Just want wanted to show ya good people the first bow i really enjoy shooting... only took 15 or so to get one that feels right!
a few strange things about this bow that the first is that one limb took about half an inch more set from the begining of tillering and that limb is mutch thicker than the upper limb but was bending way more so i just tillered it how i figured it should look and just went with that.. any idea on why this was? the next odd thing is that a splinter popped up on the belly after shooting it for a while, so i put some super glue under it and called it good, seems fine but is a bit odd, onther thing is it seems like there may be a few chrysles on that lower limb that took more set and is thicker... the chrysels and splinter are in the bottome photo... anyway heres the specs
64" TTT 1.5" mid limb 7" fades and handle, 60# @ 26" 1.75" set after a long shooting session, 1.5" after resting. any critiques welcome and wanted.

With the problems that you have run into it looks to be a fine bow. I say shoot the spit out of it and build another one.
-
So do you guys think those chrysels are deadly?
-
Don't know much about splinters except a fatal one in an heirloom bow got me going here! Maybe sand out the Chrysals, seal them and if the bow doesn't break after 1k shots, it may last! :BB (SH) (SH) :NN (--) >:D (lol) (lol)! Nice bow, what wood?

Okay thanks for the advice i try sanding them out.. and its hickory, i did a few heat treats aswell
-
What should i seal them with? I have a few coats of shellac and oil/wax On it now.
Thanks again.

What wood is this?

Your tiller is poor on the bottom limb and not very good on top. I'm going to guess the compression fractures are near mid limb on the bottom. Sanding them makes it worse. They occur because that is the weakest point of the limb. So removing material will only worsen it. Get your tiller fixed and perhaps they are gone, but I doubt it. They go much deeper than you think they would. Start another bow and use a straight edge, or Erics Gizmo, to tiller it.

Bow looks good Fox. Just retiller and take some weight off top limb. Maybe turn it into 50lbs@26 and shoot the snot out of it. Stay off those compression cracks in bottom limb. Looks like a shooter.

Alright ill retiller a bit... but im not 100 percent sure the tiller is that off.. it looks like its bending more there im the photo. I used a gizmo most of the tillering prosses and worked out the limbs every time i removed wood.. but will go check again.
Thanks guys

Im not totally sure from the pictures but I don't really see anything that looks like a chrysal. The first picture after the full draw to me just looks like the grain lifting, which can be avoided if you wet the bow between sanding passes. Hickory especially seems to like doing that, and I think its not really related to the tiller. Seems to happen a lot with the porous early wood fibers.
The diagonal crack really looks like a chrysal, and it being that diagonal really suggests it is...but to me it has the jagged look of a tension break that happens when you heat treat and bend over a caul, not the crinkly look of a compression failure. Could be wrong, just offering another possibility.
And i do see the splinters too, but none of this would really worry me in terms of safety. Could the tiller be better...sure, but i bet you'd have to pull this bow really really far before it broke.

I've found that pictures can lie. Sometimes it's as simple as nocking the arrow too high/low because you're in a hurry using the camera timer. Some cameras distort the top and bottom of the pictures a bit. Try flipping the bow over and taking another picture. Take care to nock it properly. Don't cant the bow for pictures.
PS I just took a little measure on your full draw picture and it looks like you've got the arrow nocked about 2-3" high.
-
The bottom limb is bending in one small area only, hence the set it took. You can see it at draw and unbraced. It needs to bend up into the fades a lot more. The top needs to bend a bit more towards the fade as well. Belly splinter/fractures/chrysalis don't just happen for no explainable reason. Splinters popping on a back, however, can sometimes be a mystery.
-
Welp ive been tillering.... and its getting worse... used thr gizmo on the bottom limb then took same amount off the whole upper limb... but the tip limb refuses to bend as much as bottom... dropped downto 50# and has taken another quirter inch of set... well darn..
-
It's all part of the learning curve!
Pearl is dead right.
Never, ever sand a chrysaled area as it WILL get worse. Again as Pearl said it chrysaled because it was bending too much and or had a stiff section just tipward. The extra bit of a ring just next to your chrysal is a sign of this.
Your thicker limb was likely deflexed somewhere along its length, thus making it look weak and you leaving it thick to make things even.
When you have a stave where the tips don't line up it is a very good idea to rough out the bow then use either dry heat or steam to make corrections and even out the limbs prior to starting tillering.
Hickory must be dry to avoid a lot of set and it also likes a good heat treating of the belly.
-
Yes indeee bownarra... i did match up the tips and make both limbs even when ruffed out both limbs reterned to there original state though after bending them for a while..
I heat treated the belly several times..
-
Alright well thanks for all of your good advice. Im going to call it done and tryan make another one with all the new knowledge! :BB

Some set aint the end of the world. Makes for a smooth shooter. Just as long as it does not continue to loose weight. Haev a HHB I made with wood that was not fully seasoned. Yes, it took some permanent set and they stayed 44lbs at 28". Lost early string tension but it is the smoothest killing hunk of wood I own. Think I even shot it for half of one IBO championship final round one year. It held its own very well.
