I have a pallet style table that I am building. I have a plate of contoured glass that will sit on top of it. To discourage it's movement off the table I was going to put some rubber feet on the base of the glass which will fit into some circular recesses.
I figure they would be very shallow. Just enough to stop the feet from moving but enough to have a gap between the glass and the table. 1/8th to 1/4 inches deep at the most and less than an inch in diameter. This is what the glass looks like just sitting on top the table.
Next is a picture with more focus on one of the corners.
The runners that I used both have bows in them. I have not issue with that since I take that as my table have a unique charm.
I the two best ideas I could think off are a drill press with a forstner bit or a plunge router. I currently own neither of these tools ( although I do have a fixed router and a table.)
Including the two mentioned tools, assuming they are viable, what tools (powered or otherwise) could I employ in creating a recess.
