JB Weld vs JB Weld quick

I have recently read a couple of references in Stunt News about not using the quick cure JB Weld. Is there that much of a difference in strength?
I've read other references that say the only difference between quick and slow epoxies is the cure time.
I have not yet experienced a failed epoxy joint but it may be because I use too much.
It must happen otherwise it wouldn't be mentioned.

Your experiences?

It has been my experience that the quick cure epoxies don't make as strong a joint as the slow cure ones.

Hi, George,
I like the JB Weld, and no longer solder on my control systems. Tried the 5-minute version, found it inferior in strength and workability. Will never use it again. FWIW.

Where can I buy JBWeld in Australia ?
I live in the Eastern suburb of Belgrave, Melbourne....
Any Aussies know ?

If you can't' find it down there, we can get it and ship it to you.

Dave,
Lacking "JB-Weld" you might like to try a product called "PC-7 Epoxy Putty". Our local tool outlet carries it. Reads like JB-Weld to some degree. Bonds everything to everything kinda' thing. Not sure of the temp range for operations as a boost port blocking medium but it may work. Could be for sale in your neck of the woods. PC-7 Inc. market a range of epoxy repair products for wood and everything else. Worth a look see perhaps. JB-Weld is carried here in the automotive repair section of most stores that do stock it.

Back to topic: I've used both JB-Weld, and JB-Quick for arrow shaft control system assembly. Like them both. Word to the wise though. When it's says "JB-Quick", you'd better be on your toes and have your parts ready to go like "right now". The "Quick" kicks in very short order. So have all your ducks in a row before you mix a batch and work fast to get a wet assembly, then let it kick.

Dave,

You can buy JB Weld at K-Mart in Stud Park Rowville.

It is in the section with all the glue and general tools.

I live in Ferntree Gully, Melbourne... that's how I know.

Many thanks to all for advice, especially Peter, I finally got to K-Mart and got the last one they had.

Ferntree Gully is really a place?

K Mart has it in Hornsby. Can't help on Melbourne sources but I'd start at K Mart.

I am using jbweld to hold some brass tubes for muffler mounts onto old fox 35 stunts. Right now the jury is still out on this one because I've had two fail and two that are still holding. it maybe the brass needs better prep but the tubes were sanded to give a fresk clean surface.
Possibly it's from engine vibration, and oh yeah, running into the ground.
Jb weld is great stuff. A tube of this will last a long time

I used JB Weld to glue a couple of aluminum tubes to the side of an old Fox 40.. Lasted the first flight and one of them let go. It stuck to the tubing but pulled off the engine. I scored both sides of the exhaust with a file and cleaned it with acetone.

When I re-glued the tubes I put a strap around the back of the engine, all the tubes are doing is aligning the bolts so I can put the muffler on after the cowl.

If used within it's limits it's great stuff..

I haven't found JB Weld, strictly speaking, here yet, but I've seen at least 2 or 3 brands of steel-filled epoxy in brands such as Duro, Devcon, Araldite and Bostik. Both slow-cure and 5 minute. All the hardware stores carry them. Better to test before using somewhere important, of course..

I remember an article in the sunday paper years ago that said the reason JB Weld worked so well is that NO compromise was made in the search for the epoxy. The materials are very expensive but the original formila is still used. Seems the inventor has died and his wife was still running the co. because although a lot of people wanted to buy the co. none would sign up to not EVER change the formula. Nice to see something like that once in awhile.

I have been using Marine Tex for years it seems to set up a lot harder then JB and does not get soft in high heat areas like JB.
