Title: Can it be saved
Post by: Kopper1013 on November 06, 2017, 04:36:00 PM
So I'm trying to build a longbow for my father and while I was sanding the limb profile today the belt broke on my spindle sander grabbed the limb and lifted a huge fiberglass splinter about 1/8" wide at its widest but 7" long and most the thickness of the .05 fiberglass belly. What can I do? Is it possible to remove the glass and put on a new piece? Or is she toast?

Yes a pic would be nice.  If not,  where is the splinter in the limb?  Along the edge?  You may be able to trap the belly enough to remove the splinter?  You will lose some weight, but still make a bow.

Kopper, check out imgur.  You can upload your pics there for free and post them here (I'd recommend doing from a desktop, though, as it's a little frustrating trying to upload from a smartphone).

How stable is your limb when strung? Dont string it right now if you not sure. You may be able to trap that. I normally do not trap the last 6" of the tip as it weakens them or rather it causes them to open a little too soon.

 I would mark 1/8" on either side of the back of both limbs and trap to the belly just enough to remove the splinter. At this point you cant glue anything too it but if you find the tips have become too weak you can make a tip wedge and glue it on the belly and make the limb nocks thin and longer as well to stiffen the area back up.

I would probably try and trap that splinter out also.

But...another option might be to glue the splinter down with CA and then add a glass underlay on the belly to just cover the splinter?  Feather the underlay into the limb.  By the time you are finished sanding and rounding edges there wouldn't be much of the splinter left.

Try something and see how it goes.

My thoughts exactly. Nothing to lose gluing it down and adding underlay. If you end up sanding the splinter away in the tiller/shaping then all the better. If not hen at least it's secured down some.

Use EA40 not superglue. Wrap it with innertube for the clamping pressure.

Thanks guys, how do you wrap it with the inner tube? (What's the technique?)
