On to the crankshaft the parts machined to size and drilled where needed

The crank was assembled by loctiting the parts together then cross drilling and pinning with a tapered pin once they are set the pins are cleaned up and cannot be seen

The next job was fun as I had to use a 3/32" cutter to do the slots for some 1/8" this had to be done in three passes for each slot and was very slow as cutters this size will break very easy if pushed too hard

The finished crank with the centre pin removed as that was keeping the parts in alignment whilst it was pinned together and any other jobs
