I have tried spirals a couple of times over the last few years, never could get the hang of them. I decided to try again. I used a FD brand, can't remember the size. Now I know what everyone is talking about when talking about the fuzzies! I didn't have many, a little sanding knocked most of them off of the backside. I have also been wanting to do a Tiger or Leopard or some kind of big cat with spots/stripes. But I try to stay clear of patterns with an obscene amount of holes to drill! This one only had about 90 interior holes to drill,, so wasn't too bad.
I feel that I did ok with the spiral but I also feel that I didn't have to be perfect while cutting this pattern. I take pride in being dead on the line with my regular blades. I imagine cuts with more straight lines would be more difficult with spirals. I don't know if I will attempt anything like that.
The top part is 1/2" BB and the backer is 1/8" BB cut with an Olson #2 reverse blade. Remember, go easy on the reviews this is my first spiral cut! LOL
