I took a step forward today, having decided to try out the variety of blades I already had. I wanted to see how each blade performed, so selecting each and making a cut into 1/4" ply seemed a good idea.
This way I can feel how each blade feels when cutting, see the actual width of the cut and be able to see the underside to check any breakout.
The Flying Dutchman Superior Puzzel with 31 tpi was exceedingly smooth and easy, with very little breakout.but I dont know how I would get on with such a fine blade on thicker or harder wood - probably break a few. At the other end of the scale was the FD #12 with 10tpi, which I recon would go through anything, but with a very wide kerf and more breakout.
Pegasus #3 blades 90.440 reverse shows some front breakout but less on the back, which seems odd and perhaps its the ply to blame? The P #3 90.440 18tpi was a clean kerf and very little breakout. Pegasus #5 90.429 15tpi skip blade was very nice, smooth slender kerf and vertually no breakout and the FD #5 ultra reverse 15tpi looked slightly thicker kerf than the Pegasus but was beautifully smooth and easy. Pegasus #7 90.408 gave a clean look but a bit rough on the base.
I hope this may help others. It's also useful to me to have that ply next to the saw for future reference, along with my array of files of blades and various sawdusts for glue mixing (sorry about the quality of the crop).
