The Best Thickness For Plywood Model Railway Baseboards

What thickness of plywood is best for a model railway baseboard.

As I discussed here, plywood is the best material for a model railway baseboard but what thickness should you use?

The thickness of the top I and most other railway modellers recommended 9mm or 12mm.

Anything less than this will be insufficient and will be prone to drooping or even twisting and may not support screws used to secure underboard mountings.

Equally, anything thicker will make cutting through for electrical wiring tiresome and is likely to be too thick for connections from underboard point motors to reach through.

Alternatively, you can also make your baseboard top from expanded foam, this increasingly popular and has a number of advantages as explained here.

Take a trip down to B&Q or other DIY store to get the wood and come back here and let others know how you get on.
