Lots of good info in this post. I still like the idea of this concept. I know that it might be hard to get things to the proper weight and size though. How much HP do you guys think would be needed for such a project? The other thing that I have thought about is a Stirling type engine, but...

In response to the EAS. Someone had way too much time on their hands. :o BTW, This is a great thread!! ;D Greebe

Tin-- I got it now. I hadn't looked all the way through the plans yet. ::) Thanks Greebe

Cool. Perhaps I will go with an aluminum cylinder and a brass piston. The aluminum is cheaper anyhow. Thanks Greebe

Kermit-- Do you have any links on info for flash tube boilers? Safety is obviously a concern. I do not want anything blowing up. :o Richard-- Yes, I would be very interested in that article. That would be awesome if you could scan it for me, I would be very grateful. Any info and plans would...

Thanks for the replies. I guess my concept is one that could be portable in the sense that it would be small enough to easily transport via ATV, snowmachine, or a SuperCub(small plane), but have the power to do useful tasks. If I were using a gas engine it would probably be in the 5-hp. range...

Just curious as to what the most efficient steam engine design is. I know this depends on the usage of the engine, but overall what would be the most efficient? The reason that I ask is because I am interested in possibly building a mid sized steam engine that could act as a PTO for running...

Dennis-- Very nice looking engine. Is it all aluminum and brass except for the drive shaft? I like the looks of it. I don't know if I understand the rotary valve. The drawing makes it look like it the two slits are not connected. How does the intake and exhaust get to and from the cylinder...

I haven't built any steam engines but am planning on putting together one of the Launch style steam engines like in my post here:http://www.homemodelenginemachinist.com/index.php?topic=8083.0 One of the questions I have is about the piston and cylinder materials. Can they both be brass or...

Thanks for the responses. I figure it is time for me to make one of these engines. Tin-- Thanks for the link to the plans. That is a much better descriptive than the PM article. Ironman-- Your engine looks very nice. I think I will just order the stock that I don't have and build from scratch...

I found a box of Popular Mechanics magazines from the 50's up to the late 70's in the attic of my mother house when she bought it in 1993. As a mechanically inclined 13 year old, I was thrilled with my find. The one issue that I found that really caught my attention was the Feb 1973 issue. This...
