Got a broken. part for a saw that they don't make parts for anymore.Wondering if I use JB just to hold it together can I use it again for more strength?
If so how to or is it necessary to prepare the JB surface for the additional JB
just

a picture would be good

also several types of JB weld form putty with metal imbedded as well as several other 2 part epoxy options

bonding something into it to strength the joint may help also

clean of any dirt , oil or wax for surface prep.

degreased and a little sanding isn't a bad idea

Jb weld is crap! It didn't work on my22 rifle I let it dry for 2 days when I shot the rifle it came off.

I've "fixed" quite a few things through the years with JB weld

AKA
Clean the surface free of foreign materials and then rough it up with a coarse grit sandpaper. Without pictures that's all I can help with.

I am a JB weld fan!!!!.....jk

what was the application , bedding or holding a stock

it is actually stronger psi than most bedding epoxy

but prep and application is everything and again about 12 kinds of JB weld

What is he wanting to fix?? Can it be welded and ground down??

It was holding the ring around the gun stock.

Hitachi slide compound miter saw
currently held together with superglue
Considering covering crack with JB and then partially filling void with JB

Parts

I’d say fix it. JB has a place, but I dont believe its that

What make saw ? If a Stihl , There’s a retired dealer in my town that has parts for older saws, he ships all over the country.

I believe this is called the right side fence.

About 10 years ago I busted a fifty cent piece sized hole in the crank case of a 70hp Yamaha outboard. I carefully degreased (brake cleaner) and sanded, then degreased again, both around the hole, and the piece that busted out. JB welded it back in place. It's still running fine.

Before and after pictures of the repair. The red plastic pieces were glued on first so that I could use them as handles when setting the broken piece in place. I cut them off after everything had cured.



BTW, the piece broke out due to an internal failure of the oil injection pump worm gear. After that I removed the auto oil injection mechanisms from all my two-stroke outboards, and now pre-mix.

we used alot of Devcon steel poxy when i worked in the mine. It was good stuff

I would cut a peice of threaded rod that will lay in that space , drill a 3-4 little holes that allow finishing nails to go in and lay across that rod , then with your grid of metal and it all degreased fill that space with epoxy and let it set for a few days. then trim the nails flush with a grinder on the outside

I had some small holes on the oil pan of my old Honda Civic. Drained the oil, cleaned it up, put the JB Weld to it. Drove it another four years. Patched and repaired a lot of things with it.

I would drill some small holes along each side of the break. So you can work the weld through them to make more of a solid bond by connecting the weld to itself on each side.

good stuff ,fixed 350 chev block with crack ,

Had you ever let it freeze? Because once it gets frozen, you have to throw it away.

Sure seems possible. I would laminate along the side of the crack with something like a piece of aluminum trimmed to fit. Bonding the scrap over the crack to reinforce.
