Re: Sterling Diaphragm Engine

Thanks Kong. I only hope it will work! I have nearly finished the radiator cooler for it and just finished readapting a gear pump for the water pump.The ratio for the drive will be 3:1 gear driven.

Re: Sterling Diaphragm Engine

Have finished the new Displacer complete with its stainless steel wool. It seems to fit snugly in the displacer tube without too much friction.
When the brass stock arrives will then finish the crank and fire her up. Will post photos when she is running in a couple of weeks I hope.

Re: Sterling Diaphragm Engine

Redoing my displacer for the engine. Looks a bit rough but it is only a cage to hold the stainless steel wool. The one I had made earlier was made from two inverted tuna tins but had to much side clearance which was going to be a lot of dead space, hence, the redesign. Has anyone else used this cage...

Re: Engine vacuum

Thanks for that Ian. Yep just out of Cairns but a long way from NZ.
Brass is a product that I still can get. Thanks for putting me onto the right stuff as I have had a lot of problems using aluminium.

Re: Sterling Diaphragm Engine

Whoops! looks like there will be no photos or attachments then. I am into making the crankshaft now as all the rest is basically done. Painted even. The crank is going to be difficult as I it is a beta Sterling and I am thinking of using a bell crank. Can't find an actual formula for it so I am goin...
