As some of you know, I purchased several box lots of tools from an estate. I'm starting to sort thru the final box and found a Jessum Pocket Mortise Mill II, P/N 08200. What can you tell me about it? I currently use a Rockler Beadlock for loose tenon work. Is this comparable? Better? Worse? I'm just wondering if it is something I should consider keeping. Would it replace the Beadlock or complement it? TIA
