Thread: How to tram a mill
16/09/2011 13:06:37
Hi John,
 
Firstly, I wouldn't use a drill chuck, they are generally not accurate enough A collet directly in the quill, or a collet chuck would be preferable.

take a look at this there is some useful info here on tramming a mill.
 
cheers

Thread: Quorn Castings
16/09/2011 13:00:51
Spoken to Mr Law today, they are still waiting for 'complete' sets of castings to be supplied from the foundry.
Once they have sufficient stock to supply their expected demand (which from talking to him would seem quite a significant amount), they will then publish the new website.
 
I am hoping to get in touch with Mr Law's son by email shortly as he will be running the business and website going forward.
 
As soon as I know more, I will update this thread.
 
The biggest problem they are up against is getting the foundry to produce full sets of castings, as he quite rightly states, its no use havin 14 out of a set of 15 castings equired to build the Quorn!
 
regards

I guess part 3 may have the rest of the info we are looking for as part 2 ends in 'to be continued'
It would be useful to know which 'chinese' lathe this is aimed at.
Thread: Proof reading, what proof reading ?

You could say the same about photos 3,4,5 and 6 on pages 294-295. We all know what a part looks like in a chuck, these photos add absolutoely nothing to the article and are simply padding.
It's all well having pretty colour photos in an article but they must add value and show something that is of use in the construction etc.

Thread: Digital Issues
27/08/2011 22:30:12
I see now that all of the archive of both ME and MEW are now using the new digital reader.
I also note that we still do not have the long awaited (and promised) printing facility.
Also note that despite ME 4011 being available for several days now, this issue is still not available as a digital issue.
There have been many requests from subscribers, for these issues to be resolved.
Why is it that no-one seems to know who is responsible?
Why do MHS staff not respond to their advertised email address?
MHS surely must be in breach of advertising standards or something similar as they are clearly not giving access to the latest issue as soon as published, as ponted out by Steambuff.
I wonder just how long this thread will continue before someone at MHS finally take some responsibility for the abysmal services the purport to provide.

Hi, this is how my GH thomas bending rolls are geared, the top roller has about 20mm of movement whilst remaining meshed with the idler gear
Thread: Removing Clarkson chuck
24/08/2011 17:08:24
I had a similar problem removing a morse taper from an old mill some years ago. The quill was first treated to a liberal dose of a release agent, left to soak in over a day or so. I loosened the drawbar a couple of turns and applied an impact drill in the non rotating setting (i.e impact only) this was sufficient over several minutes to free off the taper.
 
This is preferable to whacking the drawbar with a large hammer as the effect on the bearings is minimised, although there is no guarantee that the bearings will not need replacing.

Thread: Old Oxygen Bottles Use
23/08/2011 10:59:30
Compressed gas cylinders are generally rented from the gas supplier such as BOC or Air Products. Invariably they will not refill a bottle which is not registered with them.
 
I use Adams Gas for my Mig Argon bottles, they do not charge bottle rental, their range includes hobby gas bottles which are reasonably priced.

Thread: Turning
18/08/2011 13:25:36
Hi,
The miniLathe will cope with these diameters however, you are dealing with very slender components which by their very nature are very susceptible to longtitudinal distortion.
 
Can you provide drawings for this component and also describe its intended final application. What grade of brass is to be used, what are the tolerances on the final dimensions etc.
 
regards

Hi John
I will see if I can get the print icon on 179 removed for consistency.
PDFs are not down to me.
I am still waiting to be told who is in charge of digital issues.
regards David
 
WHAT!!
 
This is surely a Mis-understanding!
We WANT the print facilities on all digital issues, removing it from the only magazine that it actually works on would merely exacerbate the situation.
 
Why is it so difficult to contact those who are responsible for digital issues.
I emailed Ben Rayment who is listed as being the Web Editor however I have to date not received a reply. I probably should not be surprised considering...

David, can you tel us who IS responsible for the digital issues and who we contact to raise a complaint. It's no good syaing 'take it up with the management' if we do not have a point of contact.
 
thanks

Thread: Don't assume the obvious

Having worked as a technical author for many years in military service, one of the principles we adhered to was to preceed any abreviations with a fully worded description.
i.e Cold Rolled Mild Steel (CRMS), or Cast Iron (CI).
Once the abreviation had been described, it could then be used througout the document without ambiguity.
Materiels such as Lead (PB) or Phosphor Bronze (PBn) which has differing grades, depending on the compositrion, are more difficult to differenciate and should be clearly identified.
Thread: New technology in Model Engineers Workshop

