Hydronic press. I use a Bonny Doom for metalsmiths. Well, I have used it, but it's just not worth it unless you can get hold of whole leaf tobacco, IMO. Otherwise, your just making a crumble cake. Pressing it melds the flavors and slows the burn rate. But, with crumble cake the burn rate isn't a big deal, because the combustion breaks apart the cake bits as you smoke it.
