I did it a when we were first married and I wanted to make some of our furniture. It worked pretty well. In those days you could frequently find plans for such saw tables in home how-to magazines. I hung the saw from a 3/4 inch plywood table top with two 1/4 inch screws and wingnuts. I used adjustable stops at the front and back of the saw base so I could take the saw out to use in a conventional way and then put it back into the table and it would be perfectly aligned again.Use the edge of a piece of plywood for a rip fence. Set the blade cutting depth so the teeth come through the wood you are cutting ony about 1/16 inch. If you have an accident, it will be a small flesh wound. I did a couple of Instructables you should look at.https://www.instructables.com/id/Get_More_from_Your_Circular_Saw/https://www.instructables.com/id/Bench_Saw_Table_for_a_Wood_Lathe/There are things in both of these Instructables that will help you, including how to make your own miter gage.
