Hobbolt Cutter

This is the second item i have put up so still a novice
On the first one i used elastic bands to give the down pressure
on to the tap
It works well once it get started
I used a 6mm tap and a old cordless type drill to turn it
It was printed in PLA so i have added a oiling vent on so you can keep the tap shank lubricated

V3 has 8mm bearing and center shaft clamp plus handle
