You could soon polish the flywheel up with emery cloth Brian. Maybe with a drop of oil to help stop it clogging up.

You'll probably need an extension drill for the grub screw hole. There are 2 ways of doing that. Face, centre drill some 1/4 dia mild steel, drill a hole and then loctite the drill in in it. Or use a pin chuck to hold the drill and fit that in the machine's chuck. These might need tightening with pliers.

When you figure out how to hold the flywheel at an angle don't angle it any more than you need because the drill will be inclined to skid on the surface. A centre punch mark at the angle the wheel is at will help but I'd be inclined to mark the surface with say a 1/4" dia drill as well before using the one for the tapped hole.

Holding it at an angle?? Saw the angle through a piece of wood leaving 2 pieces at the correct angle and clamp between those. Tilt the table if it will do that but the vice will need clamping that way.

A flexible drill vice is handy. I have one bought a long time ago that was made in India. It's similar to this one

Arc also do another range that is cheaper but they look to have gone pointlessly over the top with shapes machined into the jaws. All that is really needed is a ledge for plate, a horizontal V and a vertical one. People have used the one I have for milling and drilling things like lock plates. Ideally they should open to a bit more than the jaw width. Rotagrip sold an identical one but seem to have changed designs now. Oz – there are some similar one's on ebay including by Optimum. Also some SG Iron ones.

Just had a PHONE CALL from Arc Euro. Apparently I hit a known problem with browser history. If you hit the problem I did refresh the page. This forces the browser to not use an out of date copy it has kept. On Firefox (and I think other browsers) pressing F5 does this.

Full marks to them for following up the problem and I hope this helps others to continue to use the Arc Euro site.

The smaller of me 2 lathes [Warco GH750 ] is powered by a Siemens 3 phase motor, and a Eurotherm Drive [Now made by Parker SSD ] the set up is now around 15 years old and has, and still is, working perfectly. Motor and Drive were supplied by Transwave.

In practice which often differs from theory, something like plus two thou to minus 10 but the more you get undersize the more rock there is.

There is no collet system that will please all but the ER's are fast becoming a good gap filler in both work holding and tool holding and there are bridges to accept both like this 5C to ER from ARC.

050-070-00800 5C to ER32 Collet Adaptor

One often quoted advantage of 5C over ER's is you can get square and hex collets in certain sizes, but as long as you are not ripping 10mm off at a time Jason has prooved that ER's will also hold square and hex of any size that fits in the range.

If the vertical read head has died, a replacement won't break the bank, few places sell them, but Machine DRO do:

Neil,

If the z axis fine feed reading head is totally dead, depending on the age of his machine, the part to which you have linked 'may or may not' fit his machine, provided he can figure it out and not drop/lose bits during the dismantling of the assembly.

That reading head has gone through a little change over time. The assembly is part SX3-29 which is currently to be found on this page.

As you can see, the buttons are a little different. It is not possible to say if the fittings inside are same as the machine-dro link you gave Simon.

I did not direct Simon to the link because his post indicated that he had his dealer HAFCO servicing his requirements in Australia. Also, if he is not sure about what he is doing, parts can fall out during dismantling, and then one ends up trying to help the person to sort out his problem…as we know from experience in the U.K., and not something ARC wishes to get involved with over this distance. If Simon decides to consider your proposal or the assembly SX-29 as shown on ARCs site, he would need to consider 'the risk' he is taking, and make his own judgement call,….or deal with his dealer in Australia.

That's helpful, John. I was thinking of buying the ArcEuroTrade set of ER16 metric collets, I take the advice about the imperial size.

I too have had excellent customer service from Arc Euro. They also went to a great deal of trouble giving information about some reversing switches (Seig spare parts.) which I had suggested as a suitable spare on a non Seig lathe. I can totaly understand the policy of not giving any warranty on electronic components as they can be destroyed in microseconds if connected incorrectly or to other faulty parts. Even If Arc had a X3 in stock (Which they probably do not as it has been replaced by the SX3) I would not expect them to rip a machine appart to test your board with the possibility of it damaging other items in the machine and the time taken.

Les.

Thanks Les..as it so happens, we still do have an old X3 which we use for a variety of testing. Without getting into details, it has helped us in many ways, to include certain destruction tests.

That's the first really clear explanation I've seen of why a 63 (or 21) tooth gear works so well, as a driver, for metric conversion.

