John, you have a hinge forming on the right limb just past the second verticle line. Stay clear of that area for removing any more wood, and also work on getting the limbs working a little closer to the fades. There is a long section of non-bending by the handle area. The left side is looking good, it could bend a little more at the fade as well.
-
yup :)
-
John how about a picture of the front view. But yup what Keenan said.
-
Thanks Keenan, i see that now, there is a knot just to the left of that hinge that has been giving me trouble. :'(
Dana i'll try and take one tonight.
Thanks
-
Ditto. and deffinantly needs more bending around the fades.
-
Tonight i will work on the fades. It's amazing how much better you can see things when it's on the computer screen :D
-
I agree John, Sometimes I will take several pics will tillering and study on the computer to see what I can't see in the shop. I now see that knott that you are talking about.
-
John the reason I asked for a front view picture is that the front view profile should dictate the tiller.
Not every bow needs to bend right up to the fades. If your doing a parralel limb for about 2/3rds then tapering to the nocks
I don't believe it has to bend a great deal into the fades, with a profile such as that it should be more eliptically tillered. slight
bend in the inner limbs then more bend towards the tips. Now this is just my opinion, but too many times I see "Its not bending in the fades enough"
Different tillers for different profiles, I believe it was in badgers chapter in TBB vol 4. I'm sure lots of folks won't agree with me but I would probably get the outer limb bending more and leave the fades alone at this point. Not trying to confuse ya John just offering a different opinion :)
-
Good thoughts Dana but the string angle will increase considerably by having the tips bending more. If the limbs bend more at the fades, the string angle will not change as much. As you said, differing thoughts and none nessesarily right or wrong.
-
Here are a few pics of the knot.

Thanks Dana.

That one differently needs to bend more in the fads and the outer 1/3 also ,it is only bending the middle 1/3.I usually leave the fads to last but at 23 he is at the last.time to get the rest bending,and like said watch that spot on the right limb.Probably won't take anymore off that. :)

What I'm thinking here Keenan is its a 70" bow and a 28" DL that leaves a lot limb to work with. It should bend into the fades but only slightly, if you get carried away at the fades and get a little set there it will translate into lots of string follow at the tips. Also if you leave the very tips stiff I don't see string angle being an issue on a bow that long. Good topic for an evening around the campfire at Pappy's eh :)
-
Great explanation Dana, and great campfire discussion to boot. ;)
-
Keenan mirrored what I was going to stay. I think more near handle wood should bend too. Pulling that stave to 28 in as is will probably result in a break. Jawge

Did some scrapping on this one over the weekend, got it out to 27" shoots good, still looks like a little bit of a hinge on the right limb, but i think that knot has something to do with it. Anyways i'm going to leave it as is and sand it down and figure i'll get my 28" s once i'm done sanding.

Sorry the picture is a little blurry, but it's hard pulling it back and trying to take a picture :D

Hard to say for sure but I agree that the right limb doesn't look right ??? Have you shot it much yet, if so do you see any frets or
more set in the right limb than the left? Also how long is it nock to nock, the string angle looks like its at 90 degrees so I expect there is some stacking.
I still think a eliptical tiller would have better suited this bow. Not knocking yer bow John just offering my opinion and hell I'm probably wrong anyway ;)
If its stable and shoots an arrow and your happy than go forth and have fun eh :)
-
Dana, It's 68" ntn the right limb took about 1/2" more set than the left. I haven't shot it much since it's a left handed bow, but i was shooting it yesterday right handed with a glove on. I'm going to finish it up. Give it to my Uncle and let him shoot it. If nothing else it will look good hanging on his wall and i can start another one for him, he lets me cut trees down on his land ;D
Thanks for the input.
-
John you could try flippin the tips a little that will help with the string angle. And yup there's always another bow waiting to be built :)

Full draw pic. 45 @ 27"

Nice Bow John....it does look a bit off on the one Limb....but if you are happy with it....and it is shooting good....shoot it!! One Question though.....Why such a big Handle area? could make it less and get more Limb moving with the same design....just a thought.... O:)
-
Thanks Mike, Not sure why the handle turned out so big ??? One of those learning things i guess :D
-
I like it John. Good job! I like the oversized handle too. It could give you a natural overdraw. ;)
-
that's a fine bow John! You did correct the tiller very well, and since there's still this slight hinge, you probably kept some drawweight. Well done ;)
you may want to get that hinge totally out, and temper it to regain some drawweight?
a tip on the handle, just make the handle itself 4-5" long, and the fades 2". this is big enough for your hand, and tiny enough to absorb alot of stress ;)
for some reasons long handles seem to add stability tho, but if you go for long handles, you probably want to make the bow a little longer too :)

Good job John looks much better :) Bet its fun to shoot.
-
Thanks Guys. I only shot it a few times. It is for my Uncle and he's left handed, so i was shooting it right handed of the knuckle. I thought it shot good. I give it to him this Sunday, will see how he likes it......
Thanks ! John
-
Looks good John, get yer Uncle to pose for a picture, tell him its mandatory ;) :)
-
I'll get that "south paw" to pose for a photo. :D
