Title: Questions, starting first tri-lam
Post by: Stefan on September 30, 2011, 05:21:10 am

Hi Primitive archers,

I am starting a tri-lam ELB, i am going to use a hickory backing (6mm thick), bamboo supercore (parallel strips of bamboo 6mm thick), ipe belly (16mm thick)

My questions:

1) should I plane the hickory down, to 3 or 4 mm?
2) should I add a riser piece, without planning down the hickory the thickness is 28mm? A glue up riser will probably pop off if I am going for a full compass tiller?
3) I am going to use titebond, do you rough up wood so that the glue can grap more wood?

Thank you,

Stefan

For tri-lams, I generally make my backing strips and core strips 1/4" thick. If you're using titebond glues (and I use nothing but titebond 3), then do NOT rough up the surfaces. The glue joints should be perfectly matching, smooth, and clean. If you're going to tiller full compass, then you're right, don't add a riser piece, it'll pop off. Good luck with your bow! If you need anymore help, please just holler!
