Milling a Worm Gear Holder on a Lathe
I needed to mill out a slot on a holder that I was making to hold worm gear blanks whilst I cut the worm pattern into the gear. Not having a milling machine I used my mini lathe to mill a slot into the holder whilst it was mounted in the lathes tool post.
The picture above shows the milling bit in the lathe's chuck and the milled gear holder.
The milling bit was 6mm diameter and the worm gear blanks were 3mm thick. Milling the holder in the lathe it would be used in ensured that the slot was centred to the axis of the chuck.