When is somebody going to take the time to fix this forum so that the adverts do not overlap the text in the posts. It should not matter what is posted in the text, that should not have any effect on the formatting of the forum.
If this is a long term problem then the publishers should be considering changing the software application used to provision the forum. After all, the facilities provided are pretty basic compared to other ME forums on the web.
Thread: Wrong cover page for 4409

If I used excuses like that my Boss would use my privates as Xmas decorations!! I work in a service industry where customer satisfaction comes before sleep and holiday!!
We pay for this service, Holidays and sleep aside, this is a very un-professional approach to a paid for service.
I was contemplating ditching the paper subscription in favour of the digital but I can see that this is a long way off being a viable proposition.
The digital issue was supposed to be being upgraded to a new reader, yet that also seems to be fraught with difficulties.
When is MyHobbyStore going to get its act together and actually produce something which is stable and commercially viable.
All we get is unsubstanciated excuses for failure to provide a reliable service. When will this all end?????
Thread: Hammerte paint
26/07/2011 17:10:17
Cellulose will most defintely react with hammerite (from experience!).
If you want a good finish in a workshop type grey, then I would stip the hammerite and paint with a gloss oil based paint. I have been experimenting with various makes and have found Wikinsons own brand non drip to produce acceptable results with a brush on application. It also seems so far to be resistant to any of the products used n the workshop. The paint I used was marked as suitable for wood or metal, the also sell a red oxide primer for undercoating any bare metal first.
Thread: ME 4407 - New Viewer

When in zoome mode, the scroll wheel changes the zoom level, but when in normal paging mode it does nothing

Just a minor observation, with the old viewer, it was possible to flick through the pages using the mouse scroll wheel, this doesn't work in the new viewer. Would be nice if this could be implemented in the new one, that said, the new viewer is a huge improvement and a lot faster. Looking forward to the whole archive being converted.

Thread: Rust and how to remove it.
19/07/2011 18:04:59
Well, after several attempts with the caustic soda/electrolytic method (and very little success), I decided to give the Hydrochloric acid method a go. Quick trip to the local builders yard, parted wit £6 for 5 Litres of high strength brick cleaner and I have, in an afternoon, de-rusted an old 12" 4 jaw chuck which I acquired some time ago. One of the jaws has freed up so a little more soaking in the HCl and I think I may have rescued a doorstop.
 
BTW, this stuff absolutely stinks, make sure you use it outside or in a well ventilated area.
I'm going out tomorrow to buy another 5L and a bigger container so I can get the whole chuck immersed. I'll let you all know what the results are, (wish I'd taken a before pic now).
 
The solution I bought is 18% HCl and seems to be very effective with no dilution.

Thread: The perfect ME Lathe
18/07/2011 18:22:47
Many of the chinese lathes are getting very close to an ideal machine, build quality aside!
DRO's are nice but not a necessity, I have been aking accurate parts for years without one on my lathes. Accurate dials and a reasonable brain work just as well.
Camlock mounting is essential, the screw on chucks of Myford et al are dated and potentially dangerous.
Geared head with a 2 stage belt drive to extend the range gives the majority of speeds required by most model engineering disciplines, maybe a belt change system akin to the tri-leva system would be a distinct advantage.
 
A quick release clutch and a single point dog clutch on the feed screw are essential.
 
Geared head lathes are not necessarily noisy, or inconducive to a domestic environment.
My Warco GH lathe is very quiet, ( in fact I often work late at night and none of my neighbours have heard any unduly disturbing noises) well, not form the lathe anyway LOL.
 
To compete with far eastern manufacturing will be very difficult in the current economic climate.
 
For a quarter of the cost of a top end Myford, I bought a large capacity machine which met most of my requirements. Whatever is missing can be easily manufactured for very little financial outlay and will still surpass the capabilities of a Myford.
 
Don't get me wrong, I grew up with Myfords and have recently acquired an ML7 with a Tri-Leva selector. This will be a refurb project although mostly cosmetic, as there is no detectable wear on any of the critical components.
 
As the drawings and rights to design for the Myford lathe have now been bought out, I would suspect we will see far eastern clones appearing in the near future at a lower price, albeit with possibly a lesser attention to detail and quality.
 
We can all dream of the ultimate machine but that will attract the ultimate price.
 
I dream of a DSG or a Monarch 10ee but I doubt if I will ever own one, so I will continue to buy what I can afford and modify to suit.

Thread: Soft Faced Hammer
16/07/2011 00:02:36
It all depends on what you are hitting with the ommer and what results you intend to achieve.
My 'Soft' faces have a variety of heads, all produced in the workshop, which vay from lead (very soft), thru copper, brass, Delrin, Nylon, etc.
It all depends on what you want your ommer to achieve
 
A little more info on what you are using the ommer for will assist in advising suitable materiels.
