I've been using cauls for years. I'm looking for something a bit easier to use. Making fancy end grain cutting boards for friends has created a new need for something better than what I've been doing. I was also thinking about using some 1X square tubing, then I stumbled onto this Panel Max system and it looks like a decent system. End user thoughts would be appreciated. I'm also curious if it has to be used vertically, or can it be used off a table?
