I am a brand new owner of a new T8 and seem to be having trouble with the SE-77 Square Edge Jig sticking near the end of its travel towards the open end. It moves fine until it is about 10mm from the end with the screw knob. It looks like a problem with the plastic inserts in the jig and their alignment. If I turn the jig round (i know it cant be used this way) it moves fine along the full length of the guide bar. Very strange! Can anyone advise please. By the way the Tormeck kit seems great. Thanks Richard
