Not for this application, but perhaps of interest still:

Loctite Depend 330 is a quick setting two part, (goop and primer) acrylic adhesive that yields over 2000 psi shear. Set's in a minute and then grows strength. Advantage, unlike most epoxies, 330 retains some elasticity, not so's you can wiggle or visibly move it, but it allows the adhesive to bond materials with widely differing thermal coefficients of expansion (steel directly to composite, etc). Works on numerous different materials.

Couple of concerns, if you need to remove it, it has to be heated, which would be a problem if necessary to remove an item without grinding or cutting.. It's not cheap and it has a one year shelf life (which they are not exaggerating). It must quit working on day 366! Buy only what you need.
