I have a piece of IPE that I have backed with bamboo. I am thinking of trying another layer of wood for my handle and my first attempt at tip overlays. I suspect the bamboo may not be the strongest material for the middle of a sandwhich. Dare I sand a flat spot on the bamboo and glue the next layer of wood to that? Or should I trim the bamboo back (this would seem to be asking for the Bamboo to de-lam later) and laminate the tips directly to the IPE below? I have also seen where others have filed across the wood at an angle, which would trap a wedge of the bamboo under the tip overlay, but probably wouldn't look as good as full length tip layers as you have done. I'll attach a rough graphic in case this isn't clear.

Or would I be best of in this case to save tip overlays for the next bow?

Thanks,
Keith

Knocker I split and moved your post, hope ya don't mind but I think you will get a better response here.

Cowboy I'm sorry but somehow I delleted your reply to this, still learning I guess.

keith! - ( B) and (C) will work fine;

i REALLY don't think is a good idea, it probably will open a gap between bamboo and overlay and the boo might delaminate as you reckoned.

I use method B with bamboo. Here's a pic:

Hi,
Definately do NOT use overlay as illustrated in example A!! I did, and the bow failed in spectacular fashion! The tips broke off, both, at full draw, on the first pull. I had a finished hickory backed ipe that I wanted to dress up with antler tip overlays. It was 50# @ 28'', so not overly heavy. Needless to say, it's no longer anything but firewood. Live and learn.

yes as gordon says: B is best on bamboo!

adb: didn't sound like that was a funny moment at all...

Thanks guys for the great responses - and photographs too! I am tending towards Alternative "B". I guess I don't have too much confidence in the bamboo as a gluing surface, and I'd like to get at least half of the tip glued to the IPE.

well keith, it's about getting a nice even surface to glue on; after flattening the back of the bamboo you'll naturally end up at version

. bamboo is an easier glueing surface then ipé, since ipé has a lot of oil in it!

Keith,

If bamboo can be used as a power lam, you can certainly mate a nock to it without worry. Either B or C will work.

In reference to this tip over lay thread I have an additional question. Lets say you have a self bow that you want to put tip overlays on. When do you install them, before or after you finish tiller? Danny

danny! - i've done it both ways many times, never had a problem either way!
i've seen roughed out bow blanks for sale with pieces of hardwood or horn glued on as overlays.