Arc Euro Trade updating website

—————————————-

We are going through the process of updating our website.

As a result of the change from the old to the new, visitors may find that certain pages look as if they are 'work in progress'.

The new site is expected to be launched by middle of next week. Once launched, there will still be some 'work in progress', as we fill certain departments with correct pictures and information.

The whole process is expected to be completed by the end of this month.

If anyone in the U.K. finds difficulties placing orders through our site during this period, please call us and we will be happy to take orders over the phone.

For reasons of security, all overseas customers are still requested to place orders through our website. If the ordering process becomes difficult, please email us and we will try to assist.

It is our hope that the disruption to service will be minimal, and we would like to apologise for any inconvenience as we go through the changeover.

If you grind up a tool something like this and don't go in too deep with the Ctr drill you can turn quiet small diameters, this is 4mm but I have gone down to 3/32"quite happily. BS0 drill and a small radius on teh end of the tool otherwise you risk your "V" shaped tool acting like a threading tool. You can also buy half centres that have a flat on the side to give extra tool clearance though I've never had the need to resort to one

If you are going to be using this test bar more than once then a reduced dia at the ends is not a bad thing as it will protect the finished dia from dameage if you drop the bar so you could have a short length of say 8mm dia at each end which would take a small dog.

Definitely easier, and remarkably economical

… I wonder why Crawfords went to all the trouble of grinding a thread inside

Hi Graham,
Here is a slightly modified version of a diagram I drew for another thread ("do i need reverse" 09/04/15)

The reversing switch was bought from Arc Eurotrade and NVR can be bought from Arc Eurotrade or from ebay.

If you mount the capacitor on the motor you will need another piece of connector block in the motor connection box.
I am adding your picture to this post so it is easier to read in future.

Hi guys, I'm after a little bit of advise please.

I bought an ER32 collet set some months ago for my mill, and thought it would be good to use them in the lathe also (Myford ML7)

I bought a 4" collet chuck and blank back plate from Arc Euro, and I've machined a shoulder on the back plate to be a tight fit on the recess in the back of the chuck. I then used a transfer punch to mark the through holes in the back plate. This is all bolted together with 3 M8 socket cap bolts.

Now, when I put a dial indicator against the flat area behind the collet nut, it's true to less that 1thou, but, when I fit a collet and some ground rod (silver steel) it is out by 15+ thou!!

So my question is, how accurate are collets? I assumed they would be almost spot on every time. Should I machine the shoulder on the back plate smaller by 5-10thou and the set the dial on the ground bar stock and tap the chuck till it's true and then nip up the M8 back plate bolts?

Thanks for any advise, cheers, Rob

My illness happened after I was sacked from ME and MEW. I always had sufficient articles purely because l asked for more even though I did not need them straight away. I alway put the best articles in first that I had which meant some were delayed. I also talked to people to generate required articles.

I learnt my engineering from Model Engineer in the 1960s in the school library. I went on to earn a £1000 a week in engineering from reading Model Engineer.

Tooling does have a place in ME as does the basics of CNC. Nothing has ever been too advanced for ME in the past.

I think Model Engineer has lost its way slightly. I tried to get away from the every other issue syndrome and tried to put articles in consecutive issues. This encourages readers to buy every issue to get a series and also to subscribe.

Many readers like to get all parts of a series before they start construction.

 

MEW is finally improving. The last 3 issues have had interesting article(s) in them. I always think that a magazine is worth reading if I learn something from it.

MEW has to run multiple part articles as you will never get enough short articles.

I did occasionally send articles to Ketan for checking if it concerned an Arc Euro Trade product and Ketan also gave me universal bearing numbers.

I did not see anything wrong with this.

If Diane knows nothing about CNC and prefers to leave the article as written I am sure Neil could give it a look over for obvious mistakes before printing it.

Finally to all beginners: no question is stupid if you don't know the answer. Ask away, you will not look foolish. I still ask stupid questions if I don't know the answer.

My ER25 set is 35mm af and the machined portion is 42.5mm long plus a thread 17.5mm long thread if that helps, agree wholeheartedly regarding their usefulness.

You can however get parallel shank ER chucks for £15 or so from Arc euro which can then be held in your blocks. `I see they also do ER40 blocks too.

I think Warco charge a fair bit more for what appear to be the same brushes.

The new ARC brushes arrived today, fitted straight in.

Happy days.

A big thanks for the heads up on this.
