Thread: Lathe Speed - What am I missing out on?
16/08/2019 11:45:14

If it rings like a bell, this shows you are exciting it at a resonance and a sure indication you need to change speed. The advantage of a VFD (variable speed) is that it may only take a small change to go off resonance and hence improve surface finish.

I would hope that your <1mm would be considerably less, perhaps 40x less (I work in thous from time to time.)

Changing speed is a good idea. I'll up the speed again to the next pulley.

Also, yes it was a fraction of a mm. I didn't really measure it, as I knew it was off. I've some new (to me) measuring tools arriving over the next few days, so I'll update you once they arrive.

Good morning,

Ok, so last night i was turning ~15mm brass.

I upped the speed and I checked the center height of my single cutting tool I am using at the moment. It was very slightly high. Like <1mm high. I re-shimmed it and got it to where I think is bang on.

The result was much better, so thanks for the advice.

One thing I did notice, (I am trying to make a whistle btw, like this one Whistle pic) that once i'd bored out the tube section, it would ring like a bell when cutting, giving a very rippled effect of the cut. A bit like what you would see if you look really closely at a record. I did the remainder of the cuts with a finger pressed against the brass, dampening and reducing the ringing. The brass only protruded about 10cm from the 4jaw chuck face!

Thanks in advance.

Hi Gents,

So, This is a total newbie follow-up question I guess...

I am turning around 10mm Brass. (I'm trying to make a small whistle, spinning top, etc etc.) all with some small stock to get in some practice.

From the posts above, and from what I can find online, I should be turning at >2000+ rpm?

Is that correct? I'm still a little nervous about spinning my lathe that fast, and have mostly been using it at around 200-300 rpm for similar work, with horrible results. I get a crappy finish, often the thinner the brass stock can bend quite visibly instead of being cut, and it can make a nasty grinding noise.

I have carbide tools, and have the extra sharp mirror looking inserts, which work great on alu at around 300-400 rpm. (Although that was thicker ~30mm alu stock!)

All this cutting speed stuff is very new to me, and I'm starting to think that my previous efforts were a lot more luck than skill. ha!

Thanks in advance.


Thread: Myford Super7 Chuck and Tool Holder points
13/08/2019 16:38:02

Hello again Gentlemen!

So I have spent some time getting my lathe setup and true. Without going on too much, there are 2 main questions I have: (plus some bonus sub-questions!)

1) Myford sell a 100mm small bore and a 125mm big bore 3 Jaw for the Super7. Both can be supplier fitted with a Small Bore super7 backplate of 1&1/8x12tpi.

On the Myford website, it states in the 125mm chuck (without backplate) listing that the 125mm chuck is NOT SUITABLE FOR 2MT (small bore) lathes as it is too heavy.

I called Myford. They said it is fine, and that loads of people have that fitted. On this forum, there are multiple threads discussing this, but with no real conclusion. Myford assure me it is fine, and that there will be no excessive wear after many years use. Has anyone heard / experienced the contrary?

1.a) Bonus Q: Can you think of any reason why I would be better off with the 100mm vs the 125mm? For the extra £25ish, I think it's worth being able to hold slightly larger parts. (Although the majority of my work is going to be at least for the time being, smaller parts.)

1.b) Bonus Q2: The Pratt Bernard chucks by Myford get a LOT of praise. However, many people discuss/voice opinions that cast iron is more flexible than steel and various other arguments. The PB chucks are around £220ish. RDG sell HBM and other makes for ~£70 ish for comparable sizes. Are they to be avoided given the choice?? Why would you buy a PB today for almost 3x the price? Are they really that much better generally speaking.

2) Lathe tooling. Due to the access I have to a Warco lathe, I already purchased a bunch of 12mm tools over the year before getting my S7. The S7 has a 4-way toolpost, which only works with an 8mm tool plus a ~1.2mm shim.

Myford advised me to buy the ML10 ONLY toolpost as the toolholders are more adjustable and can take a12mm tool. Has anyone done this? Is it workable / practical / sturdy? (Thicker tools vs ?thinner? tool holder) Ideally I dont want to have to re-buy a full set of tools as it's about the same price as a quick-change toolpost which brings all it's own advantages .

