Hi,

There are as many buildung solutions as there are builders, space and spouse limitations notwithstanding. What works for me is an old steel desk covered with a sheet of gyprock, sheetrock, drywall or whatever plaster board is called in your part of the world.

The desk is flat, cost me nothing and the steel allows the use of magnets as recommended by Paul Johnson, Saramos et al. The qyprock takes pins well and after many builds can be turned over to a brand new surface and is cheap.

In my case I would have to "restump the shed" to take a billiard table but I'm sure this solution would work for some.

Cheers,

Colin
