i have the same fence on my gray ridgid ts2412. holds it's settings and is rock solid once adjusted properly and locked down.That fence was offered on the Emerson saws at the tail end of their craftsman run. Most ridgids also came with it.
the 4512 is a nice saw, as long as a unit without the "blade/miter slot alignment changing with blade elevation issue" is located. and what is "an aftermarket drop in for use with a router" ?i would go with a new ridgid 4512. thats what i'm upgrading to when i get into my new house.
its $549 i think and has some great features like switching to 220, 36" wide extension, an aftermarket drop in for use with a router, great fence too.
the 2400 is a job site saw and it's fence system is different from the one of the linked c-man.It looks a lot like the fence on my Ridgid 2400 which is horrible! Maybe they've been redesigned, but mine is off nearly 3/16" from front to back consistently. It's the whole reason I'm looking for a new saw.
the less than optimal fence system on older c-man 113s is quite different from the one on the c-man KS linked. the fence on the linked c-man, although not a t square like a bies or a delta t2, is nonetheless a first rate and eminently usable fence.I had a Craftsman contractor saw from the 80's that had a crappy fence. I picked up a Vega for a couple of hundred, and it's been great.
That Powermatic should be a really good saw. Looks like a 66. If I were closer I would jump on it!