Everybody is stating to get a Quick-change toolpost, both on multiple threads here and elsewhere. Additionally, on here, none of the threads on S7 tool sizes mentioned being able to quite easily be able to use a 12mm tool...! Is this a new development?

Lastly, there is lots of conflicting information on Myfords website, and Ebay, forums etc. I'm looking for proven facts people on here may know, as I am not sure what information to go on from online. (Also, many of the tools/gauges etc use stock images of other tools, so often even the images aren't a reliable source of info!!) Everything I've been told by one of the very helpful gents at Myford seems to make sense, I am just curious if anyone else has done the same as what I am planning. (125mm PB 3Jaw, and QC ML10 toolpost on my S7 to hold 12mm tools.)

That is about all. Thanks in advance!

Many thanks.

Thread: Cleaning and preparing a new to me, old lathe

Posted by roy entwistle on 31/07/2019 15:58:55:

Just don't forget that what look like grease nipples on a Myford are for oil not grease


Very good point yep. I've been cleaning each of them as I work around the lathe. Hoping to have it purring quietly very soon.

31/07/2019 15:44:13

So, I didnt want to hijack this thread: #Cleaning a new lathe# so thought i'd make a fresh one.

I'm almost set to start playing with my new to me 1950s lathe, and wanted to check what level you guys do a strip down / clean up / grease up etc, before starting to do any work.

I've given the drip tray a complete wash with typical fairy, to remove the grime from the last owner, however, most of the machine has a light oily coating on it, and the bed seems to have a suitable film of oil on it too.

I was just wondering if I should clear all the old oil/grease/cack off the machine and then do my own lubrication with fresh oil/greases/etc, or if that is a bad idea.

Many thanks in advance.


Thread: My New Project... Setting up my new Myford Super7 Mk1
31/07/2019 14:43:59

Progress so far...

In Its New Home



I connected up the electrics last night, and will be putting on the drive belts tonight!!

One questions I do have is that I think the vendor swapped out a chuck before it was sold. The chuck seems to have a lot of wiggle when tightened on a piece of bar, and also, it seems to have a high/low spot between the backplate and the chuck, causing it to wobble when it rotates.

The Chuck backplate is hard up against the mount. I checked the mount and it turns true, so the problem is between the backplate and the chuck. I'll do some more investigation tonight. I am taking a lot of hints from this thread...
##This Thread##

Hoping I can see if I can resolve it sooner rather than later.

31/07/2019 14:30:54

Managed to upload some pics...







Now it's in my living room and i'm reassembling it.

31/07/2019 12:05:36

So as you may have seen, I purchased a Myford Super7 Mk1 last weekend, in Wales, and imported it to Ireland where I live.

This was done in my tiny little Ford Fiesta, which handled the Lathe and extras very well, after an admirable packing job.

Now the lathe is home, (in an albeit temporary location in my living room) and it needs setting up to make it true and usable. (It also doesn't help that I left a bag of bits with the vendor!!!)

Anyway, I'll be uploading some photos of the lathe at the vendors, then the journey home, and setup and where it's at now...

Image post coming up shortly...

Thread: Buying a Lathe, as always the age old questions...
30/07/2019 10:28:33

Hello all,

After all you advice on assessing the lathe, and packing/moving it, I am now the very proud owner of a Myford Super7 Mk1, from 1957. It's beautiful. I will post some photos when I get them onto my PC.

The lathe was bought in Wales, and I imported it to Ireland, where it is now (temporarially) located in my living room, until my ManShed is complete. The Irish weather isn't ideal to take off the roof etc, but I'm hoping i'll get it complete over the coming months.

I managed to fit the lathe, stand, drip tray, multiple tools and fittings, etc all into a 2005 Ford Fiesta, along with 2 people! Cosy, but it worked.

Thanks again for all the advice and help. I am very pleased to now be part of the Myford family!!


