Default RE: Ipe, boo, trilam build along.

I have decided to put a power lam on this bow. Since it is a trilam with a belly lam up the riser, there really is no need for the power lam. Im putting it on for ascetics and nothing more. Usually a power lam is used to stiffen the handle area, on static grip bows to keep from popping off a handle. It is placed between the backing and the belly in the middle of the bow. Im going to cut this lam from the osage I just cleaned up. My design is going to call for 6" grip with two " fades. Your power lam needs to be at least 1" longer than your gip and fades combined. This way the lam will go 1/2 inch passed your fades. Here is the power lam. I simply riped a 1/8" strip from the Osage I just cleaned. Since my riser is going to be 10" total, I cut this lam 11 1/2". I put the extra 1/2" on so when I grind it down, it will retain at least 11".


I marked the center of the lam and went to the belt sander to tapper it to a paper thin on each end. Power lams can drive you nuts because they have to tapper down real thin so that the backing will not have a gap between it ,the lam, and core.



Power lam done. I took a pic of the profile so you could see how it tappers from about 1/8" down to paper thin edges, but the pic did not come out.
