Just a note when trying to run one of these banded vee belts....
As for as multi-vee pulleys, they can have different vee spacings.
There are "V" belt pulleys, there are "L" belt pulleys, there are "A"
belt pulleys, (and "B" and J rib" and on and on").
But be aware the 3 that I first mention look almost the same.
Yes "V" is a series of belt, not the same as "L" and "A".
Anyhow, if you were to buy a commercially available pulley
(or sheave or whatever), for multiple belts, there are 3 different
spacings available for the seemingly same size belt. And to
add complication, they sell a combination "A/B" pulley (multi-
vee) that is actually the spacing of the "B" series of belts
(Because "B" is larger, and it has to be). This to reduce
inventory. (Just like phasing out match sets of belts).
I bought a 5 belt pulley for my 17" Colchester lathe, to
get a taper lock series, and get away from the shaft and
key type that had fretted tight to the motor shaft.
I ordered an "A/B" unit, spacing too large to match the
headstock pulley. So I got out the CAD models from
their web site (B&B mfg, as I recall). I downloaded models
of their "A/B" pulley, their "L" pulley, and their "V" pulley.
I also double checked the CAD models from Browning
and McMaster Carr. They all seemed to be 99% the same.
Anyhow, it turns out, I needed a 5 belt "V" pulley. NOT
the others mentioned. The "L" spacing between the vee's
was about 1/16" more. The "A/B" (really a "B") spacing
was about 1/8" more. This was a small problem for matching
multiple separate belts on pulleys, but mismatched pulleys
would be a NOT-GO for banded belts.
So I know this was a babbit hole of pulleys, but just thought
I would mention it, in case you start ordering belts and nothing
is fitting up. I am an engineer, and I really feel like I should have
known this stuff about pulleys and belts. But I am smarter now
having went through finding the answers to replacing my lathe
motor pulley. Live and learn, and hope I helped someone here.
