Okay, so I couldn’t leave it alone. Sue me.

It all started when I brought down to the dungeon the multi-purpose base I originally made for the router table, then added mounts to for the Delta 36-510 table saw I bought used earlier this year. I decided with a little bit of room to move around down there I would once again see if the arbor bearing was really as bad I as had thought before. For testing I mounted a spare Skilsaw 10” 28T combination blade. I made no adjustments to the vertical blade angle or the alignment of the blade to the miter slots from the last time I used it. I grabbed a small 4” wide pallet slat that had a decent straight edge to make my first cut.

As before, I saw a lot of burning in the cuts I made. I wondered if I was feeding too slow and the board was bouncing into and off the fence as I was feeding. Speeding up the feed rate got rid of that problem, however another problem surfaced, now that the cut was clean. The blade was sniping the last 1/4” of the board as it exited from between it and the fence. A few attempts with more pressure from the oversized thin push block didn’t help. I decided to cleanup and mount the riving knife/blade guard assembly. The riving knife might be able to keep the the inside board from running into the rear of the blade. And it worked. Here is what the saw now looks like with the combination riving knife and blade guard assembly mounted.

I set the miter jig to 90 degrees and trimmed off the bad edges, now that I have two parallel cut edges. The ends came out dead on after several tweaks of the miter angel using a small square. Here is what the board looked like after all cuts were made.

Here is a cross-cut end.

The closer edge of the rip cut.

And the rear most edge of the rip.

It’s unfortunate that my camera (and skill level) can’t show what my eyes can see. For what can be seen in these photos, do you think the cut quality is accurate enough for non-cabinetry type construction? I’m speaking of better than contractor quality work, but not where the tolerances are measured in thousands.
