Machined two aluminium bronze Gipsy Major heads to suit oversize exhaust valve guides.

Cool job, had to check a Gipsy Major propeller hub for true and machine the countersinks on the face, even had a drawing to go off.

Made ten hinge pins for a customer, grooved for grease, the main body is 38mm diameter 150mm long, with a 60mm diameter 10mm thick head,1040 steel is nice to machine.

Weld repair to a CR 250 rising rate linkage and a skim off the inside bosses of the swingarm in the mill.
