OK, thanks gents.
If one uses coupling/decoupling spikes on both the
motor assembly and the arm/cart assembly, and the
spikes go into something "soft",i.e., a piece of wood,
the SAME piece of wood, that is, then I can see that
the spindle-pivot distance can be maintained.
The question of both assemblies being vibrationally
isolated from each other, in this instance, is topic
for a different post.
My interest here is primarily how to maintain the
spindle-pivot distance (while observing motor-cart
isolation). Two big weights could possibly drift apart,
or the dog's tail could move one of them, etc.
Banquo, it's comforting to read that you've had
good luck with your setup.
For example, one could not place the two assemblies
in a box of sand, or on a big lump of clay even.
Possibly I'm making too much out of this issue.
I'm seriously considering such a project, and I want some
certainty the design will work once I start spending.
