Title: Maple-backed IPE and Osage?
Post by: Knoll on January 08, 2015, 12:49:37 pm
A trip to the local hardwood store scored a 6' piece of 8/4 hard maple with straight grain edges. 

Have a 1 1/2 x 11/16 piece of IPE that's 6' long that DVS gifted me couple months ago.  And a qtr-sawn Osage board ... 1 3/4 x 1 x 6' ... picked up at MoJam last summer.  Would like to use the IPE or Osage boards to make a target bow in 35-40# and use other as 45-50# hunting bow ... both at 26" draw.

What are thoughts re using the maple as backing for these bows?  Any recommends re dimensions?

Thanks!
Michael

Maple should be fine as a backer for them. I've used maple for the heavy dense tropical woods with good success, and so have some others on this site as well.

Thanks, guys.

Seems that common backing thickness is 1/8".  Given that one of the bows will be on the light side ... 35-40# ... is it advisable for that backing's thickness to be less than 1/8"?

I always try and slightly taper my backing. I'll glue the 1/8" on then lightly sand towards the tips.

Remember you can always use a much thicker Maple backing with Ipe. You can save mass weight that way. The Ipe only needs to deliver in compression and it doesn't take much thickness to do that.
 I made one with Maple backing about 5/16 thick.

My experience with hard  maple is that the grain needs to be very straight and clear for a backing. Some broke and some were fine, all from the same board. These were all narrow longbows 1" or just under in width. I have more faith with hickory or boo, than maple but I think it is less crucial with wider flatbows.  A lot of guys have made good longbows with maple backings, so it could be that my individual board had issues.
