Hey folks,
Just lookin' for some pointers on how to proceed with this bow. In the video it is at a low brace height of about 4".
Boo/Ipe/Hickory 76" long. Hoping to end up anywhere over #90@32"
Thanks for checking it out!

I can't see a thing wrong with that, looks like it's coming around perfectly. I've got a similar bow ready to be tillered, just have a few other projects to finish up first. Looking forward to seeing this one completed!
-
Thanks for the feedback Cameroo! Much appreciated. Good luck on yours! I have many distracting projects as well, haha.

Well shoot. A bit of the bamboo backing has cracked and lifted just below the center of the bow.
How should I handle this guys? I really would hate to scrap this piece of work because of this. Is it as simple as supergluing back down and applying pressure?

Glue! It's in the middle, and it's longitudinal. You don't need to worry, just flood it in superglue and press it down, and carry on as if it never happened!
-
Sweet! That's what I was hoping to hear! Thanks WillS!
-
Hang on. I've just looked again. It's actually popped a splinter hasn't it, right near the centre line. If it was just a single longitudinal crack you'd be alright, but I'd wait for somebody more experienced using boo as backing to offer advice! Sorry!
-
Alright, I'll hang off on the glue. That splinter runs about three inches long :(
-
My experience would be that the backing is a lost cause, for a warbow weight bow anyway. It will most likely pop back up no matter how you patch or glue it. That has been my experience at least. I would cut the backing off, just above the ipe core, and sand back down to the ipe core and glue another backing on it. That always sucks. I recommend very sparingly removing the rind next time, and don't go below a 1/32" of an inch for the backing.
-
i thought i would help even though ive never made a warbow. i had stuff pop splinters and what i do is fill it with superglue then i wrap sinew around it and it is soaked in glue. idk if it will work for that weight tho.
-
You can only try it and see.
I was going to suggest the out 1/3 of the limbs could bend a tad more. That would also help take some weight off that grip section.
Bear in mind laminates are not my thang... so I reserve the right to be wrong!

Thanks for all the replies guys. I think I'll go with Toomanyknots on this one. This bow has been sitting as a stave for over 2 years now :o maybe the boo just dried out a bit too much, idk.
I think a hickory backing would suit this bow well. A few questions about that, should the hickory be brought to a single growth ring? That seems like it would be ideal. Is it possible to use a hick backing that is not down to a single ring? If so what should the orientation of the grain be in relation to the bow?
-
And that's why I don't use bamboo anymore...

Here's a 60# hickory backed yew. This is how I orient the grain.

Maybe. In my opinion, (of course it is too late now though), but in the video you can tell it is working a bit too much in the middle, not enough everywhere else:

I would try to leave the middle stiffer (for about 6" - 8" in the center), and work everything else, than later on in tillering you can lightly scrap the middle to bring it around, that is one way. When I have removed the backing and re-glued another one, I cut it off on the bandsaw right above the core, and then use the belt sander to sand the rest down to the core I want, that way you make sure you don't cut too deep and ruin it.
