Sorry, I don't agree with you. Practical experience tells me otherwise. Disagreeing is not bickering... it's just an opinion that differs from yours. I do try and base my opinions on experience.
Do something once, it might be good... do something 100 times and it'll likely be better.

sounds good.
just every time I try to glue up more than 2 layers for anything i botch the glue-up.

Why? How can I help?
Thesquirrelslinger:
i dunno. i have managed to make a 2-layer(RO and 'boo or cane, really dunno which cause 'cane is a species of boo)...
it delammed cause I left it outside on the woodpile in the sun and rain(glued with tb1)...
I have tried to pull off a trilam. it didn't work. then i tried to do a 2 layer tip overlay on a bow for a friend. it also failed(in a rather spectacular manner)...
i think its just me. I shall stick to selfbows and not have a problem.

If you can do a bi-laminate, you can do a tri-lam! The gluing process is no different. If you're using TB glues, your surfaces must be clean, flat and fit exactly. Eliminate 'gap filling' from your vocabulary! I use 2" wide lams, and stack them in whatever combo I'm wanting. Wrap with bicycle inner tubes, and you're good to go. The backing and core lams are usually 1/4" thick, and the belly is whatever thickness is needed to make weight.
Stop leaving laminated bows in direct sunlight!! >:( That's not the bow's fault, that's your fault!! If you treat your bows like firewood, that's exactly what they'll become. :o
Thesquirrelslinger:
yep- the overlay was kept in the basement.
The trilam was my 2nd bow.
and i treat my red oak longbow like firewood with no issues... it seems to like it ;)
