scotch weld 420 epoxy

[gwpercle]

JB Weld is a very good product. When you need something to do something and do it right do not use price as a measuring stick.

And whatever you do ... Do Not Get that fast setting stuff ... not enough working time and the quick-set makes a weaker bond than the original slow cure J-B Weld #8265S , twin tube , 4-6 hrs. set time ...15-24 hrs. cure time ... 5020 psi tensile strength .
Don't be fooled by $1, 000.00 government glue ...it don't work near as well.

With aircraft, it’s the certs that cost more than the actual product.

Pretty much, it has to be certified for use on aircraft which opens a whole can of worms. Things like conductivity, temperature ranges, burn certs, etc. Heck we even have a conductive epoxy to attach and bond static wicks to airframes that has enough silver metal in it there is no appreciable resistance on an ohmmeter. A little 1 ounce cup of the stuff is well above $1000. I have a few rolls of tape at work that are $600 a roll. And to boot, it all has an expiration date and one past it, not worth a plug nickel.

Aviation, its a different world!

the only thing that a 5 minute epoxy is good for is if you want to take the parts apart at a later date.

With most GOOD epoxy's or 'gun bedding' kits, 24 hours is the MINIMUM cure time. That is at 'room temperature' or about 70*F. My shop varies from 55* setback overnight to 65-70* when heated for work for 8 months, then air condition in for some. Warming, 100-140* can speed up cure, like interior of a vehicle in the sun, but I just prefer to wait the extra time. Time vs temperature are important for proper curing, that's just how chemical reactions work. I usually wait an extra day when using JB Weld or other epoxies to insure full cure. The short 'open' times of the 'quick-cures' keep me from even considering them.

Has anybody found a product that can handle heat? I have a sinker mold that I need to modify. It was a split shot mould that I want to cast slingshot ammo for the grandkids.
I would welcome advise from any that may have tried this before.

Have cast 45 caliber round ball and used for sling shot ammo. Really works great. For less lethal and grand kids I might look for 32- 35 caliber . have fun.

I like a 36 RB (.350) for use with my wrist Rocket. The garden rabbits hate 'em.

For sling shot ammo Im thinking one of lees buckshot moulds would work well. And youll get 18 pellets a pour.

My sling shot ammo mold is a .45 cal round ball 2 cavity from lyman.

But I agree with country gent that one of the Lee buckshot molds would IMO work pretty well.
