Oh I'm using the original drive mechanism , just the belt has

Flip it over, Terry. That'll relieve that little misstep.

I seldom tighten the belt that much , no need to . I got really
tired of having to regrind cutters because the belt slipped in a
heavy cut and the cutter welded to the work .

I can see where that would be counterproductive.


I've used this belt with both sides against the
pulleys , not a whole lot of difference .

That's interesting. Are you running on cogs or smooth pulleys?


Smooth flat pulleys , and no cogs on the belt , just lengthwise ribs

My Crom, am I that far removed from automotive work that I've
forgotten what a serpentine belt looks like? thud My last two
vehicles have been new, and I've had very little to do under the
hood
since then except a few belts per decade since 1991. Astounding.
Har!


doesn't need to be all that tight unless I'm making hoggin' cuts to
remove
stock quickly .


Make a sawtooth cutter for less resistance? (Juuuust kidding.)


I really need to rebuild the reversing tumbler and stud gear
assemblies .
Not only are the bushings worn , but the gear teeth have thinned
enough to
detect with the naked eye . That 150 bucks I spent on a 16dp


(Hadda look DP up: Diametral Pitch, right?
"The Diametral Pitch of a spur gear is equal to the Pitch Diameter
divided by the number of teeth on the gear. The Diametral Pitch of
a
spur gear may also be calculated by adding 2 to the number of teeth
on
the gear, and dividing that total by the Outside Diameter of the
gear.")


gear cutter set
is going to save me like a thousand on parts for that .


That's the great part about knowing how to build your own stuff,
isn't
it? My life wouldn't be -nearly- as interesting if I wasn't a
full-blown tool user. How do the tool-fearing folks manage? Wow!


They probably wonder why we'd want anything we can't just buy.

Browning had relatively reasonable replacements for the munged gears
on my ex-trade school South Bend.
