You might get lucky. It looks quite nice in the photos.

I have bought from him in the past, that seller is about the most expensive out there, and machines are stripped to the bare minimum of accessories.

The Myford 254S he is currently advertising didn't sell with the previous owner on eBay after a couple of listings a few weeks back, he now has it up for £5,950 (!), which is £2,400 more than it was on eBay, and now stripped of its 4 jaw chuck, travelling steady, and other bits.

I'm with Dave (S.O.D.). There are an awful lot of lathes in the world and most of them aren't Myfords!

If you want new then probably Chinese. If you want 2nd hand then a good Boxford or Colchester is hard to beat. If it really must be a Myford then be careful in your choice there are many vastly overpriced examples out there.

Athough I have owned a super seven for around 45 years nowadays I would go for a Boxford 5 inch centre height not 4 1/2 ins , they are cheaper currently than a myford though when I bought my super seven a Boxford just not affordable,though I would have preferred one as I had used a Boxford a lot during my apprenticeship and found they were very good lathes, a Myford is a very good lathe though limited by the ridiculous small bore of the headstock spindle,the Boxford has a larger spindle bore,another downside with a used Myford is a lot have been abused by ham fisted and really amateur operators. Both are good for model making ,if you intend motor cycle restoration or similar work the later Colchester Bantams are more suitable.

Hello All.

I am a drives and controls engineer, I have applied this knowledge to customer with machine tools all my working life. I AM NOT A MACHANICAL ENGINEER, but have a reasonable understanding and a real interest.

I have recently purchased a Myford Super 7 to restore and convert the spindle and main feed screw to CNC with positioning servo’s on both axis. I am fitting a 16mm dia, 5mm pitch ball screw to replace the main screw, this is the axis that will have one of the servo’s.

As a learning process, I restored a basic lathe and fitted a vector spindle, just to understand the mechanics and understand what I needed from the next lathe to deliver the quality I needed.

When the Myford is finished, I will sell the first lathe.

The main use of the lathe will be to produce clock gears and pinions, but also parts for my vintage motorbike.

The lathe is stripped and the bed is away being ground.

I am going through each assembly and restoring as I go along.

I selling the clutch and counter shaft, motor, all pulley’s including spindle pulley, rack, screw and apron and all other bits that I do not need. Some bits have all ready been sold.

My first question is the top and bottom slides. There is backlash, I think it will be the nuts as these are made of an alloy. Where would I get 2 bronze nuts to replace the original nuts?

I understand that backlash is not always a problem as it can be overcome with good practice, but I want to reduce it to a minimum

I am tempted to replace these primitive screw’s with rolled ball screw’s and include a locking mechanism on each axis as the ball screw will not hold position as it does not have enough friction. This would allow servo’s to be added on these slides. But this may be a job for latter.

I have many pictures I have taken along this journey and I will have many more before I reach the finish line. I am not sure about the norm of this forum but I am happy to share them.

I would welcome the answer to the above question.

I have been in the machine tool industry all my life. Reworked solid machines are far better than most new machines on the market.

Major global companies invest in reworked machines for this reason. (Landis grinders for example)

The S7 is well built, very solid, very adjustable and has a good spindle set up.

Unless you have the space for a much bigger lathe, the S7 is the way to go.

These are my opinions, but I am a drives and controls engineer.

.

That would probably depend upon the condition of the screw

If it's [significantly, and variably] worn, you will never get a nut to fit precisely.

If it's near perfect then it should be worth a try.

Hi

I paid £500 for S7 inc base from e-bay about a month ago. I have started a thread with a couple of photos.

The lathe was in reasonable working condition, but I have decided to completely rework it.

The great thing about Myford lathes is they are easy to work on, well documented, spares are available and they are well made with plenty of fine tuning possible with the adjustments provided..

Over the next couple of months I will be detailing the work carried out.

All the best.

Andrew

Sounds like a bargain Andrew, well-done. As there's a dearth of recent information about how long it takes and how much it costs to completely rework a Myford, it will be very helpful to others if you document what you do.

Cheers,

Dave

Hi

I have started a new thread – Myford super 7 Positioning servo's on Spindle and main infeed.

I have taken many photos or strip down and renovation, I have loaded a few in my album, not sure people will be interested in all of them.
