Laminated stock glue

I am wanting to make my own laminated stocks and was wondering what type of glue or epoxy is used?

Laminated stocks are not only glued, they are subjected to intense pressure when they are made to force the dye through the wood and to make the layers form a permanent bond with the glue.  I'm not sure that you could make one yourself that would be as strong as one from a stockmaker.

Laminates are made with layers of wood with an epoxy type glue between each layer. They are then put into a press and subjected to vacuum. This removes much of the air in the wood cells and when the vacuum is released external air pressure forces the glue(not yet set) into the air voids. Thus the slabs aren't just glued together they are impregnated with the glue as well. Any high strength epoxy would hold the wood layers together but it would be difficult to duplicate the vacuum trick. But do you really need to? A perfectly usable stock blank could easily be formed by simply compressing the glued up blank to compression(clamps) before the glue is set. Wax paper would be a good choice to keep the glue in place(relatively speaking anyway) and to act as a release agent for the home made clamping system. In fact there are manufacturers who use thicker slabs with stabiel wood cores and fancy wood exteriors. The slabs thickness varies from 1/4 to 1 inch. They can make some interesting patterns when they are carved into stocks..

I used to make recurve bows for a hobby, and used most of my stuff from these guys.  http://www.binghamprojects.com/kits.htm  look about 1/4 of the way down the page at the epoxies.  you'll need resin and hardner.  You can also buy laminated blanks from these guys and they may be long enough for a stock.

To make this stuff work it has to cure under pressure (C clamps work fine, just use plenty and spread the load out evenly)  and heat.  I made (according to their instructions) a wooden box (any good enclosure will work) heated by 3, 200W light bulbs.  Yes they do make it hot enough.  The curing temp I used was 180 degrees for 6 hours.  Trust me you will NEVER seperate those laminations after this treatment.

You can buy the lams from these guys already stained and lay them up the way you want.  If you have questions call them, they are very helpful, and are used to working with newbies.

THe outside lams need to be glued on the inside part, all others lams, on both sides.  The key is a good even coat, with no gaps, and about 60 lbs pressure.  Try c clamping the scale to test.
God, Family, and guns, in that order!

Thanks to everyone who replied.  All the information was very helpful.  This might very well be the greatest internet site available to shooters.
