I have a Delta 7 inch shaper that I need to mount.
I was thinking of bolting it and it's motor to a thick
board. That way I could push it aside when I needed
the workbench space. However, I am worried that
it would jump around too much if it is not bolted down to
something more solid. I have never used a shaper before
and so I am not familiar with how much they jump.
Is a heavy board sufficient or do I need a heavy
table?

Thanks,
Pete.

You'll need something besides a board. The ram is fairly heavy and
the inertia will make the thing walk. It'll need to be bolted to
something pretty solid. My AAMCO has about a 2" thick laminated
mounting board with cast iron legs, the stand probably weighs about
100 lbs. It's still too light for high speed running, as it is, the
stand sways a lot when making full-length cuts.
