I lined a kydex sheath with leather using CA glue and it's holding up amazing, no peeling whatsoever.Whoever invents a glue that actually works on kydex will be an overnight millionaire.
I’ve tried epoxy and CA, and they don’t hold well enough to use without rivets. I am trying to avoid rivets. It’s some tough stuff to glue, for sureI would probably sandblast, degrease, epoxy (gflex or blade pro ) and clamp. You could try CA glue as well on a couple scrap pieces and see if it has enough holding power for you
I will keep ya posted. I don’t have either solvent so it will be a while till I get around to it. The safety stuff is always good to know. People are always messing around with acid and solvent and other nasty stuff, often without any ppe and some of that stuff can really mess you up bad. Lot of it can end up giving you cancer. I’ve had cancer. It’s not fun. Always a good idea to be careful.MEK is another "permeator" like THF, meaning it will cross the fat/skin barrier and carry anything sitting there along with it.
THF is more hazardous by health "Safety" standards, but it's splitting hairs.
Really, with these hazardous solvents, it's important to wear the proper gloves and a chemical respirator, maybe a face shield if one is splashing like birds in a bath, but they can certainly be handled safely. Here's a chart of glove resistance. It is wise to have a couple different types of gloves in the shop, i.e., nitrile and latex if one is tolerant of it.
Sorry for the safety lecture, fellow knife makers. I was the department safety officer for several years when I worked in pharma and worry about what all that incidental exposure for 30 years is doing to me inside. I used to audit/support a production process that used thousands of liters of MEK. I don't like that stank, but THF bothers me more.
@Edwardshandmadeknives Please let us know how your experiment goes. Thanks.
Well, that wouldn’t happen in Wally World! That’s a gun free zone, they have signs by the door!I wish luck to everyone trying to find a solution for a good bond, even the manufacturer has a method, but I’m still not a believer. If it was doable I’d think you’d see a lot of people jumping on board and gluing up kydex sheaths. But being most of us use kydex for razor sharp knives and loaded handguns I’ll stick to the proven mechanical connector method. I wouldn’t want a knife or handgun to hit a concrete floor inside a Walmart from a broken glue joint on some kydex that I charged a customer for.
I like the sound of this stuff. I’ll order some up and try it.These are thermoform adhesives that bind two pieces of thermoform sheets together. E-Weld™ and M-Weld are a clear solvents that will join two thermoform plastic sheet surfaces like KYDEX™, HOLSTEX™, Boltaron™, and other PVC sheeting together in a bonded, yet flexible manner.
