take a look and let me know so far ?
« on: December 29, 2009, 04:41:00 PM »


it's a tad heavy at 87lbs at 29 but might have to figure out how to drop the poundage.

thanks for looking ,
Scott

Could you post an unbraced picture?

The outer third looks like it doesn't work as much. I'd thin the limb in width starting at the outer third tapering to 3/8in tips. That will get them working a little more and reduce the mass of the outer limb a bit. what is the width at the tips currently? The thinning will slightly reduce draw weight too.

Thinning them to 3/8 should be best for the bow if they're at 1/2 right now. If the tips are still a bit stiff after you thin them I'd leave them that way because light and stiff is not a problem with the tips only heavy and stiff.  If the draw weight is still too high I'd trap the bow to 3/4 with on the belly vs the back. Ipe is great in compression and could take even more stress but I'd go slow and only trap as much as you need until you get the desired draw weight.

Looks like you can pull the weight OK, I don't think I could. Taking wood off the sides has much less effect than taking it from the belly.

Looks like most of the bend is in the first 1/2 of the limb length. If you imagine the limb marked in 4 equal sections, I would take wood off the belly of the 3rd section out from the handle. Stiff tips are good, but the 3rd quarter needs to be bending some.

Very nice looking bow, good work.

Shaun part of what you see it the reflex deflex design of the bow. But I do agree that the outer 1/2 or 1/3 needs to bend more. Thinning from the 1/2 or outer 1/3 mark down to 3/8in tips should do a lot. If they're still way to stiff you can go down to 1/4in tips and use back nocks.  Taking wood of the belly will reduce the strength faster but won't take as much wood.  If he gets to 3/8 or 1/4 in tips I wouldn't worry if they're a bit stiff.  If the tips end up 1/4in wide and stiff the bow will have no problem performance wise.

Scott, now that I look at the bow. I would actually thin from the inner third mark down to 3/8in tips and if it's still too stiff thin from the outer third mark to 1/4in tips.  The reduction in tip mass will reduce handshock, reduce noise, and increase speed.

thanks guys did thin the tips last night from the outer 3rd to 3/8 tips and took a pic at full draw but can't see any differance but maybe a slight more bend.
i hate to take more off the belly it is getting pretty thin now right at 1/8 in thick .
see i didn't taper the ends of the boo or ipe, thats what i get for not paying more attention .
would like to try an arrow through it but it's been about 25 degrees here and from what i hear that could cause some problems .
but am game at trying anything  , once again thanks for the advice  keep it coming ,

I wouldn't take any more off the belly. What I'd do now is taper from the outer third to 1/4in tips. You will have to use back nocks but that won't be a problem.  A back nock is a nock filed in the overlay on the back of the bow and no grove filed on the sides.  If the tips are stiff and 1/4in wide the bow will have no problem with performance.  If it's still too heavy I'd trap the belly to 3/4 the thickness of the back. If that doesn't work I'd go to 2/3 and 1/2.

1/4in tips are not too small. They make the bow super quiet and free of handshock.  I use 1/4in tips on most of my bows.  You just have to use back nocks.  The smallest I make my tips is 1/8-3/16in but that's on static tip bows.  1/4-5/16in is very good for longbows and working recurves.  I do think shooting it first before you change anything is a good idea though.  Could you post a pic of the bows new profile and one from the back?  What's the draw weight on the bow now?  BTW on the next bow I would not thin the bamboo or hickory but just use wider fades and 1/4in tips.
