@terry9 Would be interested in your tonearm design, have a turntable that could use one...as well as a deck for the table itself. Since I work with locust (robinia), I've lots of 'drop' planks as thick as one could care to apply....
Hard and dense, laughs at carbide.... ;)
DIY TT switch for 3 tables, the 3rd needs an 'input'...allows for RIAA (or not) and anything else I'd care to run 'in' or 'out to'...
DIY 'stand' for all; two 1" thick slabs of polished stone supported by a heavy pine frame. Takes 2 to think of moving it...bumping it will hurt you before either TT notices it.
Anything that can rack mount is, and is on the above as well.
Have built speaker cabs of various shapes for the 'typical' sort of drivers. Most of that takes a back-seat to the DIY Walsh drivers I play about with for the last 15 years on and off....
Some berserk concepts of a surround AMT array with a distributed sub array to go along with a surround Walsh array is pending, but will await moving lock, stock, and everything else to a new home in a vaguely sub-rural location. That in itself will have 2 spaces open to treatments as desired.
One of which has the SAF issue, but as long as it has 'plug & play' simplicity, she's good to go with it. ;)
All of the above is dependent on the 'spare time' that I've in limited quantity, but I'll manage....*G*
