HI there,
Long time reader of the boards, bur firt time poster. I have some garapa that I got from the local hardwood lumber place and I have it backed with hickory. The garapa is VERY hard and dense and prone to splitting and chipping when working with sharp tools (i.e. spoke shave, plane, etc) but can be worked with files and rasps much easier. It takes a very nice sanding and polish as well. Becareful of the dust however, it is irritating! I haven't gotten the bow made (still in the rough outline form) but it should be a 70" bow where I am hoping to have at about 50# or so. Hope this helps
