I just cooked my first two take down longbow limbs. One had about 3/16" slippage to one side. I think I can salvage it.
My question is this, does anyone have a special set up on their forms to keep this from happening?
I used the small finish nail throught the but end to keep the lams from slipping toward the end of the form and it worked good.
I'm thinking of cutting some thin strips of wood and glue and nail them down the length of the form to act as a wall for the edges of the laminations to sit against. I think this would work. Plenty of paste wax would be in order to prevent adhesion.
See if this works, its from Ric Anderson.

Wrap your laminated lay-up with masking tape in a few spots before you clamp it to the form. This should hold everything together while you secure it with clamps. Pat
I use large fender washers with a big center hole held on with a smaller washer. This gives you alot of adjustability up and down and a nice rounded edge. Held on with a sheetrock screw that I predrilled a small hole for. Three per side. Cheap and easy.
This is what I do. Used scap pieces of steel and alum.

Very good ideas guys thanks!
I do have a lot of "squeeze out" when I air the hose up. I'm always afraid of a de-lam from chincey glue application. This is one problem I have while checking the "lay of the lam" pun intended...LOL. Too much glue hinders seeing and feeling the edges of the laminations. Do you guys apply glue to both surfaces of a lamination or just stack them and slap the glue on only the tops? I do both sides.
Yes allways both sides. I to probably over glue but I know I have plenty. Just dont apply all the air pressure in one big shot. Go a little at a time to let the excess squeeze out.
I bet that is what did it. I had to let air out and re-shoot it to get it to the recommended 60lbs. I bet that is when the slippage occured.
First make sure your lams are the same width as your form. Then cut some wedges that will fit between the form and the straps that hold the top and bottom of the form together. You want them to be just wide enough to cover the lams and some of the bottom form but not on the air hose. Tap them in on both sides of the forms. I cut some out of the scraps that were left over from the riser sections of a one piece bow. Tap them in before you pump up the air hose.
