This is a static tip bow I have been working on got the raw hide on 2 weeks ago & got it shooting yesterday Im going to call it done if you guys dont see any thing else & send it to the beauty shop
Its posting good chrono numbers with b50 & 530 grain arrow ,I think I will bust the 170s with Ff
Stats are 65ntn 47lb @29

The top limb looks good, the bottom is bending too much just out of the fade and a little stiff in the outer third.
-
Ok thanks Eric the outer third is 9 in. of static limb it's hard to see in the pic , this type bow can be a head scratcher for me if I flip the bow over it is almost the same looking profile & the bow measures the same at brace less the 3/16 positive tiller
-
Could be the way it's canted slightly too.Pretty good Ritch.Those numbers are A+ too with an 11+ grain arrow too.Glad everything worked out good.Congratulations.

A little too fast for you I can see, the deer is still on the run:)

-
I'd be happy with it. Should be a hunter.

very nice congrats on a nice shootin bow,, :) thanks for posting the chrono results,,its a bit of extra work, but when you keep a journal,, the info always comes in handy,, for you are someone making a bow,,

Pictures can throw things off. If you really want to see detail, look at a picture and squint, this gets rid of a lot of background and other things that confuse your eyes. I learned that in an art class I took years ago when I was learning to paint the duck decoys I was making.
-
Looks like the static outers are getting the job done well. Are the tips exaggerated, as with the molly style? , or for that matter, Is there much more to be gained with Eiffel tower or recurved style static tips?
-
Looks good. Bottom limb looks shorter?

I think that anything that lightens the tips short of breaking or instability is a good thing. That said I also think that once you get up to 170 or so the improvement come 1 fps at a time. For those that aren't speed freaks it becomes unimportant and they'd be better off with durability.

I agree entirely.

about the photo,, the camera distorts images a bit,, and the cant of the bow comes into play,,
when i hold up a straight edge to the photo,, i can see the tiller pretty good,,, and if it was my bow I would be hesitant to make adjustments made soley on the photo,, i would have to see it in person,, and study it like that,, also I would have to study the unbraced profile and the feathering of the grain,, etc etc, etc,,,,, the photo give a good general idea,, but I would not scrape wood based on it,,
if the bow was not taking any more set,,, and teh profile was stable, I would make that my key indicator,, and how the bow shoots trumps all that for me,, :)

Thanks every body Willie this bow is a half parallel half pyramid design with statics 9 in worth so the tips tapper mid limb to the tips and the static tips also tapper in thickness I did not narrow the statics in width only in thickness other then pyramid but if you weight the bow as your taking off wood its amazing how much weight are left in the tips ,with raw hide I ended up at 20.67 oz. George its the phone camera distortion there the same length , DC I was not chassing speed per say I was just trying to make a late season below zero hunting bow with the idea if I short draw from wrong postion shot or just plain being to cold I would still have good arrow speed not changing trajectory to much on 20 yard shots. I have the big brother of this bow at 68 in and going to be 52 lb all ruffed out ready for tiller it will be interesting to see the difference between this one & the longer heaver version.

Brad I posted at the same time as you but thats a good point those guys that are lucky enought to have a grided pulley system have easer go of it but every bow pic that my wife takes of me drawing looks like the botom limd is shorter & distorted maybe I will put her on a stool next time she is a foot shorter then me ,DC had a good thread on pic distortion even high grade lenses have some distortion I think pics are good for spotting hinges and that type thing but with undulations & the like can give false reads also. But its the best tool I have tell I can devolope a good tiller eye.
-
It's a PITA but I think the best is two pics, one upside down.
-
Well got the FF string on and almost shot in but here is the numbers with 11gpp arrow & full draw good release this is a 170 fps bow all day so far , I feel good its taken me almost a year & half and a lot of help from you guys to bust 170 fps plus a lot of failed bows , I could probably scale the arrow back a bit and get more but 530 grain arrow is my hunting weight !
-
Great number! I hit 173 once. I've never managed consecutive 170's, yet :D
-
That FF string has taken a while to get to stop sliping at the hitch knot Im averaging about 171 fps with my normal release Im probaby at maybe 160 arrows im leaving it strung for a couple hours to see if it stays consistent !
-
Just make a double loop string for it Ritch.Otherwise there was a thread on keeping FF string from slipping.I think just a few more wraps around the timber hitch does it.
-
I put super glue on the timber hitch as well,,and tie a knot at the back of the hitch,,,,, that wont slip past the knot,, congrats on your bow,, nice shooting
-
Thanks Brad I tied the knot it stopped, when I get every thing dialed in I will make a double loop !
-
Beadman you are right a few more wraps will work too,, :)
