I made a riving knife for my old Delta Hybrid table saw. That work required removing the trunnion. Now I have to re-mount it and align to the miter slots of the table.
The trunnion mounts with four 1/2" bolts to the underside of the cast iron table, but the bolt holes are about 1/4" oversize to enable room for adjustment to align with the miter slots. I have no sleds that would have to be considered, and Ill have to install new zero clearance throat inserts anyway, so I thought that I might just slide the loosely-mounted trunnion front-to-back and side-to-side in order to approximately center the bolts in their oversized holes. Then I would snug down one bolt as a pivot around which to rotate the trunnion until my dial gauge shows it properly aligned, then tighten all of them.
Anyone have a better way to suggest?
