Bored 3/4" first, then mounted on the conveniently sized 3/4" center spindle of the faceplate. Bolted the dog through the slot, and started turning the end...

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!

It is hard to believe the piece you took out of the stove is the same piece holding the cylinder right now.

Great start!

Well Eric, as I always say, rusty is only skin deep!  :dremel:


....was happy to discover you could anneal chilled cast iron, btw. I didn't know that. Could solve a lot of problems.

Only half an idea but i am thinking about air driven at the moment and like you vtstream I am making it up as I go along. So far I have the beginnings of a piston.
Turns out this life c**p is just one big distraction from death but a good one. For the love of god dont give yourself time to think.
