Broken Myford ML7 Bull Gear
Hi all,
first things first, as a newbie I must say what a valuable resource your threads are. I admire the depth of knowledge you all so readily share with each other, many thanks.
In my quest to rebuild and then learn to use my 1955 Myford ML7, you've been a guiding light.
And now to what might be the hard bit and I appreciate it's a long shot ..... Before I slip the Kayak in the water and start paddling for the U.K. does anyone have for sale a back reduction gear (bull gear 65 tooth) to fit a Myford ML7 ? or know a fellow ML7 owner who might be able to help.
Since you guys seem to unearth some extraordinary stuff, I thought I'd ask before I get the paddles wet!!
Many thanks in advance for any help you are able to offer.

Hi Swarf4ages,
When you find one,please let me know. I have an ML7 with a similar broken gear. The ML7 has been in my workshop for about 40 years,so it has paid for itself well. I have some brochures and maybe some technical info. on the ML7. If these can be any help,I'll photocopy and forward them to you.
Good luck with your search. rgds marco.

Guys, cutting straight tooth gears is not a big drama if you have the cutters. If you can post a drawing and/ or pictures there might be someone who could cut one for you living near by. Depending on the damage, the gears could possibly even be repaired.

Depending on the amount of wall thickness there is between the teeth and the main body of the gear it is possable to replace the teeth with a ring.
The weld or pin repair is possable.
Machining a complete one would probably be the hardest to do.

Thanks everyone for your replies so far re: my broken bull gear, what a solid back up team you are.
It looks like pipeclay is the honourable 'Guru' with much credit to his name.
As luck would have it, the 'Grand Master' has already replied to my cry for help.
I'll email pipeclay as I'm also in Sydney and he's younger than me!!
Thanks again guys.

A huge thanks to 'pipeclay'.
I now have a re-cut fully operational bull gear.
If any members out there are stuck with broken gears etc, I thoroughly recommend getting in touch with 'pipeclay'.If it's at all possible to fix, he can do it. His depth of knowledge, skill and generosity of spirit are a rare find these days and I reckon we're lucky to have him on this site.
Many thanks again 'pipeclay', you're a star!!

Myford ml7 gear damage
Hi Pipeclay,
Following on from previous notes ,I come to you for advice. I have found time to repair/replace a damaged gear on my well used Myford ML7 lathe. Attached are three photos of the gear. Would you advise me. Can the gear be repaired or is it best to seek a replacement? I hope I'm not imposing on you,but your advice would be invaluable.
regards Bruce(marcopolo)

A steel ring gear would be the preffered fix in my opinion.
