The way my drill press is setup, the rear has a natural tendency to dog track. What this means is when I drill a car with the way the drill press is set, the rear is perfectly centered between the rail with the bend in the DFW axle. With these last few cars, I have no need to narrow the DFW side. As long as I used a rigid fence durnig the drill (using the SB), I do not forsee any problems with it this way and it seems like less work. Is there anything wrong with this approach or is this a bad practice?
