(can't sleep at night been thinking about for a year crazy had to do it Static Recurve lever what the F bow) :knothead:
I did a lot of measuring of this bow
This is not my design, I just like it.
This was my inspiration for building this bow
The nocks are 8" in front of the grip
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0459_zps99d32ed2.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0459_zps99d32ed2.jpg.html)
64" NTN
7" levers
15" riser 7.5* limb pads--7-1/2" long wedge .275 butt
.280 stack
2-.030 black glass 1-1/2"
1-.030 uni-weft glass
2-.095 butt .002 tapers bamboo floor

So let's get started, sanding the lams on .002 sled to .095, Thanks kenny
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0429_zps918664d6.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0429_zps918664d6.jpg.html)
Ready for smooth-on
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0430_zps6cd5637b.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0430_zps6cd5637b.jpg.html)
In the form and in the oven for 4 hours
The radius on the form at the recurve is 2-3/16"
Lots of dry run's to get the lam's closed at the recurve
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0428_zpsffae2a6f.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0428_zpsffae2a6f.jpg.html)
both limbs out of the oven and cleaned up the sides, glue joints look good
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0431_zpsf4506230.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0431_zpsf4506230.jpg.html)
sanding the limbs parallel to 1.40 wide
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0432_zps88744eb7.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0432_zps88744eb7.jpg.html)
I made two sleds to sand the limb profile
1st sled .005 taper
2nd sled .010 taper
1st the .005 and then the .010 sled
I'am sanding the taper up the limb stopping at the riser. The limbs will be 1.400 wide for 3", taper .010 per inch total 1.230 at the lever fades (The levers will be 1/2" wide tapering to 1/4" at the nocks

That is gonna be a speed demon by the looks of it!!!
-
Very cool. A true blue static recurve. I love it.
-
Excellent. I have the same bow design drawn out when I first saw it as it is such a wild design. Nice form you have made and very much looking forward to seeing the results.
-
Can't wait to see the braced pic.
-
Ok I'm in. Let's see some more!
-
Wow that's going to be cool! Can't wait to see more.
-
Now to make the static overlays I STARTED with 10 layers of .050 osage each one 1/2" shorter than the last. I then drilled a hole in the center of each, and a nail to locate.
The nocks are going to be 1" left and right of the nail
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0435_zps4d3459bd.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0435_zps4d3459bd.jpg.html)
And the form for the overlays
after many dry runs the gaps are closed
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0461_zpsfcee1d09.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0461_zpsfcee1d09.jpg.html)
Taped off the back and belly and glued everything with smooth on
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0436_zpsfc6382bd.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0436_zpsfc6382bd.jpg.html)
Out of the form, looks good
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0437_zps7b325d0e.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0437_zps7b325d0e.jpg.html)
Ready to gule the overlays to the limbs
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0438_zpsa419b3cf.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0438_zpsa419b3cf.jpg.html)
I narrowed the tips to 1/2"
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0443_zps23e5c49d.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0443_zps23e5c49d.jpg.html)
And the back of the tips are angled to 1/8" ( Triangle shape)
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0448_zps51652110.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0448_zps51652110.jpg.html)

I do think I'am crazy sometimes
-
Time to make the riser
15" long and 7.5* limb pads
Bubinga and Osage, black fiber glass and 1/8" strips of bamboo. Nothing special just stright cuts
I used a sled for the table saw
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0460_zpseeeb4c42.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0460_zpseeeb4c42.jpg.html)
I cut the limb pads on the Bubinga before glue up
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0434_zps9282b983.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0434_zps9282b983.jpg.html)
Drilled a 1-1/8" hole for the grip and started sanding with the robo sander no guide on the drum
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0454_zps40679661.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0454_zps40679661.jpg.html)
and then a 3/4" drum
Looks more like a riser now
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0455_zpsa043e63e.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0455_zpsa043e63e.jpg.html)
Now I going to drill the holes for the nock inserts
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0444_zps9efd7455.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0444_zps9efd7455.jpg.html)
I cut the nock groves and sanded every thing smooth
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0450_zps5a3df0d4.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0450_zps5a3df0d4.jpg.html)
And here is that Brace you wanted Pat
No issues of limb twist
The sleds I sanded the limb width on worked nice.
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/100_0445_zps17042b92.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0445_zps17042b92.jpg.html)
Next I'am going to remove some more mass from the tips

Second page?

