MrMike, you are gifted!
I'm new to the forum so I read this for the first time. Are you still looking for Devcon epoxies? I'd recommend the industrial versions as they have a lot of different formulations plus they tell you about their qualities. A lot of epoxies will withstand up to 300-400F before they "let go" though they may start to soften earlier. One thing to consider is their ability to with stand shock and not "sugar". Cheap consumer epoxies often are the bottom of the barrel in terms of quality - they may look and smell like epoxy but the similarities end there. When you say "epoxy" it is a very general vague term and getting the right one for the mission at hand takes some reading. If the epoxy is too cheap other than to provide some vague PSI statistic, I'd recommend avoiding it.
I've used Brownell's Acraglass for a number of projects involving firearms and it seems very durable. I know they did a lot of homework before they settled on whatever it is they use and you pay for it.
In terms of DevCon, here's the manufacturer's site: http://www.devcon.com/products/products.cfm?brand=Devcon&cat=Epoxies and I am just listing this as an FYI.
Most of my experience is with their metal repair products and I use their plastic steel and aluminum putties and liquid a fair amount. A lot of guys will use one of these to bed rifles because they withstand shock very well.

In terms of surface prep, rough and clean are better. A liquid epoxy will soak into the wood pores pretty well from what I have seen. I am assuming the tang is rough and/or has holes. If you hit it with 60 grit sandpaper that will help with bonding. In terms of clean, use acetone or brake cleaner - you want to make sure all grease and oils are gone including from your hand.
Now, you can buy this stuff relatively inexpensively from industrial supply houses like Enco, MSC, etc.
For example, Enco has a 1 pound container, which is actually quite a bit, for $32.98 (make sure you get the liquid).

Hope this helps give you some ideas. There are a lot of epoxies on the market.
Also, let me give you a broad generalization - the longer the epoxy takes to initially set (what they call working time or pot life) and then cure fully, not only do you have more working time but the stronger it is. Sure 90sec, 5 min or 10 min epoxies can be nifty when in a rush fixing something simple but for really strong stuff, look at 12-24 hours and look at both the pot/working life as well as the cure time. The pot/working life is important because you need enough time to apply it and position everything.
By the way, take the time in advance to build something to hold things in place firmly while everything cures - don't leave work holding to chance - especially looking at all the time you've invested in your handle. You want it held together with all the angles right vs finding out it is crooked the next morning when it is too late. Let me stress this - once the epoxy cures, there isn't a very pretty way to get it off and then get as good of a bond as you would have had if it had been done right the first time so you want to make really, really, really sure you get everything right the first time including very thorough mixing, surface preparation, work holding, etc.
Hope this helps some.
