Well I started with a pre tapered core and glued on a backing no handle riser. It was going to be a simpe longbow with reflex. I put the glue on and got it all wrapped in plastic and then rubber straps. I had blue tape on both back and belly to prevent extra glu from getting on the bow. Normally I only put tape on the back. Well Anyway I put it in the form and came back in the morning. took it out and realized I lost track of which side was up with the blue tape on both sides and did about the dumbest thing I could have done. >:( I put it in the form backwards and I had glued in deflex instead of reflex ::) ;D Ok so that sucked but I wanted to fix it so I tempered some bamboo and glued it on the belly and forced it back into a reflex shape. When I took it out of the form it was dead straight with maybe just a touch of deflex :( not exactly what I wanted but oh well I cut out the taper, strung it up, and pulled it to 27" It didnt look too bad. A few stiff spots but not bad right off the bat. I unstrung it too work the sides a bit and got disappointed again :( All the deflex was back ??? Must have not let the glue cure good enough or something. Oh well. This one is now in the pile with a few others that didnt quite work out. Cool trying the bamboo belly though. I didnt bother to correct the tiller. Here it is pulling 70# @ 27"

For a bad one it looked like a goodie!!!
-
Here it is after rest. Not horrible but Im not likely to use this bow :) about 2 1/4" deflexed and it kicks like a mule ;D Im sure that could be fixed with some lightening of the tips but Im just gonna take this one as another lesson learned and move on. :)

Come on Jesse lets see more pics like braced, unbraced and the one where ya smacked yerself upside the head when ya realized what ya had done >:D
-
The ipe core was from David and I didnt do one bit of tillering on it.

:D :D :D It took me a second once I realized but then I just looked at it and laughed :D

:D :D I'm not laughing at ya Jesse... I'm laughing with ya. That had to suck!

Jesse, If you use TB3 it really needs a few days for the glue to dry out,cure since it puts a lot of moisture into the wood, and its easy for it to take a bad set when pushed before its ready..
Also if you used TB3 you can heat it up and slip off the backing if you with with a knife and re-glue it..
If you used epoxy/Urac then just make the tips smaller, and use heavier arrows..But I don't think it should beat your shoulder all that much if it gets tuned right..

Jesse, While making a selfbow recurve once I bent each limb tip in different directions. ::) We all have those days when we have other things on our minds and probably shouldn't be working on bows. ;) What glue did you use?

Jesse
I'm thinking of a couple of funny Polish bow making jokes.
(mods. don't worry I'm Polish ;D)

:D :D thats awesome Pat I love it :D yeah this bow fought me in more ways than one.
I used smooth on epoxy. "messy stuff"
Rich The bamboo on the belly is a piece I got from you quite a while ago. Im not really interested in saving the bow at this point. I can make another easy enough that I like better. :) Im not sure I would intentionally make a bow with an ipe core and a boo belly. I think the ipe might be better suited for the belly. I would however really like to try a boo back and belly with a lighter core like maple or cherry. Sounds like a good idea to me but I dont know.

Let em rip. I got it coming :D

well since you are scrapping it anyways... why not try to make it a bamboo backed bow instead of a bow with a bamboo belly? String it backwards and see if it holds together... Might as well... :) -josh

Josh its bamboo back and belly I do believe ;)

Exactly what I was thinking.......string that sucker the other direction and you got reflex ! :o
-
Sometimes you just gotta laugh. I remember Milo posted pics of a nice static recurve once with the tips bent in opposite directions like Pat said. I'd try stringing it backward, too. Or kerf the tips and recurve them.

I'm with Hillbilly..

Im thinking stringing it the other way may not be best but I really have nothing to loose. The belly is pretty cooked and Im afraid it might be short lived with a heavily heat tempered backing. Believe me I thought about it :) I didnt however think about kerfing the tips and reflexing. That sounds like another good thing to get some experience in even if it doesnt work out. I might just try that. Thanks for the suggestions guys. If I dont kerf it I will just string it the other way and see if it can take it.
-
Jesse, I think that is worth trying to kerf and reflex the outer limbs especially if you can get a clean cut along the glue line..
-
Dont know if this was a good idea or a bad one. I decided to cut it in half down the middle and put it back together adding reflex. I cut it in half but had to sand a whole bunch to get it flat again. "might be a light weight now im not sure yet" you can see that the piece curving up was the original screw up side with a bunch of deflex. the one curving down was the fix. I can see now why it didnt work. The original deflex had a lot more power stored than the reflex I added. By cutting in half you can really tell. Well Im not going to be able to do much tillering on this when it comes out of the hot box because its bamboo on both sides. I just eyeballed the thickness taper and tried to get them close. I'll be surprised if the tiller is even close :D.
Also I hope it doesnt come out twisted. It was already tapered straight from 1" to 3/8" tips so no room for error to adjust knocks. I strung it backwards instead of using a form. Hopefully that keeps the string down the center. Stay tuned Im gonna take it out tomorrow.
See how many times one bow can get messed up ;D

Well I was right that it is now a light weight/ youth bow ;D Tiller came out lousy but I can work on it a bit though the limbs are very thin already so I doubt I can get it the way I want. Hope I can get it straightened out enough to give it to a kid at least. One good thing is that it didnt take set. Here it is pulling a bit over 30# @ 25".

...cut an inch off both limb tips and it will gain 10lbs... then it will be around 49# @ 28" if you add 3 lbs per inch of draw weight that is... ;) -josh
ps the tiller doesn't look THAT bad to me... :)
-
Thanks Josh I might just cut it another inch or so. Im not sure if it will take it though. its 60"ntn right now with almost 13" non bending in the handle due to a long powerlam I put in when it was going to be a heavy longbow. That would make some mighty short limbs but it seems good so far and I have no attachment to this stick so if it breaks it wont bug me any. This is the first bamboo belly I have tried so I learned a lot from it so far and pushing it till the break/ heavy set point might give me some more knowledge. I just hope it blows on the tree if its gonna blow ;D. My guess is that it will take a bunch of set if I cut it shorter and take it out to 28"
