Reverse Spiral Blades?

[ozarkhillbilly]

I ordered some FD 2/0 reverse spiral blades and recieved them today, I ordered them in the hopes of reducing the amount of fuzzies I have on the backs of my portraits. So out to the saw I went and started making some sawdust. I stacked four 1/8 pieces of bb plywood and was impressed with how the blade handled. But upon finishing the portrait and examining the pieces I found that while the amount of fuzzies was reduced I had fuzzies on both sides of the bottom 3 boards not just the bottom side. Now normally I burn my fuzzies off the back, but can't even think about putting the torch to the front!! So I found myself having to very carefully sand the front side of each portrait No mishaps, but a lot of extra time spent.
Is this normal results from reverse spirals? If so, its back to the old tried and true spirals for me.

I've had the same exact problem...... Solved most of it by using nails to really tighten up the stack.
