Having created a space in which to build a layout I thought I would seek some advice. I found this forum yesterday when looking for sources of Sundeala. However, quite a lot of the comment on that material was negative. Quite whether the people who had used it and found it unsatisfactory had used it over a frame without anything beneath I could not determine. Clearly it is a material that needs to be laid on something substantial to prevent warping etc. It is said that before using it it must be laid flat in the room in which it is to be used.
I have several sections of exhibition stand framing. Egg box if you like. 45 x 20 lengths of wood made into frames, braced at regular intervals and some have sheets of 6mm ply laid over them. It makes them relatively rigid but nothing like as good as some of the 100mm deep frame others have used. When I built a layout for my father over 30 years ago this was what we used. On top of the ply I made the mistake of using insulation board, far too fragile and while it would have reduced the noise it was the wrong material to use. e.g. it would not retain the track pins properly.
The supports for the frames were simple 2" x 2" pine at the correct height for my father and screwed inside the frames. In order to ensure they remained in place we used plastic triangular bracket screwed into the loft's wooden surface. The sort of brackets that DIY stores used to sell for those making kitchen cabinets.
However, the floor of the new location is re-enforced concrete and I will have to create rectangular frames as the floor is also covered with carpet tiles. The frames can sit on top of 2 x 2 timbers that are screwed to the walls.
Assuming I make a nice, rigid structure, using my 45 x 20 wooden frames resting on the perimeter walls, possibly changing the 6mm ply for 12" ply (Birch or otherwise) what do I use as a baseboard top surface please, given the need to be easy to work with etc etc?
I will try to take a couple of photos. It would seem a pity not to use the frames. After all, I have been looking after them for a long time
