Sheraton Conquest Head Gear

[Quoll15]

I have done something really stupid and broken the fibre gear in the head of my Sheraton Conquest Lathe (ex-Army)

I am looking for a replacement.

I have tried "Australian Metal Working Hobbyist" - with no luck.

Tried 600 Machine Tools - but they don't respond to my emails.

Any help in finding a replacement gear would be much appreciated.

Cheers!

Neil.

Is it a straight cut gear or Helical,what does the bore look like.

Neil, if you can post details like diameters, number of teeth, thickness and all that other good stuff it is possible that someone has a spare. The other option is to make one up, but try the easy option first.
(Perhaps a photo of the broken gear too - we have some ingenious fixers here who may be able to suggest a way to repair)

Hi I believe its a straight gear , it runs on a splined shaft

Where is the damage? Is this your lathe or a catalogue photo?
As mentioned earlier, some dimensions, please. I have a collection of gears including fibre gears. Something may be adaptable - depending on the damage.

OOps, my bad.... just read through the posts and didn't check the names....

If you elect to remake a fibre gear ensure that is is cut from flat stock as opposed to cylindrical. The weave in cloth/resin material is radial in sheet material and axial in cylidrical, rendering the strength of the part critically different. "Micarta" is the brand name of the resin impregnated cloth composite with which I am most familiar.

BTW...my lathe employs similar gears which I have reproduced in acetal plastic with great results.

I have taken a photo of the gear - will get dimensions when I get the head apart.IMG_0039.JPG

I don't have tyhe skills or machinery to make a new gear - only a newbie at all this - not off to a good start so far ).

I am pretty sure another name for that material is Tufnol, a lot of Macsons used to have these gears also.
