The auto shock absorbers seem to be a bit of an
overkill. Besides the effort needed to compress them
is very high.

I would suggest a small rubber ball instead. With the
arm length needed for tangental motion, there would be
plenty of room.
Heavy duty rubber pneumatic cushions are in use don
trucks instead of the standard shock absorbers.
