Many people don’t have a lot of room in their workshop to permanently set up all of their tools on individual stands, especially something the size of a sliding compound miter saw. Most times you will pull out the tool you need, when you need it, and then put it away. If you use your garage as a workshop, I’m sure you understand the constraint on space. You can pull the car out of the garage to build something, but at the end of the day, you put your tools and projects away for the night so you can park your car inside the garage again.
One of the first tables I built for my sliding compound miter saw was a modular design made almost completely out of plywood. It was rather easy to build and didn’t take a long time to fabricate. Since the design is also modular, I could collapse the sides of the table and push it out of the way when I was not using it. The side tabletops are important on either side of the saw in order to support your wood stock as you are cutting it with the saw.
The video below shows how to build a modular miter saw stand very similar to the one I have. He points out a number of things in the video that can help your construction go even faster. The biggest help for you is the fact that most big hardware stores (Lowes, Home Depot, etc) will cut large sheets of plywood down to smaller sizes for you for free. When you go to pick up the plywood sheets, bring along your cutlist and ask them to cut it right there for you. That will save you a great deal of time, and if you have a smaller vehicle, it will also be much easier to get the materials home! Check out the video and reply with any comments.
