Fixing screw-ups
« on: April 02, 2020, 12:54:09 pm »
I scorched the back. Not sure why or how but this is what I've got. The other limb is sorta the same. It won't sand out. I'm not asking how to avoid it, I'm asking how to fix it. I was thinking about staining the outer limb but when I tried on a test piece the scorched part stayed darker. Any clever ideas or do I just live with it?

The compromised tensile strength will be more of a potential issue.

Rawhide backing might help.
 Looks like the heat wrapped around the limb. Maybe deflected by something.

I've pulled it a bunch on the tree and as the man said as he passed the third floor,"so far so good." It does concern me though.

Rawhide backing might help.

My caul is a 2x4 and the limb is about 1" wide. I'm thinkin' that's a problem. I may slope off the edges of the caul.

I gurss fix it was the wrong term. How about hide it?

 Stain everything darker but not the spot

There could be a loss of tensile strength in that area. That's why I suggested rawhide backing. You could dye it whatever color you wanted.

If I had some rawhide :-\. Maybe just the corner of shame until I can get some rawhide.

That's what I've been trying to do. It's not easy to match colours, especially for me. The scorch isn't grey or brown. It actually looks, well my wife called it a lilac colour. A guy would say light purple :D

Sinew?  Or maybe silk.

How well would sinew work on Black Locust? I could soak the sinew off my hornbow. Hmmm.

What happened to your hornbow?

   Sinew would be fine on BL, especially if you're just using a thin insurance layer.

The hornbow exploded. I tested this bow today and it shot 181fps@10gpp. Maybe sinew. Funny thing though if I was to sinew it I would probably want to shorten it which would almost remove all the scorch :D

DC, have you ever used rosin floor covering for a backing? It's easy, quick and covers nicely. Looks a lot like a nice rawhide backing when painted or varnished.

Yeah, chamfer the edges of your form...……….Art
