Here is a 1.5 minute video of Lucy running. It was built by a student
who had never operated machine tools, requiring about 24 hours of
instruction time for him to complete. Edward G. Warren provided the
.mov is a QuickTime movie, dude... Available for Wintel boxen, but an
Apple product. Unlike Microsoft, Apple has a long reputation for being
practically "malware-proof". No need for that Active-X crap. Just
7500/G4@350, OS 9.1, QT 4.something played it just fine.
I'm left wondering how long the little booger will last, though... Seems
to be pretty high RPM (comparatively speaking) and the way the cylinder
"jumps around", seemingly at random, doesn't bode well for having it
survive more than a few runs of a few minutes each. Looks to me like a
recipe for a cylinder being shaved *MIGHTY* thin in a big hurry.
I've been trying to figure out what material the piston/rod is, and
what, if any, lubrication system it has. Nothing was blatantly visible
for oiling, but...
Still, a neat little toy :)
So you have an upgrade too? I'm running a 9600/G3-400, fully loaded. No need to
upgrade until my apps get too outdated.
The engine appears to be of the type using a ported rocking cylinder and no
wrist pin. The randomness looks like it's from the camera (wagon wheels turning
Well its a great looking little engine.
Good work to the student.
I don't know what it takes to view it but it shows up fine on 7 year
oldd 300 dollar when new Emachine. That has never been damaged by
anything over the internet. Of course I don't use outlook.
I'll try to respond in order of comment:
-Lennie-It is quicktime. I'm sorry it didn't run for you.
-Statics-Thanks for pointing out the quicktime.
-Shiver-Me-Timbers-The .mov was built on a new mac by one of our web
-GTO69RA4-Your mac is my hero. :)
-Don Bruder-We had the air cranked up to 20psi on that run. It has
run at 12psi for over an hour at a stretch. Student has since
graduated but he successfully demo'd it for an employer. The cylinder
and block are lexan. Rod is aluminum and doubles as piston. Just
luck for lube...It actually didn't heat up noticeably. Biggest
problem was the spring rate on side opposite cylinder block. Had to
seal cylinder to block but friction was a killer.
-GTO69RA4-You are absolutely correct about the design and randomness.
-Don Bruder-Thanks for locating the apps. I should have posted those
on the site :(
-Lennie-I'm useless for your apps problem. Sorry
-Garry-Thank you for the encouragement. I'll pass the comment to the
This was a nice "take home" for a BS in Physics student.
