Palbricks were quite unlike anything else (or at least, anything else built in quantity) were quite thin and had edges and handholds/lifting holes edged with, I think, some sort of metal sheet. The edges were similarly treated. As ever,
@hrmspaul has some useful pictures:

Obviously if someone is daft enough to make a batch of four of the things, it makes sense to mark them all out at the same time on a strip of 20 thou' (probably too thick). Of course, I had to make life difficult at this stage by making one Palbrick A which had a slightly different sort of centre stanchion...
The holes required a new scalpel blade and a bit of care, but even so I've marked out a couple of spares. Note that I've done one where the sheet has been replaced upside down. This seems to have been quite common (indeed, I have pictures with
both panels upside down - ) but I may or may not use it. I then made the liners for the handhold which even on a loaded wagon are visible on the inside too. I cut these from 5 thou', slightly oversize, and have solvent welded them in place. These will be left to harden up for a few days before tidying up and adding the edge strips. Even 5 thou' is probably a bit over scale.
No, I'm in no hurry to do any more, but since I've started, I may as well carry on.
