Finished two bowls so far. It is a hard wood, but no harder than the
local elm. My biggest complaint is the porosity. After finishing the top
and sides I reverse chuck using a vacuum chuck. Even with the finish on,
they will barely stay on the chuck--you can hear the air sucking right
through the bottom.

I pre-finished one with precatalyzed tung oil. It seemed thoroughly dry,
so I steel wooled it and put on the finish. The vacuum pulled un-dried
tung oil from the pores through the finish. What a mess.

Looking forward to some photos. Interesting about the vacuum chuck.
How many psi are you pulling? What finish are you using over the tung oil?
