Yeah, it does look thin, like 1/4" or maybe a bit less? I found that copper really transfers heat quickly and popped my first liner I did with it when I was shaping the front, had to re glue it. I found JB Quik Weld or the regular JB Weld works pretty well and doesn't pop as easily when it gets heated up.

I never got this hot at all. I used a milling machine to make a mechanical joint between the copper ferrule and buckeye burl body. The joint was tight enough that I was able to shape the handle to completion without gluing it together. Once it was all shaped, I epoxied it together and all I had to do was hand sand it which built no heat.

That is awesome to have the machinery to do that!!! I went nuts when I tried my first copper liner, popped off twice I think when I was shaping it. First time was Devcon 2 ton, second time was JB Quik-Weld, but it hadn't fully set up yet. I did the Quik Weld and let it set fully and it finally stayed on the handle material. I think the copper ferrule looks really nice and sets off the wood on your knife!!

Yeah, the mill is a really nice thing to have. Probably won't use it a ton, but when you do it's really handy.

BTW, I really like G Flex epoxy from West for handle work. Best I've tried so far.

I've been stuck on the JB Quik Weld lately. I can shape out the handle in 30 min to an hour after I epoxy it. If I have a few knives to do, I do one ( cut, drill, shape the front of the handle and epoxy and clamp it) and by the time I am done with the second handle, I can go back and shape out the first one. It's a pain buying it in the little tubes though. I buy 3 or 4 tubes every month, if not more from the local hardware store.

I've been using the MAS Epoxies for laminating my own handle materials, but I haven't found an epoxy from them for attaching the handles to the tang. I will have to give the G flex a try and just let it sit overnight. I would probably glue up several knives, let sit over night and then crank them out the next day. It takes a bit longer. I work 3rd shift at my normal job, so I usually only have a few hours each day to work on blades, unless I have the night off and no fishing rods to build.

I've always avoided JB Weld in any form of handle construction except the odd time when I use it for gluing pins/bolts in place. There was a "Glue Wars" some time ago when a myriad of epoxies and glues and what not were all tested extensively and JB Weld came in consistently in the bottom when adhering wood to metal.

I've been using it for years with no problems, even used it back late 90's-early 2000's when I was doing the whole knifemaking thing from barstock. Go figure! From one of the reviews I had seen from various knifemakers, the JB weld did better than many other ones. Lots of guys use Arca-glass type epoxies, too.

Any time you are using copper you have to be careful not to overheat. Many epoxies, even G-Flex, which I swear by, will break down when overheated. Any time I get asked to use copper, I know am in for a long shaping process because you have to take it so slow.

That Adam was able to shape it off the handle is pretty cool, especially considering how soft copper is. I really just keep coming back to this thread to stare at that piece.

Yeah, taz, it's weird. In the end, we all have to use what works best for us. :)

kalaeb, thanks! :)

Adam,

Do you also use the G Flex for wa handles?

Thanks.
