There is a previous, fairly comprehensive thread for the Chester DB8. This is the older one, 6 Spd not the V later version with a longer timing belt.

Our timing belt has disintegrated, it needs a M1.5x z118 x15

Chester don't have them any more, ArcEuro Trade, have shorter and longer but not this one. Has any one found these belts? Or managed to find an alternative that works? Or modified their DB8 to a different set of pulleys or different system?

Any thoughts or pointers will be much appreciated, thanks Richard

My first QCTP was of the piston type. I found, like Bo'sun, that the toolholders didn't fit very well and would even work loose while in use. I eventually fixed this problem by making new pistons, but was never really happy with it. I replaced it with a wedge-type from Arc See here. I have found it to be far superior to the previous type, just be sure you get the right size. I went for the smaller 250-000 size for my Asian 9×20 clone lathe and that is more than adequate for my needs. Additional toolholders also seem to have a consistently good fit, too. There are a number of forum members who run the same lathe as you and will be able give specific guidance. You'll pay a bit more, perhaps, but in my opinion, the extra outlay is well worth it.

Thanks for the feedback. I was aware of the Warco one but had heard they weren't great quality.

I was thinking about something like this and machining a new stud. I'm also not sure of the advantages of the wedge type or the piston type.

I guess I'm not sure what is out there and if there's anything that requires minimal modification to work.

[Thor 🇳🇴Participant @thor]

Hi Steven,

Welcome to the forum. Warco sells several different QCTP's, have you asked them? On my 290 lathe I use this QCTP, a friend got a good price many years ago. I have made some extra toolholders.

As for taps the ones I reach for the most are spiral flute, YG-1 for models and ARC for general work, jigs etc You really only need one of these not the usual set of three and they can be turned by hand not just machine.

You should measure the runout at the inside of the spindle taper. If that is not possible, then on the outside of the chuck taper.

As per Huub, above, measure the taper runout. A commercial blank 2MT arbor would suffice, for this.

ONE OF THESE

That’s the first thing I did, with a MT2 test bar and also a MT2 jacobs taper adapter, and it’s the same. 0.003.

Thanks for replies. I should have said that when I noticed the effect I checked the spigots for witness marks showing where the chuck had gripped. They were there, and the jaws had gripped the spigot at (eyeball accuracy!) 60° to the depressed areas, so the front faces of the jaws were behind the 'raised' areas. That observation got incorporated in my thinking about the cause and was implicit in my speculative explanation, but I should have mentioned it explicitly. Sorry!

If I have understood the axial deflection explanation correctly the pattern should be the other way round if it is right.

The discs were faced using a fresh 0.4mm radius CCGT insert (Arc Euro Trade), so sharp(ish). Roughing cut ~0.5mm, finishing cut ~0.05mm. So very little axial cutting force for the finishing cut I would have thought?

I take old mart's point that it might have been better to make the hole last – sequencing of machining operations is an aspect of this hobby I find particularly challenging. I guess it comes with experience – I didn't anticipate this effect so no amount of planning would have helped. The reason for the steely appearance is that I had to adjust lighting to display the contrast between the areas, and that must have mucked up the colours on my phone camera.

Anyone out there with a finite element analysis program? Well above my pension grade, but it would be interesting to see the stress field for work held in this way.

usually the keyway is 1/4 the diameter of the shaft so a 2mm broach will do nicely, ARC as Rod says do them at a reasonable price. Available separately here

If you look at some of the posts over the last few weeks in the Princess Royal thread lots of talk about keyways, and keys.

I broach my flywheels to match the angle of the gib head keys, plain milled slot in the shafts and not had one fall off yet out of about 25 done that way. No grub screws used either. Before getting some broaches I planed my keyways with the lathe moving the carriage in and out with a 1thou cut per pass, tilt the flywheel in the chuck or pack on the faceplate to get the seat angle.

Arc do a 2 and 3mm broaching set **LINK**

You would have to make a bushing to suite. The alternative is to slot the flywheel with a topslide slotting gizmo. A lever action one is easiest but for a very small key then just winding the topslide would do, if somewhat tedious.

[Richard GibsonParticipant @richardgibson42431]

A really useful thread but are still yet to find an appropriate belt for the Chester DB8 (not the DB8VS), pretty sure the belt would be a M1.5 x Z118 x15 ( though the pulley would take a 19mm width belt. we have spoken to Chester, we bought a M1.5 xz124 x15 from ArcEuroTrade, too long but right pitch and have spoken to them.

Has anyone found one of these belts or found another that fits? Or has anyone modified their DB8 to take a different belt?

