Myford lathe indexing attachment (head stock)

Thanks Lads

Next up the spindle bearings ,, these were all bored in the lathe with the set up below ,, this ensured that they were all in alinement when fixed to the spindle bracket .


Outer bearing being machined .


and the worm end bearing blocks .







Then i made the index fingers ,,,,,,,, these as drawn would only open about 170 deg ,,,,,,,,, so a bit of a redesign and now they open to 270 deg



stamped up the index plates .


Next up the index arm mount ,,, this also needed a re design , as draw ,to lock it to the shaft a grub screw was used , straight onto the threads , not a good idea , so i made it clamp to the threaded shaft .

Then onto the index arm ,,,,, changed this a bit as i have more rows of holes and i did not like the nut as drawn on the top of the knob , i decided to sink it into the knob for a better feel and look .



made the index pin , this from silver steel/drill rod and hardened .


And a few assembly shots of were i am up to .

redesigned finger clamp ,
