Thread mill

[Dave Ward 1Participant @daveward1]

Hi All,

Back in the 1960's, J. A. Radford of Christchurch New Zealand, designed a thread milling attachment for the Myford Lathe. The drawings and construction series was published in the Model Engineer. I remember reading the articles but sadly don't have the ME issues in which the series was published. Does anyone recall the series? If so could someone let me know which issue numbers it was printed in. I now have a need for such an attachment and while I could design something from scratch, why reinvent the wheel.

Thanks so much for any assistance.

Cheers

Dave

Hi Dave

Searching for Radford in this index

Gives volumes 3331,2 and 3.

That seems to describe a "milling attachment" rather than a "thread milling attachment"

I believe issues 3437 and 3438 are the ones in question.

There's an article in 3549. Thread Milling Equipment and Operations

Radford is 3437 and 3438

A GEAR-CUTTING MACHINE
by T D Jacobs starts in 3529 and looks like a combined gear cutter and thread miller

"The pulley is a standard die cast product,
obtained from advertisers, and fits on either end
of the shaft, one end for hobbing spur gears, the
other for thread milling, spiral bevel cutting, etc.
The various collars cater for the endwise location
of the shafts. etc."

JAR did describe "A Thread Milling Attachment for the Lathe"; apart from ME, it is in the TEE Publishing book "Improvements & Accessories for your Lathe".

I believe the Quick Step Mill will do the same job.

Thank you all so much for the info and assistance. I'll have to look back in my very early ME's to see if I have those issues. If not I'm sure I can find them at one of the ME clubs.

Cheers

Dave
