range, I don't think they'll do it unless you buy some threaded rod and make longer studs.

Having an inch of M6 threads exposed would be far less than ideal. I've thought about applying some Loctite to the cone ends, but haven't done it yet. That might lend a bit more stability. You could also try nuts to back up against the base and cones. If my floor were as uneven as yours, I'd make wooden spacers (in place of the coins) that would get you in the ballpark of level, then only do the fine adjustment with the feet.

Yeah, Armstrod's right. I'd say I had a hair over 1/4" total. More like 9/32".

Bondmanp, I'd recommend you try to get your rack as level as possible so you don't have to do all the correcting at the turntable feet. What kind of rack are you using? Surely you could put some adjustable feet on the rack as well? If your rack feet are adjustable by 3/4" and your turntable by 3/8", then you have the range you need to level your turntable. Or you could get a wall-mount rack for your turntable so it's independent of floor aberrations.

Bondamp, various thicknesses and durometers (softness) of sorbothane sheets can be purchased at resaonable prices from Mcmaster.com.

I used a few stacked pieces of 1/8" sorbothane to level my turntable when the adjustment of the footers was not sufficient. I recommend 50 durometer or harder. Anything softer will deform if too many layers are stacked.

Mcmaster.com calls the material soft polyurethane rather than sorbothane, but a search for sorbothane will return the correct catalog page.
