Epoxy and scorched wood adhesion?

I have a friend's pinned, hidden tang filipino practice sword that had the handle crack. I do have a replacement solid wood handle from the maker, but both the original and replacement handles seem to have been "bored-out" with something hot rather than drilled out.

I was going to notch the tang a little bit (for adhesion) and fill the handle with Devcon, and probably pin the handle, too. But will the epoxy even adhere to burnt wood? Should I do something else to prep the handle first?

Thanks! :)
 
Not exactly the most 'ideal' surface to adhere to (burnt wood), but as long as there is no loose debris in the hole I suppose it would be OK. Ideally the surface would be clean, rough surfaced wood.
Maybe it would be better to use the 'new' handle as a pattern to pull the dimensions from, and make a new handle yourself.
 
Thanks!

I'm actually also attempting to make my own handle out of Micarta (thank you Pinoy Knife!), but having a 10-month old son means I get into my garage to work on these things less than I'd like ... and I'm untalented/unskilled as hell. ;)

I might try something like a butter knife wrapped in sandpaper to get the inside roughed and cleaned a bit.
 
If you scrape out the insides some it will greatly increase the adheasion. use a round file/rasp. I made a scraper from an old file. it has a 90 degree bend 1/4 inch from the end. :cool:
 
Scrape out the burnt wood as much as possible. Put some gouges in the wood to provide some mechanical locking action. Same with the knife hande, notches or small pins. Avoid using Devcon when ever possible. Cheapest way to glue would be Golfsmith golfshafting epoxy. Great stuff from golfsmith.com
 
The neatest tool I've seen for this was from Chuck (teaches at JC Campbell). He had taken an old saw blade, from a reciprocating saw I think, ground off all the teeth except for about 3 on the end. The whole thing was a 5" blade with a handle on the end. When fitting 'burn out' handles he used the teeth as a kind of scraper to pull out most of the burned wood. Only took a couple of minutes to do what it had been taking me a half hour or more using chisels and files.
Thanks Chuck,

Unfortunately I will be using Devcon for a while, because I bought two syringe packs of the stuff right before the Great Glue Debate occured here. ;)

Thanks, everyone, for the tips! I really appreciate the info.
