BBI recipe?getting ready to tiller...

[Schmidtster]

thats a relief, I was pretty sure I could make it work but didnt want to waste the boo if it didnt. Thanks alot I'm going to build my form next week and hopefully be glueing it up on the weekend. Please cross your fingers for me I've only done one other glue up, it turned out good but this boo is a little different to work with. I've got a ton of "C" and spring clamps that I will be using for glue up and some rubber to pad the boo.

[Schmidtster]

Well I think that I'm just not cut out to make bows. Today I made my form was doing a dry run tightening the clamps slow and even and snap!! didnt even think I had that much pressure on it and the ipe broke mid limb... This is the 3rd bow in a row that broke, two on the tree and one in the form. i have 2 successfull but underweight bows. Think I'll have to sit back and let the pro's do it, its costing me too much money for firewood.

how much are you bending it ?
 is it too much over too short a distance?
dumb question, but are you doing end clamps up before the clamps in the handle section?

dont quit, never quit!!

I'm glad I never broke a bow:) Heck I heat my house with broken bows:) Hang in there Schmidster, it will get better.

[macbow]

Keep at it. Try to learn why the failure. I've never done the dry run . With Ipe 1/2 inch I don't bend it as far as with Osage.
I have not been pre tapering, I do cut out the profile on each piece before glueing.
Clamps go on the middle first and work both directions to tips.
Good luck.

I'll give her another shot, just went on a Ipe hunt but only found some pretty shotty grained boards. gonna continue the search tommorow and if I cant find anything I know I can get some on here.

So bringing back an old thread, I have tried again and got my bow glued up, in the next couple weeks I will be glueing on the handle and tillering. just a question about tillering, I've done a couple bows but kinda was just winging it and came out with whatever weight it ended up being at my draw length. this bow I would like to hit the 45-50# mark. do you pull to your draw weight if the bow is bending good and keep inching upward staying around the weight you want until you have achieve your draw length? or do you want to stay lighter until a bit past brace height?

[Bowjunkie]

Just dont pull more than your target weight, pull 1" farther only when corrections have been made and the bow's been drawn 30-40 times to be sure the corrections register in the wood.

[macbow]

Good to see your back at it. Keep us up to date.

Hey guys as the heading says I'm now getting ready to tiller, I was wondering a few things, should I round the ipe belly before starting? And if so should it be a complete round or just the edges, also I plan on keeping the rind on, should I or can I still round the boo backing or just leave it a square edge? Thanks again for all your help!!

[macbow]

No square edges.
On the corners all of them just round them off a little as you tiller.
At the,end sand them smooth
Square edges are a splinter waiting to raise up and get ya.

[Schmidtster]

Cool thanks alot, I have to glue my handle on tonight than I will get at her later in the week!!!
