Hi Sonic.

Something like the 1st picture would be your best bet IMO. I've two different ones which both seem ok for the job.

You don't say for which lathe.

The one Arc Euro Trade sells i find works best in the mini lathe as the blade is a little thinner than others i've seen~ which is kinder on the mini lathes limited power & rigidity.

Regarding parting off on mini lathe, a few tips.

1 ~ never have blade sticking out more than is necessary for the job in hand.~I broke my first blade recently on 10mm silver steel,because i was too lazy to wind it back in after a bigger job .

That made me jump! Blade shattered, good job i had my safety specs on.

2~ make sure the blade is dead square to the work.

3~ plenty of lube if parting off steel.

4~ slow steady cross slide feed & i find around 250-300 rpm works best for me.

5~ lock off everything you can (except the cross slide obviously)

Often, needle roller bearings have an outer cage and run direct on the shaft itself.

It looks a s if the original cage has broken up.

If you measure the individual rollers, adimater and length, and count them, quoting the shaft diameter , a bearing supplier might be able to identify the bearing.

Arc Euro have a limited range of Metric nedle rollers, but will, I am sure be helpful.

Probably googling needle roller bearings will bring up a good range, but it looks as if you need to talk to a supplier.

Hi everyone,

OK, I have come to a decision. It's been a day of lots of conversations and to-ing and fro-ing. I have been overwhelmed by the helpfulness of Ian at Arceurotrade but the long and short is, I am reverting back to my original 4-post tool holder.

The QCTP has defeated me and being honest, my abilities are not sufficient enough to make a stud (or even Jason's suggestion of a shouldered nut). Kind offers from you gentlemen have humbled me, but realistically, I don't use the lathe enough yet to warrant going to all the effort to get one made.

Thank you all for your support and effort. It's been quite a weekend of broken screws, drilling, tapping and generally messing about with something which I had hoped would be an easy conversion.

But that's it, in a nutshell. It's not the end of the world. It's a learning curve and I may revisit this in the future if I find I am using the lathe more and more.

Again, thank you all.

I have just asked my brother to measure the distance from the top of the top slide to the centre of the workpiece/chuck – it is 20mm.

Does that help in anyway? Looking at arceuro's spec, I can't make head nor tail of which QCTP is the correct one for this!

[Margaret TrelawnyParticipant @margarettrelawny34058]

Hello chaps,

sorry for my late responses but I am at work.

I am awaiting responses from arceuro and Amadeal.

Jason – putting the tool in and offering up to a workpiece looks fine – although I did have to adjust the tool holder up a little (not sure if this is normal practice as i have nothing to compare against) – but a standard tool of the size I generally use does reach the work piece ok. See pics. Although I am concerned how far I have had to adjust it. There doesn’t seem to be much thread left on the adjuster- is this normal?

I will try the stud later when home tonight but it looks likely that the stud will work or worst case, I need a new stud. The threads on the original stud look a bit worn don’t they?

i’ll send dimensions of the stud later when home and reply to all the pm’s.

thanks all

Hello Duncan – thanks for the link to Coventry Model Engineers. I will bear them in mind. I bought the 250-000 from arceurotrade – and although the post has been taken out of the bag, it hasn’t been used. Some oil has leaked off the parts onto the cardbord packaging – but I noticed the boxes for the holders already had oil stains on anyway.

It seems though I have made another mistake in buying too small QCTP. Because the swing over is 12cm, I should have purchased a 250-111. So I am hoping to exchange it.

Malcolm – thanks will try your suggestions first.

[Margaret TrelawnyParticipant @margarettrelawny34058]

Hi Howard,

Thanks for your suggestions. I have definitely bitten off more than I can chew, and the disappointing part is that it all looked such a simple swap on the YouTube and ArcEuro videos I watched. Had I known what I was letting myself in for, I wouldn't have attempted it. I am near Coventry.

Unfortunately, the shaft cap and larger diameter part of the original stud is larger than the newer threaded stud.

Stud cap: 15.18mm

Knurled part of stud shaft: 10.37

Fatter part of stud shaft: 10mm

New stud thread: 7.5mm

All the best

Hi all,

No need for anyone to feel bad. It is part of my learning curve – proving to be costly and a headache but I guess that's how we learn.

Update: Everything is now apart – thanks Jason for your suggestion and input. I heated the ring a little and tapped it and again, it came apart.

I just need to find a way now to get those damaged screws out – otherwise that part is scrap.

For the toolpost stud, I just don't know what to do. I am not sufficiently experienced to make my own (as I am sure a lot of you guys are able to) nor do I have the tapping equipment etc. I have emailed both Amadeal and Arceuro to see if they can help. It seems the CJ0623b is slightly larger than a mini-lathe. I have nothing to compare so I don't know.

It's such a headache.

Thanks again for all your input and help, it is very much appreciated.

