I think this is getting close to brace height but would like to check with the experts. Thanks
-
i would say go ahead and brace it
-
I'd brace it up, but you look a little stiff mid limb and out on the right limb to me

Get right center moving a hair and It's all about weight reduction from here...Looks nice 8)

Thanks guys. I will shave some off and get it braced...now for the hard part this were I generally break em'. I do believe that im not exercising the limbs enough and thats when they go boom. Im taking my time with this one. Its going to be plane jane but hopefully I wont break it. I got discouraged after the last onr broke and quit for the summer. Now I have a shop and can work all season long. Thanks again for the advice. I will post pics as I go along.

Id suggest a short brace now prior to wood removal anywhere, when you start pulling the tips not only down, but in, it changes how they behave. Im a HUGE proponent of an early brace.
-
Its at a low brace about 3 1/2" and pulling 30# at 20". I think I need to take a bit mre off the right.
-
I agree with taking a smidge more off the right. It also looks to me like the LH inner limb just outside the fade is not working quite as much as the right??
-
Your turn that picture upright and hand draw it and I bet it looks pretty dang close.
-
It looks good but the thickness appears to be the same in the fades.
-
If anything i'd get midlimb to tips moving a tad more, looks nice though
-
Hope I m note being redundant here but its pulling to 25" and about 35#. Its 64" t2t and im going for 28" is that possible.
-
PD is right - time to hand draw it and evaluate from there. Looks like great work so far!
-
Here the full draw is its taking 3" of set. Will toasting the belly help that? What do you guys think? This will be my 4th bow that's made it...if the set doesn't ruin it.
-
your fd looks good! As far as set goes, is your wood good and dry before you begin tillering? Also how do you go about tillering? I get mine braced as soon as possible and I exercise it twenty times after each time I remove wood. I also never draw the bow past my intended draw weight. This method combined with dry wood will lead to low set. It looks like maybe you were pulling it a bit far before bracing the bow
-
The wood was dry and I've only drew it to 28" a couple of times. And I exercised the the limbs about 20 times after scrapping. I must have pulled it to far to soon. I haven't checked it for a couple hours so it may have settled down a bit. Will that kinda set kill the bow?
-
More towards the tips if you ask me.
-
You should look on the belly and see if you see any chrysals
-
Great job for your 4th bow, make sure of your finger location (arrow nocking point ) when pulling and taking pics when doing the final tiller. an inch or two one way or the other will make a big difference.

+1 on both. Looks great for your fourth bow.
Your handle looks pretty thick still to me. That can help with the draw length just a tad.
62ntn ain't bad for 28" it's a little close. That may be where your getting some of your set. I am finishing up one now that is 57ntn with a stiff handle pulling it to 27" but it's Osage.
Looks good, Patrick.
-
Same what Patrick said.
Don't want to hitchhike that thread, but what is the motivation th back hickory with hickory? Is the main lam a board with grain running off, or what? I'm no expert on hick.
-
It's always best to stand parallel to a wall and try to get the best right angle shot(trying not to cant)that you can.as noted, I find it best to use an arrow when doing a f/d pic because I find it easier to have every thing square up naturally.i like to monitor the set from the get go,constantly unbracing and sighting down the limbs to note the deformation and using it as a guide in my tillering strategy. Also try to keep the set mostly in the Midlimbs because set closer to the fades will equal loads at the tips
-

How is your tiller tree set up? I can't tell from the photo. Was the bow drawn with a pulley arrangement from underneath for the photo or did you hook the bowstring on a notch or a screw? What I am getting at in my round about way is how long you kept the bow drawn to 25". Holding one that far drawn for too long a time can induce some set, and especially before all your tillering imperfections have been worked out. I don't leave one drawn for more than a few seconds anywhere past twenty inches of draw. My observations on tiller past twenty inches are made through photos, mirrors, shadows on the wall, or having someone else draw it while I watch. Final tiller for me has to be achieved based on how the bow works in hand. Hope that helps. All of my babbling aside, good work on your bow.

your right im going to take some more from mid limb to tips today.

I see no chrysals yet. The last hickory I made was a Molly and it chrysaled in the top limb but stills shoots. Lost about 5# of weight though.

I have my tillering tree nailed to a stud with green board behind it for contrast...(it was hard to see the bow in pics). I have everything that I need to for a pulley system except for the cable. As soon as I get that I will set it up correctly. I have notches every 1"starting at 7" up to 32". And I think your right I keep it pulled to long. I dint even think about that. I will remember that on my next one.
-
Looks great for your 4th. I have made a couple or three hundred bows by now I guess and I still manage to screw one up from time to time - you never stop learning in this bow building stuff! :) I can tell that you are bit by the bowyering bug. There will be lots of fine bows in your future. I think that you have learned a lot on this build.

To my eye the right inner limb in the first picture was bending too much and the tips not quite enough on both limbs. As you progressed you didn't correct these problems and the full draw picture shows the same thing. Ideally you should have corrected it before bracing it.
One thing I keep a really close eye on is how the bow takes set as it gets bent further. Set is the wood showing you that it's working hard. A bow will always take some set - it's unavoidable but you can limit it by distributing it along the full limb - aiming for very little inner limb a bit mid limb and the most mid to outer limb. So if one area alone takes set after exercising it is weak. An area that shows no set is stiff. The wood will tell you what to do......if you know how to listen ;)
-
it might be a moisture content thing making the set,, your tiller is pretty good,,,maybe the limbs could bend a little more evenly mid limb out,, but really hard to tell in a photo,,
-
I see really stiff tips. Bend those suckers ;)
-
I've taken a little off mid limb to tips. Going to do some more tomorrow. I think its going to end up a little light but if it shoots an arrow ill be happy with it no matter what. I'll post pics of the finished bow.
