I have a DeWalt DW733 planer. I just changed the blades for the first time,
using the DeWalt magnetic alignment guides provided with the machine. I
can't figure out an easy way to use my indicator gauge to reliably check the
alignment of the blades directly on the machine so I planed two pieces of
wood at the ends of the planer (about 10" apart on center) and checked
thickness with my indicator gauge on my table saw table. Repeated a couple
of times and got a consistent 0.004" variance in depth of cut between the
two ends of the planer. No snipe on the boards. 0.004" seems like a lot of
variance over 12" on a planer. Do I have unrealistic expectations? Any
thoughts?
