I picked up several Mango planks while in Hawaii on vacation a few months ago, and I'm attempting to make some picture frames for some of our vacation photos. Mango is a very pretty wood, with pronounced figure and streaks of pink throughout the wood, but I'm having a devil of a time getting good glue joints. I'm attempting to glue end-grain to end-grain at mitered corners, then place a contrasting spline across the face of the joint for strength and appearance. The trouble is that the mitered corners don't seem to hold together long enough to let me cut the kerf and glue in a spline. I've tried Titebond II with poor results - possibly due to the shop being unheated and around 50 - 60 degrees, but I haven't had that issue with other glue-ups. I've also tried epoxy with slightly better results but still experiencing failure as soon as I attempt to sand the joint smooth prior to cutting the spline kerf.
Anyone out there worked with Mango and had similar problems? or better yet, discovered a solution? I suppose I could go to a different type of joint with more face grain glueing surface, but now it's become a personal challenge that I want to overcome.
