We are proud to offer our welding services to repair cracked cylinder bases, fin repair and valve seat cracks to bore. All repairs are done with Nickel rod. First they are heated in heat treat oven then hammer welded with nickel rod and allowed to slowly cool in the heat treat oven. After welding of bases or valve seats, the cylinders are machined square and re sleeved with a new cylinder liner to orginal standard size of scout or chief cylinder. In the instance of the crack at valve seat, the cylinder gets a new valve seat to remove the stress on the weld of the compression gases. All fin repairs are domne with steel fins that are cut to fit and welded on ends of repair. The repair is alnost undetectable on an assembled engine unless you are really looking for it.
