Thread: What type of STEEL?
05/03/2010 19:16:22
So true Hansrudolf, given the power of T'internet, it just shows how lazy some can be. There are so many conversion tables out there for anything you could wish for, but for the sake of pushing one or two buttons. At least YOU are trying. Lay some time aside to have a look down this list :-
 
 
 I have another one on another which gives a comparison between the old and new designations, It may even give Werkstoff No's , will have a search.
 
  Regards  Ian.

One thing you COULD try Alan is posting on :-
 
 
 With the best will in the world, getting info from third parties twice removed really confuses the issue.
 
  One reason for using a sparkie in toy boats was that they were slow revving but had bags of TORQUE so the howl of a glow type hadn't been invented. The "Oscillations" syndrome was usually induced in toy Diesels by trying to run too rich so you got a sloppy sound when flicking over with a naked finger.
 
  As you're "Wimping out" () by using a starter, this is hard to believe that it's "Four Stroking".
 
  Keep taking the pills.

Thread: Oil Traps
01/03/2010 13:16:12
Basically Fred, an oil trap is a can with an inlet and an outlet. The exhaust steam and crud goes in and the oil drops out allowing "Clean" steam to exit and up a chimney. Make sure the inlet from the engine points downwards so you don't get a "Blow through" effect. When he designed it, I don't think Basil?? thought about "The Enviroment", he was just trying to get people re-interested in steam propulsion.

Thread: Drawing projection, first or third?

One thing to watch if anyone does go down the Alibre road is that the first upgrade from free allows you to use a 3D and auto 2D converter that was previously free for a "Limited" (30 day) trial period. After that, an "Offer" price is introduced.
 
  When I first tried it, the Dollar rate was nearly 2 to the pound so as the American site was offering $99 for the intro price, the British arm offered at £99. When I challenged this, I was given the robbing out of the vendors kids mouths tale but they would reduce it to a lower figure although it still didn't meet the American figure and mumbled about VAT charges.
 
  Sadly (For the British arm) many purchased via paypal and the American site and got a good deal. So be warned. Where this, and many others, profit is from the extras and tutorial packages that cost whatever more.

Although it sounds like the "Proffesionals" ganging up Neil, Corel draw really is a POS when it comes to drawing anything else other than Graphics.
 
  Before the howls, I used to have severe arguments with SWTSMBO who regarded Lotus123 as a do anything programme from accounts to letter writing etc. A BIT like "Works". NO, it's an accountancy based programme which does extra bits, but NOT a sectively dedicated "Fits all" suite.
 
 Go back to post No. (Oh sorry, we still haven't got that one sorted yet David) re A/Cad being the generic tool, and yes it was and probably still is a b***h to master, but is STILL the industry standard, but like everything else, if Proffesionals need to talk to each other and interchange technical info without fear of data conflict, their employers will pay whatever to get the latest "Release" or issue or whatever AutoDesk now call it and CHARGE for it.
 
  All the spinoffs have had the "Edges" softened to try to make their own versions more user friendly and each have their own band of loyal followers who claim whichever is the best.  OK. to put this in easy terms, which CAR is the best???????
 
 While I have "Slagged off" Corel Draw, if you're happy using it, why not?? There is no "One size fits all", so one of the problems with generating a league table is who do you ellect to generate it?? Although I was taught how to use A/C and having both Release and Year issues of it, an extended lapse of use would create a long blip in picking it up again ALTHOUGH after downloading a free (Has to be) issue of DoubleCad (successors to TurboCad), it became obvious "who" the daddy programme was.
 
 To illustrate the way various programmes suit different users, a mate who is a non professional in engineering terms was quite happy to use Corel and had difficulty using A/Cad changed over to "Alibre" recently and found it a "Dream" to use as opposed to A/Cad and wondered why he's been fooling with Corel for so long? A free trial version was the decider but he has gone on to buy the official version. I tried Alibre and can't be bothered fooling with the 3D INITIAL layout proceedure.
 
   Get whatever you can as a free trial and see how the water suits you, BUT make sure, as we've already said, Make sure ANYONE can read and understand what you've drawn.

Thread: Elbow Engine
27/02/2010 10:54:24
Yes Jason, but on OTHER fori, the designers have sorted the website so that long urls are folded to suit a frame width.
 
  Used to have the problem with overlarge photos dissapearing over the edge (Still do on THIS site) and creating Looooooooooooong one liners. This by the way is one of the sites you post on and THEY seem to have fixed the problem.
 
