Jon Cole Posted November 21, 2011 Posted November 21, 2011 OMG. OMG. omg!!! My jaw fell off. My eye popped out. Impressed... would be an understatement!
Harry P. Posted November 21, 2011 Posted November 21, 2011 Yeah, that's some impressive machining work, but it doesn't really "work"... I mean, it doesn't actually run on gas. He made a model with movable internals. Very impressive, like I said... but it's not like the guy who made the 1/3 scale Ferrari that actually ran!
Greg Myers Posted November 21, 2011 Author Posted November 21, 2011 (edited) Harry, how many of your models actually "RUN" ? Edited November 21, 2011 by Greg Myers
Scale-Master Posted November 21, 2011 Posted November 21, 2011 I'm with Harry on this. Impressive, but an air engine is not in the same class as an internal combustion engine. I don't need to have built any running engines to share that viewpoint do I?
LAone Posted November 21, 2011 Posted November 21, 2011 holy smokes! that is pretty cool. sooo much patience to make all those parts.
Chuck Most Posted November 21, 2011 Posted November 21, 2011 Running or not, still pretty impressive.
Greg Myers Posted November 21, 2011 Author Posted November 21, 2011 (edited) Take your pick. They all "RUN". http://www.craftsman...om/KnappCol.htm In my original post I simply felt it was amazing just to see how it was built, and thought everyone else here would too.I taught industrial arts in high school for many years and worked in an aerospace machine shop as well. This still impresses me. "Running" or not. A work or art. Edited November 21, 2011 by Greg Myers
Harry P. Posted November 21, 2011 Posted November 21, 2011 I agree it's an example of impressive craftsmanship. But it's not a "real" running engine. That's not a knock on the guy... just an "FYI" in case anyone thought this thing was an operational internal combustion engine.
crazyjim Posted November 21, 2011 Posted November 21, 2011 I think it's fantastic! I want to see the car that it's going in.
Modelmartin Posted November 22, 2011 Posted November 22, 2011 I was fascinated by the engine architecture. A V-12 with twin cams and overhead valves and separate cylinders. It seems like a WW1 era fighter plane engine. Obviously it is a great peice of worksmanship but not my cup of tea.
Scale-Master Posted November 22, 2011 Posted November 22, 2011 I too thought it looked similar to an aircraft engine. But then again, it does run on air... I know, that's bad. And I also agree, the workmanship is very nice and the fact it is "just" an air engine does not take away from the beautiful work. If I wasn't wasting so much time on model cars, I can see myself making one.
Danno Posted November 22, 2011 Posted November 22, 2011 Just how big is a 1/25 scale molecule of fuel, anyway? I'm trying to set my 1/25 scale jets.
RodneyBad Posted November 22, 2011 Posted November 22, 2011 WOW!! simply amazing.. Thanks Harry, I was wondering how it was runnin on fuel now I know it was air powered.. I was waiting to hear the exhaust. Still, Very Incredible workmanship.
Joe Handley Posted November 22, 2011 Posted November 22, 2011 Don't care what powers that motor, that was pretty cool! Aren't there companies trying to develop these air engines for 1/1 use? Don't ask me how well that's going to work for any kind of distance, it might take a huge air tank for any distance, But I'm not that familiar with the tech.
Chuck Most Posted November 22, 2011 Posted November 22, 2011 Unless you had an on-board compressor of some kind, maybe driven off a road wheel. Something to keep the tank pressurized as you drove. LIke OPEC's ever gonna let THAT happen.
Joe Handley Posted November 22, 2011 Posted November 22, 2011 (edited) AirHogs had some toy planes out in the late 90's that worked that way and motor wise, they ran pretty good for a tiny, clear plastic, single cylinder , backwards air compressor. If you had one fully aired up and just let it loose (it had no obvious form of mechanical throttle), they would try to pull themselves out of your hand if you didn't have a good enough grip on them and had a pretty aggressive sounding "exhaust note" (sorry, don't even know what that should be called) that sounded a bit "chopperish"! I think to make a street car out of the concept would require a car about the size of a Geo or Nash Metro with an insanely aerodynamic body and as mechanically efficent as possible, with the biggest airtank(s) that will fit under it.

FASTBACK340 Posted November 22, 2011 Posted November 22, 2011 Saw this at the Garlits Museum a few years ago.....
Scale-Master Posted November 22, 2011 Posted November 22, 2011 Tata Motors in India had announced a compressed air car about two years ago. Seemed plausible, but like hydrogen, the infrastructure of air compression stations would need to exist before they could be a reality. As I recall it was in the range of 4500 PSI being stored in the "fuel" tanks. Your Craftsman compressor is not going to do the job, so it's not like you could "plug in" or "pump up" at home at all.
