Yep, tons of feature that need work. I have a difficult enough time with veneer let alone C++. The features are not up to me to build in but they are being worked on.

No experience with an oily wood in a hot area. I don't imagine it will be a fire hazard and after you finish the wood it will be pretty much sealed. The natural oils of the wood will eventually dry out, but this shouldn't present too much trouble. As with all natural things anything can happens. The wood could last an eternity just as it is, or the ends could dry out and check. The long time tradition to help the wood to last an eternity is to use a finish that will seal it from the environment. That's why better furniture has at least a few sealer cotes of finish on the inside that will never be seen.

A router wont be a problem. A vari speed router set to a slower setting might be helpful. If the wood is really hard and or knarly. you have to make a few passes to get your cut. If you make a pass or two with a router, I would leave yourself a very small amount that you can make one last pass, as a kiss pass. This lets you glide the piece through the router, (or the router through the piece) with very little force yet maintain even pressure and speed of feed.

Some of the exotics have some very nasty dust when worked and a mask is important. Some people are allergic to exotic woods. Coco bola can be one of them. Never heard of a problem with ebony. well, other than if your blade is not sharp your going to be in prime competition for a smoke show and starting a fire with out a match, along with the
