I ordered a segmented belt from HF and I got it today, noting once again, to my amazement, that the product is manufactured in….......................Italy! Wow.

Anyway, I gave no prior thought to the fact that the motor sheave is a wide, flat one, so there’s less surface of the belt riding on it, just the little tab ends.

It does indeed run smoother but I’m wondering if anyone has any long term learning that might affect my relationship with that tool and its power transmission system.

Kindly,

Lee

Well, I have a couple of machines that run very fast and
use flat belts. I think at a certain speed flat belts
work best, but I doubt you’ll be running that
shaper spindle so fast.

These are designed for a v-belt profile, with the spindle taking a regular sheave and, because the spindle moves up and down, the belt rides on a sheave that is flat and about 1 1/4 wide on the motor. A v-belt works well because there’s enough contact on both sheaves.

The segmented belt, not so much on the motor sheave.

I haven’t run any stock but it sure runs smoother and sweeter with the segmented belt.

Kindly,

Lee
