Anyone know where to find any?

I'm looking for summat like 18" dia by 18" long, 2 off.

dia is variable up to a point, 16" or 20" might be OK too.

I'm trying to make a motorised roller - got an engine from an old mower. I
have in mind to make hollow rollers which can be filled with water when
needed for extra weight. Might add an eccentric so it'll vibe, too.

Here across the pond these things are generally made from old air or water
tanks. Old water heater tanks are pretty easy to come by.

I made mine from a 19kg-size propane gas cylinder

Now, that's a possibility. I was looking for 2, but that's not much harder.

You really need 2 eccentrics rotating in opposite directions and timed
so that the horizontal vibrations cancel but the vertical ones add.
The weights need to be together at the top and bottom but when one's
at 3 o'clock, the other's at 9 o'clock.

Large steel pipe's not so easy to get hold of since everything went to
plastic. You need a fairly thick wall as well to take the mechanical
forces. I made my roller many years ago and filled it with concrete.
The removal company loved me when I moved house.
