I am new here so I cannot post the photo I have - at this stage - but when allowed I will.

Interested to know if anyone has one of these lathes, I have no doubt they are imported into the US under one or more brands. 52mm spindle bore, 1000mm bed.

Interested in the accuracy - if someone has one.


Thanks Mal

Seems funny no one has chimed in, I can not help but this should bump your post back up to the top. I would love to see a picture or pictures by the way

Ah good, I have done my apprenticeship as a non spammer - here is the lathe in question. The Eximus is just the Australian firms branding - it will be something else through a different importer. Very interested if anyone has a lathe that is like this one. The real question is how accurate has your version been.

I have been told that Colchester Lathes are now made in Taiwan under licence and strict controls from the parent company - have other people heard this????

Well, I have a 13x40, and it is Chinese, not Taiwanese. On some level all lathes are projects, and you test them and adjust them to make them as accurate as they need to be for what you are doing with them. Mine needed adjustment when I got it in used but new condition just to meet my initial accuracy needs. I think just about all lathes now have accuracy in their bones, but it will take some leveling, adjusting, and perhaps some scraping and shimming to get the best from them. When we buy a bargain priced lathe, we are getting a kit that needs the finishing details it did not get at the factory because they were trying to meet a price point. There are still some high quality lathes being built, and they are as good as they can make them, as delivered. Unfortunately, the amount of labor it takes to do that raises the price to where only the fussiest and well heeled can afford them. How much do you want to pay and how much work do you want to do to it to get it to your expectations? The Taiwanese _generally_ put out better quality machines than the Chinese do, at a higher price, but not nearly as good as something like a Monarch lathe, which costs a lot more. The company that was making that really nice lathe for so little money that you want to buy went out of business. TANSTAAFL. (There ain't no such thing as a free lunch...)

Sometimes the very cheapest lathes have had corners cut badly enough that they are not really salvageable to a useful condition beyond melting them down and starting over...

Edit: Let me get off my soap box and welcome you to the forum, Mal!

Bob, thank you for utilising your soap box, us newbes actually get a better perspective by soaking up a bit of experience. I don't want to get into lathe renovation, I have three old motorbikes to look after, which is quite enough. At present I am still researching what my definitive level of desired accuracy is, but it is at least .01mm over 150mm when boring - for example.

Good thread cutting ability - current lathe has no thread chasing dial - that is now a must. Also it has shuffle the gears and then find out the chart in the manual does not match the table in the change cabinet and often neither are what is cut - well that has to improve.

Well back to the shed - some new parts just arrived from Germany.

Another question - what sort of boring accuracy is it reasonable to expect from a centre lathe?

Would it be unrealistic to expect the taper not to exceed .005mm???

Thank you.

Over what distance? That's about two tenths, so I suspect you'd have to go to some sort of grinding to hit it consistently.

I have the Grizzly branded Taiwanese 1640 that looks just like the RMLs, spec wise also. I can hold 1 to 2 tenths in steel all day long. Its only 15 months old and and light use, so time will tell, but for a budget import lathe its not bad. My 60 year old 10ee still holds 1 tenth over 6 inches on stock over 3/8" diameter. That lathe was retired 4o years ago when it had 54000 hours on the meter. Whole different planet so to speak.

If you can get it at a good price and realize it will never be a Mori or Pacemaker, go for it. I have no doubt in the hands of someone who did not own the RML themselves and did not care, it could be worn out in a few years in a full time shop. In the hands of the owner who cared about it should last for ever in a hobby shop or 10 plus years in job shop.

Thankyou Michael and Pstemari for you replies.
I bought a smallish Chinese lathe to get started - I have learnt a bit and have determined how much use I would have for a lathe in my hobby shop. Well it was probably a good choice - if it had been a more expensive lathe I would not feel justified in upgrading - so all good so far.

The given is I don't have more than 2.4m x 1m floor space in my workshop for the new lathe - so that sets a limit there.
The 1000mm long bed I have at present has not been a limitation over the past five years - so staying at that seems a reasonable limit.
My current spindle bore is 43mm and I find that limiting - so definitely want over 50mm - I would like 75mm but I know that is over the top.

So the tree big questions become;
I would like much better ACCURACY
Longevity of machine / QUALITY
VALUE for MONEY spent.

For instance I have looked at a Chinese lathe for $8000 Australian, a Taiwanese lathe for $10,000 Australian and a second Taiwanese lathe of high precision for $20,000 Australian - these were all around the same specs (give or take a bit).

Have looked on the internet for a high quality second hand lathe but mostly what I have seen looks like it would need restoring before I could use it with confidence - so that avenue is not throwing up any prospective solution.

Obviously in USA there are many more options - so for the present I will keep looking.

