HI all I needed to lock the head up on my lath as i don't like drilling in to the lathe its self to attach things I came up with this on my lathe which is a compact 8 their is a bracket to mount the gear wheals on to drive the led screw so this was my starting point I got a peace of steel plate 3mm thick by 80mm long by 28mm wide drilled two 6.2mm holes on the center line 15mm from the top and the same from the bottom. I then got sum steel rod with a OD of 13mm by 100mm long I drilled this out to 8.8mm by 50mm deep then reamed out to 9mm drilled the lat 50mm 4.8 then reamed that out to 5mm. then i silver soldered the top tube on to the fixing plate I then started work on the locking pin I got sum stainless steel rod with a OD of 10mm
turned it dawn to be a snug fit in to the 9mm reamed hole I then turned dawn the back of the locking pin for the spring to go over I then drilled and taped this m5. the 9mm part of the pin is 15mm long I then put a slot in the front of the 9mm part to fit the tooth that wood engage on to the head stock gear silver soldered that in place I then thread locked a length of 5mm rod to the locking pin and the back of the 5mm rod was taped 5mm by 30 long I then made up the locking pin sparser and handle out of tufnol the spacer was taped m5 but the handle I taped m8 to fit m8 studding that was taped m5 right piks
