Hi Guys (And Gals)!
Not long retired and bought a C3.
Been great so far, but I did the unthinkable yesterday and carelessly stopped the chuck with the cutting tool!
I moved the tool post out of the way to give me a bit more room whilst drilling. The result is lots of banging sounds coming
from the gubbins whilst in LOW. High seems to be OK.
I am not sure how to get inside the headstock to have a look so any help and guidance would be appreciated!
Thankyou,

Hi and welcome to us  :wave:
The first thing that come to my mind is to put a peace of silversteel in the chuck and measure the performance with a dial indicator, then you know how bad it is.  :bang:

Hi Saw.
Thanks for the very quick reply! Do you mean to check for non concentricity? It seems fine in High ratio. I am thinking that I have stripped some teeth from the drive gear?

Hi Chris  :wave:

Welcome to the collective :borg:

It sounds like you stripped some gears. I have done this before... It does require a tear down to replace. You might be lucky and it is just the intermediate gear, which is easier to replace. What I did was replace the spindle gear with a METAL one and left the intermediate as plastic. Having a plastic gear is sorta like having an extra safety. Better a gear strip than something else break. The metal spindle gear guarantees it will be the intermediate gear that breaks.

Since you will be doing this, maybe you might want to consider replacing the bearings with tapered bearings...

Instructions on how to do this HERE. You can also see what you need to do to replace the gears...

I have been there, so if you need any questions answered, feel free to ask. Good luck!
