routing of sink cut out
I am learning how to do a sink cutout for undermount installation. The counter top is 1.5" maple edge grain butcher block.
I have figured out that I need to trace the paper template in MDF, cut it out (sand, etc to make it perfect) then use a pattern bit to trace the cut out on the countertop.
The template says it is for negative reveal which is not friendly for wood around the sink, I imagine. I want a positive reveal. so I am wondering what is the best way to do this. Is there a pattern bit that would has the bit bigger than the bearing, so that after the flush cut you use it again allow an increase of the the template size on the target material?
I plan to use another MDF board to practice the cut out and check the reveal with the sink before operating on the actual material. Would this yield good simulation to check the quality of the template?
any other things I should know about? thanks..
