Gorilla Glue Test on M-39 Split, Results

[Cosmoline]

I recently posted in the Gorilla Glue thread about an M-39 I bought with a cracked stock.

Today I partially assembled the M-39 and took it to the range. I put it together with no accessories, just the basic repaired and partially cleaned stock and barreled receiver. I wanted to make sure the stock didn't get any extra protection from recoil. I then ran about 200 rounds of Albanian surplus through the poor thing in three batches of rapid fire, stinking up the range and making the barrel hot enough to smoke the oil out of the end of the stock. That's about as much as I'm willing to push a 109 year old receiver in one sitting.

Results--the split didn't budge and the glue, amazingly enough, held together. I must admit I'm a little surprised after all the reports indicating it would pop back open when it got hot and battered. But we shall see. I'm going to have to refinish the stock due to that crack and others.

Pics of the repair in two shakes.

Sadly, there was no way to repair that serious a crack while maintaining the original finish (or what was left of it)

I'm also a R/C modeler and have pretty much stopped using epoxy since discovering polyurethane glues... seems just as strong at a fraction of the weight (a major comcern for R/C). BTW, Elmers Ultimate is the same stuff at about 2/3 the cost of Gorilla glue.

Elmers Ultimate ?

Thanks, I'll look for it. JT

I am still a fan of epoxies for gunstock repair.
I use Accra-Glass Gel for big cracks and regular Accra-Glass, less the fibreglass floc, for repairing smaller cracks.
I have also had to use brass pins capped with wooden plugs to repair some major breaks.
I have never yet had one seperate after repair.

I may end up resorting to a brass pin, but for now it's holding OK. Here it is after some new BLO
