Title: Learn from doing
Post by: bow101 on October 21, 2012, 08:10:01 pm
 :( Was finishing a bow today and snapped a 3rd. one. Oh well like everyone says ya learn from building, "Right"...?
I know where I'am going wrong, just got to hasty with tillering, Was pulling to 16 inches about 30 times it sort of looked good then i decided to pull it at 18 inches, that's when i heard a very faint crack.
Pulled it again to 18 and she broke....(((((But that was after re doing the brace height, i had it strung at 2 inches, then I braced it at a full 6 inches. So pulling at 18 was like pulling at 20 inches from the start..!!!))))))

I felt like Freaking, it was looking so good, laminated fir and maple. I do agree the fir is on the splintery side but with all variables in question it was not that bad.
At any rate i heard other bowyers snapping at 10-12 bows before building a succesfull bow that shot well and lasted. I will contunue to persevere.......... ;D

They break sometimes.

But, it is frustrating at times.

The maple was slightly tapered and in the center, 5 lams total stack of .390.
The bow broke in the handle section. Did not have enough taper for starters.

ok, i personally would have put the fir in the middle, and done a tri-lam with a maple belly and back,i also don't really see a need for 5 lams,but i guess it couldn't hurt

I used 5 lams to get the thickness, the lams were all cut at the same dimension. Just using what I had.
But yaaa next bow will be a Tri-Lam for sure.

Never never never make two changes at once!
If you increase the brace, then don't change the draw or poundage applied.
It doesn't hurt to even go back a bit, so if you go up to full brace then only pull to a lower poundage or length just to see what the effect has been.

I don't s'pose any bows have been ruined by going too slow.

del is right, one thing i do is when i get to full brace, i put it in a corner and leave it set for a couple a hours before i do anything, let it sweat so to speak, Bub

I like the idea of letting 'er sweat in the corner, makes sense, I'll have to try that Bub :)

fishfinder401, I have no photos, bow was cut into pieces and thrown in garbage.  :(

I beg to differ old bean! I've had some bug eaten Yew specially sent over from Oregon >:(   I was so infuriated I had to flex my little finger and say tut tut!
I've had to saw off the sapwood and I'll try bamboo backing.
Also wondered about a backing of Hazel sapling eh? eh? What does the team think of that idea.

 :) Oh hey I hear you guys, this is something I took up about 6 months ago. Just going at it real slow is all.
Have been woodworking for about 7 years, just wish I would of taken up building bows at that time. I think by now I would be turning out some actuall working bows.
It's never to late, I have been bitten by the bug I shall continue.
