One more time ! Glass thickness !

[Forwardhandle]

Im calculating my stack thickness using .030 Gordons glass & I have heard different theory's using the .030 vs .040 etc ,so Im adding about .010 over the same stack thickness if I was using .040 glass to companstate for the more limber limbs ,for you guys that used .030 glass in a stack does that sound right ?

gonna be really close.

Ok thanks Mike , Kenny thought the same thing , Im trying to use up left over material , and mixing and matching to get a bow !

I am experimenting with my first recurve TD limbs for a 60" bow and my first set came out too heavy to even string. I used 0.04 glass with a total stack of around .240 (I think).  Generically, to safely get a limb between say 45 and 30# would you use 0.03 glass?  I just want to be able to string and test it!    Any rough stack ideas, thinking parallel lams as a start.

You might want to ask Kennym he is pretty darn close on stack guessing, I have used .030 back glass with .040 belly glass on a couple sub 50lb bows with no issues !

With identical stacks using .030" on the back .040" on the belly.  Same stack with .040 back and belly gain about seven pounds.  Hope that made sense.

I say .030 is what you need ! I made plenty T/D's with .030 glass !
for the stack? .200 to .240-----------.225 will be exactly 40# give or take 10# ---

BJansen Stack Calculator said
For a stack of .240= 60# let's say
For a 40# bow the stack would be .210
Hope it gets you there

Don't see what the weight of this one was but usually I think recurved run .001to .0015 per lb

Ya kinda need to get the weight on that one figured out...

Send it to Roy and have him string it for ya!!

Thanks guys. I need to pick a stack and go for it. The set I built scares the crap out of me when I try to string it!  Longbows are safer
