I have a table saw by Ryobi which I bought in Germany. It’s not under warranty anymore. Anyway I noticed on a project the other day that my cuts werent coming out square and when I carefully checked my saw I noticed that the guide itself isnt square. When I set it to the length I want to measure it’s ok, but then when I tighten it down it goes off true. Any ideas or recommendations?

I’m interested in becoming more handy and would like to venture into the world of power tools (beyond power drills, that is). Home Depot has a nice Ryobi 10-inch table saw for the price I’m looking to spend. What do people use table saws like this for? Please do not ask questions in your answer. Thanks.
