I have seen on several sites listings for bandsaw fence systems with rails that are mounted parallel to the edge of the table. Several of them appear to be compatible with my saw which has no fence. My saw is a 14" import with parts that interchange with those of some Deltas, Jets and other imports. I would like to equip my saw with something similar, but would have to drill the edge of the table to accommodate the rail mounting bolts. What I would like to know from anyone out there who has a similar fence on their 14" saw is the distance (center to center) between the mounting bolts and whether or not the holes are tapped for threads or are smooth to take a bolt/nut. My table, although not drilled, has the casting nibs under the table edge where I could drill.......Thanks, Butch.
