Basically, Wot Neil said!! But some observations. Edison invented nothing apart from his telegraph device, that was not already working somewhere in the world, he merely obtained the first American patent on that thing by getting his team to come up with a quick working prototype and rushing to the patent office! Maxwell was a mathmatician, Steinmetz was a mathmatician and experimental engineer. The lone inventor is all but extinct because of the patent system. It has become possible to patent ideas without any proof of concept, and so teams of company scientists are involved in this process daily, (IBM are one of the biggest) with the result that no company will fund research into any area that already has patents owned by another, and if anyone does come up with something that works, they can use their legal and financial clout to make your invention come under their patent. I have a friend deeply involved in traffic management systems, and he and collegues worked on an idea for several years, which they patented, for a bus navigation system, which they showed to a major european bus manufacturer. They changed a chip in it, stole the device, and said, ok so sue us! The possesion of a patent means nothing unless you can afford to defend it succesfully in two or three cases, and as Mr Dyson has found out, that costs millions. There is no such thing as Artifical intelligence, that is the hype that makes people believe it is clever. It is merely a machine functioning as it has been programmed, and you can program a machine to write its own program, but it is not capable of thought, it is just crunching zeros and ones very fast. The self driving car, like nuclear fusion, is only twenty years away, and always will be! It requires consciousness to drive a car, not just inttelligence. I have been looking for some proof of this for some time, and found it in some recent discoveries in Neuroscience. If you take a subject with a damaged visual cortex, who has no vision whatever, but has perfectly working eyes, and sit them in front of a screen, you would imagine that you could play anything on the screen and it would have no effect on them, and you can, except that if you show them an attacking predator, they immediately recoil from it, but when asked, say they saw nothing, and do not know why they recoiled. You need this sense to drive a car, how are they going to build that into a computer? By the way, whilst there are theories about magnetism and electricity (and gravity) no one has come up with an explanation of what they are and why they occur, they have merely been quantified Tesla, Heavyside, Steinmetz and Maxwell all denied the existence of the electron, and their calculations are no less correct for it.

Hi Grotto, you can always buy an MT2 to MT3 extension socket **LINK** but it will take up a little of space, so will depend on what length of bed you have.

[Ace ChandlerParticipant @acechandler49785]

hi folks, another noobie mill question.

Looking at the sieg x2, it looks like ARC Europe sell it with a normal drill chuck, do I need to look into purchasing a collet chuck too?

I didn't know if the normal drill chucks don't have tough enough bearings to cope with the sideways load when milling

I guess if the answer is 'no, you don't need one' – then it begs the question of at what point would I need to buy a collet chuck? e. g. are they only needed for heavier milling cuts?

Thank, ace

The Arc Euro Trade Catalogue is worth getting, although it will encourage you to buy more tooling / accessories.

The prices in Catalogue No 10 are now out of date, but are a useful guide.

Hi Howard,

Unfortunately, we have run out of copies of our Product Catalogue No.10.

Our website is up to date with products and current prices.

At present, we are unsure when the new Product Catalogue No.11 will be released . . apologies.

The video shows the issue. The cross slide has play in it. It's not backlash, it's a physical movement of the Y axis of the cross slide. The carrier and the bed are solid, but then the leadscrew for that axis moves loads.

Check too that the cross slide feed nut is not loose on its mountings. And that the graduated collar and feed handle arrangement are nipped up to eliminate back and forth movement of the feedscrew where it mounts.

Does look like a bit of movement on your video, but it's not unusual for a used lathe to have 15 or 20 thou of movement there. It does not particularly affect normal turning operations as long as you remember to wind the cross slide out past the backlash and reset to the correct mark if wanting to reduce depth of cut etc. Even new, there will be some slack there and this procedure need to be followed.

ArcEurotrade has a kit, and fitting instructions on thier website IIRC, for a roller thrust washer to go between the cross feed screw and its mounting to eliminate all slack there. (But there will still be some slack in the nut etc as per usual.)

[Howard LewisParticipant @howardlewis46836]

Have never had anything but satisfaction with Arc. Ketan and his crew are friendly, helpful, and scrupulously fair.

