4th axis project

[woodman08]

I wanted to be able to use my old rockwell lathe on the front end of the cnc machine .I found that by the time i bought a head and a tail stock ,then designed some sort of bed i may as well use a lathe i had kicking around.
First off i had to raise the router support then cut the cnc table (replaceable) and mount the rockwell .
I also ran some mock up tests with a wood model lathe .Then a 4th axis was needed and a stepper motor to drive the lathe .First i experimented with a belt drive which was fine then went to chain as the lathe had a threaded 1 in x 8pt left thread outboard shaft fitting the stepper here was tricky.But it works fine it was difficult as i asked a lot of people there opions and asked a lot of people about settings ,but its great. My biggest problem was to know what sort of steppers i had as there was no documentaion with my machine .Well i sorted it out ,now i have wiring diagrams ,parts lists and suppliers.It was a large undertaking and a challenge but its turned out well.Now i feel i know my machine and could tackle more
I'm cutting on the round .
