[SEL] What glue to use??

[Michael P. Koryciak]

I have a couple of different ideas on what to use for gluing the v-belts 
in the grooves around the circumference of the pulley.

1: First, let me say that the idea of gluing v-belts into pulley 
grooves, in order to use a flat belt is absolute genius! I love the 
idea. Are you going to use the common auto/light truck "MicroGroove" 
belt? I've read that they are supremely durable,and get the most common 
size by going to a junkyard and getting one off an old Chevy.The most 
popular size belts cost the least. Do a google for "Gates Drive Belts" 
and see what their equivalent stock number is....I hear they make the 
best serpentine belts.

2:My first choice for glue is "JB Weld"....it has metal (Steel?) 
Particles suspended in it, it's some sort of epoxy,I've used it to fix 
leaking Gas tanks on cars. Just make sure you wait at least the 
recommended time or more before putting on that flat belt.

You can get large tubes of this 2-part glue at Sam's,Costco,and Home 
depot....cost is about $2 to $3 .

3: There's a poly-urethane glue out called "Gorilla Glue"....it's plenty 
strong, but it is quite expensive....also once it is opened, if you 
don't seal the nozzle back right away the whole thing will harden. 
Moisture in the air cures it.There's also the same type of glue made by 
Elmer's   (The old 'glue-all' product)  called "Ultimate glue" that 
costs a little less than the Gorilla.

If it were me, I'd take the  V belt(s)  and  the pulley and (Outside!) 
wipe them down with Lacquer thinner, Acetone, or Mineral spirits; let dry.

Then I'd scuff up the belts on the "V" side, and the pulleys a bit, too.

I'd cut the "V" belt at a 45 degree angle,put a small spot of "Crazy 
Glue" on the belt inner side, and press it into the pulley until it 
holds.Then I'd Put JB Weld on the rest of the groove(s) with a small 
brush, and put the belt under tension and roll it around until it meets 
the beginning.Cut it off a bit large, then progressively smaller until 
you get a good fit.

Then I'd duct-tape the whole "V" until it sat for the required time.
I'd do one "V" at a time.

Once cured, good luck getting the "V" Belts off!
