Turning between centres to ensure repeatability when remounting the work in the lathe.
Forming the square shaft on the milling machine.
The completed barrel arbor.
Barrel construction on the arbor.
Turning the barrel end.
Barrel components (note that the arbor has been knurled ready for press fit of the barrel end).
Barrel locked into end plates to prevent rotation.
Wire groove cut into barrel. Note two errors here: 1st - grooves cut in wrong direction, meaning the wire anchor had to be installed at the opposite end to that specified in the plans. 2nd - grooves were not cut deep enough (due to concerns on barrel wall thickness), resulting in the grooves proving to be ineffective in ensuring an even wrapping of wire.
Cutting the ratchet teeth with a custom made cutter in the milling machine.
Good click engagement into the ratchet teeth. Note that the brass bolt was later replaced with a steel version, to increase strength.
FInal assembly (prior to drilling the wire anchor hole).
