Thread: Colchester Bantam power feed problem

I have the same issue on my Chipmaster, which shares a common apron I think? From memory the article in MEW implied it was quite a task to resolve? If I test it by winding the chuck manually feeding up to the stop, the pressure builds up and then the feed drops out with a hell of a bang. Under power it just tends to drive the stop along the bed. I am just living without the feature although it would be a nice to have.

Hi Stuart

One of the members on this site is going to email the details of how to sort it. I'd be happy to forward them if you can message me with your email adress.

Hi Howard

Sorry for not replying sooner but all my notifications from this site are going into my spam folder.

I am indeed doing as you suggest but as my lathe has the facility to auto stop I would like to have it working if it is not too difficult a job.

Cheers Stew

This is my first post so I would like to say hello to everyone.

My lathe is a Colchester Bantam 800 mk1. The power feed drives either the saddle or the cross slide and works fine.

The problem I have is if I use a bed stop, when the saddle touches the stop lots of pressure builds up before the feed disengages, to the point where it has actually broken off a couple of teeth on the bed rack.

From looking at the parts list in the manual I can see that this pressure can be adjusted by altering the tension on two springs inside the worm wheel assembly.

As this adjustment can only be done by removing the apron I would like to know how to set this tension other than by trial and error.

If anyone has made this adjustment or knows how to make it, could you please help out.

I think this was covered in MEW 187 but I can't find anywhere to buy a back copy.

Thanks Stew
