I would have though some one as clever as you Merv would realise that the E is next to the R on a key board & it should be PORT. Beside the fact I never cood spel.

Marv, poet block is a form of writer's block, notably when you can't find a word to rhyme with "orange"
It's been said nothing rhymes with orange. They're wrong. It doesn't.

Sorry, Hummer, I don't have the patience to do combinatorial analysis on what people write. I'll deal with it another way.
hammer:
Turned the bearings from the same hard brass used for the piston. Completed the crank & shaft, threaded 3BA fixed with loctight. Just need oiling holes in bearings , polish and final alinement when bolted to the firebox.
Also in the picture springs from an assortment of ballpoint pens will find one for the safety valve. The 2 lumps of brass are for the flywheel, the smaller bar will have to be silver soldered into the hole in the other. This was found at the local scrapyard and had the centre removed. The plug is for the level hole, it is important to undercut the seat so the grommet can't push out under pressure. Not that much pressure will be involved here. But a lesson O:-) learned when testing @ 50psi.
hammer:
Mark 2 safety valve. Managed to reduce the size. First by hollowing out the underside of the adjuster to take the end of the spring. Also lowering the ball seat down from the body into the thread area. Completed in an hour, by keeping the same thread 5/16"+ 32 for the adjuster as in the boiler bush. First thread to fit bush & centre drill, open out 3/16" for full length of body & part off. Drill & tap same thread in the piece left in the chuck & screw the body in. Push back into the chuck, drill the seat with a 3/16"D bit , then drill & tap for the adjuster, carefully measuring depth each time. Pull out and remove the body, tighten & part off 1/8" for the locking ring. I turned the plunger from 3/16" hexagon this fits the hole but lets steam out. Finally thread 5/16" rod drill centre grind 4 slots around edge then part off & assemble then set 20psi with air line.
Lagged the boiler, where did the raw materials come from?? Sticks stuck on with 5min epoxy 12 at a time. With approx 1.5" to go measure, then measure across the laid sticks to check the fit. reduce remaining sticks slightly if needed, no one will notice, thinking I worked it out mathematically.
