Hi Stew, I haven't been able to follow this thread for a couple of days, and you've done some very fine work. Your attention to detail is apparent in every little bit you make. I'm getting a real education on this build log. I've long wanted to see the inside of one of those pumps, and you show it off very well. It is gorgeous looking as you build it. :beer: Cheers, Jack |

Thanks a lot Lads Little more today Made the spool valve, from 4mm stainless steel you make it like a dumbell the middle bit is only 1/16 dia so it need some suport from a centre, I made it over length for the centre and faced the centre out to get the correct length. And how it fits in the engine the inlet valve is activated by the valve rod the exhaust valve from the back pressure in the cylinder moving the spool valve. Just the clack valves in the pump to finish off and a final assembly then we can see if she will pump water. Stew |

I got to get my grubby gorilla fingers on this beauty this afternoon, when Stew called in for a gum beating session. If it runs as well as Stew has made it, it will be a stunner. Stew makes light of the machining part of this project. It is in fact a very precise machining exercise, like a steam powered swiss watch. Very well engineered Stew, a real credit to your skills.

Thank you very much John much appreciated. Well I lost round one at getting to work, took me ages to get my head round how to set the timing at last I figured out that due to the rod stops and the configuration of the steam way that it work back to front to a more conventional slide valve set up, when I eventually got it sorted and subjected it to air found that I'd got a huge air leak from the bottom steam chest cover. At that point decided I needed a cuppa and a bit of cogitation time. Round two start this morning Stew |