[Margaret TrelawnyParticipant @margarettrelawny34058]

Hi Noel, thanks for the reply. I took your advice and added a little heat and gave it a small tap and it popped out. Yey!

But now I find the two posts are different! The one in the kit is threaded both ends – have I purchased the wrong kit from arceuro? The one on my lathe is a push in fit, the kit one threaded. (My lathe is an Amadeal CJ0623b if that helps?). The videos I watched on ebay it was a straight swap!

Also, I have identified the little pin which seems to be stopping the circular part from moving. How can I remove this please?

I am at my wits end! I wish I hadn't bothered and stuck with the 4-way tool post.

Thanks all

Margaret

Hi Jonti,

Welcome to the forum. ARC sell spares – including motors and controllers – for their machines, may be you could find something suitable there. IIRC the smallest motor is 150w (for the C0 or C1), next is 250W (for the C2). These are brushed DC motors. The SC2 has a brushless 500W DC motor, may be larger than you need.

If you can find the code for the inserts, there will be several possible UK sources, as well those to be found on the web.

Even the dimensions will help to identify.

Arc Euro, J B Cutting Tools, RDG, Chronos immediately spring to mind, plus probably our other usual machine tool importers

[Andy StopfordParticipant @andystopford50521]

Well, I've got to disagree with the 4-way enthusiasts here.

I think a QCTP transforms using a lathe. Yes, the holders a fairly expensive, but you don't have to buy loads at once, you don't have to fool around with shims, just a simple screw height adjustment to set each tool up, you can take a toolholder out, noting the setting on your dials, put in another one and use that, then swap back to the original and know that the dial setting is still good (yes, I know that a 4-way should index properly, but on a cheap lathe it probably won't, and the indexing mechanism only works with the toolpost and topslide aligned – no setting the topslide round to clear the tailstock)

Also, it takes up less room than one of those four way abominations with its tools sprouting out in inconvenient directions ready to take a chunk out of your hand when you're trying to mic the workpiece (and you can hardly ever use all four positions with a sensible combination of tools).

I have one of these:

https://www.arceurotrade.co.uk/Catalogue/Machines-Accessories/Lathe-Accessories/Tool-Posts/Model-000-Quick-Change-Tool-Post-Set

It would have probably been better to have the next size up, but I re-used it from another lathe and I don't have any problems with the rigidity of it – parting off diameter is only limited by the lack of low speed torque of the brush motor on my lathe, and the maximum depth (15mm) of the carbide insert toolholder I usually use – I have gone considerably deeper in stainless steel with a blade type holder, but I worry about cooking the motor with such antics. Of course you have to have the holder set accurately to centre height, but that's easy with a Quick Change toolholder…

[Howard LewisParticipant @howardlewis46836]

Ball and Radius cutting.

Any device which allows a tool to be rotated about the axis of the lathe can be used for ball or radius turning.

Arc Euro sell such attachments for the lathes that they sell.

You could even make one yourself. Might be an interesting and informative exercise.

And money saving for a tool that is likely to be unused for a lot of the time.

Having been left a small legacy, I bought a Repton Radius Turner, from Chronos. It will cut up to 60 mm, and given my limited useage, am satisfied with it.

[DMBParticipant @dmb]

'orses for courses' I use a QCTP system for light – ish work but my OEM Myford toolpost is always handy for a quick swap to thicker section tools, be it HSS or brazed tip carbides. Always heavier option for iron castings e.g., loco wheels. Centre height adjustment with Myford oem clamp is quick and easy if you store each tool with its appropriate packing, like I do. Beware!

I bought a cheapie QCTP system many years ago from a toolstand at an exhibition and a few holders. When I later wanted more, he had discontinued them. His punishment is strict avoidance of that dodgy trader. My go – to for tools is Arceuro and a limited number of regular advertisers. Big items, only buy big brands.

[not done it yetParticipant @notdoneityet]

Rigidity is always a potential problem with QCTP on a small lathe – extra points and overhang to contend with.

Arceuro is my go-to supplier of all things for lathe/mill. They get most of my trade.

Another option is to make an identical 4-way toolpost and swap as necessary. OK, I never had more than three cutters installed, but a home-made copy could be cheap and reasonably effective as an alternative.

[Ches Green UKParticipant @chesgreenuk]

Margaret,

Thanks for putting me on to 'Mr Ade Swash' …. he has a very good YT channel.

As for QCTPs, I use ArcEuroTrade ones – they are adequate enough for my skill level…. https://www.arceurotrade.co.uk/Catalogue/Machines-Accessories/Lathes/SIEG-C3-SC2-SC3-Mini-Lathes/C3-SC2-SC3-Accessories/C3-Quick-Change-Tool-Post-Set …. I have an Arc supplied Sieg SC2 lathe.

