My horn bow build-a-long

<< < (11/69) > >>

DC:
 I've taken the test limbs off the form and there was a fair bit of springback. I glued a piece on the sal end of the eye and rounded off the eye a bit. You can see the kasan eye bend is not so tight. Hope that's enough. I may make the tip bend a little sharper. I set it at 150° like The Book say but I may go to 140° to account for springback. It's also a lot easier to pull bend out than put more in. I didn't see any mention of springback in The Book. Maybe the longer soaking and drying would help. I should have waited but at least I'm working on something. I'm squaring up one of the test limbs pretending this is the real thing. I'll splice a scrap handle on it and see what happens.

DC:
I managed to get registered to the ATARN forum but there's only one or two people on there. Maybe more will show up.

DC:
My test limb and practice grip to sal "V"joint. I've never used hide glue for a joint, should the joint be a loose close fit or does it matter if you have to tap it home?

bownarra:
The main criteria for the fit of the joint is that there is no light showing through once they are fitted together. It doesn't matter if the joint needs to be tapped home better that than too loose. The hide glue is perfect for gluing splices. Sizing parts well (with heat), apply thicker glue and push together. Let the glue gel properly. Then clamp lightly. I've done them with no clamps when the splices are perfect with no problems. Make sure and apply a fillet of extra glue once clamped.

gorazd:


-close fit as possible
-make the joint area rough with saw blade (longitudial moves with saw blade for metal - small teeth)
-the joint area should be sized well with thin (hot) hide glue - at least 5 times. Let the thin glue penetrate wood properly and dry after each layer .... 10-15 minutes (gently heat with heat gun)
-Then make the glue thicker and put one thick layer of glue
-put the clamps on and tight well
