Thanks guys this is really good info!

My Myford has a 3/4 Hp motor and it seems perfectly fine for aluminium too.

Some other questions would be

How did you lift and move it around? Engine crane OK?

Is it delivered on the stand or separates?

Where would the straps go on the lathe and should I even bother getting it with the stand, or are they too flimsy to bother with?

Anyone got the DRO version, and if so are there any problems with the DRO scales blocking anything?

I think the GH600 is probably the way to go. I even have loads of old motor oil I can use

Hi there, I'm selling my Myford and looking to get a slightly larger lathe. I will be using it for thread cutting, turning metric threaded adaptor parts about 3-4" in diameter.

The threads on the parts will be ISO metric 0.75mm, 1.0mm and 1.25mm.

I want to be able to switch quickly between these threads without having to play with changewheels like on the Myford which takes too much time.

The reason is that the threads are on the inside and outside of the part and I wouldn't need to remove it from the chuck. It would be batch-work.

I will use a DRO to get the part to the correct dimensions quickly.

My question is, would the GH600 or WM290V be better for this purpose, and which would be quickest?

I would like the ability to reverse without having to keep the nuts engaged if possible, and without the chuck falling off like you would get with a Myford.

Any advice or comments, appreciated, thanks in advance.

Hi John just to answer the lathe is without quickchange gearbox but it has the full set of metric change gears so quite a lot of work to switch between threads if say making an adaptor. On the other hand it's also got the full imperial range. The tailstock has metric scale and so do all micrometers.

Thanks for your help, Bill. I have a thread dial indicator with the usual 1234 on it. I'm guessing the little gear would have to have a special ratio or something.

Also, more importantly, I do appear have a motor capable of reverse. Here's the motor info plate. I would definitely need some sort of switch preferably a lever mounted on the lathe or stand enabling easy reversal for each pass, as you say. Any safe solutions you can suggest would be much appreciated. Regards, Nick

Edit: Although I've created an album, after hunting around a bit, it doesn't seem to have an edit option to add more images or tidy up existing ones, so I don't want to create a new album for every time I post. Anyway, the motor does appear to be reversible by switching the polarity.

Thanks Mike, I think the only option is to wind the chuck back by hand for each pass? I imagine if I engage the tumbler gears to reverse it, backlash would cause thread misalignment?

Hi there, the lathe is an original metric one with 0.05mm micrometer graduations and all the metric listed gears are included. That's why I was wondering about the leadscrew.

Hi guys, I've lurked on this forum for some time and finally joined, seeing I recently acquired a metric Myford Super 7.

I've many questions about these lathes. Firstly I was wondering what kind of leadscrew I have, seeing the tables look quite different to pictures I've seen online?

I'm after 1.5mm on this table

Zoomed out

Sorry the pics aren't orientated correctly they look fine on my phone.
