Since the seat is on casters, mine qualifies as Movable, although I have no intention of moving the wheel stand.
Cobbled from scrap 5/4 yellow pine and a
folding clamping Work Bench,
this wheel stand is acceptably stable and rigid, with movement visible only between its feet and carpet
and not sensed when driving in VR. In the dark, wearing Odyssey+ HMD, it looks great!
Tactile feedback is courtesy of
SRS ShakeSeat, SimHub, motherboard 7.1 audio and a pre-HDMI Denon 7.1 receiver.
Obligatory extra padding for ShakeSeat was cut from a square of 1/2" interlocking EVA foam mat.
The (not very) hardest part of implementing this tactile feedback was identifying a mating connector for the SRS ShakeSeat.
The AccuForce hybrid step motor is bolted thru 5/4 yellow pine; its cables are strain-reliefed by a clamp to side board:
When driving, castered swivel seat is strapped to workbench front legs, which are in turn strapped to a board bolted to G29 pedals,
which are modified with DIY degressive clutch linkage and load cell brake.
Thanks to the magic of triangulation, strapped seating position is quite stable:

My AccuForce is blessed with one of the noisy controller power supply fans, placed as far as possible from the driving position:
G29 pedals are connected via an adapter to the AccuForce controller.
