I've been saving a piece of purpleheart for a special project. I only got it because Doorlink's favorite color is purple, and I wanted to make something for her (usually, the most expensive wood I ever get is maple). Anyway, she recently got a poster she adores, and so I've decided to use the purpleheart to make a frame for it.
So this evening I got home from work, and set about cutting and jointing and planing. So far, so good. I got the four nice pieces I needed. Only one problem... they went from a nice deep purple to a rich brown. I'd been told to expect this, but it was still a shock. I've also been told to wait a while, and it'll turn purple again.
So here's my question: how long will I have to wait? I've still got to run the pieces across the router table, and I figure I'll get that done in the morning. But then what do I do? Assemble and glue up the frame? Should I wait until it turns purple again before I put on a finish? What kind of finish should I use? (I usually just mix up 1/3 poly, 1/3 naptha, and 1/3 BLO, but that seems a cheap way out for such expensive material). And, more importantly:
How long before it turns purple again???
