I am starting work on a 14x17 conversion back for Deardorff S11. I need to rout a ledge or groove for the GG to the correct ANSI depth of 0.320 +/-
0.016. Setting the correct depth will be simple once I set up, but I am not a real woodworker. I have done work like this in metal on a mill.

What sort of bit is used?

What is the cheapest type of router to use?

I say cheapest, as this tool will have one purpose, this job, perhaps once.

I may rout the ledge in the 4 pieces first and then build the GG holder.
