Hi Guys.
I want to start my next FG lam bow and I want to make a bit fancier. So I thought of making spliced limbs put of maple and walnut. Not something complicated, just a simple 45 degree splice. I do have a few questions:
1) When do I splice the wood, before or after ripping?
2) When I gring the lams to thickness, is there a danger to the splice?
3) what glue do I need to use?
4) Assuming I use 2 lams per limb (1 paralll and 1 tapered), do I just glue`m up the same as usual, or do I need some kind of middle lam in between?
I anyone can point me to some sorces on the subject, that`ll be great.
Thanks
1) before
2) only if your glue joint is bad
3)I use smooth on
4)I use them as veneers with core lams
I do just like PV and have had no problems at all. It is a great way to make use of fancy wood that is to short for a full length lam. Mine are usually about 3/4" thick then I rip them and grind into veneers.
Thanks.
A couple of more questions:
1) Can I use the spliced lams as the main stack (not as veneers) and just use a strip of stabil-core carbon lam between the lams? As said, I use 2 wood lams +2 glass lams per limb.
2) If so, how should I consider it in the total lam thickness? As wood? Does it add more/less draw weight then wood?
To be safe I would think you need glass over the splice and at least a solid core lam between the two. I know I tried to use all curly maple as core nothing else between glass. And because of the cross grain the bow blew on the scale.
No you should cut them as veneers and reduce the rest of the stack. I generally make my veneers 0.025 - 0.030