(Haven't met many suppliers who say "If it doesn't work out, send it back in good condition, for a refund" ).

A C3 lathe is about as much as you can lift, 40 Kg net, 50 Kg gross. It may, at first, seem bigger than you need, but you will find other jobs that are too big for a C0 or C1.

The Arc Euro Trade Catalogue is worth getting, although it will encourage you to buy more tooling / accessories.

The prices in Catalogue No 10 are now out of date, but are a useful guide.

We all have some accessories that seemed a good idea at the time!.

My advice is to use High Speed Steel tools for the materials that you are likely to use. To get the best out of Carbide tools, they need high speeds, and were developed for Industrial.are

(Already you are on the slippery slope needing a bench grinder! )

Further advice: make up a centre height gauge. It will simplify, and speed up, setting tools to the correct height, so that they cut correctly..

If you want to cut threads, other than with Taps or Dies, read up one of the books on setting up the gears, such as

Workshop Practice Series No.3 "Screwcutting in the Lathe" by Martin Cleeve, or Brian Wood's "Gearing of lathes for Screwcutting". This is very likely to lead to you making a mandrel handle , for jobs needing slow speed, and high torque.

Back copies of M E W are a good source of ideas, and methods.

Finally, do ask for advice / help on here. Advice will be given freely and if you have a real problem, the chances are that someone will be close enough to come and help in person.

Good Luck, and Enjoy!

[SillyOldDufferModerator @sillyoldduffer]

Pretty much as Thor said.

1. I am a Radio Amateur and used a mini-lathe to make antenna parts. The main restriction is the size of the lathe, notably the spindle hole. Don't expect to put threads on a scaffold pole! I agree the C0 and C1 size are too small, big is better.

2. ArcEuro are trustworthy with a good reputation, but check the specifications carefully. Mini-lathes differ at the detail level, things like the motor type (brushless best), motor power, accessories provided, carriage, steel vs plastic gears etc. Sellers sometimes drop prices so the Arc SC may be on offer.

3. Mini-lathes will turn steel, beware of random scrap, quite a lot of it isn't machinable.

4. Controller problems still pop up but they seem relatively rare these days.

5. Metric unless you have a specific reason for preferring Imperial like scale modelling Imperial prototypes, working to imperial plans, or have access to lots of imperial goodies.

6. I used Carbide mostly – for a beginner indexed carbide avoids the need to sharpen HSS.

Delivery indeed dropping a pallet at the end of the drive. Some drivers more helpful than others, but perhaps safer to assume the worst. 40kg Mini-lathes are an easy two person lift. They weigh about as much as a small woman/large child but are awkwardly balanced. I am an unfit weakling and couldn't lift mine safely from floor to bench level. (In an emergency I would have risked it, but I value my back.) Easy enough to get off the pallet and walk end by end across the floor. I used a box, workmate, and several lengths of 2×4 to raise the lathe step by step until I could slide it onto the bench. Later, a friend and I easily lifted the lathe off the bench and carried it 40 metres to plonk it in his boot. He lifted it on his own when he got home, but he's 15 years younger than me.

My machines – mostly Warco – all worked out of the box on delivery. They all needed a little fettling, but it was trivial stuff like increasing the depth of the locking hole under the High/Low lever to make it more positive, and adding a plastic strip to stop swarf getting inside the control box via the leadscrew. (Recent lathes come with a grommet.)

Edit forgot to mention noise!  Possible to listen to a radio at ordinary volume when using mine.

[Thor 🇳🇴Participant @thor]

Hi James,

Welcome to the forum.

1. Many model engineers use a Mini-Lathe for their work, so I guess it might be sensible for you to buy one.

2. I have bought several items from ArcEuroTrade and have always received excellent service, I don't think
you need to worry.

3.Brushless motors should be Ok.

4. The older Mini-Lathes with a brushed motor sometimes had controller problems. I have an old Mini-Mill
(same brushed motor and controller as older Mini-Lathes as far as I know) that is over a decade old and
have had no problems.

