IME, the "standard" Araldite (not the quick set version) is one of the best available, together with West Systems, which is expensive. Also IME, standard Araldite does need AT LEAST a full 24 hours to harden fully, though hot weather can, sometimes, speed that up a little.
Agree about leaving a couple of "escape holes" if gluing into a blind hole. But make sure you remove all squeeze out before it dries. A sharpened lolly stick is a good tool for this, and a wipe with an Acetone wetted rag should remove any external smears remaining - BEFORE it's cured of course.
Be careful to get the proportions right (50/50) and make sure both the little mixing palette and "spoon" (both supplied) are absolutely clean and dust free, along with the area to be glued of course.
You'll probably mix too much at your first attempt (easy to do) but that comes with experience. Make sure the mixing spoon and pallette are clean for further use, and if you don't need the 2 tubes again for a long time, stored in the fridge (not the freezer) will happily extend shelf life of the remainder, well beyond the date shown.
