Well, maybe not new, but...
When I bought my Delta contractors saw a few years back I fought with buying
the 30" or 50" rail, finally bought the 30" and have regretted it ever
since. I bought a 50" rail off EBay a while back and finally put it on my
saw the other day. I extended the right hand table to match the length of
the rail and tossed the 48" wide out feed table I build back then too. I
replaced the out feed table with a drop leaf table, but the whole width of
the saw and I'm loving it!
