I reused loose parts that came with the combination machine to get a correct lock mechanism. I set two threaded rods into a dovetailed carriage nut and the tallest metal handle knob came from the removable score unit. Screwing the two knobs locked the crosscut fence on the sliding table but fine adjustments remained a bit tricky due to the base that tended to rotate when tightening the rear nut knob.

The wooden base was formed in an oak offcut and I machined v-grooves throughout the bottom so that preventing from troubles when locking. The fence holder enabled lateral adjustments but required a screw driver. The two bolts with their nut and counter nut purposed accurate repositioning.

The aluminium shaped tube may slide along the adjustable base releasing the two top screws and has the ability to hold stops. The grooves in the extrusion coming from an aluminium window enables for the locking of stops at any point but they also require tools. Actually the adjustable cross cut fence operates but is not convenient and has never satisfied myself .I typically use that accessory in conjunction with the mitre gauge.
