I'm thinking of running three timing belts side by side on one pair of
pulleys. Do you think I can get away with just bumpers on the outside
edge
of the pulley and three belts running beside each other? Or will they
end
up climbing on top of each other? In other words do I need belt guide
bumpers for each belt? (hard to do in the space available - only room
for
two belts then)
Yes, as soon as one belt got a bit of slack in it, it would flip
sideways and try to ride the others. That would do one of two things:
snap the loose belt or cause the adjuster to slip.

That's why triple-belted compressors have v-belts and triple pulleys,
for some separation. Watch a large compressor belt setup and you'll
see them flap at each other.


.200 pitch by 3/8 wide belt FWIW. I thought I had seen 1" wide belting
in
.200 pitch when I started this design. Now, no can find.
I like the way you think, always did! But, even I wouldn't do that.
You just liked the part about the belts jumping each other, didn't
you, Tawm?

I like the political implications, one on the left, one on the right and one
in the middle. Which one wins?



Well the one on the right was on the bottom, And the one in the middle
was on the top, And the one on the left got a broken arm, And the one in
the rear said, "OH Dear"
