• The reason we stopped the preparation service was:
  • a. cost and not too many people were prepared to pay. Even then, we had a six months waiting list
  • b. some of our competitors put out negative marketing comments which suggested that our preparation service was either not necessary or in some way made the machines inferior then theirs, which was wrong thing to say considering that assembly was in the same way
• Once we stopped the preparation service, our sales increased tremendously.
• The point is, at this size of machine, the customer decides what they want to pay, and this is what is available for the price.
• your machine came from the same batch as Jasons!… if he took his machine apart, I have no doubt that he will find similar/different issues.
• Sales for these machines in the U.S.A are at least 3 x the whole of Europe. Most of them want the low price, and many work with what they have, and some dismantle and do what they want to the machine to get it to their precision requirement.

All I will say is that you have a great machine at a great price. You can watch what ever you like on youtube and listen and believe what ever you want. That is really up to you, and I say this with the greatest of respect.

Hi Neil This is my first post!

Just to let you know I bought a KX1 from Arc euro just over a couple of years ago and I am very pleased with it, it's a lovely sized bench top machine, you'll get loads of fun out of it.

Although I've had it a couple of years I've not fully managed to explore its capabilities, mainly due to operator error (me!) and computer software and hardware melt downs which set me back months! The only one mechanical issue I've had was a wobbly spindle early on which was quickly sorted by Ian and Ketan (it was at the same time as Johns illness).

So this year I will be getting more adventurous with the KX1 because I've just ordered a 4th axis for it, it should be delivered tomorrow.

I'm not sure if I should apologise for re-opening an old post as many forum users seem to apologise for doing just this, but it seems better to me to keep related topics together – it makes searching for help so much simpler.

Anyhow…..some time ago I bought a threaded pull-through device from a local supplier for 5C collets (nothing to do with arceuro I'm happy to point out) to use in my lathe.This turned out to be an abortion of a thing, Slow to use when moving stock forward for the next item and prone to unscrewing in the wrong places.

I then read a forum post where it was suggested that a Stevenson's Collet block could be set up in a 4-jaw chuck and used as a collet chuck that was opened and closed from the front end of the lathe. This idea worked absolutely brilliantly for me. Fast and convenient.

Problem solved – except how can I hold square-section bar?

In another thread by the late,great, Earl of Bridgeport and Sumpwater he commented that Jason B had proved that an ER collet could be used to hold square and hexagonal stock, but I am unable to find that reference.

Alternatively is there a way of holding my existing 5C collets from the front of the chuck i.e. by compressing the front of the collet into a taper, in the same way that ER32 collets are closed?

Regards to all, Chas

I have both 1 inch and 22mm bore cutters.

For both, I machined 3MT stub arbors (from Arc Euro in my case) By machining the ends whilst located on the Taper, the register is concentric, and can be as long as you require. The clamping washer includes a countersink for the Allen Screws, to maximise clearance under the arbor.

Same technique used for arbors for Slitting Saws.

Steve, would it help if you had more table area so that you can get workholding clamps out of the cutting envelope? I don't know what size the Emco table is, but over on the Denford forum someone described adding the Sieg long X1 table available from Arceurotrade on top of the Novamill table to give more length and I think a bit more width. Of course it eats up a bit opf daylight under the quill. You could do something similar by using a slab of aluminium or steel, with threaded holes outside the work area for clamps.

By the way, you don't really need to reduce the stepper current as you describe, steppers are very tolerant of hitting the buffers if you are moving slowly.

Hello ChrisH,

I started building a system for lead screw control for my lathe but I have by now stopped its development.
The materials used and the point where the building is is as follows:
Motor: NEMA23 (double axle and long purchased at Arceurotrade)
Driver: tb6560 (around £10 in Amazon)
Controller: Arduino Mega (may be Arduino Uno)
Motor Power Supply: 24Volts, 6.5Amperes
Power supply for Arduino: 5Volts, 1.5Amperes

All connections are made (they are temporary) and the program on the Arduino already controls the motor.
I have tested the system with the engine running (without load) for many hours and it does not even heat up.

If you want I can make a very simple drawing of the connection diagram.

Regards
Dias Costa

I have one very similar to the one in the link I got from arc euro. I cut it down and all is fine.