4. I live in a country that adopted the metre convention in 1875 so I would say a metric lathe, others may
have a different opinion.

5. For cutting aluminium and plastic HSS tools should do Ok, I myself use both Carbide and HSS tools
depending on the job at hand.

I am old and have back troubles so I wouldn't carry it up a flight of stairs alone, I would ask a friend to assist me. Good luck.

Thor

[James Bennet 1Participant @jamesbennet1]

Hello,

I am a radio amateur, and am interested in buying a small lathe on which to produce small antenna parts (predominantly in aluminium or nylon). And also to learn some new engineering skills while I am at it.

I've been looking at a number of different lathes in my budget (Total budget of £750 including tooling), such as the Sieg C0 and C1 Micro Lathes, the Proxxon FD 150/E, etc… but they seem to be quite limited, and overpriced, so finally I'm leaning toward the Sieg SC2-300 Mini-Lathe from ArcEuroTrade, as I figured one is probably best buying the biggest machine you can afford/fit, right? It would also still leave me a fair bit for some tooling.

I don't have any previous experience with turning, so I wanted to validate a few points – Any feedback on these would be greatly appreciated

1. Is this a sensible choice of machine, in the first instance.
2. Is ArcEuroTrade legit? I ask as they seem significantly cheaper than both Axminster and Warco for broadly the same machine. Would that imply a lower level of quality control on the machines they import?
3. I don't plan on turning steel, so the 500w brushless motor should be fine, correct?
4. How reliable are these machines – I read some older models had issues with faulty PCBs? How much preperation and fettling do they need out of the box, and in order to produce reasonable results?
5. Is metric the way to go?
6. Carbide vs HSS tooling?

My second query is around the installation of the machine.

I live in a (first floor) flat, so I would need to get it up a single smallish flight of stairs. I figure this machine is about the largest that I could fit through the door and up the steps, but at perhaps 45-50KG, what are my chances of lifting that up myself anyway? Can anyone share any experiences? I assume the delivery guy will just drop a pallet at the bottom of the drive?

Any other advice would be most welcome – I don't want to buy a lemon

If Ausee has a link to ARC as they say they do then Ketan needs to take a look at some of the stuff they sell ! I got a set of Stevensons blocks from them that were ground with one face at a different height to the other block.,mine are metric and I don’t think the original Stevensons blocks were metric .

Ian.

Hi Ian,

Derek was referring to Stevensons collet bock/s, where as I believe that you are referring to Stevenson's Metric Blocks– 10-20-40 etc. The Stevenson's Metric Blocks are sold as work holding, predominantly used as a kind of low cost jig as JS intended for its use to be. Many of the imperial ones which were in the market place at the time of JS's metric creation failed to bolt together, and what was available was in imperial only. So, JS created METRIC ones, which really did bolt together using metric threads, geared mainly for metric users. It is true that some of the faces have minor differences in height. They are not sold as matched pair, as their main purpose is for use as just stated. However, I can see and understand your point of view, which had also been discussed with John when he was alive. At the time he was not overly concerned by this observation, suggesting that if this was an issue for the user, they could always modify as per their need. As he is not around to go into detail, this is a summary of his comments. However, to reduce the chances of this kind of comments arising, I had put a request in place in the factory that once these type of blocks are ground, the packer should try to pick two blocks in sequence, still packing them individually. Still, they will not be guaranteed to be a matched pair… again because of the main purpose of use being as a low cost jig.

This explanation may or may not meet a persons requirement. At preset, to the best of my knowledge, AUSEE buys all the STEVENSONS range from ARC.

[SillyOldDufferModerator @sillyoldduffer]

Searching for 'collet block' on ebay returns many sellers of items remarkably like the original collet blocks as still sold by ArcEuro. They are all in China. May be from the same factory, or copies, perhaps illegal. (John's genius celebrated by imitators!) I think the only way to confirm the quality would be to buy a set.

These days it's possible to save dosh by buying direct from China. The disadvantage is what happens if rubbish turns up! Buying from a British supplier provides consumer protection and – imperfect world though it is – part of the service provided by Arc Euro is filtering out the worst and putting mistakes right.

