good run of bad luck

[rogers]

I have been trying my hand at building laminated takedown recurves.  I was told not to try designing my own first but to build a provin design like a binghams bow.  Well to say the least I decide I could build a better one, probally pretty common though.  I used yellow pine to get the pad angles, brace height, etc where I wanted it before I started with expensive wood.

I did buy the binghams drilling jig thinkin it was fool proof.  I have built two recurves so far and the limbs on both twisted pretty bad when strung up.  

The first set of limbs I tryed straighting up by doing what binghams told me to do, which was by removing wood from the side which the tip of the limb was twisting to.  This made is worse and I the limb were not useable. I did finish the bow just the see what it would look like.

I am working on the second bow right now.  The limbs on this bow came out twisting really bad too, so I searched here on trad gang and every thing I read was the opposite of what binghams told me to do.  Yal said to remove wood from the opposite side that the twist is pointing.  This worked and straightend the twist out pretty good but not perfect.  

So I then thought that it had to be from my form not being square, so I ordered new lams and am redoing my form using the router method.

Since i have not shaped my second riser yet, just out of curiousity i put the second set of limbs on my first riser and they pulled staight enough to shoot.  Man did bow really smokes an arra!  Seems to be alot faster than my Martin Hatfield and buries the arrows about 3 inches deeper in a foam target than my hatfield, and its less poungage than the hatfield too.

So i started measuring stuff and come to find out the binghams drilling jig is off center by a 16th from the center line they drew on it.
Anyone ever had this problem with the drilling jig.

I have used mine with success, but I measured to the center of their jig and compared it to the markings on it. That 16th is enough to throw the bow tip out substantially. If I was closer I would help ya.  good luck

Thanks Mike, Iv done some more searchin on here and found some different ways of mounting them.  I think im gonna fill the alinement pin holes and with epoxy and redrill them, I just hope that the smooth-on is strong enough to hold when I drill new holes.

Glue in a piece of hardwood dowell (you can get them in 1/4")and then re-drill- you won't have any problems with the pin holding.

Thanks Trux, i would have never thought of that. I just hope I get one shootin before deer season.  I switched to trad last year from a compound and I came up empty handed but I did learn the hard way to pick a spot not just stare at the whole deer.  I really want my first trad deer to be with a bow I built with my own hands.
