Is that because it responds more quickly due to thermal mass?

I’d expect so.

Any particular reason for going for one from the states? Got to be a suitable supplier in the UK?

Have you checked how hopeless it is to bring 3-phase in from the street?

Hideous cost I reckon.... friend had 3PH put into a building and even them doing all the trenching and cable laying it was still I was to say something like ~£20k!!

On bigger lathes such as my Colchester Triumph 2000 the electrical motor is started and then runs continuously whilst the lathe is used, the control lever then uses a clutch mechanism to engage the drive and spin the chuck either forwards or backwards, the motor continues to spin in the same direction all the time.

On a M300 there is no clutch and the motor is started and stopped to spin the chuck.

In use with a normal full 3 phase power supply there would be little effective difference in use for most users. The issues can arise when using a static or rotary 3 phase convertor to power the lathe that they often don't like being started and stopped or it has to be done at the convertor rather than using the lathe controls (again the full reason for this would need to come from some one with more electronic skills than me), a lot of VFD's have a pendant type controller which with some clever wiring (cleverer than me anyway!) can be wired in to operate from the lathe controls which keeps things neat or mounted on the lathe. It can all be sorted but sometimes takes a bit more thought. Many VFD's will also start a motor gently to reduce the start up power draw and allow a smaller cheaper VFD to be used, mostly this isn't going to be to much of an issue but it can be for some things like thread cutting.

Sorry I could have saved you writing most of that.... I'm familiar with the lathe types, but I just wasn't seeing how it would actually affect the operation of the lathe in this kind of setup.

One point to consider with this lathe, is an M300 (or M250) is not a clutch driven lathe like the bigger Harrisons or Colchester's where the motor runs constantly, to stop or reverse direction to motor is stopped or reversed, from memory a clutch drive comes in with the Colchester Master size 5hp motors.

Typically most 3 phase converter are set up to start the motor and then keep it running in one direction at a constant speed, not sure this will work so well with this lathe. Not going to even pretend I understand the wiring required to make it work but I am fairly sure there are others on here who can explain it.

Not entirely sure what the difference is then.... just that it's started and stopped for any changes in speed/direction.

I’m thinking Britpart.

I do think there's a difference between simply not understanding what does what, and those who are just making things down to a price without a care for quality.

I have no experience of their offering and don't doubt your knowledge but I am rather gobsmacked to hear this. How can it be that they sell this quality of pin, yet appear to know what they are doing and remain in business and I think, are a popular supplier? Is it like the widely known distributor of almost everything, perhaps relying on volume and insufficient feedback / returns of shoddy goods?

Sadly I suspect people either don’t know there’s an issue… and then there’s also so many people these days selling all sorts that they just don’t understand in the slightest. That’s across all sorts of types of business’ too.

I've still got to finalise the purchase of the new motor. It's a 1989 LWB 461 G wagen, which is the 4x4 I've always wanted. It's solid and the only change is the engine. The 605 is a brilliant engine, almost as good as the 617. This one runs a standard mechanical pump and no intercooler, both things that will need to be addressed, although the latter is going to be fun, as there is air con fitted.  Worst case scenario, I have a 617 that needs a home. 

Needs a thread once it arrives with you!

I'm in the process of replacing the Disco, for a non Land Rover. I'll be sad to see her go, but she will be given, rather than sold, to someone who knows here well and will love her as much as I do.  My replacement vehicle (if all goes well) will be powered by an OM605, thus opening up a whole new world of diesel fun

Sad to hear the disco is going  

[Defender 90 300TDI Swivel housing preload]

I'd just pop the steering bars off and see what it feels like. The seal should leave a little residue on the swivel ball so give it a wipe and then a turn each way before taking the measurement and it shouldn't add much to the reading.

Yes, I am. Any other time it would be more of a problem for you as you’re a lot taller but after several back injuries I can’t stay still for too long without it hurting and I can see standing hunched over will be an issue. My work bench is the same, it’s a few inches higher than “standard” and it makes a massive difference for me….everyone else hates it though 😂

 

big boy isn’t it. Havnt really had a good look at it but it looks like it’s been violated with a grinder at some point, unless some come in an odd shape.

Sounds perfect then! And the same reason my benches are also taller  

[Buying a lathe]

In a nice way… Are you not short enough for it to sit on the deck and be the right height? Lifting one end at a time onto block with a pry bar isn’t too difficult. So it can sit down closer to the floor for now until it’s time to move it. 

[Buying a lathe]

I reckon it’s probably easier to just keep it on the floor. They’re not too difficult to get back up off the floor to get a pallet truck under again.

There getting the name boost ring because there sold with them silly boost pins that I personally would avoid like the plague.

And one particular emporium of over priced tat that calls them that as they don't understand what they do

I think the scariest thing is that they can machine it from a billet of 7075*  and sell it for £11 and make a profit.

*Allegedly.

Part of me is tempted to get one and get the inspection guys at work to point the PMI gun at it and work out what it actually is.

All good points. Lathe comes with a dead steady but I think it might be a dead dead steady as I had to pull it out of the tail stock because someone’s cut the tang off of the back of it. 

Some of them don’t have the bit on the end of the MT. The old Optimum I used to run you just wound the tailstock all the way out and it would knock the MT bits out. Live centre without the tang bit you just wound it back further. 

[What recovery gear do people carry?]

Ahhhh of course. Just never heard them named! 

[Seat Quandry]

I'm another that finds standard defender seats perfectly comfortable (6'3" and ~120kg). Have a try and see what suits. Good friend of mine started having terrible trouble with his back, tried all sorts to no avail.... until the car came round to be changed (Merc CLS). Back issues gone within a couple of days! 

[What recovery gear do people carry?]

What are you meaning by a shortening chain @mickeyw? Not familiar with the name! 

[Buying a lathe]

Fair point. I just used to angle the whole toolpost instead when required, making a note of the angle I'd set it to if I needed to repeat it.

[Winch Refresher Day]

Even though the 90 isn't on the road at the moment, I'd be interested depending on dates.

I'd also take a live centre over a QCTP. 

I've always preferred this type of tool post to the one @vulcan bomber mentions

Come on then, enlighten me. For someone who has never seen any recovery, other than with an old fashioned tow-rope in the olden days, what is the doughnut thing supposed to be used for?

They can be used like a snatch block, so attachment point through the middle and then winch rope round the outside and then back to the winch vehicle or other anchor point.
