Dear Robin,

Regarding your heavy-duty banker construction, some methods I have used are:

1. Solid concrete masonry blocks from your landscape supply centre, I use
blocks 15"x7-1/2" x 4" stacked one atop the next on the largest face.
Several stacks will hold an enormous weight. Can be raised or lowered easily
by moving single blocks.

2. A 44 gallon oil drum cut in half and filled with concrete. I cut slots in
the sides and cast the concrete around an expanded polystyrene cleat so it
can be picked up with a forklift or a chain. The polystyrene is dissolved
with petrol after the concrete has set. The height can be adjusted by
stacking concrete blocks under the base. Makes a good flat surface to work
on.

3. A 44 gallon drum cut in half, and the two empty upturned halves bridged
with a piece of strong plywood. A timber cleat screwed around the underside
will stop it slipping off. OK for a dirt floor.

4. A frame made from square section metal tube, welded to make a low table
with a piece of strong ply screwed on top. Light to carry - or you could fix
wheels at the side of two legs so the table can be tipped and rolled along a
smooth floor.
