Thread: Stringer EW lathe
18/07/2017 16:05:11

Ian. thanks for your reply, at least I hav'nt been asleep for the past half century. Very interesting as you say I look foreward to more info.



18/07/2017 10:26:36

hello all.

Can anybody give a purpose for the lugs an the headstock castings, front. of Justin's lathe, in 65 years of EW interest this is a first for me.



Thread: Tooling for Centec2 mill
15/07/2017 17:36:15

Hi Sean, Don't be discouraged by adverse comment. I am a centec nut and would promote the brand

The lack of a vertical head did not stop me making 2 steam loco's both 3.5 gauge on a centec model pre the series 2.

The use of morse taper holders in the horizontal arbor hole was my starting point. I found the application of a hammer to release the taper distressful and made the holders with a threaded nose, with a nut to draw the collet out when changing the cutter, I would fully recommend this design.

A centec 2 obtained some years latter inherited the collets that are used in the horizontal arbor and a vertical head I made some time later. You do not need to starve to save money for buying the centec Vertical head.

I have taken some photo's that may help you but am having problems loading them. Have fun with the centec.


Thread: Bandsaw Blade Flash welder help needed please...
27/04/2017 12:10:18

Hello, I have an even older version of the" Ideal" unit, also saved from the scrapyard. This saving was one of the best such actions I have made, it is a very usable and useful addition to my workshop.

I found a company -VOLLMER UK LTD , Town st. Sandiacre, Nottingham NG10 5BP. that were very helpful and moved my project in the right direction, they did send me some documentation but not giving the sort of detail you require. If you still have no luck with what you want, I could copy my stuff to you.

Please do not let this bandsaw butt welding machine stuff interrupt the very interesting ELS log.

regards Paul.

Thread: dividing head /indexing
18/11/2016 16:26:54

John, you have been busy. The cutter speed is 150 RPM. I today ordered a 6oo P/R encoder described as AB two

phase. The stepper will be driven by one of your "cheap as chips" TB6600 2/4 phase hybrid motor driver.

Your outline is very encouraging.

regards Paul.

18/11/2016 15:18:32

Muzzer, thanks for response. The use of the device is to provide input to stepper driver, what John Haine described as, cheap as chips.

The only schematic I have is from the MEW article. I'm not sure of the protocol of posting it here, I could E-Mail

a copy if you leave me a message with your address.


18/11/2016 14:02:34

Muzzer, thanks for your posting. The 80's , oh yes I remember them well (cue for a song).

I expected things to have moved on in the world of electronics since 2005 and the circuit function requirement is simple. My ability in this area is monkey see monkey do.

Your suggested replacement is noted thanks. How about 2N7000?

regards Paul.

18/11/2016 12:57:52

John, many many thanks for a most helpful and informative posting.

Your comment on the VN10 is spot on, the purpose of its inclusion was lack of output to the stepper driver when

Brian Thompson first built. the unit.

The explanation of PLL you gave is most enlightening and produces an alternative for the one part of the project that raised concern in my mind. The concept is clear to me but I lack the know how to set up the circuitry.

One of Steve Wards objectives in his divider design was for a self contained small unit and that is what I wanted with the hobbing device.

thanks for your help. Paul.

17/11/2016 12:11:36

John S. Thanks for your posting and direction. The thread is interesting in part because it answers a question

raised when I read recently that your black box failed and you went Linux way. Now I know the story.

Again many thanks.


17/11/2016 11:09:03

John, thanks for your reply. I must again agree that Steve Ward contributed greatly with his design, and help he gave to others trying to build it.

The article by Brian Thompson was in MEW no.108 Aug 2005. The ic's -HEF4059, VN10LM, are the problem units.

Your comment on encoder and alternative is very interesting and timely as I'm at the procurement stage for this section of the unit. I am not familiar with, phase locked loop, but if it simplifies the project i'd like to be.

Mark Smith, my interest in the electronic approach is because I built the mechanical set up and quickly tired of the

set up times when the unit was applied for 1 off hobby use.

Regards Paul.

Since electronics will last about 5 years before going phut that will give you time to make a proper mechanical replacement.......

hello, If 5 years is the working time forecast, that will be long after I go phut and if not could still be long after me.

regards Paul

As this is 2016, I suggest you consider using a stepper motor to drive the worm driven by one of Mike (?) Ward's excellent controllers. Then you don't need to worry about division plates, prime factors, and all that stuff, just type in how many divisions you want and away you go. JS' approach using a commercial gearbox would be quick. Ihave converted a Myford DH and wouldn't consider going back to plates'n'oles.

+1 to this thinking, so much so that the Brian Thompson article in MEW" gear hobbing without change gears" is for me the next step. Problem, the IC's are now marked as obsolete. Any electronic wiz out there have any comment?

I'm sure John, you remembered Steve Ward.

Thanks Paul.

Thread: 5 speed toothed belt drives
21/10/2012 13:25:00

John A.S.

I have a centec 2a which has the same boby and drives as the 2B. I also suffered the same warming up experience as you describe. I came to the conclusion that the primary (motor to machine ) belt and the machine gears plus the lub oils caused the slow speed up particularly in winter when the motor cut out could be activated.

My solution was the fitting a seperate motor for the vertical head using a poly vee belt plus an inverter, I have not looked back. See my post under newton tesler title last year.

Regards Paul.

Thread: Clarkson Stirling Single 3.5"
05/05/2012 15:43:50


The boiler on Clarksons 3.5" stirling does as Bruce suggested need to be locally "adjusted".

I found this as being required when I built my Stirling but the minimum side play on the drive axle makes the adjustment required small,

Good luck on the build it is a most rewarding model to drive.


Thread: volkswagon engine

Roy, PM sent . Thanks

While riffling through old model engineer mags, as one does in the chilly evenings, I came across the above titled article by Brian Perkins. and was struck by the possability of this as a project (for me).

Although I thought I had a complete set of issues for the past 35 years I have been unable to find part 3 of the description for this article. The ME date for the article was April1, 2005.

Could anybody provide a scan of the model volkswagon article please?

Many thanks

John, I have at last managed to load my photo's.

 the photo also shows the lifting block which is the extended overarm. This allows
use of the machine in horizontal mode without taking off the very heavy vertical head
as previously mentioned a satisfying mod.

Hello, I have fitted an inverter to my centec 2. The method I used was to mount a seperate motor to the head. This has resulted in a very controlable quiet machine
\also fitted to machine is an extended overarm which gives the machine a bigger
I have taken some photo's but have not been able to load them, sorry.
The process for loading the photo's on the site is very poor in my opinion.
Thread: centec 2b
10/12/2010 15:29:40
hello Duncan,  I think the 2B head is the same as the 2A.  If this is the case then the fast feed lever is mounted on the spindle by the nut and a taper.  You cannot remove the spindle as the other end to the lever ,is fitted with a key and the slow feed wormwheel.  that is to say you can remove it but will loose  the control of the head downfeed!
Regards Paul.
Thread: Stringer EW lathe
08/12/2010 10:50:49
hello from nippy berkshire,
I have owned an EW lathe for the past 60 years and enjoyed its possession. It was a
toolmakers design with many interesting features.
In 1957 and 58 a number of mods and articles appeared in ME by the hand of Martin cleeve, it would be worth your while getting hold of these.
One item not covered ( in my recollection) is a clutch in the drive chain. I made such a
fitting for my machine, it is without a doubt an absolute must , making for a much greater
enjoyment  when using the machine . I must admit to an obsession with regard to the
fitment of a clutch on ALL lathes (is that a shout?).