Thanks for posting the pics! I'm following this build along..
-
Next I'am going to remove some more mass from the tips
I used thread and string wax and then pull to full draw, if the string is loose then it's flexing
I used string for the picture

I chased 3 layers off, one at a time and reworked the tip fades
[URL=http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/sixtyfinish/100_0472_zpsc367bd32.jpg.html] (http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/sixtyfinish/100_0472_zpsc367bd32.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/100_0453_zps3660de4a.jpg.html)
reduced the last 2" down to 3/8" at the string groves and 5/16" at the nocks
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/sixtyfinish/100_0462_zps7f51ed55.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/sixtyfinish/100_0462_zps7f51ed55.jpg.html)

I finished sanding every thing and put 6 coats of Helmsman Spar-Urethane semi-gloss, I still need one more

All finished
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/sixtyfinish/100_0468_zpsdf664144.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/sixtyfinish/100_0468_zpsdf664144.jpg.html)
Braced 7-3/8"
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/sixtyfinish/100_0470_zpsbe605c02.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/sixtyfinish/100_0470_zpsbe605c02.jpg.html)
Draw to 28"
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/sixtyfinish/Snapshot17-3-20142-17PM_zps3a4918da.png) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/sixtyfinish/Snapshot17-3-20142-17PM_zps3a4918da.png.html)
The bow finished up 42#@28"
This is my first one to make.
I did not have any issues of limb twist
I am pleased how it turned out :bigsmyl: :bigsmyl:
I shot some Lighter arrows at about 22/24" draw :jumper:
When I build the next one I want to put the wood (static tips) between the fiber glass as a core.
I SHOULD BE ABLE TO MAKE THEM THINNER ?
WHAT DO YOU THINK ?
(http://i1293.photobucket.com/albums/b593/osagemark/sixty%20four%20static%20recurve/sixtyfinish/100_0472_zpsc367bd32.jpg) (http://s1293.photobucket.com/user/osagemark/media/sixty%20four%20static%20recurve/sixtyfinish/100_0472_zpsc367bd32.jpg.html)

I smell a reverse-Grumley around here. Very cool bow. Especially like the bridges. That might be the coolest and most unique glasser Ive seen.
-
Great job! I think if you insert a tapered wedge in the core, you could make it much thinner. I would think that even an .080 thick wedge, tapered down to nothing inserted in the limb core would make the tips static.
-
That is a very interesting result. Should be a snappy shooter.

This is my 3rd glass bow so i do need some advice.
from the nock to the bridge is 4"
will the glass on the outside make that much difference?
Thanks
Thanks pearl
-
The sharp hook you have in the limb itself makes it almost static, therefore I think you could get by with a just a thin wedge in the stack to fully stiffen it. Having the wedge on the inside of the core will be structurally much stronger.
How does it shoot?
-
A new place to pick up some speed would be a larger string bridge and possibly tunçs on your string. I know that swapping an integral loop string for one with tied in loops improved my horn bow's cast and manners.
I'd love to try that bow. I shoot a horn composite currently and I've wanted to find a bow that would handle moisture while hunting without giving up thumb style and its benefits. You might just have something there.
-
bjansen Thanks I had to order some arrows for it.
I will keep you posted
when I get the arrows I am going to get some chronographs speeds
halfseminole What are tungs on the string
-
http://heartwoodbowsonline.com/wordpress/?p=489
That explains a little about it. My composite only really works right with them.

I saw that before but did not read
COOL Me Like

Looking real good so far. Thanks for sharing.

Pearl
what is a reverse Grumley
-
Just to let you guys know, this bow is here with me, and I'm working on an arrow heavy enough to tame this thing. However, this thing is blistering fast, and only getting faster as I work up to a 36" arrow.
Gentlemen, I mean this in all seriousness: line up for the next ones he's building. This thing is wild, and I mean that in a good way. While I'm still working on such like proper arrow selection, this thing easily outclassed my horn composite. If you like a heavy arrow, this should be your only choice.
-
Brilliant. I have a conversation with you in e--y
glad I found you. I have a feeling that I might be a customer for that lefty bow we talked about. Christmas is my time frame...might as well give myself a gift
-
Thanks
Looking forward
-
Just wow!

That looks great !Thanks for posting the build.
