Zero clearance insert

[Gadois]

Attached are pics of a zero clearance insert I fabricated from .25" aluminum and .020" steel sheet. The insert is epoxied to the steel and drilled to accommodate a blade up to a 9. The fixture attaches to the table of the saw (Excalibur 16") from underneath and will be held in place by magnets. The insert seems to be proud of the table top but is actually flush. The hole may have to have a slot cut in the back side to allow for fore-and-aft blade movement. Any ideas for improvement are welcome.

Cheers,
Gadois

You may want to open the hole up more than just front to back. Sometimes I make very small pieces with inlaid letters, so I also need the zero clearance, but the table is set to a 3-4 degree side angle. If you plan to tilt your table, you need more room on the sides as well.
