Title: backing maple?
Post by: jturkey on August 19, 2011, 12:12:30 am

i was wonderign if using a thin layer of boo on maple would be a good choice. was wondering considering that maple is high in elastisity i believe i read that on here somewhere i believe it is higher than compression strength anyways so what are you guys opinion?

Maple is a good wood, somehwhat prone to chrysaling but not extreme. I think a thin boo back would work fine as long as you made the bow as wide as you would normaly make a maple bow for whatever design you are using, or at least close to as wide.

One problem with boo backings is you are limited to how wide you can get because of the concave underside. A 1/8" at the crown boo strip will only be 1 3/8" to 1 1/2" wide.   You could use a trapiziodal cross section favoring the belly and get maybe 1 5/8" to 1 3/4" wide belly.  With a bow that is a bit longer you should be OK.

I've made a 35lb @ 25 boo backed maple d-bow, about 60 inches long. It worked a treat, shoots just shy of 200yds with fairly heavy arrows. I trapped the boo somewhat though.
