Not sure if this is the right section.
I've been working on a couple of machetes lately... I had one just about finished and was testing. Very pleased with it, rolled leaf spring, full quench, tempered at 400. Got razor sharp and great flex in it. Decapitates yucca's with single handed, single strikes
I've epoxied/pinned the handles on using Devcon 2 Ton (somewhat old, like 2 years). Plenty of cure and set time. Was working out pretty well, until my last round of testing with my offhand, must have not hit dead on... I noticed as I was flexing the blade that the epoxy was separating at the top of the first pin, closest to the blade. So I popped out the pins, which seemed easier than it should have been considering that I epoxied them in as well, and started to pry the scales away. Needless to say, it seperated quite easily on both sides. The epoxy appears to have adhered to the wood (white oak), very well, but not at all to the steel seemingly. I did acetone/alcohol clean the steel before epoxy, and the surface is not really smooth, as I left the forged finish on the piece and soaked in vinegar. I did thoroughly clean after the vinegar.
Was my epoxy simply too old ? Or is it the wrong epoxy for such a flexible blade without a real guard on it ? I do have some much newer G-Flex which I am going to try next. Should I bother scraping/sanding the old epoxy off the scales, or would it be beneficial to leave it on with the new epoxy ? Just want to do it better next time. This is a personal blade not meant for anyone, but I would like to do extensive testing on my process before I try and sell a few. Can't have blades break, or handles flying off you know
What do ya'll think ?
