Building a model railway baseboard

[Harry50]

I'm building my first baseboard from plywood and birch. I've built the H leg assemblies, but now the design calls for 'locking washers' for the angle braces.

I've had a look online and there seems to be different types with different teeth. I'm not sure of the different purposes for internal locking washers and external locking washers and fine tooth locking washers. Which type should I use?

 

Thanks

If they are timber locking washers ( a washer with a saw tooth edge) they are not required.

Are you going to ever be disassembling it?

Because if not, why not just use wood glue and screws?

We are hoping to move house soon, so I'll need to disassemble it at some point. 

I think the locking washers are included in the design because they stop the fixings from working loose, so I've bought these: https://www.accu.co.uk/20-locking-washers.

Harry,

 

If it helps, I've built my baseboards and baseboard supports to be 'dismantleable'. The support framework is screwed together, and the baseboards bolted together; all using off-the-shelf bits. No glue involved at all.