Can't help with the payment problem. Many firms are reluctant to take cheques: they are untrustworthy and hideously expensive to process compared with an electronic transaction. I would much prefer not to have credit cards and internet banking because the electronic system is run by a bunch of slack Alices and poorly regulated. But it's so easy to use and so hard not to get sucked in. So far I've not had a problem…

Visited yesterday for the first time. Very enjoyable. As others have said it was very disappointing to see that Warco, Arceuro, Axminster etc didn't show up. I was looking to buy a lathe and wanted to compare. Their loss I suppose because Chester got my money in the end. Spent a good couple of hours looking around the trade stalls first, managed to bag a few bargains! Then looked at all the amazing models. The Bentley was definitely best in show for me, the detail was just superb. I took lots of photos so if anyone want to see let me know and I'll try to upload a few.

[Michael GilliganParticipant @michaelgilligan61133]

Derek,

I doubt you will find a Stevenson collet block anywhere other than Arceurotrade, unless you buy secondhand.

[DalboyParticipant @dalboy]

Where can I buy descent set of Stevenson collet block other than Arceurotrade.

I have seen them on E bay but the quality does not look that good

Please note this is not anything personal against the company just it does not allow for my payment method

[Andrew EvansParticipant @andrewevans67134]

I enjoyed it today. It is very noticeable compared to a few years ago that there is a lack of traders with new machines on display. Chester had a small stand but no larger machines. No Warco, Amadeal, Axminster or Arceurotrade. I think the only lathe for sale was a repainted Myford. Nothing relating to 3D printing or CNC. If you want to by machine tools these days it seems like the only option is online.

Some of the models are amazing – my favourite was the 1/3 scale supercharged Bentley engine and gearbox.

[Chris Evans 6Participant @chrisevans6]

I have a Loctite catalogue giving all grades/uses. A good reference is ARC Eurotrade's catalogue which gives their brand alternative.

[JasonBModerator @jasonb]

Even though I have a 50mm facemill I still tend to use a flycutter for 98% of sizing up stock. Only really get the facemill out if it's an iron casting that may have some hard spots in it which blunts the HSS.

Most of the time I will use the middle size from a set like this with a 6mm toolbit, not to hard to grind yourself ( see Milling for beginners) or ARC will sell you a preground bit. Works out very cost efficient as a bit will take many touch ups. Similar flycutter is easy enough to make, I think Ron made one.

On your SX2.7 I would suggest two passes to get to your required size, ideally one each off opposite faces, about 800rpm if using that size flycutter which will be swinging 35-40mm at the tip.

With the 12mm cutter you should only need 3 or 4 passes 10-7.5mm wide on each at the full 1.2mm deep.

Hi I bought a rotary table for my 16v mill and it is a 4 inch size and it has done every thing I wanted but the clamping slots which are cast on to outside of casting cause clamp studs to slip as I tighten it sometimes and I wish I had seen the one at Arc euro which uses slots to clamp with i also had to make an adaptor plate for my one to but th Arc one has one. Dont forget to buy a chuck to fit and make sure it is a low profile one. There is an adaptor to fit a dividing plate etc to there one when you need it.

Can you tell me what bearings I need, and where to get them.

I used F8-16M (2 per axis) from ARC. (Do ARC keep order history for ever?) Russell's drawing showed the same size and the same general arrangement. Though I did not modify my leadscrew. Diagram 4, part 23 of the SX2.7 looks much the same.

IF I recall correctly, the fiddly bit is getting the outside bearing slightly proud so that the handwheel neither binds, nor shows a large gap.

[Nigel McBurney 1Participant @nigelmcburney1]

Use a ER collet in a hexagon collet block (from arc euro trade) those collets will grip anything,dont try try using precision lathe collets ,usually morse taper,trying to grip too tightly can spoil them. larger ER collets will even hold 1 1/8 Whit taps without slipping ,and they are superb for making double ended Whitworth studs,no more problems with slippage. Best tooling I have bought in recent years as I do a lot of restoration work, I use ER 32 and 40 sizes
