Hi Nandric, I had similar thought about machine shop to make my own arm board also. Many of my friends use these shops to make arm board for various arms so I do have access to some local shop here, both metal and acrylic. Unfortunately in the case of SX-777, to install 66s, I would need to cut a new hole on the table itself as well since phono wire came out from the bottom of the mount. With the standard arm board, in the usual position on 777, no matter where I cut the hole on the armboard, there is not enough distance to accommodate 66s P2S.
Right now I am perfectly happy using 66s on my "other" turntable :)
