Hi Joe
Here's a set for 8.oo dollars and it has the sizes you need, I use them all the time and they work great...
Just clamp the stock to the drill base table, drill a 1/8" hole then use the 1 3/8" bit then the 1 3/16" bit to drill the center hole out all the way..it's a very fast way and it works every time...and I'm sure once you do it a time or two it will be the last time you buy any base plates for the router or the router table..
Just a note,,, a square sub base plates are the best....then they can be used in many more ways, for a strait edge,to hold bearings on the corners for M & T sloting, etc.
