Best Epoxy for...

I have an aluminum decorative casting, too thin to tap, that I need to
glue a mounting bolt to.

Loading, SHEAR, will be less than 4 pounds.

I have adequate room behind the casting to build up a nice fillet
around the bolt head.

What would you recommend?

Thanks!

I'm having brain cramps but recall seeing a demo at the hardware store
check-out counter. Was a 2 part epoxy that they glued a golf ball to the
neck of a pop bottle. Was good stuff. I used it a few times. There's also
some MRO products from Devcon
http://www.devcon.com/products/produ...Metal%20Repair

Some of these are so durable that they can be used to fix industrial pump
impellers.

hi, what about getting it welded ? i`ve gotten aliminium casting welded
before at local engineering place,..add a bit of weld then drill and tap
it ?

Clean, degrease, perhaps rough up a tad, and apply whatever epoxy is
handy - heck, hot glue might do it.

If you want to do it really well (or "best", as you start out with),
hunt up some Armstrong A-12, but that hardly seems like where you need
to go for the described use. It does work VERY well.

Rethinking your process. In descending order:

* Blind nut, or bolt from behind. Perhaps put the bolt through a hole
and glue from behind.

* Have a welding shop (or a friend with a TIG welder) weld a boss onto
your casting, drill & tap that.

* Get some aluminum soldering kit from a welding supply place and solder
the bolt on.

* JB weld.

There are products designed for just that purpose, consisting of an
aluminum powder combined with an epoxy. I used to use this to fix
extrusions (heat sinks) that had scratches and gouges. It looks like
aluminum, is machinable like aluminum, and holds well to the base metal.

If you need, I can see if I can find a maker/part number for you, I may
have some left on the shelf, but I'm not sure.

If you must glue, use a very good epoxy. Place a few drops in the area to be glued and sand it in
vigorously then place the nut or bold on the area and glue with a generous fillet.

I have had good results with Araldite two part epoxy for over 30 years.
Ciba-Gigy sold the adhesives to Huntsman, so now I purchase Huntsman
Fastweld 10.
A search of Araldite has a lot of hits but now they have so many products, I
don't know
what the original was.
So go with the Huntsman Fastweld 10 Rapid setting Epoxy structural
Adhesive.

Just don't try to have it anodized...
Over the years, we've had a few subcontractors that made an 'Oops' when
fabricating aluminum parts. Mostly the fault is holes drilled in the wrong
spots. Contractor filled them in either with either a weld or some filler
and milled them flat again. Barely noticeable if at all on incoming
inspection but when they were anodized, very noticeable. Acid etch attacked
the filler material much more readily and the result was unacceptable.

Jim - you might take a look at rec.crafts.metalworking. There was some
discussion about methods for epoxy & aluminum. Using sandpaper wet
with epoxy to clean the aluminum was most notable. Also, slow
curing resin rather than the quick type is reportedly stronger.
I made a shear test of Devcon's "2 ton epoxy" on yellow
pine glued to yellow pine that broke at 1200 psi (~2 minute delay).
Similar tests with polyester (waxed) indicate strength with aluminum at
2/3 that of yellow pine. Assuming the bolt head isn't microscopic,
you may have a little leeway.

Some good suggestions.

What about the one-shot, low-volume epoxy kits available as 'rear-view
mirror repair'. I'd try it on a test piece first. Maybe select and
machine the bolt-head for size and uniformity, first.

Easy to get, anyways.
