So when using a spiral, are you pushing sideways on the cuts or do you just spin the work with the saw off so you are always pushing forward? I bought my saw used YEARS ago, and the guy I got it from has sooo many spirals, and I just never touched them. I mainly cut Cherry, Ash, Oak, Maple, I really don't do plywood, and I cut mainly 1/4" using Olson #2/0 R blades.
