|The table is slightly larger than A4 size and has 2 pieces of right-angled steel that ride along 2 others attached to the base. These are well greased. The table is made from laminated MDF with a sacrificial 9mm MDF board on to.
||The X axis motor is mounted to the base. It has a 6mm shaft and uses a polythene pipe as a flexible coupling to a 6mm threaded bar turned at one end to 8mm. The pitch of the thread is exactly 1.5mm. The motor has a brass gearbox with a reduction of 11:1
||The min slotted opto switch is mounted next to the motor. As the table moves towards it, a small piece of angled meccano attached to the underside of the table breaks the light beam
||The other end of the threaded drive bar is supported in a piece of shaped nylon attached to the base to prevent it thrashing about. Secured under the table is a captive nut held in a wooden housing.
