Crankshaft and valve links
Crankwebs were drilled and then mounted on a rotary table to cut the radii. Silver steel was used for the crank itself and in normal fashion I drilled and pinned and Loctite'd the webs and then cut out the shaft between the crank webs. I used the Stevenson collet block to ensure the webs were 90° to each other. The connecting rods were next and I made a jig to hold them for machining. Various links for the Joy valve gear were made. The last job was to make main bearing covers.
