Been up sense 2:00 am working on this one just got it to brace Im 1/4 positive on one limb going to start hand tillering it tomorrow get every thing even then get it as narrow as I can get away with, Im guessing Im 58-60 lb now but the early weight on this one is much more then the last ,Im going to try to get this one as close to 1 1/4 width but doing it by hand with sanding sticks its going to take a while no string and play with this one...lol [attachment=1] PS the flavor of green glass sucks  :goldtooth:

The left limb looks normal. The right one looks to have a hump about mid limb??

Mike Here is a pic of the other 64 in. With the 64 in. I had to increase the brace to 8 1/2 to keep the string from slapping the limbs Im figuring if I lighten the limb on the current one it probably will take the same brace look ?[attachment=1]

I hope you are right. That one have the super lam? Almost like one side may have gotten reversed.

Yes it has the supper lam I don't think I reversed it I matched the end marks that Kenny put on ,the first 64 in. One limb was stiffer to but not as exstream the stiff limb is a tad wider not much though, I will clean every thing up tomorrow , I'm wondering to ,there is about 1/4 in. difference right out of the fades I will start fresh in the morning and see ! I'm going to mark out about every 6 in. Or so on the limbs tomorrow and make sure the front view profile is exactly the same !

I just put the calipers on the thickness out of the fades and at the knocks every thing is the same Mike !

Is it morning already Ritchie :laughing:

It does look a little wonky, but I'll bet you have a wide spot in a limb. Did that on the bow I built my son. Threw the braced bow all outa whack.

Thats good if everything measures good. Probably is a wide spot then.

Now it's morning Brad 3:00 am...lol I meant the 1/4 brace different but as soon as I get to the shop I will measure width, its changes might be a little more exstream with carbon don't know never used it before ? I'm just going to use sanding stick & brace it every pass see if I can get it around also need to lose another 1/8 in width when straitened out going for at least a tad under 1 3/8

Cleaned it up and it came around , this bow with carbon in the limbs is harder to tiller kinda sensitive to tiller but thats good should be able to get it to a weight I can handle its setting at 1/8 positive Im going to narrow it down and see where Im at but want to get it on the tree see where Im at weight first [attachment=1,msg2832219][attachment=2,msg2832219]

It does look a lot better. Did you reduce the stack for the carbon and still came out heavy?

Yea with the more reflex its more sensitive to ,weight it 63 lb at my draw could pull that in my 40s but not my 60s ...lol ,Im scribing the limbs with pencil and taking the width down by hand sanding if I can get it to 55-56 I could handle it well see ! I did reduce the stack & it did come out heavy by 10 lb this thing has scary to brace early draw weight much more then the glass cousin !

Ok here is a new one I took the limb width down by 1/8 in. didnt lose any weight and if you look in the pic it is more hollow in the middle similar to what the composite horn bowyers call poisin effect from not using a lenticular shaped core or the topless form is putting more presure in the middle like we discussed before any ideas ?? The limbs are at 1 3/8 out of the fades the braced profile is the same ?[attachment=1,msg2832249]

Im guessing my only solution is trapping but I have never done it on a glass bow it would kill 2 birds with one stone I need to lose weight any how ?

.030 metal one I'm ether going to have to go thicker or build a top for the form I'm thinking I can save this bow but not doing another as is , but I'm going to post a thread on trapping never did it on glass,  wood yes,maybe some body can talk me threw it !

The last bow I built came in heavy also.
I ended up trapping the glass on belly side and glass plus one taper on the back.

I used a file and was careful to keep it at a 45degree angle. Then I just filed to the desired glue line. Then finished with a couple quick passes with a small sanding block. Managed to drop 4-5lbs.

Thanks Brad Im going to scribe a line 1/16 each side in on the the back and trap from there and see how much weight I lose !

I apoligise for the crap pics & with the shop lights makes it look like the right limb bends more but it's not, I narrowed the limbs to 1 5/16 & double trapped the limbs really only a minor trap ,but did manage to get this to 60 lb at my draw I was surprised I got it to anchor but did , this is the hardest bow I have ever had to get to lose weight the cupping in the limbs is only minor now with it less width & hopping it adds some speed ,I'm 1/8 positive tiller with the left being the bottom the last pic is full draw @31 in. 60.2 lb I'm hopping I can lose another pound at final sand but stoping here it seems stable and the string tracts dead center & no twist ![attachment=1,msg2832468][attachment=2,msg2832468][attachment=3,msg2832468][attachment=4,msg2832468][attachment=5,msg2832468]
