Hi everybody haven't posted here in a long time but I'm always reading and amazed at the bows you all make well I just started trying to make some and was being stubborn wanting to do it with out help but my first attempt blew up on me which was a white ash I'm now working on this one
(http://i237.photobucket.com/albums/ff161/islandcoydog/Snapbucket/A71E6C8A-1.jpg)
It's hop hornbeam and is 60" ntn 1 3/4" wide to about half the limb length then tapers to 1/2" the lower limb is an inch shorter than the top. I think I've got the tiller pretty good but would like your input here is a pic strung at full brace
(http://i237.photobucket.com/albums/ff161/islandcoydog/Snapbucket/539717B7.jpg)
The distance from limb to string on the lower limb is an 1/8" less than the top limb which I think is ok it's the same on my fiberglass backed bow. Well here is a pic of it pulled to 16"

And here it is at 18"

Well I think its looking pretty good but there is a few things messing with me. The bottom limb which is on the left has a slight reflex coming off the handle and the top limb deflexes off the handle when unstrung the other thing is when I flipped the tips I got the top limb a little sharper of a curve. I know the pics aren't real good but I hope there good enough if not I can try a better background. Well please critique and tell me what you think. Thanks Mike

Looks like your right limb is a little stiff about 4 to 5 inches from the handle? Other than that it looks pretty sweet! What draw and draw weight are you shooting for?
-
Oh yeah I'm shooting for 55lbs@28 it's still a bit over weight.
-
With a 60 inch, un-backed, stiff handled ,HHb stave ,that weight and draw are pushing it.... You might get away with 55#@26"
-
Thanks I was afraid of that. Well maybe I'll just have to learn to shoot a little shorter draw. Another question I have is when I measure my draw length I measure to the back of the bow but when measuring draw on the bow your measuring from the belly side of the handle right?
-
ok first off i gotta ask is ur lower limb longer thaN THE TOP ? I SAY LEAVE THE RIGHT LIMB ALONE THE LEFT NEEDS THE WORK GET A 4 IN TILLERING GIZMO TAKE OFF WOOD ONLY IN UR HIGH SPOTS I USE SAND PAPER WHEN IM THAT CLOSE AND THAT SHOULD EASLIY MAKE A 55 # BOW HHB IS DAMN TOUGH STUFF IV MADE A 58" LONG HHB @28 PUSHIN 60 EASEY BROCK
-
The lower limb (one on the left) is an inch shorter than the top. And what's messing with me is the way the top limb naturally deflexes straight back off the handle and the bottom limb naturally reflexes for a little ways off the handle so I think it's giving an optical illusion. But I don't know enough to be confident in what I'm seeing. So I appreciate everbodys input.
-
Looks to me like you need to flip the left/bottom tip a little more to match the right limb. Then get a little more bend in the same mid limb should even out on your tiller. But i'm no pro just how it looks to me. I think it will take the 55# no worry but again I'm no pro.
-
It is generally excepted to measure from the back of the bow for selfbows . It is just adding confusion to do otherwise .
Your bow is a little short for the draw Length you are wanting .
that does not mean you cant do it ,just makes it a little harder and you will most likely end up with more set than most folks want to ! some folks like that gull wing look .
You are doing a fine job ! It could have been easier if you had straightened that stick be for you started but you are allmost there now so have fun !

You are right to point out about the deflex/reflex out of the handle. If you get another stave like this remember it's best to have the lower limb deflexed/upper reflexed if thats your choice otherwise try to even them up a little before tillering.
I think it's looking good so far but it may help to get the tips at the same angle. Slowly does it from now on. Lots of exercising after any wood removal. Hornbeam will respond very well to heat treating and it may be a good idea to do it now and fix the tip and maybe also even out the limb shapes out of the handle whilst it's hot.
-
Well thanks everybody for the advice I think I'm gonna start by trying to match the tips and maybe bend the upper limb off the handle to match up the two limbs which will make it alot easier to see what's going on. This has been quite a challenge and learning experience so far everything has been done with tomahawk, knife and rasps oh and heat gun. Lol Well thanks again I'll keep ya posted on the progress. Oh and I thought I had read somewhere that it was better to have the more reflexed limb on the bottom. Not sure where I got that from but thanks for setting me straight on that.
-
Ok I fixed the lower limb tip and Reflexed the upper limb off the handle. I didn't get it perfect but it's pretty close. But while bending the upper limb a splinter lifted right on the end of the fade. After unclamping and a little sanding it's almost gone but I don't want to sand down anymore if I don't have to I'm thinking with were it is maybe a little super glue and forget it? I don't know. What do you guys think? Here's a couple pics it's the squiggly line towards the top.

