Gluing up African Mahogany
I bought some 8/4 African Mahogany to build a counter top for living room cabinets. I paid the place I bought it from to clean it up for me and make it glue up ready. When I got it home and laid it out, I was a bit disappointed with a few things... looked like it was ripped with a rough cut blade... lots of tiny tear out chunks on surface... visible blade marks and could feel them also... a couple boards had cracks angled toward the surface... a couple have bows in them that will take a lot of vertical pressure to get to line up with neighboring boards... and one board is very twisted to the point that it will be tough to get a good glue joint, and even then, the twist may be hard to sand out of the final counter top (at back edge). I am going to run it through a sheet sander when done and have about 1/4" to work with, so I am not so concerned about the surface imperfections. Luckily my neighbor has a floor standing jointer and we ran them all through which helped a lot... but the twisted piece is my biggest problem... I feel like buying FAS, glue up ready wood should not have these issues. Anyway, I will deal with the lumber yard on that... my main questions are:
1) After jointing the edges of African Mahogany, are they glue up ready or should I sand before glue up? if sand, what grit? And do anything to remove sanding dust?
2) If the wood sits for a few days between jointing and glue up, do the edges need something else done to them? ie do moisture, tannins, etc. cause any glue issue if it sits too long?
Thank you! First glue up!
