So I'm goofing around with pneumatics--bouught the bits 'n pieces over the years
thinking that i was going to do something 'wonderful' with 'em.

Well, since LOR couldn't get moving properly, and I couldn't get the GBC
'vacuu-sucker' going properly, the pneumatics were relegated to the bottom shelf

I went over to CSSOH's page and had a gander at the 2, 3, 4, etc cylinder

Oh My Goodness--pure 'old style' technic and you have somethign beautiful!!!   Think I'll build one for the hobby show...

Anyway, distractions aside, I'm trying to figure out how to incorporate a very
tiny yet 'has lots of momentum' flywheel into the gizmo I'm trying to develop.

Sure I could add metal washers and stuff, but that's not 'LEGO' pure...

Anyway, having fun with it and hopefully i'll have somethign for the hobby
show...
