Title: Newbie Question
Post by: DoubleLung on October 10, 2014, 11:21:00 AM

I'm ordering materials for my first layup and have a question regarding laminations. My stack height leaves me with the options of the following.

 doing glass, 2 thicker laminations, glass
or
doing glass, 3 slimmer laminations, glass

Is one a better option than the other?

Using the 3 thinner ones just allows easier bend to the form I think.
And would probably be more bullet proof because of the extra glue.

Thanks, I ordered the layout with 5 laminations (including glass).

Yeah agree, 'gut feeling' to me is more lams and glue lines 'seem' preferable.

yup, as mac says...it will handle the curves up the riser ramps better.
the kenny m bows use 4 wood lams and then two glass lams.
but check the fit thoroughly during the dry runs!
there is a way to work around the riser ramps- if you are not getting a good fit there- but cross that bridge when you get to it!

The curvy-er the form, the more lams you want as they will bend easier.  I made a bendy-handle flatbow with a single .125 pine lam core between two .40 glass.
