Title: Recurve build limbs looking better
Post by: heartlandbowyer on February 20, 2014, 09:15:00 PM
Trying a new recurve design, I have very limited curve experience so this is a shot in the dark for the weight. If all works out bow will end up 54-56 in between 50 and 60lb. Added a 7 in .0055 per in tip wedge not sure if it will make the tip static but it will stiffen it up a bit.

Bocote back veneer from Idaho Curt give away, zebra wedge, core tuff and boo core and brown belly.

Adding pics in a min.

Got a little more done tonight just need to decide on riser. Maybe bocote and zebra to match wedges.  (http://i1336.photobucket.com/albums/o641/cengert74/IMG_20140221_170025_462_zpsfc599aa4.jpg) (http://s1336.photobucket.com/user/cengert74/media/IMG_20140221_170025_462_zpsfc599aa4.jpg.html)   (http://i1336.photobucket.com/albums/o641/cengert74/IMG_20140221_213429_794_zpsdcde4825.jpg) (http://s1336.photobucket.com/user/cengert74/media/IMG_20140221_213429_794_zpsdcde4825.jpg.html)   (http://i1336.photobucket.com/albums/o641/cengert74/IMG_20140221_214053_933_zps0151aa1f.jpg) (http://s1336.photobucket.com/user/cengert74/media/IMG_20140221_214053_933_zps0151aa1f.jpg.html)

Oh yeah baby... love that bocote!
The right block is phenolic?
Title: Re: Recurve build limbs looking better
Post by: heartlandbowyer on February 22, 2014, 06:05:00 AM
Yep Moe phenolic, gonna do a little mach-up on some dummy risers to see about #age and length since it's a new design.

Stay tune I've got my fingers crossed   :campfire:

Going to be a sharp looking bow.
Title: Re: Recurve build limbs looking better
Post by: heartlandbowyer on February 23, 2014, 09:00:00 PM
Getting closer it's almost a bow, cut out sight window, drop a few lbs and start shaping her out. Got limb tracking good now and she pulls smooth to my draw 29. Should be running some arrows through her in the next couple days. 56 in with just a tiny bit of movement in the tips.

Shes a shooter ran some heavy lodgepole pine through er tonight. String is laying good after the shot, quick and pretty quiet too   (http://i1336.photobucket.com/albums/o641/cengert74/IMG_20140224_180230_764_zpsf91346c0.jpg) (http://s1336.photobucket.com/user/cengert74/media/IMG_20140224_180230_764_zpsf91346c0.jpg.html)   (http://i1336.photobucket.com/albums/o641/cengert74/IMG_20140224_180245_831_zps6e8aca43.jpg) (http://s1336.photobucket.com/user/cengert74/media/IMG_20140224_180245_831_zps6e8aca43.jpg.html)   (http://i1336.photobucket.com/albums/o641/cengert74/IMG_20140224_180314_927_zps1307564f.jpg) (http://s1336.photobucket.com/user/cengert74/media/IMG_20140224_180314_927_zps1307564f.jpg.html)

Looking nice Cory - going to have to try one of those - I love static tip recurves!

Hi Cory!
Great bow, great work, it' a beauty   :thumbsup:  
Can you tell us the length and the angle of the limbs?

Greetings, Peter
Title: Re: Recurve build limbs looking better
Post by: heartlandbowyer on February 25, 2014, 07:41:00 PM
Peter the bow is 56inch nock to nock, string is 53 in. Riser is 13 inches with 4.5 in limb pads at 10deg.

Thanks
Cory

Really nice limb design and beautiful bow, in my humblest of opinion, the limbs are showing just a  slight amount of hinge just past the wedge tips. If you have any more weight to reduce, try taking it mid-limb on out, it will help reduce the fatigue point.
Title: Re: Recurve build limbs looking better
Post by: heartlandbowyer on February 25, 2014, 10:08:00 PM
Mark, good eye, already started to do that and it's getting better I've got a little more wiggle room as limbs are still just wider than 1.5" and I'm right at the high point of my shooters weight.

I've already been been thinking about the next one having a longer wedge and a longer more gradual taper. If I can't get the stress point out of this one she will go on the R/D shelf. I will still have a good riser and will just have to glue up some new limbs.

Totally new designs are a struggle on the first one off the form for sure but if ya wanna make em your gonna break em.

Post by: Buemaker on February 26, 2014, 08:41:00 AM
Overall very good, but I hope you do not mind if I disagree with you on one point. I would not make the wedge longer, but rather shorter or thinner at the last couple of inches in order to get it flexing a bit closer to the handle. Wood combination is very nice. Bue--.
Title: Re: Recurve build limbs looking better
Post by: heartlandbowyer on February 26, 2014, 11:09:00 AM
Bue, nope I don't mind, that and experimenting is how I got to my current longbow design. I know I definitely need a less steep taper on the wedge. Right now it is only 8.25 in long. The bow already has a pretty short working limb so you probably are correct when you say not to lengthen the wedge.

Right now I'm just I'm just running 1 taper in the stack, I may try to incorperate some kind of core lam taper and adjust the wedge taper for a better transition from wedge to limb. I think that will help the fade work better without the stress.

Post by: Buemaker on February 26, 2014, 12:06:00 PM
No reason to put the limbs on the shelf, the bow should last for many years and I think she is a fast shooter. I have seen bows fron the 1960s and 1970s with a limb design like that and many of them are still around. Bue--. Sell it to a flight shooter.
Title: Re: Recurve build limbs looking better
Post by: carpin'mark on February 26, 2014, 01:33:00 PM
Yep, new designs can be tricky, all you can do is go with what you know. I agree with Bue, I dont think its a 'shelfer' by any means, its not bad past the wedge, you just dont want it to go any further. Worst case, you may go below target weight and possibly lose some of that nice static at the tip on this particular one as you slim it down.
The wedge length if fine, maybe heavier taper to push the flex past the wedge tip a little or less material(if any) removed at that point.
It's a great looking design, a few minor details and its gonna be a thumper!
Title: Re: Recurve build limbs looking better
Post by: Al Dean on February 26, 2014, 06:46:00 PM
My 2 cents worth.  I think your limb design is good but not for that riser.  I would reverse the wedge and go with 20* limb pad.
Title: Re: Recurve build limbs looking better
Post by: heartlandbowyer on February 26, 2014, 07:14:00 PM
Al, I've thought a bout reversing the wedge but only for aesthetics. I'm only at 10 degrees I took a pic at 20 and I think I would loose a lot of my preload and that would hurt the bows efficiency. I think I would have to thicken my stack by half to get my desired weight. I could be wrong thought since this is really my first curve.
Title: Re: Recurve build limbs looking better
Post by: heartlandbowyer on February 27, 2014, 07:58:00 PM
Bue and Mark! Did some more work on the limbs and got them decent, still tracking good and at mid point of shooters weight I think she will make a swap bow after all. What y'all think?   (http://i1336.photobucket.com/albums/o641/cengert74/IMG_20140227_164750_524_zps07076da0.jpg) (http://s1336.photobucket.com/user/cengert74/media/IMG_20140227_164750_524_zps07076da0.jpg.html)

Very nice Cory. I'v decided to stick with limbs you built me. My back muscle is building up. BUT that recurve is looking really sweet, to bad its not a lefty.
