I'm after advice about a few mini metal turning lathes, i shall be using it for making components for my airguns and for friends guns. I would like the distance between the centres form 200mm - 350mm. I'm willing to pay up to £400.
thanks
 
I started my model enginering on Unimat 3 lathe which is well made and accurate, the current model is the Unimat 4. You can get a lot of accesories for it so it's quite versotile and can be used as a table top machine but does not have screw cutting ability.

Axminster do a couple of small lathes either their Micro though only 250 between cts or the larger BV20which has 350 between cts and can do screw cutting.

Also worth having a look at some of the Chinese machines which come labled as serveral makes:

Hi Tom,

Welcome to the forum. :D

You may find the answers a bit slow for your question, this is a woodwork forum. :shock:
However there are some members that dabble with metal work as well, hopefully one of those will be along soon to give you some advice. :-k
 
Hi Tom,
What Jason has said….is spot on…..also plenty myfords around but they are always at a premium and most I’ve come across at the £400 price mark are at the end of their life.
For £400 I would look for a machine with gearbox with a bit of tooling…as it is tooling that can run away with the money.

For what you are wanting to do, I would be looking out for either a Boxford, Raglan Littlejohn, Smart & Brown…something heavy that doesn’t vibrate. Look for something with a collet chuck and quick change toolholders. Also try and find one with a gearbox. When you use parting tools etc this is where you’ll see the difference of a good solid built lathe to what the Chinese are offering now.
The upper price scale warco’s and chesters , excel etc are supposed to be better but I am probably spoiled with my Hardinge

I have 3 lathes…a Colchester student …a hardinge HLVH and a warco 180…the latter is still slightly out your price range if you go new, not one I would recommend. I bought mine at a show, I bought it to do small components but dont really get on with it

These would be smashing little ex toolroom lathes here and this one here
hope this is a bit of help

ive been looking at a chester conquest lathe, but i was wondering if this would vibrate a lot, because if it does then its really no use to me, as every thing has to be precise.
 
chester conquest lathe,

Difficult to use these words in the same sentence...but your precision might be different from mine.
remember 3 jaw chucks can be out as much as 0.003 before you even start turning, some even as much as 0.010
If you want precision then really it has to be collet work, you could change the chuck to a colllet chuck this would certainly help.

Precision Lathes you really want weight and rigidity...i have found neither with the chinese stuff.
I dont know the space you are looking to put it into, thats where the chinese stuff is popular...small footprint and nice and shiney


try and find one that wasnt made for a price but rather a purpose.

just my tuppence worth

I
 
Although the collet route is the way to go for precision the costs could start to go well over your budget, I built my traction Engine without collets, just spend a bit of time with a 4 jaw and dial guage if you 3 jaw is not true.

Collet holder & set of collets £100 upwards
Quick Change tool holder inc parting blade holder £100
Cutting tools either replaceable tip or Carbide tipped and a green grit wheel to sharpen them and a bench grinder £100
Measureing tools micromiter & calipers £100+ for decent brand name
Decent set of drills say Dormer 1.0-6.0mm in 0.1 steps £50.00

May also be worth looking for a second hand Sherline Lathe, these are made in the US and I have seen some very precise work come off of them . This may be of interest too :D

Jason
 
ok so here goes. at that end of the range if you are trying to do large
cutting you will generally get problems, and the older machines may
well need alot of work.

i notice you live in didcot, why not wander down to the railway centre, and ask one or two of the guys there whether they know of any secondhand ones, or even the local model engineering club. often older members,
or those unlucky enough to have had to stop will have machinery
and tools available looking for a good home.

course you could always try williams!!!!

it's also worth looking for a floor standing pillar drill, and any measuring tools that may be available. often sadly when someone dies these tools
just get dumped, so even with ebay around it is worth asking.

i would think from what you are looking at a 3 jaw self centring chuck
would be the ideal, but a four jaw is actually useful too. a lead screw
would be useful, and names like boxford are the ones to go for,
not least because they are almost bullet proof for new users, since
they were often used in schools.

make sure you hear it running, and check the gear change.

good luck

paul :wink:
 
Had another thought of a potentially useful link here. Dunno about your part of the world, but round here the classifieds in the local paper regularly have lathes offered for sale, often with all the goodies and sometimes with entire workshop contents.

Cheers, Alf

The link Alf showed is the 'bible' for most lathe users looking for info on the net.

G and M have a good selection....they vary in price but will give you a general idea what you can expect for your money

Like Jason also said...precision = pounds...you can get good results from 3 and 4 jaw chucks but if you can find a lathe with collets then that is the way to go.

for £400 i'd be looking at a boxford with a leadscrew...there are a lot without this function so ask.

Jason,
Yes...i got the warco mill cnc'd about a year ago....i have also bought a new (but secondhand) bridgeport interact cnc mill....(that was fun getting it into the workshop) and what a difference over the little mill.
so now its a bit redundant although its handy sitting rigged up with a 4th axis but not used much. The jet lathe i had, it only lasted about 2 months before i got the colchester. now i moved onto the hardinge.
I am supposed to be getting a new website but the guy who is building it for me has let me down so i'm still showing all the old stuff.
I bought a cracking J&S 540 surface grinder :roll: which is great for re-doing the blade bevels :wink:

I still kept all the woodworking equipe and i was thinking in removing the cnc gear off the little mill and building a cnc router about 1m square size. (just a good size for handles)
I am also going to look at a boxford 240tcl cnc lathe when i get home this time....luv this cnc stuff.
