Yessir I used a 3/16" for the deeper groove and I believe a 1/2" for the wider, outer "shoulder". Different brands/quality of bits can result in different dimensions and the wood can sometimes give different results, so run some practice strips and mic the results. I imagine some variance is probably acceptable.
By the time I was getting towards the end, my bits were getting dull so invest in some good ones or be prepared to do a lot of cleaning out of the table, it was tearing more than cutting by the time I was finished. But it worked.
