I hope this Vid comes out OK, i first ran the engine on air, but steam gives it another dimension, I think!
The vid seems to show the engine running anti clockwise which is not the case, and the faster the revs the slower the valve linkage appears to move! very strange!
This engine can run at quite high revs, so much so, the grub screws i made (with slotted heads) flew out! hence the odd looking screws you might notice
i think i mentioned my bad steaming layout, you will see one exhaust blasting on the oiler which keeps it nice and hot! not quite the right idea idea :-[
There were no leaks on the engine other than the ends of the valve rod, which were as in the plan, i put oil grooves on the pistons "alla Stuarti used 0 rings under the manifold, and tel's method for sealing cylinder head ie PTFE tape twined around head studs, no gaskets, as i said no leaks most of the steam is coming from the safety vale on the boiler and the exhausts
I did do a spasmodic build arrangement as i went along with pics, but now it would be retrospect ??? but can attempt to post if anyone is interested
