Making or repairing pinion gears

Making or repairing pinion gears

Hi members,

I wonder if there are any willing and able people here that could make a pinion gear for me?
I have a Cowells tailstock capstan for my Myford ML7 and the pinion gear inside has got damaged teeth, they may be repairable but I doubt it.
I think the pinion is pressed onto the shaft but not really sure.
I am in Devon if you want to speak face to face.
I am more than willing to pay a fair price if you can do it.

I am not at the computer that often so may not reply immediately.

Let me know,

Re: Making or repairing pinion gears

Looks like the pinion is cut on the end of the shaft so there are three obvious ways to tackle it

1. make an entirely new shaft
2. machine off the remaining teeth & some more material so a sleeve can be eg loctited on in which the new teeth can be cut

3. build up whats left with weld & recut.

I'd go with option 2

It would help if you can identify the DP or module of the gear, This may help: … lator.html

What is the rack looking like - is it at all mangled ?

Once you have identified the gear any potential maker will know what cutter is required. I think a Brown & Sharpe style cutter would be best - I'm not sure I'd want to cut that with a single point cutter

Re: Making or repairing pinion gears

Thanks Anthony,

The actual tailstock ram (rack) is pretty well unscathed, I guess it is much harder material then the gear teeth.

Option 2 is the way I shall proceed.
The job has been taken up hopefully.
