Marv-

Unfortunately in today's world, in some districts, you need to have your clearances along with a background check in order to enter a classroom.  This applies to the parents as well.  I live in the sticks and this is how our district operates. 

Frankly, in über-nanny state California, I was surprised too that they would allow anyone with a functioning mind into a classroom but this was a private school so perhaps they felt that education was more important than mindless, zero-tolerance BS.

I took my engine to the local Porsche and BMW dealers to show the boys. They went positively out of their minds with interest and appreciation, wanting the details of the inside parts, cranks, cams, etc.
It is a very rewarding experience, especially with the mechanics.

I carry breath-powered engines in my pocket when I visit technical purveyors, e.g., metal yards, tool stores, etc..

When I get the seemingly inevitable, "What are you making?" query, I whip them out and say, "Well, I build little engines."  It's amazing how many private stashes this simple act can unlimber, how many discounts and freebies magically appear.  They also work as a magic key to gain entry to the normally off-limit engine spaces in ships and locomotives.

Marv,
I don't recall seeing your breath-powered engines described anywhere. I assume they're wobblers. What is the approximate bore, and what materials do you prefer? Is there an issue with -ahem- saliva?

Neither is a wobbler.  One is the tilting piston valveless engine that saw a period of popularity on the Macbeth site...



and the other is a double-acting horizontal mill engine with piston valve...



Neither has needed a spit valve although, after too many years of smoking, I seldom run them for extended periods of time.  They can be run from a camera dust-blower bulb but people seem more impressed with the idea of an engine running off human power.

Thanks Marv. I'm glad I asked.

Thanks for the tip Marv, I must remember to put this little one in my pocket next time I go to the suppliers:

Ingenious Jim. I mean those of us that built them back during the craze over on the other site know how they work but seeing it like that in a glass tube add a whole new dimension to it. Well done and a nice looking engine as well.

Nice one Jim.  I don't believe I ever saw one of those before.

BTW, for those of you that missed the show, here's a link to the New England Model Engineering Society website:

http://www.neme-s.org/2015/Cabin_Fever_2015/cabin_fever_expo_2.htm

Errol Groff has photodocumented NAMES and Cabin Fever shows for years.  I think he photographs every engine on display and it's the best way to see the exhibits.  I went to the CF show and missed several of the engines that Errol photographed.

Cheers,
Phil