Thread: Stuart 10 V casting
30/07/2019 10:23:25

Thinking about it, I had very similar on mine also. (Stuart 10V Kit from castings)

I actually didn't go all the way through to it was uniform, I just polished each of the surfaces. I didn't realise it was a difference in the metal structure.

Engine runs ok however, so

Hi Del,

Yes we intend to go DCC, at the moment we have around 200 locos / DMU's about a 1/3 are DCC fitted, and the rest will be fitted as time progresses.


That sounds awesome. I only have 4 but all are DCC, However, my layout is only big enough for 3 of them.

I hope the progress is coming along nicely.


Thread: Buying a Lathe, as always the age old questions...
25/07/2019 16:18:15

Gents, thanks again for all your fantastic advice. I am going to view a few lathes this weekend, and hopefully return home with one in the back of the car! From what I've measured, it will fit, but could be tight. ha.

I'll keep you posted, and send in some pictures if i find a suitable one. I've also managed to get some help from an uncle who happens to live nearby where the lathes are being sold, and has spent decades building model steam engines, so that is also a huge relief too.

I'll be taking onboard all your advice, and doing loads of tests and see the lathes spinning etc. Thanks again for all your help.

Fingers crossed my first ever lathe is not a complete wreck!

Wow, that definitely looks like an awesome project.

I've a tiny 009 layout, which is also on its end atm.

Am I right in assuming you are going to be going digital with that quantity of track?

Best of luck with it. I'm definitely interested in seeing pictures as you progress with it.

Hello Olivia,

I am new also. Welcome to the group.

Thread: Buying a Lathe, as always the age old questions...
22/07/2019 17:27:18

Hello again,

These are absolutely fantastic pointers and a huge help. Thanks again. I have received a several images from the owner, and would be happy to post if these would give any extra insight.

It looks like a lovely, well maintained machine but as you say, that may not be the best information to go on.

I'll print out the points you have mentioned above and take them with me so I do not miss anything.

@Martin and @Dave, thanks for your very detailed posts. Definitely covered way more than I ever considered, so will be of a lot of use.

I also called Myford and spoke with a very friendly and helpful gent there who advised me of a few pointers too.


  • Hold the chuck and try to shake/wiggle it. There should be no movement.
  • Use a DTI and rotate the chuck and it should run true.
  • As you mentioned above, try wiggle the cross-slide/saddle. Again, expect no movement.
  • Check for noise etc when turning on/off, grinding, whining, etc, as you mentioned.
  • Check the bed - Move the saddle the full length of the beds in both directions. Should be smooth and consistent along the whole length.

The points you chaps have given is hugely valuable and may end up saving me a fortune.

I'm open to more information too if you think of anything else. Quite excited to see it in the flesh.

I'd also read somewhere that it is strongly advisable to remove the lathe from the cabinet when transporting it. Apparently they are very prone to wanting to fall over which can be terminal!! Would there be any key transportation tips assuming all is well with the lathe? (Not that I'm going there guaranteeing to bring it home, but I am hopeful it is as nice as it looks, and dont want to have to make 2 journeys if it don' have to!)

Thanks again,

.......but make sure that you give ANY future used machine tool a thorough inspection and observe it under power. There are others on here who can advise you much more on this issue.



Hi Derek,

Please could you expand on this point you mentioned. Are you talking about the lathe as a whole under load, or are you talking about the tools/cutters?

Please could you also include a method/concept for the testing. I didn't really understand.


Lastly, does your lathe have the embossed Super7 logo in the belt lid, or does it have a plaque?


Kindest regards,

Its good. I used one in my tech school, so was very familiar with it. Everybody seems to talk about Myford though. I was at the model engineer event in London around xmas, and most of the demos were on other (probably eastern made) lathes, but most of the stalls sold mostly Myford parts.

I'm not looking for a vintage piece of kit, but I like the look of the Myfords, and they seem well respected in the UK. As mentioned above, they seem to get a slating in the USA. I've no idea why.

I've also a very small shed where I plan do locate the lathe. The Mrs wants it out the house with all my other tools. I'm still working on that bit though!
