I have an old craftsman radial arm saw and I am in the process of trueing it up and I have done everthing the manual says,,but my problem is that then it cuts,,it actually goes thru the wood at a angle,,the blade actually pushes the wood back,,the manual says to move the rail system unloosten a bolt on the bach so you can move it right or left,,i have tried this and cant seem to get it to move,,i know its old and but can anyone tell me how to set the rail ,,or move the rail,,,,i hate to get rid of it,,,but I really would like to have it cutting square,,i did everything the manual says and layed a square on the table to make sure the blade runs true from the back to the front and it does,,but I still have the same trouble when I start it,,the blade goes thru at a angle and pushes the wood to the left,,i even changed blades but still no luck,,,,