My Sieg C3 (mini lathe) now uses an "oxa" QCTP also acquired from Arc Euro. The square, flat, spacer went straight into the "small bits" bin no doubt to return to dust there. Most of my tooling has 10mm x 10mm shanks Some time (years and years) ago I made a post and clamp, Norman(??) style toolpost (look in my Albums). This used an upside down parting blade, and obviously required the spindle to turn in reverse. Being a modern machine with a bolt on chuck, this caused no problems with the chuck unscrewing. Parting off with this set up was a breeze. Although parting off with the oxa is o.k. there are still knuckle whitening moments, I'm thinking of making a toolholder with an upside down blade, to try and improve things

I recently nearly finished a "chariot a vis" (Schaublin terminology) for a Schaublin 70 (again, look in my Albums). All machined on a 10 or so year old Sieg X2 mill. Gordon Bennett what a mess, but it does machine beautifully. Because my new chariot does not get used very much on the Schaublin, it occurred to me that for the small things that I make quite a lot of, The "chariot a vis" could be used on the Sieg C3 (after removing the carriage obviously). We shall see!!

cheers

For example, if the lathe were shipped direct from China to the UK, then I wouldn't expect any delay or tariff snags.

Not many people appreciate that Brexit may mean trade deals with third parties like China fail because those are actually deals between China and the EU not China and the UK…

N.

Yes that's true, I didn't mean all was well between the UK and China whatever happens next! What I meant was an order placed directly between the UK & China before March 29th would complete normally provided the shipment didn't go via Europe. To deal with that situation, the UK and EU have to agree a new arrangement.

The situation if you want to buy from China after March 29th, isn't clear either. The UK has no trade deal with China, so -at best – rather complicated WTO rules would apply until something else is sorted out.

Complicated and uncertain, which is why I suggested waiting before buying anything significant direct from China (or anywhere else!) In comparison buying from a UK supplier is much less risky.

You could just turn a reducing sleeve to fit in the 15mm hole and bore it to take 12mm or 1/2" tooling, put ahole in the side so the grub screw bears on the tool and does not crush the sleeve.

Or just make a simple 15mm dia bar drilled through for an hss toolbit and cross drilled for a grub screw to retain the bit, something like this

Both these options are standard equipment for boring and facing heads and also better quality boring heads, even those from the far east

Neil – from your post on 30/09/2016 at 12:27:20, you were looking at the ArcEuroTrade CI angle plate – which is now done by Chronos as well, – did you ever go down this route with your Adept 2 shaper?

Also, did you go down the stepper motor/drive belt to the feed handle route, and if so, could you put some details and/or piccs on here please? Would be very interested in following suite.

[Mike PooleParticipant @mikepoole82104]

A taper with a thread in the small end is for use with a drawbar which is not really needed for drilling, Arceurotrade have screw in tangs to facilitate using a taper like this in self ejecting tailstocks and the use of a tapered drift in typical drilling machine spindles. If you do not need a drawbar type taper it can probably be changed for a tang type morse taper.

I've still not progressed with this project!

I'm using a modded tyre tread depth gauge on the cross slide and a modded caliper on the saddle.

Every time I revisit this, its the cross slide that stops it!

Jim

I have a similar set up on my WM250V-F & a tread gauge on my tailstock, all work well to my needs. I was considering getting a DRO set up from EMS or M- DRO but cannot justify the expense so I stick to my tread gauges which gets me to where I need to be on final cuts. I have a remote read out system ( ArcEuro ) on my WM 16 mill which also work just fine for me.

ARC has decided to stop selling CNC machines. The key reason for this is our inability to provide back-up support, post sales, specifically for CNC machines only.

Some of you may be aware that the late John Stevenson used to provide this support for CNC machines on behalf of SIEG, via the smallcncsupport forum. After his passing away we sold a few CNC machines to customers making it clear pre-sale that it would not be possible for us to provide support. They were accepted on these terms by the buyers. However, one particular buyer was unable to get on with his KX3 machine, resulting in him causing damage to the machine. Rather than get into a blame game, we decide to accept his request of return of the machine, even though we do not agree with his reasons, and we refunded him his money.

Keeping this in mind, we are now clearing the stock we have left. The display machines have been disposed of; KX1 to Neil, KX3 to a local regular customer, and the damaged KX3 to Jason.

We have 4 x KX1s which are configured for running on MACH3, as per specifications on this page. The smallcncsupport forum is no longer supported in any way. We at ARC are unable to provide any support. First preference for sale is being given to members of this forum on a first come first served basis, subject to the conditions of no support, and subject to un-sold, at a price of £2,995.00 per machine inc.VAT + Carriage £68.26 to UK mainland only (excluding Highlands and islands – price on application). These machines come with a basic start-up manual, written by John.

Normal price for the machine would be £4,300.07 Inc.VAT. Whilst there is a saving of £1,305.07, if you are considering to purchase this machine, please keep in mind the reasons for our wanting to clear these machines, and the conditions which apply. One other reason for offering these through the forum first, is that new users may be able to get assistance from existing users of SIEG KX machines (which are not to be confused with SYIL machines).