Any thoughts, much appreciated. Richard

[JasonBModerator @jasonb]

Yes the smaller "backbone" of the 3mm broach should allow you to mill a slot for that and another to take a 3mm key at 90degrees so you can index the bush and get the two keyways in the flywheel at 90deg.

If you did want a bit more key then you could go for a rectangular 4 x 3mm one in a 3mm slot, It's just a case of adding an extra shim which you can make yourself but two 3×3 keys will be plenty strong enough when compared to the original grub screw and no keys..

Uncle Ketan's site has an article on broaching

Hi Chris. In response to your specific question, yes I have fitted this system to my Myford. It works very well indeed.

There was a minor tweak required to remove, if I remember correctly, some material from the foot of the tool post supplied with the kit to allow it to fit in the recess in the base of the compound slide.

Arc Euro holds stock of the appropriate tool holders. This has been important to me as I have added tooling which required additional holders.

No connection with anyone, just a satisfied user.

Peter.

[Martin KyteParticipant @martinkyte99762]

Thats a lot of faff for a screwdriver slot, I have 3 knife files invarious sizes and just file mine. They look very good and are tapered to suit the blade of the screwdriver so the heads don't get chewed so easily in use.

Example of files here

Hi All,

Arceuro wedge type probably a lot cheaper than the Dickson type.

I purchased an el cheapo Dickson clone from a local ME supplier at Guildford club's open day many years ago. Unfortunately I didn't buy enough holders and several years later wanted more but said supplier discontinued them. They worked OK, happy with purchase and still using them. Here's the big but! Upon buying more holders elsewhere, new ones don't quite fit. Could never understand why until careful measurement revealed reason. Solution given by article in a recent copy of MEW, dismantle toolpost and shave a bit off the back of the puller that grips the toolholder. An easier solution for others; buy a complete system from one of the better suppliers and get plenty of holders at the same time.

[Graham StoppaniParticipant @grahamstoppani46499]

I bought one of these from ArcEurotrade. In my experience this wedge type tool post is far superior to the Dixon type that came with my lathe.

With my old Dixon type toolpost, even after tightening everything up as far as I dare, the tool would invariably dip down slightly when cutting the work piece because of the amount of play between the tool holder and the tool post. I took my Dixon tool post and holders to a show and compared it to the ones on sale that were no better fit.

The wedge type tool post by its design takes up the slack between the tool holder and the tool post and now the tip of the tool does not budge when cutting the work piece.

As you say, you will need the adaptor. Please note that a tiny bit of facing off may be required to have the adaptor seat properly. This is not because the adaptor is faulty but, according to ArcEurotrade, there are slight variations in ML7 that need to be accommodated. It took me just a couple of minutes to measure and face off to the correct size.

The tool post is notably smaller than the Dixon type on the Myford but more than up to the job, even in my clumsy hands. My only regret is not getting it sooner.

[Chris MurphyParticipant @chrismurphy94983]

Hi all,

I think I quite fancy going for the arceurotrade Model 000 Quick Change Tool Post Set, which I’ve had my eye on for a while now, it’s £109, but you have to buy a kit to make it fit my Myford ml7.

the question is, has anyone fitted this to their Myford ml7 and if they have could you tell me what it’s like to use.

id like to know a bit more about it before shelling out the money just in case It doesn’t fit or if it’s not very good.

any info would be appreciated.

thanks

Welcome!

You have done well to find data on what looks to be the Chester equivalent.

Since yours is painted red, it may well be a Sieg. In which case, it may be that Ketan Swali at Arc Euro Trade might be able to provide more information.

Looking at your pictures, to my mind in addition to a set of Change GHears, you will need:

A banjo, c/w with clamp This will clamp around the bush through which the leadscerew protrudes. It will have a slot to take the

Stud/ s (C/w clamping ) for intermediate gears

As anewcomer. it would be a good idea to buy some books to read up using a lathe and a milling machine.

I'll PM you with a list. Look for a flashing envelope near to the top left hand corner of your screen, next to SETTINGS

What does all this mean?

CE asserts the item meets European standards.

FCC is the US Federal Communications Commission, and an FCC certificate means the item conforms to US emissions requirements. Industry Canada (IC) is like the FCC, and I think they issue certificates too.

Shock horror, the device isn't marked with a UKCA mark! UKCA marks aren't quite as rare as hen's teeth because I've seen one! (Only one. Are Brexiteers happy with that? Two and a half years after finally leaving the EU, we're still using CE marks. Write to your MP!)

Legal frequencies for radio microphones in the UK listed here. The channels used by Ian's microphones are listed in Orange, meaning they're available but are Short Term PMSE License Required – Date & Venue Specific. I guess Ofcom check the microphone frequencies don't interfere with TV in the area. So not illegal if you have a licence.

