Track Saw Spacers

Made a few 3" wide spacers for propping up the back side of a track saw track when cutting thin boards. Each block is 4" long and has steps for each 1/16" in height. Steps are 1/4' deep to support the track but keep it shallow enough to fit under. Have one that does 1" and thinner stock, and another that handles 2' down to 1 1/4".
