The RouterMaster has been around for many years. Several years ago it evolved into the Torque Work Centre. It has the same vertical arm, outfeed arm and plunge mechanism as the Torque Work Centre.
The Torque Work Centre has the added advantage of the large table and the sliding carriage mechanism whereas the RouterMaster vertical arm is fixed.
However, the RouterMaster still fills a need for specific jobs or where workshop space is limited.
