Article on choosing plywood

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

Article on choosing plywood

Postby PeterH » Sun Jan 27, 2019 12:24 am

Here’s a link to a good article on choosing plywood:

Plywood quality seems to be going down as manufacturers try to reduce prices. The race to the bottom. No wonder modellers make foam baseboards.

I am in the UK.
I am not sure that I would be expecting to do furniture level of woodwork for a model railway.
I specify a lot of plywood for construction in my job. The problem we have is the assumption that plywood is a cheap solution. I have to make sure that it will do the job it is designed for - ie with the right glues and timbers for the application.
If you scroll down there is a really good article about building applications here

I would assume that the ply in a model railway would be used for the framing and track base as well. I am thinking of using exterior plywood as it may have to last a long time and may go through some changes in temperature in its life.

Does anyone have experience of making ply framing for baseboards?

My layouts have been small, so I’ve used a block of that cheap polystyrene foam and run something around the edges to protect it (1.6 mm mounting card).

Bigger layouts need more substantial engineering to cope with detachable sections, legs, changes in climate. All-wood construction tends to be heavy and a lighter way is to use foam for the middles and thin ply glued on for the edges.

There’s a lot of information about this on the internet. I think most baseboards are way over engineered.
