I’m unfamiliar with Harbor Freight except by reputation as they don’t have a presence here in the UK as far as I know, though I was certainly tempted to get hold of a pressure vessel and pump when looking into the stabilization process myself. It does look pretty fun. In the end I found a bloke who does a nice little trade in vaping mods as well as stabilized blanks, selling mainly to knifemakers I believe.
Thinking of putting together your own setup?
