The SL 3700 sliding table saw from Ironwood Woodworking Machinery, a division of Stiles Machinery, features chrome-hardened guide rails to ensure the sliding carriage passes straight without lateral movement.  It features a 7.5 hp, three-speed main blade, and is accompanied by a scoring blade that is automatically adjusted via a controller. The all cast-iron, 2,500 lbs unit has a 10-1/2 foot carriage that is capable of cutting pretty much any size panel, Stiles adds.
