Table saw for tech theater class?

Quick note for people who may make there own saw guide. Make sure you mark the cutting edge of the guide with a thin marker or paint. This helps you to know if the cut edge (where you line up the cut) is still the dimensions you start from. Just realized one corner of my guide has slowly lost about 1/8-1/4 of an inch (over many cuts) and was altering the resulting cuts. The guide piece will still put the blade X number of inches away, but if that cut edge has been narrowed you alter the relationship of the guide to your intended cut.
