Wonk,
Having such a long belt around the cone pulleys is a weak point but in
hindsight I think my main problem was the sharpness of my cutter. I was able
to cut 0.05" in 6061 a few days ago with no problem at all.
I have considered replacing my aluminum handwheel/flywheel with a steel one.
It connects to a 5/8" shaft that drives the chain to the bull wheel. The
heavier flywheel would add a lot of power to that initial contact of the
cutter to the part. I would probably want to pin the flywheel or add small
holes for the set screws since the force would be great. Worst case, I could
twist the 5/8" shaft. Not a big deal since it was just cut to length and has
only one flat on it.
But I'm not going to solve this "problem" of lack of power until I really
see it.
Rick

Rick,
Do you feel the modified drive train that you built for your machine might
have anything to do with how it works? I would think trying to solve the
belt slippage trouble might help, and maybe checking for drag in the
movement areas, and placement of the cutter?
I suspect you cannot compare a homebrew machine with a commercial machine,
due to the aluminum castings! I did not find my machine to be a problem but
then it was made mostly from ZA-12 alloy which added quite a bit of weight
and strength. I'm using wheelium to build my second machine so hopefully
that will work?
Cheers Wonk
