Glen,
Thanks for that reply. I think my saw is pretty much sound with no real problems. Haven't had any parts falling off or rattles. Very early on I had a heck of a problem with the blade tension. I would mount a blade, apply the tension I wanted. When I started sawing the blade would wobble and bend and the tension would be very loose. Worked on this or a couple hours VERY FRUSTRATED! I finally removed the table, mounted a blade and stated the saw. Low and behold I spotted the problem right away! The two bolts ( part #44 ) that hold the lower rocker assembly ( part #13 ) were loose. When you tighten the tension it would pick up on the assembly and stay tight - until the arms moved and the it would wiggle up and down with the movement of the arms . Tightened the two bolts and problem solved. Hole in the table is centered and the table is flat. Had a friend tell me to check that. He had heard of some tables not being flat. Biggest problem I have now is blade slippage. I flatten the two screws, clean the blades but after a while it goes south again. Guess it is due to the amount of use it gets. I do use a foot switch but I seem to be one of the very few that uses a on - off switch rather than a dead man switch. I am going to hook up the dead man foot switch and give it a try. Guess I just got comfortable with the other one.
