this is my first D-style bow and i am not really sure what the tiller should look like, it is 59 in NTN with the bottom limb about 1/2 in shorter an stiffer than the top. the bottom limb is on the left in the pics, there is a decent wobble in the top limb that is kinda messin with me :)
-
I hope some of the experienced 'D' tillers (like Ken, George, Rich) answer soon, because that is what I plan on making my 'D' bow look like.
-
That look spretty nice to my eye.
-
this is 52# at 24. i think there is enough string angle to get 26. about an 1 1/8 of set so faar
-
You could heat flip the tips to make the draw to 26" a little more comfortable.
-
I agree with Bevan on the tip flipping.
-
Im no expert on D tillering but it looks awful good to me as is.
-
Tiller looks great to me. I say keep it as is at 52#@24".
-
you dont need help on tiller , i think you got it !
-
That looks great to me!
If you're concerned about string angle and draw length, you could flip the tips as advised earlier, or get just a bit more bend in the middle.
Can't wait to see it finished up!
-
Not that it really matters, but what kind of wood is it?
-
Nice looking bow! Tiller looks good by my eye

This is very good tiller. I wouldn't touch it any more. If we talk about perfect tiller then you should heat treat (just a little) two softer places (just a little bit): places where meets middle and outer third on left limb and middle of right limb. But this is just to improve tiller to perfection, I think it is good enough now.

thanks for the extra eyes fellas, i appreciate the help, i didnt know where to scrape anymore :) i guess that means its done :D
Bevan R - it is paper birch, i am suprised by how light in the hand it is. i always considered birch to be very dense and heavy but, like it says in the TBB's, its lighter than anything i have used. Elm being second.
Matt S, Pearl Drums, Bevan R - im ok with 25" for draw and 54-55# so i think i will pull it the extra inch and call it good.
Druid - i think you are right about the soft spots, i thought i saw them but it wasnt enough to put the scraper to it. One of these days ill print out a pic of one of your amazing bendy handle bows and put it by my bench for reference :D
-
Looks good. You could get a couple more inches of draw by letting the handle bend a bit more
-
Matt that bow is sick! Take it in the back yard and take some shots with it, the weather here is good so it must be even better there. I lost a few arrows in the snow bank about a half hour ago myself ;D
-
I don't think you need any help with that tiller! If anything , I need you to teach me to tiller! Josh

So i took this one over to a friends place and sanded it up and got it ready to stain the bone whiteness of the birch, when i noticed a small crack thhat i took to be a tool mark, turns out it is a small fret on each edge right in line with a knot on the upper limb. I think i caught it early because it is still pretty small. about 1/4 inch on each edge, i did what i could to take a good pic but its so friggin white!
thought it was a wierd place for a fret, i left the interior of each midlimb a little stiff to ease the strain on this kknot in particular.
there was a hazel buildalong a while back where this same thing happened, and he fixed it with a rawhide patch to ease the local compreession. would this be the best option?? i apologize for not remembering the name of buildalong, it was really good and he deserves credit here ;)

I personally use Marc's bows printed, hanged in my cabin, for model how perfect tiller should look like. Thats good idea.
-
Dazv - u bet, thats the one :) Gordon of course!
-
I just HATE seeing that. Hopefully you can get her moving along again. Nothing worse than thinking you have a good one cooking and then something like that takes your breath away, at least it does mine. Sorry to see it.
-
ya i wasnt too impressed >:( but these things happen, i have never had to deal with a minor fret b4, all that i have seen were terrible chysalled sections that basically wrote off the bow. i kinda feel like this might be salvageavable? maybe just wrap the whole knot and 2inches either side. i have some really thick moose rawhide and some paperthin deer rawhide that i could use, sinew as well.
-
this is where the knot is located on the limb, i deliberately left it slightly flat in that location :S
-
I have tighly wrapped silk thread and TBIII around mini fractures before. It stopped them in their tracks and no more formed. The basic idea is to stiffen that tiny area up slightly, it doesnt take much. The silk thread and glue adds more stiffness than you may think. It forces the few inches before and after the fret to work a touch more, alleviating more forming. An extra thin osage belly lam would also work. Cut a strip 12-14" shorter than your bow and fade it towards the tips. Maybe .060" thick or so.
-
Unfortunate to see that, its a very nice bow. If the draw weight had been lower(40-45#), do you think this still would this have happened? Just curious.
-
PD - Thanks for the tip, i think that is what i will do :D
Dictionary - I believe that 40-45 would have been just perfect, or an inch extra on each limb......or a knotless stave :P
-
I believe i was the one who noticed it......
-
ahaha hey Mike!
correction.... Baldmoose was the one who noticed the fret :) Good eye Mike :D
-
That means Mike gets to keep the bow when your done. Sorry buddy, those are rules.
-
The bow looks really good. Hope the fix works for you.
-
stinks when that happens,the bow was looking sweet too! I've got a sweet birch sapling that I'm goona start work on soon and now I'm nervous about knots in birch! I have built a couple already and I can say this,be careful if you back it,I used hickory to back and it was so strong it crushed the belly like an accordion!! I think I'm going to try cherry next time! I hope you can fix er' Gl,Ron
-
ok so shes all patched up, i scraped b4 and after the patch and a couple even ones down the opposite limb. lost an lb tho 53 at 24.
-
Just saw this. Looks like a real nice bow to me. Good save.
George
-
looks like a great bow to me.
-
Good save,that's a good looking tiller to me. Hope it with stands the test of time and many arrows. :)Looks like it should. Nice work :)
Pappy
-
Nice bow. Congrats on saving it...so far...knock on wood... :D
-
I've found that knots, despite how the tiller looks, are a likely place for chrysals to show up. Especially on weaker woods. I'm sure we all got a favorite bow tucked away somewhere, that has a couple chrysal patches, that we just don't tell nobody about. Tim Baker said that it's still a bow until the back fails. I think if you noticed alarmingly increasing set in that area as well as dramatic draw weight loss, then there would be cause for concern. Or they kept increasing or more started showing up. But as long that doesn't happen I personally would be very happy with that bow. :laugh: The tiller looks great to me from the start.
-
thanks alot toomanyknots, i will take this into consideration in the future. I plan to build a few more, from larger trees to permit wider limbs :) so long as it shoots straight, im fine with it :D
