Hello Rainbows,
The actual box section base measures 330mm wide x 640mm deep, above that is the tray which measures 440wide x 760 deep, the cross slide spindle sticks out a further 70mm to the right from the tray edge & I have mine about 380 mm from the back of the tray to the wall to allow for the motor & the ram travel but I think it could possibly be moved further back than that, you need side space to adjust the stroke as well on the left..
Graham.
