I have stopped to making nothing but acrylics lately. THey seem to sell fast and are easy to finish. I just can't seem to get a decent finish (one that I will accept) on a piece of wood. I have hundreds of wood blanks accumulated just waiting for a kit, but every time I try one they just don't finish out well. I haven't given up, just concentrating on what I seem to be able to do well and leaving the hard part for when I am better at it. I still do a few wood pens a week, but they are accumulating with unacceptable finishes and rising overhead cost with no return. Looks like I will drown in the acrylic lagoon until I can get my CA to be OK.

Try rounding over some common woods -- like walnut, cherry, maple. You can do this between centers and there's no need to drill a hole. Sand them to 600 or so, and practice your CA finish. That way, you don't waste any tubes or pen kits, and you can practice all you want at very little cost. Experiment with different variables -- thin/medium CA, with and without BLO, with/without accelerant, different lathe speeds, etc. I have done that on a great many blanks trying to work through the same problem that you described.
I've come close to giving up wood blanks for the same reason. But acrylics, to me, just don't have the uniqueness and the versatility that you get with wood.
