On another thread, Matt requested some pictures of my Sears Contractor Saw setup. By no means is this a gloat, but since we get a lot of questions about "hot rodding" a contractor saw, I thought this could be useful for future reference. (Please excuse the appearance of my shop. The temperature here has been hovering on either side of zero lately and organization hasn't been a priority.)
Pic 0: A picture of the front of the saw which identifies its genre. Don't believe the "3 HP" for a minute. It's closer to 1.5, if that.
Pic 1: Here's the saw overall. I just added the router last weekend. The piece of pine is holding it level until I can add a folding leg to support the right side of the extention. Even without that piec of pine, the whole setup is surprisingly stable. The leg will ensure the right side doesn't tip down while I'm using the router. The mobile base is a 3-wheeled Rockler kit with a foot pedal on the front. It works great.
Pic 2: Another view of the right side.
Pic 3: Here's a better view of the router insert. I got the insert plate on clearance at Woodcraft!
Pic 4: There's the back of the saw. You can see the link belt. It's attached to machined pulleys, which also helped reduce vibration. I recommend a link belt with machined pulleys as the first modification to any contractor saw. Next should be a better fence. (Just my take.)
