Huxtable Hot Air Engine.
Stilldrillin:
I don`t usually make engines, but I own and repair quite a few...... My latest engine arrived a few days ago.
Several members have asked questions. I`ll try to answer them...... :thumbup:
This is it....... http://www.olds.com.au/stirling/
A heavy, awkward lump of Australian engineering, compared to the toys I`m used to.....
The little thumbscrew on top locates the cylinder into position. Allowing it to be slid off, to demonstrate the action......
Removing 1 nut at the rear of the crankthrow, allows all the action to be removed......
The only "fault" I have found with it, the little end bearing had too much clearance (for me), and allowed a "tick" when running.
I repaired this by unscrewing the hexagon "gland nut" (no packing), from inside the piston skirt, and bushing the conrod back to the 3.5mm dia of the pin pressed into one of it`s hexagon faces.

Thanks very much, David! That tells the story well.
The hot end cap is silver brazed on, is that right?
