Title: 'nother lam ??
Post by: kennym on June 18, 2007, 09:38:00 PM
How many lams are necessary in say, a 55# 64" hybrid longbow?
 Just built a couple research bows with 2 wood lams w/2 glass like a recurve,was wondering about the durability compared to the usual 4 lams w/ 2 glass?

Or should I expect em to blow up in my face?!?  :scared:

I don't think they will blow up in your face just not as consistent as a four lam bow.

How did you get the thick lam to conform to the fadeout?  Chad

2 lams is what i do usually.
but my belly lam run sraight through the riser,though they dont have to "climp up" the fadeout.
no failure so far.

Both.  I'm just thinking if you have one lam that is inconsistant (maybe a knot, soft spot, etc.)then 50% of your lams are inconsistent in a 2 lam bow.  If I was only going to do a 2 lam bow then I would use action wood or action boo(flooring) because by the nature of them they are consistant.  

For a 64" 55# longbow your 2 lams would have to be pretty thick.  For my hybrid bows that would be about .150 each with one being a taper.

A 4 ply piece of plywood would be stronger and more consistent than a 2 ply piece.  Although I know bows and plywood are not the same thing.  Chad
