Can anyone tell me what this set-up is for an a myford I have just aquired ?

I can't find this in any books I have myself. anyone any ideas ?

Don't know if the rack operated tailstock is original or home-made. The rest of it looks like an home made power cross-feed and taper turning attachment. Looks quite nicely done.

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 -- Regards,

That's what I thought .My father in law has been model engineering in a fanatical way for 45 years and he has never come across this before. He has a meeting with his model engineering club in a fortnight and is going to take the photo with him. The lathe previously belonged to a Doctor and seems to be an original tri-lever in every way but for this attachment. Ikie

Intriguing though.

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) Ikie

The part that is built in to the back end of the cross-slide.. Does it move the cross-slide when it turns? If so in what manner?
Does the top of that part have any features about it that look as if tooling would mount on it? Perhaps a rotating cutter?
Am I correct in thinking that the rear shaft is keyed so that the saddle is still free to run up and down the lathe bed?
Since a changewheel banjo is connected to the motor end of the shaft, can we assume that the shaft turns at a rate determined by the changewheels and the lathe spindle?
Does it look like it is intended that different changewheel combinatins are intended to be used to allow different ratios between the lathe spindle and the rear shaft.
Any chance of close up pictures of the bit at the back of the cross-slide?

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. Ikie

Stick some sort of cutter in the rotating part at the back of the cros
slide, and a chair leg between centres, you should be able to do a bi of spiral fluting with that set-up.
The tailstock is standard Myford ML7, but fitted with the extremel well made capstan wheel attachment made by Cowells, they do come up o ebay from time to time (which is where I got mine from), but b prepared to shell out a few quid. I have mine set up on a spare ML7 tailstock to fit on the S7 when usin a coventry die head for making studs etc, much easier than trying t push the tailstock along the bed, its 3" travel is just about right.

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. -- Regards,

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. Ikie

Could you mount work on the top and use it to hob gear wheels using a cutter in the lathe - the gearing would then determine the number of teeth.

Looks like a relieving devuice with the cam and follower missing.

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?

Thanks Peter

As an approximate calculation it spins at about 25/1 of the head stock. I suspect it is for wood because of the speed even on the lowest gear it spins like a router.

I wish he could but alas he died hence I ended up with it. The poor bloke obviously loved the machine because he kept it in a bedroom. His garage,Kitchen,shed and bedroom were full of old model engineering stuff.It was like Christmas. I just hope to do his machine justice. ;o)
