I've just about got this thing wrapped up but id like to get some opinions on the tiller. It braced at 4 1/2" in the pic and is pulling about 58# @ 28" with a full 6" brace. The pic with the full draw is 26" and the other is at 19". Thanks for the help.
The bottom pic is after scraping and is pulled to 20". How does it look now? it is down to 52#@28"

I think it looks really good. If I had to nitpick Id say there is maybe a little flat spot about 4 or 5 inches out from the riser on the right limb, but I don't know that it justifies scraping or not - especially if it's shooting good already. Maybe just make that limb the bottom limb for a bit of extra strength?
-
Bit flat midlimb on the left and a whisper of a whippy hinge about 8 inches from the tip on the right.
-
You need to draw your bow by hand now and take some pics. It will look a little different and it's the best way to fine tune your tiller the last couple scrapes
-
And ya, I agree with PatM
-
Pat and WG--If you drew that bow by hand with the left limb as the bottom would the tiller even out?
-
I don't think so. Changing the hand position will alter the amount of bend but not the way it's bending.
-
That's REAL close to hinging. Better check for chrysals, in that area by the right tip.

no chrysals. I have shoot it and it shoots good. Kinda of heavy for my shoulder but the longer I shoot it the better I get with it. I do see the hinge. I could take a bit more off I just dont want to mess it up. This will be my first hunting weight bow so im a bit scurd.

Whats worse, losing a few #s, or punching yourself in the nose if that gets any worse

right!

The only thing that ever changes for me when I move from tree to hand is a few scrapes from my top limb fade.
A hingy bow is not a bow Id ever shoot or hunt with. your better off fixing the tiller, and if you end up underweight it's not a big deal. You'll hit hunting weight on the next one for sure
-
You guys are right I'll take off mid limb and fix the hinge Friday. Have to work the next two days so I'll have to wait till Friday to work on it. I can still hunt with it down to 40# so I should be able to keep it above weight...40# would be better for the shoulder anyways. Any ideas about the best course of action with the hinge?
-
I agree with what's been said.try rotating the. Photo 180, 360 and it's plain to see.your right limb is also a bit flat on the midlimb towards the handle.i would start there to take some stress off of. The whipped area. The mids is. Where the limb. Has to. Work the most in order to keep the rest of the limb fresh and I think you may have pasted this point.hope not and good luck!sorry autogrammar thing on this phone is annoying
-
I'm no pro, and you have gotten some good advice. That being said. I might take a few scrapes off the inner third of the right limb. That might take the stress of the hinge area. I would also hit the mid limb area on the left limb a bit. Then re check your tiller. Just my opinion. Like I said I'm not a pro. Patrick
-
Show us an unstrung picture now. A still working hinge on a wood like Ipe is more forgiving than a damaged hinge on a less compression strong wood.
You can probably still balance everything and pike it a tad to boost the weight once everything is even.
-
I agree with Pat. It wont require much draw weight to right the ship.
-
Here is the unbraced pic.
-
Top pic is from the first page with the hinge. Bottom is after scraping. Currently after scraping it is down to 52#@28". It was 58#@28"
-
Left side is nutz, right side is still a bit whippy. Take 10-15 scrapes right off the center 4-6" and see what she says.

Take 10-15 scrapes off the right limb? And is the left ok or do I need to take some off the left too.
-
Left is gorgeous, but after you get the right corrected you MAY have to scratch a bit off the left to balance the bow again.

If you need to balance it out be sure to scrape even strokes full limb on the left side. Patrick
-
Ok hope this is it. Pulled to 20" 28" and braced at about 5" I think I measured wrong it is now at 55#@28".
-
Still flat in the center on the right. If you really look you can see it at brace and drawn. It doesn't have that elegant line your left limb does. Look for balance and equality between the limbs, every inch of each limb. And trust me, you wont miss that draw weight when start nailing the tiller on a given bow.
-
Also look closely at your unbraced pic...you can see it took a lil more set there at the hinged spot...thats a sign telling you it was working more there...and you pulled it way further than you should've before correcting it.....never pull further once you see a flaw regardless of how much weight your pulling. You should've caught that at brace and not pulled any further until corrected
-
Looks pretty good except for the middle on the right as mentioned above. Your fades also seem to be doing a lot of work....
-
Am I blind? Both limbs looks the same to me. Set is slight at 1" @ rest and 1 1/2" after unbracing. I hate to sound like a broken record but what do you guys think?
-
How bout now? I apologize for my drawing, never did it before.

Ok 4-5#" of right limb. Sorry
-
According to pearls drawing, it might use a few off about the same spot on the left limb as well. JMO Patrick

It's hard not to get frustrated but I'll never give up. I dont get alot of time to work on them so its takin me longer to learn. I think its close I've takin some off both sides. Its looking pretty good. I may have it today I hope. Im a perfectionist so I think that why I have broken so many. Thanks to all of you for being so patient. I want to post a finished bow that lives up to y'alls standards.

Yes I've been where you are,part of the curve I guess.my best advice is to study the brace, flip it 180 and repeat.you could start by placing the back against a flat surface (like a door frame or a hand rail on a deck) and measure tip height(remember to rotate the bow 180 to cut down on the varitables)and remeasure. You will be surprised at the difference even though it looks close by eye!alas IMHO. Is to bend it on the floor and flat. Spots and hinges will jump out at you with a bit of practice. Looks like it's gonna be a nice one!yes I agree the left is still a squeak flat mid.

Dude you are almost there you'll get it