Arc do a wide range of QCTPs… https://www.arceurotrade.co.uk/Catalogue/Machines-Accessories/Lathe-Accessories/Tool-Posts

That seems small, M8. ARC Euro sells M10 and 3/8" BSW ones for MT2 tools.

Otherwise, if the spindle or tailstock barrel is clear right through use a drawbar instead.

I tend to use the centre in an extension sleeve to give myself a bit of room and thought it'd be nice to be able to drift it out nice n easy…

[JasonBModerator @jasonb]

As you don't have the 9/16" cutter and say you are unlikely to use it again I would the boring bar option

Spot drill then drill say 6mm, 10mm and 12mm or whatever you have and then use a boring bar to bore a flat bottomed hole that can be tweaked to get the fit you want on your tube.

Buffer –

"Bah Humbug!" There you are: quoted it again for you. Chas. D. has a lot to answer for!

The foods are literally a matter of taste of course, but you don't need watch the telly.

Nor do you need listen to Radio One (though these days Slade is probably Radio Two): try Three or Four. The former does celebrate the religious aspect of this mix of old Christian and pagan turn-of-year festivals, with such broadcasts as the Nine Lessons & Carols, and the EBU's European tour of live, mainly church, music.

I do agree though about the supermarket's nonsense, the Christmas stuff interrupted briefly by the horrible pseudo-Hallowe'en rubbish imported from the United States of Disney. It is usually possible to avoid the busiest times though.

I have long had round-robins from two couples. One is just a bland "look-what-we-and-our-[now grown-up]- children-have done" designed to make the recipient feel inadequate. When I learnt MS 'Access' I was tempted to create as an exercise, a database designed to create such letters as Reports from drop-down menus!

The other couple though is quite different. Similar family history but much less self-conscious and with lots of humour. Not only that, but the letter's A4 sheet is folded to form an A6-size "card", illustrated with a church identified by its name and town, drawn by the husband. He is a retired architectural-historian, so hand-drawing buildings was part of his professional skill. So although the same card to all, it is one made with a lot of personal thought and care.

Oh – and my grand-nephews and nieces do thank me – but these are young children! We adults don't exchange presents beyond immediate-sibling level (four of us).

.

My Christmas Day In the First Year of the Plague was the first I'd ever spent alone! Very pleasant too. An hour or so in the workshop, then chatting in the sunshine to my neighbour over the garden wall. A leisurely nominal Christmas Dinner with chicken (our family always had chicken not turkey, and anyway it's goose in English rather than US tradition) and a µ-wave Christmas Pud. Lazy afternoon with a bottle of beer, and the calm, non-patronising friendliness of BBC Radio Three. (No TV? I have no TV!)

.

Dave –

Cards to verify existence? Oh dear!

Most of mine are not family ones despite ours being quite extended by now, but to and from friends; and total around thirty. I can hand-deliver two batches, in my two caving-clubs. One is based 300 miles away in Yorkshire, but its Annual Dinner in November is a convenient opportunity for card-exchanging.

I never feel them a waste of time but I have reduced humorous cards relevant in some way to the intended recipient. Not sense of humour failure, but they are more expensive than "ordinary" cards. I am an RNLI "Supporter" though use some of that charity's cards, especially those illustrated with Giles cartoons!

Tricky one is a card to one of my nephews. He's probably secular, from our largely non-religious family with Anglican background, but he's married a Muslim. What to wish them?

Welcome.

Although not a Hobbymat user, the advice to fit and machine a backplate to suit a 4 jaw chuck is sound.

With a little care it can be done.

I think that backplates for Unimats are available , (Arc Euro offer 14 x 1 ones ). For a machine with the older 12 x1 thread, it will be necessary to bore out the 14 x 1, oversize, before making and fitting a 12 x 1 bush ("Heat and Freeze" technique ).

The backplate can then be fitted to the lathe to be faced and a register turned to suit the new 4 jaw.

(I have just machined and fitted a backplate, in this way, so that a very old lathe, (Possibly 1920s / 30s,with a 3/4 BSW thread ) can use a currently available 4 jaw chuck, for someone else ).

Hi everybody

I have joined this forum on the advice from arceurotrade who are a very helpful bunch of guys.

Just a little about me. Retired when I was 60 (2016). Hobbies are motorcycling and motorcycle restoration of 70's/80's/90's bikes, kit model aircraft building (WW1) and generally anything that keeps my mind active!

I own a standard HOBBYMAT MD 65 lathe and it is this that I wish to ask about. It's fitted with the standard 80 mm three jaw chuck which has been fine for making small and hard to find motorcycle parts as I've only needed to use round bar or tubing. However, I need to fit a four jaw chuck to take square section material. There are plenty of four jaw chucks available but, according to arceurotrade, they will not fit on to the chuck flange of the Hobbymat lathe.

Has anyone been able to sort the problem of changing from three jaw to four for this lathe and, if so, how?

Thanks for reading my ramble and I hope someone can help!

Ta, Andrew.
