I am new to posting so hope I give all the info that you need.
I have an antique horse drwn doctors buggy that was recently dropped and cracked three of the seat and driver supporting slats. they are cracked to look similar to a finger joint with jagged points. There are about a dozen total the are evenly spaced and run from the front to the back and support the seat and I guess it would be said are the flooring. The aren't exact but are roughly 1 to 1 1/2 inches wide by 2 inches tall. I want to keep this as original as possible but still stable. I want to repair like a finger joint and was considering either titebond hide glue, polyurethane, or just found structural epoxy. Any advice to which would be better would be great. Three of the slats only are cracked not all.
