Hi, I am trying to make a 45 miter with my radial arm saw. I have
'tuned' the saw as best as my sanity will allow, using 2 RAS books and going through all steps multiple times.
The blade is a brand new Chopmaster 10" with stiffener. I made a miter jig that I clamp on. The problem I am having is that it seems to be cutting more away upon entry of the piece (I'm talking hair widths, but enough that matters in a picture frame).
On a 3/4 x 3" of oak, the cut is perfectly smooth but when I hold my straightedge to it, it is straight cut except for the entry area (perhaps an inch length fades from square and I can see slight semi circular saw marks in that first 1" or so when looking at the cut). I have tried clamping the workpiece, I have tried sawing in reverse and when I did that it seemed to have the effect but from the opposite side. I even tried using a backing workpiece thinking maybe the saw was deflecting. This offset my workpiece 3" of course and allowed it to enter the workpiece already under work, and somehow it still had the same effect (so I don't think it's a deflection from the RAS arm or motor housing). I don't understand. :confused:
