I have the detailed drawing of the freeze plug tool, somewhere. It's on my other computer, at home. I'll be there by this evening. It takes me a while to find it whenever I look, but I'd be happy to send it to anyone. OTOH, Knuckledragger's offer to lent his is hard to beat for a one time job.
I am always impressed by the generosity of the OB members. I recieved Knuckledragger's driver and it is in perfect shape.
I'd love a copy of the drawings should you come across them.
