I've used all sorts of methods to clamp due to the odd shapes you can run into. If the crack is deep you may need to spread it as much as possible to get your glue, epoxy, whatever you use, deep down inside. Sometimes it's easier if the stock is broken and you can repair it using dowels and coat the surfaces evenly. It takes 30 minutes to begin to harden so you have much more time to work with it.īut it depends a lot on the location and type of crack. I've had good luck with Devcon 2 ton 30 minute Epoxy. If you must use an epoxy-type resin, thin it 50/50 with whatever solvent it calls for, and under-catalyze it by about 10% so it will have time to penetrate before it cures.Ĭyano glues are hopeless for stock repair. Being rather thick consistency, it does not penetrate well, so it sets up a rather thin bond-line that will break away from the wood if stressed. Gorilla Glue expands in the crack, so it has to be VERY tightly clamped or the stock may take on an unexpected dog-leg.įibreglass resin can be made to work, but it is no magic cure-all. Gorilla Glue would work, but the surface residues (if any) are very difficult to sand off. It does need time to get fully cured if it's a deep crack though, so don't go out in the rain for a couple of weeks. Sometimes a 20' length of bungee makes a perfect clamp. Once the crack is clean, I personally use Tite-Bond II wood glue, and clamp as tightly as I can for 48 hours. A can of Brakleen would work after a fashion. (Both are hazardous, use only with a LOT of ventilation.) Paint thinners and alcohol won't do much. Lazy man's way is aggressive solvents, such as xylene or MEK. ![]() If the stock was linseed-oil finished, you will have to re-oil. Boiling the wood in a vat was the old way, the new way is to run it through a dishwasher, (yup! done it several times!), using straight TSP, not the crappy dishwasher soaps that the EPA mandated upon us. Best method is very hot water and trisodium phosphate, (TSP). I restore old guns, so I have more than a passing acquaintance with this problem.įirst and foremost, get ALL the oil out of that crack.
