I have been inspired by the set of videos. I wanted to ask if you sleeve the engines or run aluminum cylinders and if so, do you run rings and what they are made of and what are the pistons made of?

[myfordboy]

@Gregkret The cylinders have a cast iron liner. I use cast iron pistons with no rings. The cylinder is lapped to a good fit with the piston. I find the engine will run longer on the miss strokes with no rings, less friction. I am not looking for max power but a slow running engine.

I thought you would have cylinder in the headstock spindle.

Why reverse it ? Is this common?

Been searching for engine boring vids. Great stuff.

The casting is much too large to fit in my headstock. Even if it would fit, the boring tool would be very long and springy. Doing it this way there is less tool overhang.

is this engine finished? if so how is the rest of it made, the crank, rod, etc.? Could we see an updated video?

[myfordboy]

I was going to wait until the engine was fully finished before showing it but I have uploaded another video of the progress so far.

These are some really great parts you are turning out! I loved your homemade shime supporting the workpiece.

I guess there really is more then one way to skin a cat. Use what's available, Good job!!!

any tips for making stirling power pistons/cylinders such as what material? have a colchester and a small mill. can they be made from brass or ali? hope you can help. cheers

@myfordboy

Great stuff, although on the related videos it shows a Harley engine being bored with headstock.

Guess it can be either way right? Just preference.
