Need help Tiling

Hi All,

I’m cutting some dog holes in to 4 new workbench tops. The tops are 750 x 1220mm 18mm thick.

I have my 1m x 1m x carve in a enclosure with doors opening at the front. So i can cut about 2 x 3rds of the holes before needing to move the workpiece.

I thought i would put a fence on the Y axis, I thought i would set a small drill action to use as a reference point to rehome the match however I’m going to have to rotate the work to fit it back in. I’m worried that it will loose accuracy.

Any recommendations?

Thanks.

Here are several videos that explain tiling.
