Thanks, toomany, that is what I thought--thinner wood bends easier for a reason.

Hey forest, would those be what you would call Nels Grumley style static recurves? I don't see recurves like that often at all, so I am not really sure, but the ones I have seen like that, other than yours, were called nels grumley recurves?

Them look like brush nocks to me! And mighty fine ones at that!! Nicely done forest! You should do a build along sometime and share your secrets with the rest of us.  >:D  ;)

Like toomanyknots, I reduce the thickness of my tips before recurving.  Actually, I TAPER them, heat 'em with heat gun, and bend them in a jig. Then, I apply thin laminations, increasing the curvature just a touch over the original heat bend.  By tapering the tips, I get more of a bend with less work and less stress on the wood.  The only problem is, you gotta put wood back (i.e., laminations).  I think you can see what I mean in the pictures.

And yep...those are brush nocks, made popular in large part by Nels Grumley.  They're not exactly like his signature (such as Bear Archery's Deerslayer model) but are certainly influenced by his and other bowyers' of the time.  And they really do work...that is, they keep brush from getting stuck between the string and bow.

"And whatever you do, whether in word or deed, do it all in the name of the Lord Jesus Christ, giving thanks to God the Father through him."  Col. 3:17

Diddo what TMK said about rounding your corners before bending.Using dry heat [after a few days]on your recurves to temper them does help to maintain your recurve too.

well i got my heat gun back tonight of a friend so decided to put the recurve back in. i clamped the bow in and heated and slowly started to bend when it was red hot while keeping the heat on it, and it cracked proper,  >:( its gone down one ring deep. so i thought i would file the rough part down and fill with wood glue. and i had some edge grain ash about 1.5 mm thick which was an off cut from another board (i new it would come in handy one day :)) i cut strips of this out and am goin to laminate with probably 3 layers and see how it looks, and then will probably wrap the area afterwards. what do you all think should it work??

Rasp it all away smooth and flat first, then add your underlays and skip the wrapping.

would it make any difference strength wise as i have already put the overlays on now and am just waiting for them to dry. i dont mind wrapping as this bow is being backed and i would use the wrapping to keep the backing down too. thanks danny.

I cant answer that. I believe it to be stronger replaced with solid lam's of wood. But hey, keep going and we will all know more about repairing tension cracks on statics.

well the other recurve split more than the first i dont know whether the wood gets to dry while heating or if its just to thick to bend. i had to cut away this one and smooth it out and put  in inlays  then build up 3 more layers. they tips now seem very strong  and i think they will hold together fingers crossed. i will probably wrap over the joints just to hide them as they look abit tatty.  i have abit more shaping to do yet and  will reduce them a touch so they aren't as bulky. heres some pics.
