JB WELD FIXES CRACKED CYLINDER heads

There are persistent rumors that the primary component in JB Weld is magic. This two-part epoxy that you would typically discover on a shelf next to your fundamental 5-minute epoxy, Titebond, different cyanoacrylates, as well as Gorilla glue is somehow different. stories of ‘some guy’ in the Yukon utilizing JB Weld on a cracked engine block abound. These stories are of program satisfied with skepticism.

Now, finally, we have evidence you can utilize JB Weld to repair an engine. [Project Farm] over on YouTube provided it the supreme test: he took the cylinder head off a lawnmower, took a grinder to the head, as well as patched the hole with JB Weld. The head had great compression, as well as the engine really ran for 20 minutes before the test was concluded.

If this were a test of a field repair, it would be a test of an incredibly crappy field repair. [Project Farm] made no attempt to guarantee the piston didn’t make get in touch with with the blob of JB Weld, as well as in fact, there was some small knocking from the piston tapping against a blob of epoxy. Still, this repair work worked.

While this serves as proof of the feasibility of repairing an engine block with JB Weld, there is one supreme test of JB Weld epoxy: develop an engine out of it. For years, I’ve been casting my leftover JB Weld into a little square plastic container. In a few much more years, I’ll have a block of JB Weld ‘stock’, big sufficient to device the parts for a little (.049 cc) glow engine, like what you would discover in ye olde tymie model planes as well as cars. will it work? I have no idea, however now I can’t wait to discover out.
