Gentlemen
I have decided to 'bite the bullet' in many ways it seems, the wife bought me a milling machine some time ago, it is time to re-animate it, [just waiting for a good thunderstorm didnt work], it is a cincinatti toolmaster of French parantage, have removed the spindle etc, gearbox for the head vertical feed has been removed, it has sustained some damage, a bent shaft and a worm/wheel arrangement that looks like it partially done its sacrificial job as it is ali, the teeth are showing signs of plastic deformation/shearing, hard to tell exactly as i didnt have te right glasses on but will later.
It is a small 3"x 3/8" gear that engages a worm.
Its apparent that it needs to be replaced.
The question; i have available a horizontal miller, a small dividing head, a lathe and drill.
Should i a, use mill and dividing head or b, make some kind of hob like the worm with teeth [lol] and use the lathe?
i'll add some photos after when i get my camera back, as well as some of the dimantling and bearing change.
Alternativly i could just buy one stock i suppose, either way gearcutting sounds much more fun and truthfully i have never even used the dividing head yet and the sin is i have 2 that were donated by my local scrap skip, along with the mill itself.
your thoughts are appreciated as i'm unsure of where to go next
thanks