Cheers

I believe most of the ERL, RML, etc are made by Sunmaster in Taiwan, with different variations depending on the importer/country. The ERL are usually D1-4, so smaller spindle bore.
http://www.sunmaster-cnc.com/lathe.htm
If you look at the few reviews of these machines (ERL and RML), at this price point and what you are asking, I had spoken with an importer of these machines, and they are very high quality lathes. I do not think there would be any question with these being a significant improvement over what you have, and holding tolerance down to a few ten thousandth of an inch. I can do this on my much lighter Taiwanese 1340 lathe. So from an accuracy and quality at this price point, these should meet these requirements with no issues. Longevity in a hobby environment, well plan on passing it on to the next generation. They are very well made machines. Value/money, you get what you pay for. If you are looking at older iron with the specifications and expectations listed, I doubt you will find anything. The RML 1440 would be a very good choice, with the limitation that of a 52.5mm bore (D1-6), you would be looking at a very large lathe if you wanted a larger bore. Availability and too some degree support/parts would be a bigger issue.

Hi Mkjs
Thank you for your advice - yes Sunmaster sounds about right - I could not quite remember the name (knew it was Sun something).

The other machine I also considered at this early stage was the RML 1640 - a few things in it's favour over and above the larger swing.

But what other lathe manufacturers should I consider?

You have not mentioned the scope or use of the lathe, it would appear that your are looking for a machine with fairly substantial work envelope. Your are getting into the realm of much more expensive machines, and possibly the industrial type lathes and possibly CNC used market machines. The RML 14 or 16" swing would be the primary lathes in the new machine market, without spending a lot more. There is also the JET Elite lathes, but I have not heard nor seen any information on them beyond the brochure and hefty price. There are other manufactures, but as a hobbyist, I do know what would be reasonable alternatives.

Hi Mkjs

I have found that when you buy a bigger envelope one finds more that will fit in that had not previously been planned.
But one example is - my son and I have old BMW motorcycles - so each cylinder is a separate casting. I would like to be able to rebore the cylinders using the lathe.
I would like to be able to re- machine my flywheels. An work on the fitment of reproduction engine parts which are sort of right but need to be fitted with some care (which requires machining accurately - given the parts may be spinning at several thousand rpm.
Here is a part being modified to fit - it is being held in a holding block made partly in the lathe and partly in the mill.

18244632151_b64f0e365a_c.jpg
The other situation is that when I buy tools I would like to buy the best I can afford rather than work with tools that are maybe good enough to do the job properly. Hope that throws some light on my needs and personality.

Thank you for the link to the Jet machinery - I wonder where those machines are made? If the machines are half as good as the catalogue - they will be very good.

Regards

This is a lathe I found on the internet - does anyone recognize it by another name?
1000mm (40 inch bed), 56mm spindle, swing over bed 380mm

The real question is in which country is it actually made?

Have not seen that lathe before. The Jet Elite is Taiwan manufacture, example of Jet Elite EGH-1740 which has a 3 1/8" spindle bore. Seriously expensive.

http://www.moore-tool.com/product.php?id=1376

One thing to consider if you are looking for a machine in the near future, Grizzly machines South Bend lathes are being closed out and most are around 50% off of their list price. Even with shipping and import tax, they may be cheaper. These are also made in Taiwan, and probably are variants on the Sunmaster machines.

Interesting. The new SB machines never seemed to be quite worth the premium that Grizzly was asking for them. Not all of them are from Taiwan--the 8k, at least, is from the PRC.

Looks like they're discontinuing the Heavy 13, the 14x40, the 16x40, and the Turn-Nado models,

Agree on this, just did not seem to be worth the premium even for the less expensive range of machines and they did not offer much on the lower end. There are alternative machines for less, that being said from the few reviews I read, they were very nicely finished and quality machines. The Jet Elite machines seem to be of a similar quality and performance of the SB, but the Elite machines build/features seem to be unique to Jet.

The 8K is no longer listed as a model, the current SB lathes within the scope of discussion of this thread are made in Taiwan, just pointing out that they are now "affordable" and represent good value at the current deep discounts. If I did not have my current 1340GT lathe, I probably would have purchased the South Bend 13x30 or 13x40 lathe. I also looked at the SB knee mills, but ended up with an Acra/Sharp mill. There are other manufactures that sell larger machinery/lathes, but importing them into Canada may not be cost effective at the end of the day. A few examples:

http://www.kentusa.com/lathes-2/manual-precision-series/
http://www.acramachinery.com/Manual_Machines/engine_lathes.htm

Mal, it may be worthwhile to email some of the vendors above on machines and shipping, look forward to hearing what you decide.

G'day Mal, I had faced the same dilema as you, the only lathes I could find in Adelaide to look at were chinese and not very nice. I also heard and read a lot of negative comments, I finally got onto a mob in Melbourne, Modern Tools, they carry a range of Taiwanese machines, after much discussion I ordered a Liang Dei LD 1216 this lathe is quite well specked and is available with imp or metric leadscrew and all the change gears to cut both. Alos saddle can be set up as left hand or right hand.

