Oh,I see it's one of those 'We'll just machine some bits of metal and decide what it's gonna be later on'

If you want a good laugh you want to see the sizes of the cast pipe fittings my mate gave me a couple of weeks back. They came out of an old commercial laundry business and there is nothing smaller than
1.5 inches dia :jaw: and a few are 2.5 inch dia.

I think we may be stretching the definition of 'Model engine' if I use them :lol: Maybe I could hook it up to the 1 kilowatt Markon alternator that I have kicking round to provide a back up gen set for those power cut eventualities :lol: ......OZ.

That's what I call planning ahead.
All the planning is ahead of me! :beer:

Hey, 1.5 inch bore ain't exactly a mill engine. Get crackin' ! :poke:

Uh, happened to discover a 3/8" mark on my cylinder, so I guess it was a 3/8" pipe union, not a 1/2" as I originally said. Now it's 3/4" bore, though. :dremel:

So today I dug out a (I think) 1" galvanized pipe cap with a hole in it from an earlier experiment with pulse jets. The hole was off center, but I planned to drill it out big enough to get a boring bar in it, and then true it up to center. Unfortunately that didn't go well. I chewed up the end of my 5/8" drill pretty bad before realizing there ws a hard spot in the cast iron. :doh:

Well I don't have any carbide drills, so after thinking about for a bit I figured I might try to see if I could anneal the darn thing in the woodstove in the house. It had a big pile of hot embers in it (it's been super windy last night and today and we're headed down to the negative numbers Fahrenheit for the next week) -- being well stoked. So I buried the fitting in the embers and opened the draft up, and let her cook. I figured it would also deal with the zinc coating -- right up the chimney.

When I pulled it out cherry red, I buried it in some wood ashes in a bucket. A half hour later this is what it looked like cooked. The area where the "C" is was the hard spot -- you can see the crap job I did with the drill!

Slapped it onto the Gingery lathe, and it drilled, and bored, and turned, nice as you please......cut like buddah! :ddb:

So I'm kinda thinking along these lines:
