Hot Air Engine

As an alternative to you might like to try 7-zip as it's opensource (free) and handles most archive types (zip rar arj tar etc etc) or UnzipThemAll which is freeware (I think WinRar is shareware).

Yeah, I'm not expecting the same performance (there's a nifty half-size version of this fan I've seen pictures of that I'd like to build someday), just checking that there's not some magic ratio of hot side to cold side that needs to be allowed for.

I built a half-scale Moriya, using Senft's full-size drawings as a guide. It was all very straightforward. I rounded some values, such as 7/8-inch to a full inch, etc.

Some things did not scale down very well, such as the crank throws, so I used Jerry Howell's mini-fan drawings for the crankshaft and displacer connecting rod.

Here's the link to my Mini-Mo.
