tightness of Gilmer belt

Post by Gene Howe »

From reading what I could find I've not found how to adjust the Gilmer belt tightness. I seem to recall that at slow speed setting, it should deflect 1/8" or less. Mine deflects considerably more.
Can anyone help?
Thanks.

I follow the instructions from Shopsmith (http://www.shopsmith.com/ownersite/prod ... cement.pdf) and turn the eccentric til it "screams" and then back off until it stops. I never bothered to look at how much play I had in the belt when I was done.

Exactly what I needed. Looked all over for just this info. I couldn't find it.
Thanks a bunch, Rob.

Rob,
Though I couldn't get it to squeal, I got it tight. The eccentric was pretty hard turning. When I opened it up the slot was between 8:00 and 9:00. Moved it to just past 9:00.
Your assistance really helped. Thanks very much.
Now back to resawing mesquite.

What is causing the 'screeching'? The clutch???? Belt nub sides against pulley nub sides?

GENE: The tension should not vary with the speed control setting.

JPG, When the eccentric cam is turned clockwise, it tightens the grooved belt. The squeal would be slippage of that belt, I'd assume. I never got it to squeal.
True, the speed control setting does not affect that belt's tension.
