Please explain how I can make brass eccentrics with a Dremel and a needle
file...
I know I could just use ball-bearings with a large inner race. :)
A bit more info... I was thinking that it might be nifty to build a
compound Mallet engine using ruby running gear with roundhouse cylinders
for the low presure side. The problem with that is I can't see a way to
easily route the exhaust from a set of Ruby valves in both directions. If
I could get an honest link-styled valve motion on the Ruby, this could be
done. :)
Clear as mud?
Trot, the honestly curious, fox...
