I bought an inexpensive Craftsman 10" table saw on Craigslist, and the manual gives instructions for making sure both the blade and the fence are squared up with the mitre slot, and therefore with each other. And I've watched Woodworking #55 and #56 on Youtube which show essentially the same process.
But this saw has an aluminum table, and the sides of the mitre slots are kinda rough - not machined - and I'm just not sure the slot edge is a reliable surface to try to adjust from.
So I was wondering about possibly *visually* aligning the fence with a little groove found in the middle of the mitre slot, and then squaring the blade to the fence. Of course that assumes the fence itself, which is also aluminum, is straight.
Also, I was trying to think of a way you could do some test cuts that would demonstrate whether the blade and fence are aligned. Can someone help me with such a test cut?
