Zero Clearance Inserts for SC table saw

I have to thank Alonso for getting me in gear to make inserts for my table saw. It is a Steel City model ?. Seems to be the same insert as the Rigid and all the SC line. I have an older craftsman too and I’ve found this insert is easier to make. Basically, it’s a rectangle with rounded corners. I used some scrap QSWO and carefully planed it to just a little thinner than the original with the leveling feet at their final position. I traced two blanks out of the scrap and ripped to the exact original width, cut to length and rounded the corners on the band-saw. The first one, and only at this time, dropped right into place. Had to sand one corner down then level. I used four small brass screws left over from a piano hinge for levelers. Gauged the depth of the rear hold downs then added some slightly larger brass screws, pic 3.
The hardest part was making room for the riving knife. The blade does not drop low enough to clamp the blank down into the slot so I had to VERY carefully catch the blank in the front with a push stick, start the blade, shut it off and let the momentum cut into the blank until it was safely seated in the saw-top cutout. I then clamped the blank with the rip fence and completed the cut. NOW, I realized I still needed more room to bring the riving knife through when I put it back on. I don’t want to cut through the back and lose the rigidity so I flipped it end for end and brought the blade up to full height again. This cut just enough to bring the riving knife through but too tight for safe operation. I pulled it out and used a piece of belt sander belt and a thin file to open the slot. Works great now, won’t have this problem for the dado cutouts.
Pic 5 is the leveling feet. The screws were predrilled and a small countersink added prior to attempting to screw in the soft brass screws.
Final cost was $0. Everything was scrap or left over screws. I skipped the pattern bit out of fear of hitting the steel insert.
Hope this helps someone save some money and have a usefull accessory. I welcome comments and criticism.
