If memory serves me right, someone ws saying that they are having trouble cutting straight lines - (I think that is all of us). I think this also goes with cutting large (i.e. >6" diameter) arcs.
A couple of things I can think that I do is:
Line my chair/stool up with the kerf - my blades tend to cut more on the right side, therefore, I line my chair/stool up to the right of center - in line with a "straight" cut kerf
I don't change the position of my hands during the cut thereby "eliminating" changing dominance of one hand over the other
I try to apply steady pressure during the cut - changing the pressure will cause blade characteristics to change the pull angle
I don't rush - tends to enable minute changes in direction without causing a perceived crooked line
There's my thoughts - how about your tips for cutting straight(er) lines? Appreciate any input guys.
