A good few hoiurs in the workshop later...
Steam Valves are complete and work. Just need to attach the Packing glands.
Remade another spool (that's the 7th started so I'm quite good at those now)
Made the M2.5 Studs from a welding rod.
Made the steam valve end plates.
The Piston block is now assembled and complete.
Made the eccentric straps (rather badly I have to say) I'll have another go at those.
Remade the eccentrics in Ally - Nylon was just not going to work.......
Stripped the crank and put the oil holes in the bearing blocks.
Also did the cutout for the eccentric on the Base Plate.
I noticed some play in the chuck whilst cutting up my sash weight so ended up stripping down the Lathe Headstock.
The bearings are in very good condition all things considered. (It's an ML7 made in 1954)
A Bit of blue greasy gunk showed the top shell was lose but the bottom was sitting really nicely.
I re shimmed the blocks until there was a tiny bit of friction then added a fag paper.
There is no play and the spindle runs freely.
I'd also note that Oil Consuption has dropped dramatically

.
I may get some more time to play tomorrow.
Alex.
