I want to know for those who cut and grind there own Core laminations of fiberglass limbs how thick to you cut them. I have been cutting them at .1000 and then grind them to my final thickness but it seems a little small. After cleaning them up I am real close to final thickness and a few times I have had to increase the center lam to get the correct stack.
I'm thinking of .1250, what do you do?

i think you are fine... you'll get a better quality limb with thinner lams. that extra glue line adds stability too.IMO

I currently run 3 bamboo cores and glass that equals 5 total in the stack and if I do veneers there are 7. Do you suggest I use a minimum number in my stack? Is 5 enough? If I go to 6 will it really be much difference? Should there be a minimum.

I cut mine on the bandsaw at about 1/8".  I eye ball it..

Then figure my overall stack.. say .255.  Then subtract the glass.. black - .030, so .060.  That leaves .195.. divide by 2 or 3..  .0975 or .065.  I would go with 3 .065's because they seem to bend and form better.

I find if I cut at about 1/8".. I have the flexability to do what I need to do.  Sometimes a little more grinding is needed, but that is the way it goes.
