Thread: I knew it was coming...
29/09/2011 09:15:19
BBC World now talking about 'remote controlled airplanes' and 'GPS control' and appear to have dropped the photo's of the nice F-4 and F-86 (or Fury?) models in their live coverage ( at leats in the article on tv two minutes ago.
Thread: MEW 182 - Wot no ...
29/09/2011 09:07:10
But a very promising start to a beginners series ... looking forward to using this to move on from my current scrap making activities. I am hoping that this will include some practical exercises and a method for getting feedback/tuition (maybe using this website?).
 
Maybe I should write I letter of encouragement?
 
BTW - No point in suggesting local schools/clubs etc ... I live in the French Alps, cows and ski's only round here (and some very hi-tech manufacturing in semiconductor and nanotech - bit small even for model engineers).
Thread: Rust and how to remove it.
22/07/2011 12:30:57
Interesting topic. Typically I have used the battery charger/electrolysis method for derusting which has been very successful on old woodworking tools and a somewhat mistreated drill chuck (teenage son left it out in the rain for weeks!).
 
Some points :-
 
1. I found electrolysis is SLOW (hours/days, not minutes) larger the lump, longer the time, but effective, and while there may be some pitting where the rust has been, there is no loss of metal otherwise.
 
2. Thoroughly dry and coat the item (I use WD40) as soon as you take it out of the bath. The surface is now very, very clean (i.e. no protection AT ALL) and prone to corrosion.
 
3. Dispose of the residual gunk carefully, rumour has it that it can contain some nasties (such as chrome) .

Thread: Model Engineer Reader's Survey
10/06/2011 08:51:47
JasonB's suggestion works great, just make sure the scan file sizes are not too large or David's email will reject them without sending an error message back to you (made that mistake!) .

Thread: The SURVEY !!

Thanks for the update David - The wonders of modern technology. I will check when I get back home.

Since I am part of the international readership I scanned and emailed mine to David over the weekend. I would be interested in knowing if that worked for David since the scanned files were quite large. It worked for me .

Thread: Late delivery of magazines due to adverse weather
24/12/2010 12:45:34
MEW 172 Just arrived  here in France (in the Alps) it's currenlty snowing hard, so as long as they are not on strike La Poste gets the job done!
 
Bon Noel a tous!

Thread: tutorials for CAD?
05/11/2010 12:38:09
I don't know about CNC, but Dassault have recently released their 2D CAD package as freeware and the manual seems pretty good for learning. There are also many videos on their community support site.
 
Worth a look maybe?

Thread: G-Code in a downloadable form
20/06/2010 11:40:55
Hi Folks,

I am old enough to remember typing in listings to my ZX-80 from the computer hobby mags at the time. Took a long time, then you had to debug to find the typing errors, then you had to debug to find the logic errors (and that was without the risk of physically destroying things that machine robotics/CNC can do) As soon as it became feasible magazines moved to electronic distribution (on cover disk, CD, etc ....)
 
Using printed listings in my opinion has all the issues above, plus this wastes valuable magazine space better used for words and photo's when internet distribution is so much more efficient ( and cheaper!). I would think that anyone running CNC machinery would have at least a low bandwidth internet connection capable of transferring a few K of text files about.
 
BTW OCR depends on very high quality scans and a good portion of luck, not one for the MEW digital archive then ...
 
Just my opinion.

Thread: Filing Machine Construction

Hi Folks,
 
Went to the MEW digital archive and there is MEW 4 - with the article - but NO plan ... did I miss something or are the free plans not included in the digital archive?

Thread: Navigation buttons to older digital MEWs missing
18/05/2010 08:49:45
Looks like these have been moved to the MEW digital archive section rather than the paper subscribers section. It would have been nice to have had some warning at least. Thankfully I have a subscription to both since I am on the middle of reading some of the earlier (recent) issues.

Thread: Choice of small milling machine
03/05/2010 18:30:00
Did a quick check of the backlash by locking the table.
 
X direction ( Left and Right ) = 0.15mm or 3 divisions on the handwheel
Y direction (back and forward) = 0.1mm or 2 divisions on the handwheel
 
Both directions are a little "sticky" but then the shipping "grease" has yet to be cleaned off and it has the consistency of a mild glue.In either case this seems a little excessive to me but OK for the moment since my machining skills are nil anyway.
 
As for the z (vertical) axis since this has a DRO fitted it seems pretty accurate once I had figured out how to engage the fine feed.

Hi Hansrudolf,
 
I have a DTI and your instructions are clear. I will be in the workshop during the week since I am working from home this week so I will give it a go.

Latest Update:
 
WM-14 is now out of the crate and on the bench, It has been plugged in and runs, and all displays light up and the knobs work. The next step will be to open Milling-A Complete Course and get to work making some T-nuts etc.
 
Hans Rudolf asked "Please check lead and backlash of the spindles, and are all the same?" If someone is willing to tell me how to do that, I will have a go.
 
Next question  : as an engineer (semiconductor NOT mechanical - hence lots of questions)  I am used to writing reports, but I don't see a venue for posting documents ( e.g. several pages of A4) on this site - anybody know if the webmaster has any plans?

Hi Hansrudolf,
 
I hope to document in some form my adventures in this new hobby, although it may take a while given I have still to work to pay for it! Yes, I have the famous test report with a lot of check boxes and 7 measurements...

Good Evening Folks,
 
Update on my previous post. GEFCO delivered two crates this morning so I am now the proud owner of a Warco Lathe (280V) (Built Jan 2010) and the new WM-14 mill (built Dec 2009)  among other bits.
 
Unfortunately I could only get the crates into the workshop before close of play today ( An 18 year old son costs a fortune in food, but provides a decent amount of muscle when needed) and I am working in Geneva for the rest of the week so I can't start the preparation work until next weekend .

Anyway - the toys look good in their crates, well protected and coated in some form of sticky protective grease/oil ( the famous 'chicken fat' perhaps ) with no obvious damage. Once I get them out of the crates I will have a better idea what to do next...
 
Progress is being made.

Good Morning everyone, glad to see this thread reactivated, I have followed with interest since I subscribed to ME at christmas.
 
Point 1 - I am a very raw beginner working in metal (I am a semiconductor engineer now working on manufacturing software systems) - and this is only my second posting...
 
Point 2 - Warco service : I ordered the WM-14 before christmas, and the kind salesperson rejected that idea - she suggested I waited until the new model, which was much better! The new model is due here end of March with a bunch of other kit ( good for me, I live in tha Alps and have just finished the workshop, and the snow should have cleared from my level by then so the truck can maybe get to the workshop door). I think that Warco service have been excellent so far with prompt responses, good advice (as far as I can tell - see above)  and clear communications, but maybe could be a little more proactive?
 
Point 3 :I have also found the Workshop series of books an invaluable reference especially the Lathework and Milling complete course ones. Made me a lot more confident about selecting machines and I am now desperate to start cutting metal, and making some of the tooling projects in those books.
 
I was a bit downhearted by previous comments in this thread, but more recent updates have restored confidence. I will let you know how I get on when the new toys arrive.
 
BTW I type on a French keyboard, and can't spell anyway so apologies in advance.
 
Dave

Good Afternoon webmaster, sorry to report.
 
"The page cannot be found" error for Model Engineer 3536 Part 2 - the last part of the parting off article ...
