Just a quick question on your wood. were you using birch hardwood or just birch plywood. I have tried birch plywood from lowes and found i get a lot of what i call chip outs. where sections on the bottom chip. I think this is caused from the way the grain runs. when cutting smal detailed things, theres not enough to keep he wood from breaking from the pressure of the blade on the cheaper type of plywood. That being said, I do use spirals exclusivly as i find them easier to use. A lot of people dont like them because they can wonder as the will cut in all directions. But if you go slow you can control that somwehat. It is very hard to get fine detailing with a spiral due to that fact that they cut all directions and will have a wider kerf than a standard straight blade. They are also harder to get 90 degree cuts with, but this can be accomplished with some practice. take a piece of test wood. cut a straight line with it. mark a stopping point on a line and stop when you get to it. you will find that the blade will cut a little farther than the stopping point due to the blade flexing from pressure as it cuts. with practice you can learn the blades stopping point, stop just shy of it and let the blade catch up, then turn the corner and you will have a good 90 degree cut. Spirals do have a learning curve, but with practice you can use them. I hope this helps you. Also note this is just my personal experience, as I have only been scrolling a little over a year. For me the spirals were a lot easier than standard blades, But again this is just my personal preference.. It really is up to each individual as what will work best for them and their machine. Just relax and have fun because thats what this hobby is all about.
