Not quite a build log - since I'm half way through and have taken no photos (until now), but I thought I show it anyway
Base, sole plate, standard, cyclinder, crank, mains, bottom cylinder cover & gland, piston rod and con rod have all been machines (as per pic below).
Also a pic of the jig I used to machine the crank main (crankshaft is a casting on this engine, ends are centred and main shaft machined to size both sides, then a pair of holders are made up and clamped to the shafts to allow the crank to be offset to machine the bottom end).
Most of the rest of the machining is fairly standard, holes have all been drilled using a mill with DRO, cylinder holes drilled using PCD on DRO. The steam chest has been drilled to take the reversing gear. Next task is piston and top cylinder cover - then the core of the engine is done. I'll then start on the reversing gear. (Pics to follow).
I'm quite pleased with progress so far, I'm slowly but surely finding my ability to machine parts accurately improves. In fact I've a set of castings for a Stuart Major beam and I'm feeling fairly confident about starting them (I'll definitely do a build log for that).
Engine before this was a Stuart No8 - once I've nailed it to a piece of wood I'll post some pics.
Parts machines so far.
