I use my sliding compound mitre saw to make taper cuts of 8″ or less on table legs. I usually make legs from 1 x “X” and mitre the corners. I cut an extra length of the leg to use for a jig. I clamp the extra length with the mitre towards the blade with a board over top that almost goes to the blade. This holds the leg piece in place when cutting. To cut the opposite leg piece, turn the extra length over. This method produces the same taper for all legs and is quick to setup and use.
