How you all going?

Would somone be kind enough to tell me what exactly is JB weld. We don't have anything called JB Weld in Australia.

Maybe if I can get an idea what its made of and it's intended uses I mite be able to get a substitute here in Australia.
If not which knife supplies sells it?

If you can't find it, I'm sure one of us can get a tube to you. I just checked and air shipping would only be about $8 from Canada.

:rolleyes: Geeze, it would cost me more than that to send it to British Columbia - the next province west of us - about three hours away.

As mentioned above, JB weld is an epoxy, with a dark grey color when cured. It is however a very good epoxy, and very reliable. I've had spotty results with many other epoxies where some times it's hit or miss with the tubes you get at the hardware store, but I've never had a bad batch of JB weld. It's good stuff, just not so usefull on full tang knives because of the color.
 
JB Weld is a filled epoxy. Go to an auto parts store and see what they have similar to it. It is a thick grey two part epoxy that dries hard to something that resembles grey pot metal. Another brand that is similar was called PC-7. I have seen other types used for repairing cracked metal.
BTW, it is gray to the Americans, and grey to those who speak the Queen's English.

"Will JB Weld work on steel plated with nickel or zinc?"
Personally I've never used it but one ol timer once told me " it will glue Vaseline to a fish"! lol
 
Basic epoxies can be modified for setup time and strength through admixtures. Most standard epoxies are types of thermosetting plastics, heat produced by chemical reaction will cause polymerization. Thin layers of epoxy can achieve far greater strength with a heat lamp to help out. Filled epoxies generally use carbon black for primary structural enhancement, waterglass also used. Most all plastics have some form of additives, average 23% total weight is additives. The flexible magnet strips are plastic with 90% additives (barium ferrite-filled ethylene-vinyl acetate). Other potential fillers are kaolin, mica, talc, glass spheres, MgO, graphite, wood flour, starch, sand. Fibers could be glass, carbon, or aramide fibers.
 
Fellows, this is an eight year old thread ... Start a new thread if you need to, but there is no need to bring back this subject.
