Here is the closest thing to what you guys are doing that i've ever done. This is a toy box i built for my grandson about a year ago.

Yep
That's why this forum is so good, people sharing a lot of different ways to do things.
I would not go any tighter than 2-1/2" radius on the back of the bow.

Like kennys new form, been there, done that, don't try

[Kirkll]

I have a buddy that used to build a lot of high end bows that many of you guys probably know already. Steve Tallant,  Eagle Wing Bows.   
http://www.eaglewingarchery.itgo.com/custom3.html

He has a design called the “Talon” that has a pretty tight little curl on limb tips. Hence the name The Talon…. I remember back when he was first prototyping this limb, he had a tough time bending .040 glass that tight without his tip wedge sliding around. I believe he pinned it with something in the end game.

I believe he used to post on TG years ago…… but….I kind of lost touch with Steve. He is a gifted craftsman and bowyer of many years.  We were pretty tight years ago.         Kirk

Progress Mr. Km please

[kennym]

Purty slow on it, I'll take pic today.  I think it be better this way.  Will 3/8" steel pegs hold it?

I would think so

[kennym]

The guy will be responsible for checking waroage to see if angle iron needed. I’m gonna tell him to just go ahead and put them in it. Also for the steel dowel pins . I think topless is the way to go on this wild thing .

[Kirkll]

That is quite a job you did there Kenny. 

 Did you seal that real well with shellac or some kind of sealer?   How many layers of plywood, and what grade did you use?

That one should be fairly easy to check for twist with a straight edge diagonally. I sincerely hope she stays stable

[kennym]

I've checked and checked, so far all good.  Its going to CA so not adding angle and metal dowels here. Gonna wrap it in plastic and padding and cardboard and send it. He will have to seal it and add any angles it needs. Gonna tell him to just go ahead and put angles on it before he builds with it and heats it...

[Mad Max]

Nice kenny

[onetone]

Looks good. I second the need for sealer and steel angle and I hope we get some feedback on how the bow works out!

[Kirkll]

I’ll bet shipping on that baby is going to be expensive. I’m surprised he doesn't want it sealed prior to shipping….

Did you use cabinet grade plywood? 7 lam perhaps?    Kirk

[kennym]

Plywood was the best fir ply they had without going to oak or birch cabinet stuff. I prob shoulda priced it tho, as much as this cost!!

If you can find decent looking A/CX. the stuff is typically pretty decent if you get solid core.
The problems with a lot of the cheaper plywood, and even expensive stuff is the blows in the laminations from knot holes falling out. The old days of clear vertical grain plywood are over. Often times going to a marine grade plywood for forms isn't a bad idea.....

I gave up on plywood myself and stick with LVL material now.

[Longcruise]

I'm wanting to get to using the LVL but I don't have a local source.

I used chipboard T&G once on two forms.  One was stored in a shed for a couple years and swelled.  It did stay straight though.  Nice thing about it is that the stuff i had was true dimensions.  No fiddling with spacer stock.

[Crooked Stic]

That is a pro looking job there Kenny. He gonna need carbon to keep that from going sideways.

[kennym]

Yeah, he says he has carbon and trying to get S glass. Not sure where you can find that?

Thanks!

[Crooked Stic]

I think most of those super curve guys use 6 ply front and two ply belly no glass the 6 ply having uni and the two ply twill only..Rosewood has it but it ain't cheap.

[OldRawhide42]

Dave Barnsdale uses S glass in his limbs.  I do not know where he gets it.

[Crooked Stic]

I am thinking uniweft is about the same thing woven glass.
