My horn bow build-a-long

<< < (55/69) > >>

DC:
I'm trying this. The light bulbs are heating the belly to just under 50°c. I fiddled with the distance until it was right. Now I can just let it soak. I'm checking the temp every 5 min. It's been going a half hour or so. It's just hanging on the pegboard. Maybe kinda Rube Goldberg but I've tried all the other ways I can find.

I let it heat for 1 1/2 hours. The back was at 45+°c for most of that. See what tomorrow brings.

DC:
Bownarra, I remember you saying way back that something about the shape of this bow was going to cause me trouble down the line. This is a picture from right after I glued the horn on. Is it possible that the glued in reflex in the sal area is whats stopping it from straightening out as much as I want. I've done everything you've suggested and more and it doesn't want to open.

DC:
I decided to bend it and live with the consequences. It doesn't look too bad to me but what do I know about these things. Should I move the peg holes out a little further? I really think I've just got one more hole to go to get to brace height. I'll paint the board black so I can see things a bit better. :D

bownarra:
Yes what you've done would have been my next suggestion! Bend it further to see what is going on. Yes I think you are right about the sal reflex/core shape.
Now that it is bent on the pegboard the kasan eyes have opened, can you see that area bending when you bend the bow on the board? The sals look to be bending a little too much close to the handle but with the reflex in the sals having to straighten out first it may be misleading. If you leave it sat like this for a while the temporary set you will see when you take it off the board will tell you where it is strained or not. Having the bend a little closer to the grip isn't a bad thing really as it will make the bow a little more stable, easier to string and won't stack as early. You do get more set in the inner limbs but that isn't a big deal.
Pegboard holes look to be in a good place on the bows limbs. I would drill two more sets of holes. One as far down as you can drill and an intermediary one.
You want to brace it at around 7 1/2 inches initially. They can be a bit 'wild' on first brace! Have the sections of inner tube to hand....
Once you add the holes to the pegboard take some more pics. I think the next set of holes will help to reveal how to proceed.

I'm following closely,  and every post has me waiting with baited breath!