If you are interested in making a purchase, please p.m. me in the first instance, with your contact details, and call and speak with our Ian Davidson, on or after Monday 11 February 2019.

Ketan at ARC.

The motor that you picture on the Clarke milling attachment to the C1 lathe looks identical to the motor on my X1 mill from ArcEurotrade.

Since it is unlikely that you would need to use the milling spindle and the lathe spindle at the same time I suspect that the attachment does not have a separate power controller board and that it is run from the same controller as the lathe motor. Is there a socket on the back of the C1 that the attachment plugs into?

You appear to be correct. After a little bit more research the clarke cl250 lathe has a socket in the back for the drilling attachment to plug into. My lathe is the axminster equivalent and does not have the socket. After reading the information plate on the front of the attachment I assumed the motor was AC and that is how I tested it. No wonder it wouldn't run.

I would urge you to consider making a belt drive conversion rather than replacing the gears in the mill headstock. The belt drive is much quieter, smoother and reduces any shock loading on the spindle. It is sudden shock loading that tend to upset the controller board. My belt drive conversion on the X1 mill is shown here:

http://mikesworkshop.weebly.com/mill-belt-drive-conversion.html

As an alternative motor you may be able to pick up a small dc motor that was made for an electric golf trolley. Ebay usually lists some of them. This could be used with a 12 V motor controller from Ebay

Start with a 6mm standard length jobber and go in about 40mm. then a 10mm and go in 30mm, you can then go back to the 6mm drill and cut a further 25mm. Now another 25mm with teh 10 and then start part way with say 12mm. Then if you have any blacksmith drills open up further with those.

The basic idea is that you don't go in areally long way with the drill so less chance of binding and you don't need to back the drill out as far to clear swarf.

As said collet should snap into the nut which will then pull it out of the taper when undone see this

Current spark ignition petrol engines, run at around 10:1 Compression ratios, to be efficient and to cope with the aftertreatment for low emissioins. My Aygo is Euro 6 compliant, it s 2005 MY Yaris predecessor certainly had a 10:1 C R, and was very fuel efficient!

The Air Standard Efficiency is related to the Compression Ratio; so the latter has tended to increase over the years, in the search for power and fuel efficiency.

The "Town gas" that we get nowadays is natural gas, so is probably likely to contain a butane / propane mix. What the detonation characteristics of that are, I do not know, (possibly low Octane rating?) but someone on here is sure to be conversant with the Octane or Cetane equivalence.

Also, the combustion chamber shape, and spark plug siting, will have an effect, from the point of view of ensuring the mixture being homogenous, (should be far better with a gaseous fuel than petrol ) and avoiding "end gas" which will contribute to a tendency to detonate. Detonation can be very destructive, so is to be avoided, plus the uncontrolled combustion does not improve power output or cylinder temperatures..

Not very specific as regards design, I am afraid.

Howard

Many diesel engines can be run on LPG or natural gas. They simply need some form of ignition – often a small injection of diesel fuel is sufficient. The modern petrol engine, with higher than about 9:1 will have knock detectors to alter the timing and fuel to air ratio, so I doubt this one would exceed 8:1 at the most. If designed to run on pre-RON rated fuel – the old 70 octane, or less, I would think 7:1 was likely the target, tops.

My petrol/paraffin tractors run on less than 5:1 as the kerosene/paraffin will knock under load at anything higher.

Bill double check yourself from this link

 

Note: This tool holder is not suitable for Mini-Lathes since the 4° angle raises the tool too high for these machines. Please choose the Horizontal parting tool holder 090-070-00356 for use with Mini-Lathes.

 

I'm not familiar with Seig stuff, so I don't know what defines a Mini-Lathe.

I have added a 2 axis DRO to my SC4. I'm using TouchDRO on a repurposed Amazon Kindle Fire 7" tablet, and a bluetooth interface unit built as per the instructions on the TouchDRO website:

http://www.yuriystoys.com/p/arduino-basic-dro-controller.html

You can buy ready made interface boards from the guy who developed TouchDRO as well – there are links on the website to his web store.

The scales are from arc eurotrade:

https://www.arceurotrade.co.uk/Catalogue/Measurement/Digital-Readouts-with-Dedicated-Remote-Display/Digital-Readout-Bars-with-Dedicated-Remote-Display

You just loose the remote displays and attach them to the bluetooth interface. I also added a tachometer to display the RPM of the spindle on the tablet as well.
