They also never seem to have traceable boiler history with them

Hi Terry the lower shaft should have a keyway in it and the cutters are locked to the shaft with a square key and the spacers are put on either side and done up very tight.Mine is left hand thread and it is no good photographing it because it has not got a keyway in it yet.

If you make your own fittings they are not going to be CE marked any way.

Why do people go on about verniers and digital calipers in the inspection department they were classed as adjustable spanners and just about as useful.

The op says "The Zeus table says the clearance size of these would by No 40 drill - ie 99 thou diameter."
surely you would not expect eight studs to line up on the threads and slide straight on you need some clearance to stop it jamming.

I had broken a 3ba tap half way through a 2" square by 5/8" thick mild steel bar with about two hours work on it, it would not come out with a centre punch so i heated it up with a gas torch as hot as i could which was dull red and let it cool down slowly.When it was cool i found a 1/8 tipped drill and put the pillar drill on it's slowest speed about 160 revs with a fair amount of pressure and it slowly came out as a black dust.The thread cleaned up with another tap, have i just been lucky or is this possible with carbon steel taps.

Hello everybody i started to strip the cylinder and the piston measures 1.373inches and a groove .050 deep and .100 wide, the piston rod is .234inches or 6mm with a 1/4x20 whit thread which is very flat topped which i tried to show in the photo.In the other photo the end plate the arrow shows a hole tapped 3ba and the other end plate is the same.The two bosses on the steam chest are tapped 1/4 whit but i cannot find anything in my collection of bolts or taps to match the boss on the cylinder who's core diameter is about.175 or 4.5mm.

Hello thank you for your comments, i have not taken anything apart this is how the engine was given to me. The crank web looks as it could have sheared of but the damaged metal is only about is only about 40 thos wide it is more like a chamfer. but the end of the main shaft looks as though it has sheared completly.The friend of a friend who gave me the engine thinks there might be some small parts somewhere but they have not turned up yet.I have posted two more photo's to try to help.
