I intend to buy this.. its going to save me money over having parts made (which is bloody expensive!) and a lot of time over trying to bodge with wrong tools (a cheap hand drill is not a lathe.. bearings fucked ). ***

https://www.ebay.co.uk/itm/360344827331

A small lathe should be able to do most things I want. A mill would have some advantages and be easier to set up and use? but lack screw cutting. The above looks like one of the better ones available?

(budget under £1000 inc tooling, to fit on decent sized bench and be moveable by me, without help)

*** I will probably end up with less spare time and money Laughing

For that price I would be getting a older 2nd hand lathe.

I assume you mean english? the problem with those is most are very big and heavy. The ones that are not are usually imperial gears/lead screw or very far away...

Alternatively Im tempted to buy a headstock, and XY table and some suitable lumps of metal for a Z column and other fixtures. I like the idea this would let me do in-place removal of things like exhaust studs..

Not necessary English, depends on the application, if it was me I would want the best 2nd hand lathe I could get for £450.

if you want to use it for essentially a big drill then fair enough. I would be looking at something like this if it was me.

£205 postage though - that makes it a ripoff for sure.

Have you had a look at the Unimat 6 in 1?

You can do almost any milling work in a lathe too.
Use your head.

Too big, perhaps not so bad without the cabinet but its got a pretty massive motor and pulley system inside. Also collection only from swansea...

This will mostly live in upstairs spare room, which is not ideal Laughing

£205 postage? where do you see that.

Unimat?!? I think they are made mostly of plastic Laughing would take me 10 seconds to break it, hand drill would do a better job.

That machine is junk. You'll find that the gib on the cross-slide doesn't fit properly, it allows the slide to lift and causes chatter and poor finish. They also have a habit of stripping gears and burning out motor controllers.

A lathe is far more versatile than a mill.

We have a bunch of lathes from the sixties and seventies in our workshop and two of six are in metric, old lathes aren't necessarily in Imperial.

I've never used a new lathe, but our new Mill isn't up to the standard of the old bridgeports despite them having 30 years of use on them and mostly sits there unused.

Basically I'd go for an old Colchester lathe if I needed one.machine.

I swear it said £205 postage when I looked last night Embarassed

It does look like a re-badged Clarke or Sealey though - and you might be right about the hand drill - the motor is only 550W.

I am looking for something similar at the moment, but I don't think this would be powerful enough.

I'm aware of the issues, but for the price it seems decent, with a time consuming possibility for many improvements..

Can suggest something else? this place is not far..

https://www.gandmtools.co.uk/shop/drummond-m-type-3-12-lathe-no-motor-80202370/
However I think that is probably much, much larger than it looks Shocked

Another one, but too far...

The Drummond one won't be that big, the table will be at roughly waist height, and it's taller than it is long.

Its not so much about power, most small lathes will be similar.. Rigidity of machine is far more important - and something the Chinese ones are known to be lacking, but probably adequate for me.. the bed only weighs 13kg Laughing

My issue is the limited space, if your able, get the heaviest thing you can find. Sealey and clarke, draper, silverline etc.. are big brands that do not make a single thing themselves.

Quote:
It is very important not to "over-motor" a Myford (or indeed any other lathe); any accident or dig in will have far more serious consequences - and if the machine is worked beyond its capacity, excessive wear will occur. Early ML7s were fitted with 1/3 hp motors, later ones with 1/2 hp - the latter a figure that should not be exceeded. Apart from the very first examples, the Super 7 has always been equipped with a 0.75 hp motor (necessary to pull the top speed of over 2000 rpm) and this too should be respected as an absolute maximum.

That M type is three times more than it's worth. I sold my dad's one with motor, bench and a stack of tools for £200 ish

Granville lathe in Woking. Probably 3 times the weight of that noodle and not metric but what a nice machine. Inside, outside and soft jaws on a Pratt chuck, that's got to be worth near the current bid price.

I did not see your post in time to buy it Sad I had looked through most of ebay, many, many pages Shocked annoyed I did not see it.

Im going to assume I could learn to live with inches or replace the leadscrew to convert to metric.. seems gear sets would be very similar just different combinations.

too far Sad

What do you actually plan on doing so often that metric screw cutting is a deciding factor?

For almost every job I've done in the last two and a half years a tail stock die holder has been more than adequate.

Perhaps not often but I would like to be able to cut large threads, 30mm+

Im also going to need a vertical slide, 4 jaw chuck, collets etc.. where to buy from - none are cheap on ebay, any good shops?

Ive got some tool bits, 3/8", 1/2.. then some massive 1" and 2" x6" lumps of HSSco. Some are ground others plain. So hoping I dont need to buy much.

There's a Warco 300 on Gumtree. It's a bit limiting in it's work envelope because of the cross-slide table but it does double-up as a milling machine, of sorts.

https://www.gumtree.com/p/lathes/for-sale/1128357888

One of these just today sold for £840 on eBay.

With the not often factor incorporated, couldn't you just say occasionally you may need to source things externally rather then fabbing everything yourself?

After watching https://www.youtube.com/user/colinfurze that dude cause havok I'm starting to itch to get something myself for a play as my skillset is similar if just not developed with machining. Fortunately the guy I was going to pester has already replied to you Mr. Green

ML4 in Luton currently very cheap. I know it's old and it looks rusty but it would clean up to work better than that noodle and hasn't been butchered. Apparently has all it's changewheels, original paint and for a bonus it will cut both Metric and English threads.

The ml4 went very cheap but too far for me... nothing close enough and really dont care to hire a van and collect. I want it delivered Laughing

Im probably going to get one of the 10x16 chinese ones with MT4 spindle.. 120-150kg and perfect size.

Had a look at these today, probaby ordering something for Saturday delivery Very Happy

The smaller machines, 7-14, 8-16 are tiny Shocked

https://www.warco.co.uk/metal-lathes-metalworking-lathe-machine/16-wm-240-variable-speed-lathe.html

https://www.warco.co.uk/metal-lathes-metalworking-lathe-machine/17-wm-250-variable-speed-lathe.html

They look good. I like the 250 other than bed is a bit too long. Trying to decide.. main difference is extra 100 quid for the bigger spindle and longer bed, 200w more motor..

Spec and bits included are quite a bit better than the amadeal version.
