Fig. 2 Close up of mod block and ring. The clamp ring is shown upside down to reveal its details. On my turntable I did have to pay careful attention to where the drive belt rides in height and I ended up having to lower the height of the lid covering the motor pulley to be clear of the clamp ring when in use. Block mount holes were drilled and tapped with platter removed and soft-block clamped to a work table. Mod blocks might also work okay if fixed in place with good double stick tape - not forgetting, of course, to account for tape thickness. In fact this brings up a good point: I made sure to make the blocks a very slight bit thinner than the numbers indicated, and used one layer of double stick tape to make a shim to customize the fit and feel of the ring/platter. There are two locations where one can shim for fit - behind the blocks or behind the felt strips.
