Got this trilam finished. Hickory, Purpleheart and Ipe. 65 ntn, 19 inch Merbau powerlam, riser built up with strips of Merbau and Maple. All three full lenght lams were tapered before glue up, came out without having to do much adjusting.

Bue

Post by: Buemaker on March 03, 2023, 02:15:08 PM

Max. Total taper 7,5. Hickory backing .0015, Purpleheart center .003 and Ipe belly .003. Next one I will make a reverse taper on one of the  lams the last 6 or 7 inches to stiffen the tips a bit.

I've done it at .006 just to help it bend but still had to scrape a good bit to get it tillered.
