Strip: Notes on 7.25 inch saw blade

Not planning to "engage" but wanted to give something back to the group.

Based on some recommendations from sources I can no longer recall, I decided to try cutting strips with a 7 1/4" blade on my table saw. It seemed to be working well, but I noticed that after 8 or 10 strips the edge of the board was going noticeably off-parallel. I'd flip the board over and start again on the other side, but ultimately ended up with a wedge-shaped bit of wood about 1.5 - 2" wide at the base. Initially I thought it was bad technique on my part, or that I was starting with boards that weren't true in the first place - and both of those may be the case as well.

However, what I think is going on is that the kerf of the blade is very slightly narrower than the width of my riving knife. Therefore, on the first cut, the riving knife prevents the board from sitting flush against the rip fence, and creates a very slight taper in that first strip. I believe the subsequent strips have a consistent width - I hope so, anyway, as it took a few boards before I realized what was going on (I'm using 6' boards - planning to scarf the strips later).

Anyway, as any advantage from the thin kerf is outweighed by the additional waste, I went out and bought a 10" ripping blade. The only one Home Depot had is still a thin kerf, but it appears to be within spec for my riving knife. Haven't been able to try it yet but hoping for the best.
