well its been awhile since ive made a bow
been to bust knapping i guess
so right before x-mas i roughed this one out
now ive got it at a full brace and pulling about 20" and 40#
the stave started with some prop twist and i think its playing tricks on my eyes
so i thought i would take and post a pic with each limb at the top and get your folks opinions on it
in both pics the lower limb looks off compared to the upper,keep in mind in the second pic the bow has been flipped over
so what was the top limb became the lower limb in the second pic
let me know what ya'll think
sorry i dont photograph well ;) ;D
thanks for peeking

i suppose i should have told ya'll
its hickory,64" ntn
dont really care what the draw weight comes in at
if its to light to kill turkeys with,then i'll give it to the wife for a target bow
or one of the neighbor kids to torment their pets with lol

It is hard to say, I cant see the bow past the ellipse. What we have here is an ellipse eclipse.

Looks spot on to me. T.

lookin good. maybe a little more bend at the fades? dont know if its that big a deal maybe just leave it.

it's not far off.
to me it looks as though the top limb is a little stiff in the first two thirds (however it's in both photos, upside down and right way up), so this may be because you are (or so it seems in the photo) drawing from a little high on the string, which is in affect making the top limb look stronger. you can see that the top limb is leaning back towards you more than the bottom limb, represented by the handle not being verticle.
is there a shelf cut in? if not you can grip the bow higher. if there is a shelf try drawing/nocking from lower... how does it shoot?
-
top limb is a little stiff with my eyes, looks good like the face pic.
-
I agree with otis, you are gripping the string rather high, check that first. If you are gripping in the middle, it does appear that the top limb is stiff.
-
top limb in which photo's?
keep in mind,the top limb in the pics(in both sets of pics)becomes the bottom limb in the second pics(in both sets of pics)

in all photos. thats why i think you need to adjust both hands and recheck before doing anything to it. try dropping you string hand 1/2" and raising you bow hand a similar amount. or anywhere in between. take some more photos and put them up.
-
otis, will do
might not be able to get pics up untill tomorrow though
thanks
-
Must be where you are gripping the string then. ;) Try what otis said.
What we are seeing is a lot more belly on the limb on the bottom in both photos. It gives the appearance of that limb bending more. It could be that the camera is higher than center of the limb. I have discovered that if you try to keep the camera the same height as the bow handle it makes it easier to see tiller in photos.

sailordad,
Threw a ruler up against the picture and the top string length measured 7.2 cm and the bottom string length was 9.0cm which would mean your right hand is too high. The limbs look the same in both pics even though you flipped the bow over so I'm guessing that the tiller is not too much off at all....just that your draw is consistant in both...but a little high.
half eye ;)

I'd say the top limb is stiff.

after reading your post,i did the same thing
you guys are right
i am consistantly drawing high on the string
new pics coming tomorrow

sailor,
depending on the limb lengths and strengths it may be helpful to adjust both hands. is there a shelf cut?
if you are shooting off the hand, then adjust both hands until you get the best balance. you are looking for;
even tiller
verticle handle
no handshock
and want the arrow knocked somewhere about 3/8"-1/2" (or there abouts) above where the arrow rests (on a shelf or bow hand)
flipping the bow upside down for photos causes it's own dramas. you need to both; draw it from the same spot on the string when upright and upside down, and also, push on the handle in the same place when upright and upside down. do it the right way up first and mark the string where you drew from and the handle where the pressure was (usually the pad at the bottom of the thumb or the webbing between the thumb and forefinger). you can use a small piece of electrical tape to mark the spots. when you flip it you need to be applying pressure to the same spots.
-
otis,thats good info
right now the handle area is quit meaty as i plan on cutting a shelf on this one once the tiller is finished and
it shows me which limb it wants as the top
but i will take new phots pulling from the center or very near to it an try to get the web of my hand centered also
-
sailor,
you could hold and pull it from the centre of handle and string to get photos and choose a top/bottom, but i would be more inclined to hold it in a position you would once it's finished and draw from slightly above pretending this is the right way up. take a photo. then flip it and do the same again pretending again this is the right way up. take a photo. choose a top and bottom. and stick with it. cut your shelf, make adjustment to you tiller.
again adjusting and looking for ;
even tiller
verticle handle
no handshock
arrow knocked about 3/8"-1/2" above the shelf or where it will be.
