Love the pen and also hate working with burl That is not stableized. As far as smell.. I mounted my DC to the wall next to the lathe. Put a 4"
hole in the wall with Flex dryer duct and dryer vent on the ouside wall. And then flexible aluminum 4" line so I can rest it next to or below the lathe to pull the dust, vapors, shavings etc right outside. No more dust. Chemicals. Smell. Now the backyard gets it.
