NOT at all !! I appreciate the time your taking out to post your comments and advice - they have helped me no end! I`m just going down to the workshop now to drill the cylinder ports....so fingers crossed! I`ll keep you posted.

I don't know if you need it pressurised - but if not, how about making your own - get some handfuls of Calcium Carbide and a cup of tap water and craft a nice drip feed like a carbide lamp?

Hi Dave, I don't mean to keep it off topic, but where do you get Calcium Carbide in handfuls? I can find a source here for a one or two ounce tube, but that's all I've found. I could use some for a lamp I've got, and I'd like to build an engine that runs off it. That was the standard way to get acetylene all up through the thirties and forties, for welding. Info would be highly appreciated. :scratch: mad jack

Hi Chris, thanks for the good word, it'll be another week or so before I'm working on projects again, still cleaning, so I am really getting great pleasure out of watching you, as you're cracking away at it, and I wish I could be doing the same, or perhaps making a visit to your shop. That's the one thing missing from these forums, we can be so far away from each other, yet truly enjoy each others company in exchanging ideas and experiences. I seem to learn something every day from the various backgrounds and experiences of those who are building, and enjoy it thoroughly. I'm looking forward to seeing your ports turn out well, so you can get on with mounting valve gear and steam box and the like. Your's is like a kick in the pants, as my engine has been in the shop, waiting, for close on to seven or eight years, and seeing you build is driving me to get mine done, I want to actually steam it, I've only used air for engines before. great job, looking good. :poke: ttfn, mad jack

Cheers MadJack. I don`t know if I`m doing it right but I`m doing my best!

I`ve still been working on this over the weekend with some progress and what I did attempt seems to have gone well.
I first finished off the cylinder and also drilled the steam ports including drilling and tapping the exhaust. I must admit, I tapped the exhaust a little near to the edge than would have been ideal but it still worked out OK – no problems and looks just fine. The steam ports drilled just fine as well, no problem there and the cylinder looks very good. More pictures at the bottom, but this shows the ¼” recess on the cylinder bottom:

Got going on the cylinder covers. I wanted to use my rotary table to drill the 5 holes accurately so I turned to length on my 4 jaw, cut the recess that registers with the cylinder bore and then pulled it off the lathe and transferred it to the rotary table.

I then made some more markings and started to part it off:

Cylinder now finished and so is the top cover. I need to drill and tap the cylinder for the cover but I`m going to use the cylinder cover as the jig to mark out the position of the holes. I`ll do this later when I`m definitely happy with it all

Next job is to do the bottom cover but it tells me that I need to ream 5/32” and I don`t have this sized reamer. Truth is, I only have a hand full of odd sized reamers. I`m reluctant to buy a 5/32” reamer to use it only once but of course the rod going through which is supplied is 5/32”. I`m considering buying a metric reamer set and buying some 4mm silver steel and using this instead!?
Chris

kwackers:
There's no problem changing the size of the rod and reaming to fit. Remember to transfer that size through to everything it connects to. (Off the top of my head, that'll be the gland, slide valve & nut and whatever the connection to the eccentric is).
(Worth bearing in mind a 5/32" reamer is £2.75 from Arc Euro - is it worth the hassle?)

With regards 'sets' personally I dislike them. They're handy to have for emergencies but the quality is always a bit 'iffy'. Much better to buy high quality individual items.
All IMO, I have lots of sets of various items but the stuff I use most frequently is all purchased individually and I've always found it to give better results.
