PaperBirch D-bow - tiller help

[ojibwatbowyer]

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

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.

[nativenoobowyer86]

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.

[nativenoobowyer86]

PD -  Thanks for the tip, i think that is what i will do

Dictionary - I believe that 40-45 would have been just perfect, or an inch extra on each limb......or a knotless stave

[Baldmoose]

I believe i was the one who noticed it......

[nativenoobowyer86]

ahaha hey Mike!

correction.... Baldmoose was the one who noticed the fret   Good eye Mike

[PEARL DRUMS]

That means Mike gets to keep the bow when your done. Sorry buddy, those are rules.
