Does anyone know for sure if oak cubes always float? I do not want to have to back them and I don’t want them clogging up the bottom of my conical. Seems like they float IIRC.
They usually float for a while, but if you let them sit too long then they will eventually take on enough liquid and sink. I don’t pay enough attention to know how long that takes though, sorry. More than a couple of days, less than a couple of months :-\
Hmmm … perhaps I will rig up tiny flotation devices. 
Thanks. I guess I’ll bag 'em.
little tiny teeny life vests… how cute ;D
yep, if you want them to float, bag them with a ping pong ball.
Love the ping pong ball idea, thanks!
Thats an excellent idea. Added to my bag of tricks
Now that’s brilliant!