I have only had it about a month but am very pleased with the finish and everything is nice and tight but still quite smooth. this lathe is a little smaller than what you are talking about, but it's as big as I can fit into the available space. I have yet to do any serious work on it but believe it will, perform as expected.

Thanks Bob for your comments. I did look at the Liang Dei machines. Then I got all carried away and spent a fair bit more cash and have ordered a short bed Colchester Triumph 2000.
Having just replaced failed bearings in the headstock of my 7 year old (domestic use only) Hafco lathe - I really liked the idea of pressure fed headstock and the replaceable automotive style spin on/off oil filter.
Also the quality of finish on the Colchester and also the feature set (while not better than other Taiwanese lathes - was exactly what I had looked for).

The other selling point for 600 Machinery was I was able to put my hands on the lathes I liked (unlike the Sunmaster - which are apparently very good - but I would of had to fly to Melbourne to look at one in the flesh). They ran the machine for me, allowed me to ask a 1,000 questions. Look at several different models and also let me see the Liang Dei equivalent which was also on the showroom floor. They also deliver the lathe to my workshop, set it up and run a basic familiarisation package/training on site. So I loved the lathe, appreciated the customer service and also liked the fact that I have future support just a 100k down the road -

I also spoke with Andrew at Modern Machinery in Melbourne - they were very helpful and carry a Korean Lathe - which looked like a beauty but at $55,000 it was really outside my budget - and also just a bit big - but it looks like a machine that would work for 50 years without a rebuild. Modern Machinery offered to fly someone up to supervise unloading of a machine and I could not fault their willingness to help.

So the Colchester is supposed to arrive in Brisbane this week and I am madly getting my workshop cleaned out ready for it's arrival. My old lathe has gone to live with my son - so he is happy. Now just that process of buying new tooling to suit the larger lathe - out with the 12mm tooling and in with the 20 to 25mm tooling.

So just a short wait now, if all goes according to plan.

G'day Mal, looks like you've done well, ah to have a colchester, our local trade school here in Adelaide had half a dozen of them when I was an apprentice, very nice machines. I think my Liang Dei will serve me well. the people at modern tools are very obliging and didn't rush me, answered all my questions, and gave useful advice with out being pushy, very rare these days.

I don't think the LD is pressure fed oil and no filter. I'll just have to drain it once a year and refill. that should be fine I'm not going into production just a hobby. Since i retired I've missed the machines.

I wish I had room for a bigger machine but that is a fact of life and also no room for other machines , would love a decent mill, but again no room.

Bob, I also had to compromise on bed length, so mine will be 625mm between centres - rather than the standard Colchester 1250mm. Now I can leave the mill where it works best.

I suspect, a shed is never bid enough and compromises have to be made.

Well our new lathe arrived yesterday.
Here are a couple of pics of the arrival taken by my fantastic wife. _ she even put up a little welcome sign to our new family member.
Still waiting on the electrician to do the permanent wiring - so he is just running on a 3 phase lead for the moment.
Technician came up and levelled the lathe for us and now it is just a steep learning curve on controls - and I can get back to actually wearing away some metal.

Thanks for viewing

I love the welcome sign. Funny you never gained any weight during the gestation period. LOL What dream lathe to own , glad ,envious, to see he arrived. Most or I call my machines females. But it don't matter he's beautiful . You must be on cloud nine , having thoughts on all the projects to be built.
Thanks for sharing your delivery , good luck and keep him oiled and cleaned.

Electrician came yesterday and he is all permanently wired in now to his own switch board. The coolant is mixed and pretty much ready - just got to check the level - might need another 10 litres - I put in 25 litres. Just waiting on some extra hydraulic oil for the head stock - level seems a bit low. This machine has a pressure fed headstock which also involves a replaceable oil filter - I guess when they filled it up - after running and filling all the cavities - the sump level is below where it should ideally be. Oil should arrive today.

Yes projects are on the drawing board - some modest ones to start with, just to get the feel for the machine. I know thread cutting is involved in many of my projects, one way and another. However first up is to machine up a carriage stop - I saw a good one on the forum which I will most likely copy.

So back to work and thanks for sharing the birthing experience.

YUPP , get to know your baby. Learn all the controls and ins and outs. Make some cuts set up your tooling , put him through all ranges and feeds . Run the machine to help smooth out any rough spots. Getting to know how everything moves or engages. Every shop I ever worked in I familiarized myself with each machine I would be running . Even the same machine in another shop may have its own quirks . Cuts down on making mistakes . At least I think it does. Again he's a beautiful machine.

Yes all is up and running except i happen to be away at present so not able to use "Wally" - but soon I will be back at the pointy end.

Keep on turning

Mal. You should post an update on your beautiful Wally. I'd love to see and hear how he's holding up. Love to hear how accurate he is after a year plus in your shop.
