I have made the other valve rod fork and to drill the slot hole it is held in the vice dead square by placing it on the flat steel and putting this machine vice over the top. the engine is close to completion with most of the parts made and the valve rod connections made ... they will need to be adjusted on the crankshaft though. Also a nifty tip I have thought up and tried out for when I make the inlet steam valves ... is I need to file the square on the wheel and rather than filing it I just drill a hole and use the file as a broach in the drill press and just push it through....
this saves a lot of work ..!!
4 o'clock was just arrived as the clocks have sprung / springed forwards
