Hello all,
I had done some experiments with the rotating weights inside clear tube, here is the link to youtube vid of the setup.
http://www.youtube.com/watch?v=2-DzKKHEUA0I couldn't come up with steel balls big enough to photograph while rotating, (Outdoor world was out of large sling shot ammo) So I opted for marbles, they were pretty heavy and easily photographed..
I got the idea from the Centramatic web site in thier How it works section.
I only got to do a few tests, while tapeing BIG nuts to the inside of the flwheel, for weight, I decided this was a little dangerious, then trying to calculate the MPH of a flung nut.
Decided to get some modeling clay instead, but then decided to tear the engine down like everyone said was the right thing to do.
now it's in pieces and working on plan C ( a and b failed) to remove Gibb keys.
I did buy 4 tractor trailor balancing discs, the tube is easily removed from the sheet metal in the middle, leaving only the tube.
They are 17" diameter and I planned on lashing them on the flywheels.
one concern I do have as to the effectiveness in this application is the constasnt acceleration and deceleration on each stroke, this may keep the shot moving to much to be effective,
There is an old time tire store near here that has the clamp on wheel balancer with the internal moving weights,
fabrication of an adaptor with enough standoff to clear the end of the crank might be tedious but doable.
I would prefer this to my moving balls idea.
although they may respond to varing balance with changing load??
regards
Bob
