Title: Trilam De-lam at tip
Post by: cool_98_555 on June 16, 2017, 05:39:58 pm

Hi everyone,

I'm working on a trilam right now and I had it all the way to a 3-4" brace, tillering nicely.  However, just recently, the bow delaminated about 5 inches from one of the tips between the backing and the core lam.  I've had this happen before with a different bow and I just opened it up and poured super glue and then clamped it overnight and it seemed to hold.  The delam was super clean, no signs of middle lam on the backing or vice versa.  Do I continue with superglue? Will it hold?

Thanks

If it is a non bending section superglue might just hold it together, I had the same on one tip of a molly and it still shoots today. Filled it with superglue and wrapped with some serving material. If it is on a bending section superglue is probably too brittle and will break after a while. But if you had a delam before there can be more problems, did you degrease enough? Did you use epoxy and used too much clamping pressure? Might sort that out for your next lam bow.
Cheers,
