Colchester Bantam Apron Control Lever Shaft

[Clem SayersParticipant @clemsayers49444]

Hello All,

I need to remove the control shaft from my Colchester Bantam (see picture) lathe but can't quite work out how to do it. Can anybody help, please?

Thanks,

Clem.

OK first off, why do you need to remove it ?

Is it because the lever has become sloppy ? If so then the fault lies in two screws that hold a plastic insert in the base of the start / stop lever and you don't need to remove the shaft.

Whatever fisrt thing is the tailstock end bracket needs removing. Its held by two imperial allen screws and 2 dowels.

The dowels are tapped 2BA so they can be extracted with a long screw over a spacer to allow the screw to pull the dowel clear.

The leadscrew is held by a Nyloc nut and has two sets of ball thrust bearings either side.

The feed shaft has an allen grub screw in the bracket end with a 3/8" ? ball bearing under it, again to act as a thrust.

Once this bracket is taken off the stop / start lever can be slid off after removing the screws that hold it to the apron.

If you need the whole bar out then the link to the stop / start switches under the lathe need to be disconnected, then it can be slid out.

The link is held onto the bar by a taper pin and it's easier to leave this in place and take the clevis pin out the vertical link.

If you need any extra info then post as I have one in bits at the moment and can take pictures.

Thank you very much for posting so quickly and so comprehensively.>>

The lever has become sloppy but, having partially dismantled the lever, I think one of the pins may have sheared: it is very, very sloppy (please see attached picture).

I would be very grateful for any pictures you can post.

Thanks, again.

Have to be tomorrow now, bit of a breakdown earlier tonight

Basically you have already sussed it, from memory and I blame the aluminium saucepans, they are just 1/4" dowels held in by 3/16" UNC grub screws.

I was one missing and it meant I could select one speed but not the other, new pin and screw and job was a good un.

Hello. Thanks for this. I fixed it last night. I don't think the pin had even sheared: I think it had just slipped out. I tapped it back in and did up the grub screw and now it's working again.

Thanks, again.
