    It depends, what is really important is structural rigidity, so you don't lose fine motion cues.

    The other consideration is keeping the mass as low as possible for the upper platform.

    For both those reasons I consider aluminum is a better option than wood, though the latter could work.

    As far as aluminum extrusions go, I see Tnutz.com lists both lite and non-lite extrusions. Would the lite extrusions work ok? Thanks.

    I can't say, as I did not use aluminum extrusion products, but rather came up with a way to utilise common aluminum square tube and right angled aluminum stock to create a cost effective, light but rigid compact frame.

    If you use 3 motors and 1 cardan shaft in the middle, this will limit the "heave" shaft up and down. 3 motors will not go up and down at the same time
    can you post some pictures of the axes in simtool

    All 3DOF will have a heave range, all the way up to something like @SeatTime's large heave range: https://www.xsimulator.net/community/threads/seattimes-sims.11757/page-19#post-228726

    In terms of my Compact rig's novel heave knee, this earlier post gives an idea of the possible heave range: https://www.xsimulator.net/community/threads/dx-compact-simulator.5866/page-18#post-89768

    How does the bottom of the Universal Joint move?

    Please read the thread, as it is fully explained: it is an inverted adjustable tilt mechanism from a DX office chair, modified to take the Uni-Joint.
