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?


According to the late Johnny Cash:


"The One On The Right Is On The Left"

There once was a musical troupe
A pickin' singin' folk group
They sang the mountain ballads
And the folk songs of our land

They were long on musical ability
Folks thought they would go far
But political incompatibility led to their downfall

Well, the one on the right was on the left
And the one in the middle was on the right
And the one on the left was in the middle
And the guy in the rear was a Methodist

This musical aggregation toured the entire nation
Singing the traditional ballads
And the folk songs of our land
They performed with great virtuosity
And soon they were the rage
But political animosity prevailed upon the stage

Well, the one on the right was on the left
And the one in the middle was on the right
And the one on the left was in the middle
And the guy in the rear burned his driver's license

Well the curtain had ascended
A hush fell on the crowd
As thousands there were gathered to hear The folk songs of our land
But they took their politics seriously
And that night at the concert hall
As the audience watched deliriously
They had a free-for-all

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 guy in the rear, said, "Oh dear"

Now this should be a lesson if you plan to start a folk group
Don't go mixin' politics with the folk songs of our land
Just work on harmony and diction
Play your banjo well
And if you have political convictions keep them to yourself

Now, the one on the left works in a bank
And the one in the middle drives a truck
The one on the right's an all-night deejay
And the guy in the rear.. got drafted



There are a couple links on YouTube for the song:
