The rack operated tailstock looks like the Cowell attachment offered a
few years ago, can't comment on the other attachment but not sure that
it is a power feed as the spindle looks to be solely to provide power
to the attachment and not hold a chuck or other work holding device

Hi Mark The tail stock is an original from Myford 'Quite rare'
according to my father in law.
It's the rest that is puzzling us.
when you run it, the silver disk on the cross slide spins at a scary
speed. ;o)

John S appears correct in assuming Cowells made the tailstock.Ian
Bradley's The Drilling Machine contains  photographs but his is shown
drilling using an electric motor.
The cut away drawings are also shown for the modification.

Ian Bradley and his side kick Dr Norman F Hallows wrote as Duplex in ME
and other books.
Newcomers to the Myford might add Thomas, Cleeve, Tubal Cain, Sparey
and Radford among the producers of books but there is still a growing
number of articles despite the lathes being superceded.

No The silver disk just spins freely.The cross slide does not appear
to be affected.

It just appears to be a flat disc with the marking: 050.

Yes the saddle moves freely up and down the bed.While the disk
continues to spin.

Yes it does affect the speed by changing the gearing.But only from
fast to dizzy ;o)

Yes the drive gear can freely be moved and clamped in the desired
position.To what appears to be a fixed shaft gear.

I'll get some in the morning Pete and give you the link.

Thanks for your time much appreciated.

I had the Myford lever one fitted to my ML7 when I operated it.
I found it handy for such as Phil says and drilling fine holes, you
get more feel.
It was that useful I never even considered fitting the handwheel back.

It subsequently got further modified by fitting a duplicate set of
stop start buttons on the end of the lever so it was possible to work
it one hand on the tailstock and one on the lever collet chuck.

Later mod was a motor driven tailstock spindle to get the revs up on
small holes.
Tony Jeffree described the addition in MEW as he now owns my old ML7.

Hi Phil
You could be on the right lines with that one because when I got the
lathe home there did seem to be a coating of fine sawdust over the
saddle and bed recess.

Has the look of a relieving attachment to me.

Whats the ratio between the driver/driven gears? I did wonder if it was
some sort or arrangement for producing scalloped polygon turning, but
the problem with that is there doesn't seem to be anywhere to hold and
drive the material at the headstock end.

In which case it must be used only for something that can be mounted on
the boring table and wound into (a cutter) on the disc, and the cutout
in the boring table would provide a positive depth stop. Of course if
material was held somehow stationary between a couple of centres, then
I suppose it would be able to cut long keyways on a shaft as well. All
sounds like it would be spinning way too fast though.

You said the lathe was full of sawdust/wood shavings? Perhaps it was a
cutter for rebating home made biscuit jointers. I must admit to being
highly curious - can't the previous owner tell you what it is?
