Well I got the riser and limbs done now to put in the hardware. Any tips would be greatly appreciated. Thanks for everyone's help.
-
Only advise I can give is to cover all those pretty finished surfaces with blue tape. Hate to see that beautiful finish marred.
-
Would be much easier for yourself if you made the drilling and installment of hardware before shaping the limbs and riser. I have never seen it done your way.
Good luck.

What Bue said, in this case, I would bolt the limbs to the riser with no pin, mark center on riser and where the nocks will be, run a string on it to get all lined up as good as you possibly can, then drill the pin holes right thru the limbs and into riser . This way you will be as aligned as possible cause you got no wiggle room shaping limbs first.
Then put an overlay from limb butt up past pin hole on outside of limb.
That would be my thought, maybe somebody will have a better way!
Beautiful bow BTW!!
-
Yeah you got the cart before the horse on this one. Kenny is about right at this point. What is the riser wood ?
-
Thanks guys. Thats why I asked for tips. I realize my mistake but it's too late now. Maybe I can save them.
-
Limb alignment can be a pita, but stay right with her. I learn something on every bow , some I have learned before and still make mistakes....
-
Could I put the bolts in first on both limbs get them aligned then drill the pins?
-
Yes...

Bolt the limbs on without pins, run a light string from tip to tip and check center at riser. Then drill thru limbs into riser to get limb alignment as close as you can.

I'm sorry Kenny I miss read your first post. Thanks again.
-
No worries!! Stay with her!
-
Did you do any tillering of the limbs before finishing them? Have you determined which is the upper and which is the lower limb? You might want to determine which is the stiffer limb before bolting them on otherwise you may not be able to reverse their position after the hardware is installed.
-
I fabbed up a set of limb pockets out a pair of Aluminium L channels in a similar situation. Painted black they don't stand out, but it was a dark riser/limbs. If I did again I'd probably make up a mold and do it in carbon/glass instead.
It did give a bit of wriggle room to line everything up nicely with a string line from nock - nock over the riser. If you make up a jig for drilling the limb bolt, it should give you the option of swapping them over for tillering or alignment if needed.

No tillering done just cut the tips. Got in a hurry to see how they turned out. I have some leftover black glass and thin strips of wood and some clear glass. You guys think that would be too much over the butt ends?
-
Well at least it looks like a bow
-
It looks like i got the string running center. What you guys think.
-
last shot looks like alignment is good. Re drilling the bolt holes etc., I do it the way Kenny said as a matter of choice.
-
Hey guys I finally got the limbs on and the string is tracking down the middle but I have a little twist in the limbs. My question is do I take some off the high side or low side? Thanks.
-
It will pull to the weak side. first try deepening the the weak side string groove some to see if that helps. then if it is still off sand the strong side. be sure your string is not binding in that groove before anything. go ahead and shoot it a few times and see where the string settles in. I even move the string on end in question over some the other way and shoot it to see if it comes back and shows the same twist.

Thanks for the help guys but it looks like I have to start over. Was stringing it today and pow there goes one of the limbs. Looks like the lams gave out.
-
That stinks Bobby.
Looks like you had an adhesion problem since there are no wood fibers on the outer half of the fiberglass.
-
Twist and shout!
That sucks, at least you only need to make one new limb.
-
Was that the limb that showed the twist ??
-
That stinks Bobby.
Looks like you had an adhesion problem since there are no wood fibers on the outer half of the fiberglass.
did you apply glue to every surface to be glued together? By that I mean in the core all sides get glue and the one side of the glass. (Ask skeeter about which side...)
Just askin...
-
Yes glued all sides. And I glued the sanded side of glass. The wood had some sawdust looking pieces where it shattered. Thats what makes me think it was the wood that gave. I took a piece that was cut from the same board that was about 12" and bent it and it snapped with out to much of a bend. Thats the way it goes sometime.
-
I'm thinking what Stic is. Looks like it could've been draw back with a limb twist. Sucks no matter what caused it.
-
What I am thinking if that is the limb that had the twist starting to delam may have been the reason of twist. What is the wood there?
-
The wood was cherry. I had removed the limb twist the night before. And was about to take it out to shoot a few times. I didn't see any problem spots but I guess there was somewhere.
-
Cherry may not be your beat choice for core wood. As veneer .030 ok.
