I have not had a problem using my table saw (Ridgid portable) to cut ~ 5/16" blanks - after removing the guard. I use a very thin push stick in the back and just about anything on the side, along with a feeler board, to position the block during the cut. This way I get 3 blanks out of a normal Scout sized block. If I want 1/4 blanks I need to use my zero clearance insert, otherwise the wood will get trapped at the end of the cut. Its worth getting the blade nicely squared before you start. Using a good blade on the table saw I can get very good flatness of the wood blanks, which I think is critical (and needs to be checked prior) to the drilling operation that follows.
