Hi Ian I was looking around the stores today and found some stainless steel drinking mugs at KMart at the Riccarton Mall. The mugs are made in India an priced $NZ4 each. These mugs are a close fit in the stainless steel coffee makers I have on hand. Hopefully these will be ideal parts for the hot cy...

Muffin trays have ten or a dozen "truncated conical shape" bits that might be worth experimenting with but I fear the available movement is inadequate for anything useful.

I have not seen any tubing and I dont know how a sheet material could be rolled into a tube without the seam being a problem.

Briscoes have rolled sheets of the stuff too, but I dont have an idea of how that could be used.

Yes Ian, Briscoes have quite a few bits too also the big red shed but I have not seen anything that would lend itself to becoming a rolling sock except for muffin trays but they do seem to be quite stiff. I will keep looking!

I keep looking at the silicon rubber bakeware in the shops hoping that one day I will see a shape begging to become a rolling sock seal.

Ian, I have found cheap(ish) cast iron plumbing end caps in various sizes which might be suitable candidates to become pistons!!

I am sorry if Ashburton is sending you problems! :big smile: What is the status of those boilers, is either of them suitable for use in other than a loco? So you dont think a big Stirling is easier than a tiny one? It must at least be easier to alter the bigger one. Right now I am trying to figure o...

Hi, this would be my first project in the world of Stirling engines. I am thinking a V type alpha would be a good start especially if I dont build it so small that precision engineering becomes a challenge. What I have in mind is a free standing wood burning stove with a vertical hot cylinder and wa...

Hi Ian, did I meet you on another site? I am at Ashburton and the workshop has everything I should need to keep me busy in retirement but I seem to spend all my time working/playing at the aviation museum. I hope to build a V type alpha standing on a wood burning stove, I am thinking that if I make ...

Hi, now I am the new guy! I am from New Zealand and looking at ideas for something interesting to make in my workshop and a Stirling engine would fit the bill!
