What I have done with these salvaged Exeter-pattern joiners’ hammers is to forge the cross peins into a curve on my swage block (qv) for the purpose of fullering a bick on an anvil bridge.
This is the last bit of 1&1/4” plate I salvaged from Howard at Shadow Supplies. It was probably part of a digger bucket. I am just doing this to extend my techniques, I already have an anvil bridge. I only have the energy to forge for a couple of hours, so I am wasting fuel reheating the block over and over. What a pity I have no striker!
The fullers were normalised after forging, not tempered, and are standing up well.
The hardy tool is a clip I made specifically to hold the block on the anvil while fullering. The block has jumped out once only so far!
