Frustrated yet again by the track saw track positioning always being extremely fiddly when wanting to cut small pieces off a larger piece of stock, I recalled a little aid shown by the "10 minute workshop" by Peter Millard on YouTube.
The problem is that ideally you want to use the plastic strip along the edge of your track rail to perfectly align to your cut line, with the piece of stock that you want to keep located under the rail. This results in the kerf of the blade fully positioned in the waste area, and the plastic strip helping to reduce any tearout. This works well when what you are cutting is as wide or wider than the rail itself, as you have the full bottom surface of the rail supported, and you can clamp the rail directly to the part you are cutting.
The problems with attempting to cut strips thinner than the rail is that you will often need to use a second piece of stock under the rail to support the back and ensure the rail is held flat to the stock you are cutting.
