I have just installed floating wood flooring all thru my daughters house and now I need to put down 3/4 round molding against the baseboard to cover the 1/4 space left for expansion as per instructions on the box...the problem I have is that it will cost a lot for predone at the borg...I want to use my router table to make it for her...any advise on the size bit I need to get...3/4 bit doesnt seem to make a complete half moon or am I missing something..using 3/4 MDF....thanks alot