I hope you can see it I realize the pics aren't very good but all I have is my phone cam.
-
i believe its lifting a splinter at that spot because of all the stresses. i believe their has been some discussion on how to design the fades to avoid this.
found it in this thread.

Lone500 you could be right on that the fade is definitely pushing it but I remember seeing this early on before I even bent it and that's why I made this fade so close trying to get rid of it which I thought I did but when I heated it up and tried reflexing it some it poped up again. It seams like a pretty shallow sliver but I don't want to sand down any further because of that reason with the fade barely going past the widest point of the limb. What do ya think I should do to try to fix this?
-
That splinter is on the belly side so it shouldn't pose a problem. Just soak it with then crazy glue and clamp it down. The tiller is not bad but get the mid limbs working a bit more especially on the left limb. Go slow
-
Looking good, What Marc said on the splinter. :)Love HHB it is some very good bow wood. :)
Pappy
-
Thanks Marc and Pappy! Will do. How far ya think I can get with it I was hoping for 55lbs@28 but some said that 28 is pushing it. Right now I'm 40Lbs@20.
-
That would be pushing it a little for me,but I am conservative on that kind of stuff,IW is tough and would probably take it. If you really need 28 inch draw I would probably go for it but would be sure I need it first.No need in pulling it any more than you need. :)
Pappy
-
Thanks Pappy that is what my current draw is but I could play around with a different anchor. And just to be clear Marc was saying to soak it with crazy glue then clamp it or soak it with something then crazy glue? Looks like he missed a word.
-
Soak it in crazy glue then clamp. :) :) I wouldn't change the way You shoot if that is truly you draw,go for it.I just here so many that say they have a 28 or more
draw length and then when/if I get the chance to measure under real shooting most aren't. :)
Pappy
-
Yeah I hear ya on that and I was hoping I was wrong it has been awhile since I checked it but just last night I stuck a piece of cardboard on my arrow drew it back let it down and and measured 28 on the nose. So I guess I'll go for it but man I hate to see this one break. From now on I think I'll go longer I was just trying to make something similar to what I'm hunting with right now. Oh and one more question what could I do to prevent gluing my clamp to the bow? I can just see myself doing that! :-\
-
I would just put a thin piece of paper on even wood and then just sand it off when you are done. It should make 28 ok,like I said it is tough wood. :)
Pappy
-
Ok thanks alot Pappy I really appreciate your help and advice.
-
Can you get a little more bend near the fades? In the pics in the first part of this thread it looks like the inner limbs are a bit stiff. A little bend there will work out to more movement at the tips increasing the draw length.
I agree about the super glue. With the crack being in the fade from bending the bow backwards I doubt you will have a problem with it. If it were on the back it would be totally different situation.
-
Yeah I think I can Pat I was working on that on the left limb especially but I'm trying to avoid that spot where it's bending hard I think I'm gonna focus on the left inner by the fade and midlimb like Marc was saying and prolly a little midlimb on the right. I've already got it looking better than the original pics. Thanks
Mike
-
you should leave it as a short draw and send it to me! >:D
It is looking real good. with the splinter, you should put some glue in it and clamp it just as the others said.
-
Listen to the wooooood ;D I think your pushing your luck some and may loose a lovely little shorter draw bow there. Either way it does grow on trees so....
No help at all was I. ::)
-
You can use a piece of plastic between the clamp and the wood, the crazy glue wont stick to that. As long as the back is pristine and you are very careful with the tiller, making the most use of the wood you have, then you can get 28" out of that bow.
-
Well first off I wanna thank everyone for the comments, advice and encouragement I really appreciate it. It's not perfect but she sure shoots nice and I'm very happy with it for my first bow. It's 60" ntn 57lbs @ 28" and shoots a 597gn arrow 155fps. I've shot close to a hundred arrows through it and I can't hardly tell the difference between it and my Fiberglass bow there is no stack and it's smooth. I can't even explain how excited I am about this but I'm sure you all know how I'm feeling. Well here are some pics.

All I have left is stain,seal & wrap the handle which I'll post more pics when that's done but it might be a while I've got a busy next couple weeks. Well thanks again everyone!
