I have just heard that Mike George (Mike on here) has passed away after a long illness.

Mike was a contributor to Sporting Gun magazine since its foundation, and I knew of him from that magazine for many years.

Mike was a journalist, an excellent technical writer, a self taught engineer, and a lovely man that I never heard anyone say a bad word about.

RIP Mike

Whilst there are some red herrings thrown in, I believe the original question relates to turning tools for metal, not wood

Nobody would want to 'restore' a Boris bike, unless they 'restored' it back to the pond it was dragged out of

For the sake of accuracy (pardon pun), the big bore Super 7 and 254 Myfords are 26mm through the spindle, not 29mm.

Will the Boxford I linked on the first page meet your needs?

Here's a picture of mine, I defy anyone to find this much lathe secondhand, in this condition, for £2,200

If someone is looking for a lathe, the linked one would be a really good buy:

The seller services college and school machines, and when theestablishments inevitably sell them off, he buys them and sells them on.

I bought an identical machine to the one linked from him last year, and it had sat in the corner of the department unused for most of its life, and is virtually unmarked.

I suspect the one he is now selling came out of the same school. It also looks fairly unused.

A Boxford 330 in that spec would probably be at least £12-14k from Boxford today (they still make them, and all the parts and accessories).

It is a really versatile lathe - 13" swing x 40" between centres, with the built in gearbox and supplied change wheels, it will cut all the metric and imperial threads listed on the headstock chart.

For £2,600, I think it is a steal, he is open to offers, and I suspect a polite offer of £2,300 to £2,400 would buy it.

I have no connection with the seller, other than being a satisfied purchaser of its sister lathe last year.

Lathes in this condition are rare, getting rarer, and I am still puzzled as to why the X10 series modern Boxfords don't have a better following, apart from those owners in the know.

Someone on here should grab what I think is somewhat of a bargain!

For the wiring diagram, I will need to know if it is single or three phase, and whether or not it has the simple electrics, or the more complex version with the reversing push button starter, NVR and emergency stop button on the headstock casing, as they are all different wiring diagrams.

I can email the wiring diagrams, but before that, a couple of things to check:

Firstly, the changewheel/drive cover microswitch. The changewheel door is heavy, and it has a habit of dropping over time, and when it drops it isn't sufficient to release the door safety interlock. Your friend should tighten the door mounts before doing anything else, and make sure the door shuts securely.

If that doesn't fix it, check the chuck guard microswitch operation, as well as the changewheel cover one.

If it has a mushroom emergency switch (not the one on the headstock, a cabinet or floor one), check the mushroom is fully released by unscrewing the top and making sure the contacts inside are free to complete the circuit.

Lastly, if the above doesn't work, check the contactors are contacting/releasing properly.

Well, not really. Something of a tenuous link!

The engines in the B-2 are GE F118's.

The F118 is a derivative of the GE F110

The F110 has the same core design as the F101 fitted to the F-16 and others.

The F101 became the basis for the CFM56 civilian turbofan

The CFM56 was used to re-engine the KC-135 fleet's (B707 based, of course) from the P&W J57, and some B707's

You were entirely clear, I understood that.

A bit further than that, I have a quick car

I'm in the middle of nowhere, near Stoke by Clare

I'm a few minutes up the road from Chedburgh, can confirm there was nothing exciting aviation wise around, unless you want to watch every other plane on finals to Stansted being Ryanair!

Crikey, we have six serviceable Chinooks all capable of flying at the same time?!

Ooh, moderator to moderator handbags at dawn!

My go-to first reference is normally Metalworker's Data Book by Harold Hall, no 42 in the Workshop Practice series.

It's an old joke, that you fit to circumstances

Other search engines are available

But excusing the frivolity, as you say eye protection is a must. Brass particles in particular can ping everywhere.

Be careful about using that metal strip/rule method with inserts, particularly small tip radius ones, it is easy to snap the point off the insert if they are snucked up too tight against the rule, particularly if it is set low.

I set all my tool centre heights with a fine point dead centre held in a parallel sleeve in the chuck.

Svetlana Kapanina. Just one word, awesome!

There are loads and loads of suppliers on eBay, such as this:
