[TheForge] Speaking of hammers

Fri Apr 16 19:40:01 2004

I agree, Mark did the work and deserves to get paid for his plans.

I've seen a couple sketches of Mark Krause's control scheme and heard about
some of the problems he's had with heat and scaling it up. Basically his
valve scheme has the compressor piston compressing air on both strokes at
idle and venting excess.

I'm using the Massey valving scheme which only compresses air on one stroke
at idle and doesn't produce much excess compressed air to vent. It shouldn't
suffer from heat buildup and should scale up with minimal hassle.

Like I say, I'm pretty firmly commited to the Massey valve scheme, I just
want to know how far to carry it. The poll now stands at: 0 Yea - 1 Nay

Thanks Steve.