Channel 70, 1.9GHz and 2.4GHz don't require a licence. 1.9GHz is shared with DECT phones and 2.4GHz with Bluetooth and Wifi.

Hmmm. I have not yet found a video that can actually help me learn anything! I have learnt from videos what others have done, but that's not the same thing.

My "block" with CAD is not a "block" with computers generally, as you think; but you are probably right I will never learn to use CAD, at least not to a very useful level.

I did not touch a computer until c.1990 when a change of work brought me face-to-face with them. One of my first training-courses there was an Introduction to MS-DOS! Followed by others over the next few years on MS 'Windows, 'Word' and 'Excel.

The last was very much part of my work, for collating test result while swearing at Mr. Gates for not knowing 360º = 0º, nor giving decent axis-annotating routines, on polar graphs he called 'Radar Charts'. (We typically used 3º increments, and 'Excel' seemed to think we wanted every angle value labelled.) I still occasionally use Excel, mainly for model-engineering calculations.

I had also picked up a modicum of BASIC thanks to local programmes on laboratory computers driving electronic analysers; and developed this a bit further on my first own computer, the Amstrad PCW9512 on which I also wrote the mss for a cavers' guide-book. (Though primarily a word-processor, with its own printer too, the Amstrad came with compilers for BASIC and very strange language called DR LOGO – which did fox me.)

.

So my block is not of computers per se but of specific applications; but part of a much broader aspect, that of my natural limits to learning anything.

My models, if I ever finish them, will never be of Model-Engineering Exhibition quality – I'd be lucky to pick up "Commended". There are huge expanses of the subterranean world I would love to have visited with my caving friends, but too difficult for me even when I was younger and fitter. Early dreams of a science or engineering profession were impossible because I cannot learn mathematics beyond a very low level; although my entire working life was at shop and lab floor level in these fields. I do not have the memory for foreign languages. When I gained an A-level in Geology in evening-classes some years ago, fellow geology-society member brightly asked me about taking an OU Degree in the subject, but that would have been beyond me.

'

I have a theory others more qualified than I refute but not convincingly, that aptitude is not only highly individual but rather like a bucket. Think of a row of buckets on a beach; each its own size, labelled with a practical, academic, sports, artistic, etc. subject. Start filling each bucket with water: once it is full any extra water just overflows into the sand. You cannot extend the bucket, so it will never hold more than its original volume.

If this were not so, why is every Sunday League footballer not being head-hunted by Manchester United; every pub-pianist not performing Rachmaninov or Beethoven at the Proms; everyone who knows the difference between power and energy not progressing to designing power-stations or managing CERN… and so on?

'

If I stall with learning TurboCAD beyond what I have managed so far; or SolidEdge at all, it is not because they are CAD systems or even just on computers, at all.

It is because I have reached my physical capacity with those particular skills!

It is my understanding that payment for articles comes from the Advertising budget. It is obvious that people who took multi page adverts in the past, – Euro, Warco, Axminster, no longer do so and it looks like Home and Workshop machinery,have also stopped. This causes the re-use of previously published work. If you submit an article ,it can take more than a year to appear, so ther cannot be a shortage of articles in the pipeline.

Evri: A new name to me so I have looked it up.

Hermes: started in West Germany in 1972.

Expanded to several European countries including in 2000, the UK, and now has its HQ in Leeds.

Created the myHermes brand in 2009, dropped it in 2018.

Re-named itself as Evri in March 2022.

Owner: private-equity company, Advent.

The Hermes ParcelShops notice on my local branch of the Co-op's "NISA" is still Hermes, but it will take a while to change them all having followed the business fad for pointlessly changing a company or brand name from explanatory or at least arcane, but familiar, to merely meaningless!).

I wonder how many people who are caught by this type of fraud, are genuinely expecting a parcel; rather than reacting blindly to merely being told one is on its way.

[HopperParticipant @hopper]

The Myford ML7 Users Manual that is available free on the net as a PDF if you google it, contains a good section on a simple way to set your lathe to turn parallel by "twisting" the bed using shims under the feet at the tailstock end. (This is for turning without a tailstock centre in use of course, as SOD described above.) You do it by turning a test piece of scrap bar and measuring it with a standard micrometer. So no fancy levels, dial indicators, test bars etc needed.

As far as a general "how to" book, Neil Wyatt's book from ArcEurotrade would be more relevant to your modern Warco than the classic texts by Sparey et al. that are more Myford oriented.

I think you will find that the Clarke CL300 is the same machine listed as SC2 in the Arc Euro machine spares. That's where I have got bits for my CL300 in the past. ( I am currently in the process of converting to a 3 phase inverter + 1/2 HP motor combination from Newton Tesla, having given up with the original control arrangements)
