Updated Rowlocks

I’m making a few mods to the Mary Chamber model to make sure that the rowing action is a full back and forth movement. First thing to change, the rowlocks. In the current version the oars sit in a simple fixed wooden U shaped cut out, I’m making a new version where the U shaped section is made from a sheet of shaped brass and is free to rotate allowing the oars more movement. The brass section is fixed to the boat, the steel section sits in the brass tube and is free to rotate. The U shaped section is screwed to the top of the steel section.rowlock08

I’ve cut the steel section from a 6mm diameter bolt. First things first, the steel in the bolt is hardened so it needs annealing. I heated it up to red heat with the blow torch.rowlock02I then let it cool down slowly in a bed of sand. I repeated that process a couple more times.

Here’s the annealed bolt ready to go in the lathe. It will need the head rounding off then a suitable hole drilling and tapping. Finally it will need cutting to length
