They sold them all off on eBay, I spotted it while they were on with knocking out all their stock of real service parts and have one on the shelf in the workshop for my standard Super 7 head should I use the head again and need the spare

I may be wrong but I believe they bought the name simply so they can sell "Myford Branded" Chinese products at astronomical mark-ups and that this was the driver for the financial input, I have seen little to disabuse me of this fanciful notion.

The initial behaviour of the "New Myford" on eBay might not colour your opinion of them but aside from being forced to back off by massive public opinion there was no evidence of any good will to the second hand marketers of genuine Myford parts or those selling new compatible parts, New Myford acted like utter Outhouses and never apologised.

Is it a Mill?

If you have chance of a Long Bed 7 it has a much deeper and more rigid bed casting than the standard length.

There is less distortion of the rubber required to get around a given radius so less conversion of energy to heat, whilst still maintaining grip and drive to the same depth as a standard belt. This type of belt was used in automotive applications prior to the adoption of Poly Vee for smoother running and less power loss.

When scraping the front bronze outer bearing bear in mind that spindle alignment was one of the things that could be adjusted/corrected by scraping during a factory refurbishment, busk that job and your spindle might point anywhere

Propellants are bought as powders, but not primers, unless you're talking makeup

Centre drills in the lathe, spotting drills on the mill if required (sometimes spot a layout to finish on the mill drill or drill press.

My centre drills have always self centred perfectly on the lathe, I can't imagine a way to stuff that up

Manually I'd use my rotary table with the closed end of the slot centred.

Collets up to 30mm are available for ER40, that can be very handy and Stevenson's Collet Blocks are available in ER40

Go with the back plate variety, you machine the back plate in-situ to accept it giving good concentricity and you will then also have through capacity.

I have half a dozen of the newer Aldi/Lidl ones with a single Lithium battery and they check out very well using my Mitutoyo gauge blocks, the batteries last for ages and I haven't had one fail yet.

The sensor area for mice is tiny and they regularly become confused when there isn't enough difference with distinctive artefacts between captured frames.

Mark,
If you're running it at standard plated power and speeds it will probably outlast you, I'm running mine with a 0.55Kw motor and 0 to 200% speed and thought a bit of Moly wouldn't hurt,

The FB-2 has a helical screw circulating pump which picks up at the bottom and pulls up to the primary drive, then allowing the oil to flow down through the gearbox.
If you run it until it's at a steady temperature you should have stirred the oil enough to pick up all the crud that will come loose and circulate.
What oil are you using? I went with a fully synthetic gearbox oil of the specified viscosity with a compatible Moybdenum Di-Sulphide additive.

Nick

Neil,
It's usually the other way around as you see above where those who prefer working to as close a tolerance as possible are pilloried for it

I have the gears for a gear train that gives me the option to work without gearing errors in metric threads, and it's quicker to set up than the approximation options ;D

Do you introduce errors if you have the option not to?

Cool, Siemens and ABB don't fault until running

Until you try to run the load a VFD doesn't output anything and will look normal whether there is a short or open circuit on the output.

If you think it's broken you won't lose anything by taking a look inside, start with where the power feeds in and look for anything unusual.

I don't "approximate" threads, if it's right it's right, if not then it's wrong.

I know lots of people are happy with a very close approximation, God bless them for settling! 

Where else will they "Settle" ?