 As it seems to be a CONSTANT bone of contention, you would think the owners would take steps to have the frame width fixed. Perhaps not, take it or whatever.

Surprised you're letting this one go Anthony as after DROs everyone seems to dash out and buy a collet set of far eastern origin and then start to compare notes due to their varying degrees of (in)accuracy and then wish they could get a "Propper" original set.
 
  Usually more accurate than chucks for bar turning and repetition.

Thread: Drawing projection, first or third?
26/02/2010 14:50:32
Yes Steve, and I'll bet the designer had done one or two mould designs before?? How was he at laying out a Printed circuit board from the electronic circuit?? You have to compare apples with apples, so you are agreeing with my earlier statement on understanding the product. My PCB designs were manufactured in the UK, but my moldings were sourced from Taiwan, and although I had left mold design behind, only one of my moldings ever need a "sliding core" and that was for a product security feature only.
 
  Where it leaves you Peter is covered in the last three lines of my previous text. Draw it how you like, as long as the target can understand it. Another variable you have drawn into the discussion is which drawing Programme (Program for the collonials) you use. Although ALL the systems are derivatives from AutoCAD, to make them more user friendly, they all have their little quirks and have been generated to allow the non professional user a method of putting straight and square pitched lines on a "Paper" space. Pity the originators didn't all use an interchangable compatible system of generating the drawings. One thing the electronic generation method HAS changed is the need not to have to draw to "Scale" IE. 2 :1 or 1 : 500 or the likes. Full size is Full size no matter how big or small the finished item is, so Davids point on lines and text smooths this out.
 
 
    Ramon, you REALLY should chill out.
 
  Regards  Ian.
26/02/2010 10:47:14
Firstly Ramon, despite having a lifelong career in "Full size" engineering starting in the toolroom and through my own efforts traversing via the D/O to works management, I would ALWAYS describe myself as a "Muddle Ingineer", so I would never try to insult anyone who has a more normal type day job and then chooses to impregnate their fingers with sharp bits of metal.
 
  One for Steve, ever worked with  "Contract Draughtsmen"???? One of the problems in working in any "new" firm is finding the different working standards and manufacturing capabilities. My own training "Spoiled" me by dropping me in with "Old Ingineers" (Thank heavens) but the range of equipment for cleaving bits of metal was second to none, so having the grounding of HOW to cleave and WHAT to cleave with stood me in good stead to enable me to progress to "Design" tools, tooling and later components for both mechanical and electro/electronic product manufacture.I doubt that any of todays "Kids" could emulate that route in manufacturing cos the BASIC grounding is not there anymore.
 
  The problems I found with ALL the C/Ds I worked with was that they were shipped in to relieve an order "Glut" at the time, and then six months later when the jobs hit the shop floor, the land mines would start exploding. Their drawing skills were not the problem, but an alien (to their training) working enviroment didn't help when "Dropped in" for a few weeks contract. I'm also sure that Steve will have been "Involved" with "Designers" whose best use for a piece of pointed graphite would be cleaning their ears out with it.
 
  The use of an "Illustrator" for the Mag. is not a problem PROVIDING the information given to them is correct from the outset. We had a superb "Tracer" in my first drawing office whose pictures were like works of art, (SHE was pretty fit too) BUT had she been asked to design a press tool would have had no idea despite working in that enviroment for many more years than I had.
 
 A basic rule I worked to when designing bits to be assembled on "The Line" was ( and don't get your knickers in a twist over THIS one Ramon) make sure it can be assembled by monkies, and if you have a trained monkey, regard that as abnormal. Now I'm NOT insulting ALL shop floor workers, but many are motivated by ONLY the brown envelope at the end of the week, so making "Mindless tasks" had to be the norm and you NEVER stopped "the line" on pain of death, alarm bells and a Mexican wave of inactivity along the assembly benches is VERY frightening.
 
 So rounding back to the drawing representation, and given that you have to cater for all levels of mechanical knowledge from a road sweeper to a brain  surgeon and all points in between, although some "Authors" might have delusions of becoming ace Drafties at some future point and work to BS/ISO or whatever current standard, I find it far more important to have an unambiguous and DIMENTIONALY CORRECT representation that ANYONE can understand without having to think 1st 3rd or whatever (Where's the truncated cone drawing).
 
  Summat else to chew and digest,
 
  Regards  Ian.

At least we all seem to be working on the common sense page,sadly due to pressures from the "Lets all go Metric" brigade, things went awry when some tried to "Double dimension" drawings A La Opus Approximus and others.
 
  Yes qualified Drafties DO make mistakes, and the economics of test building and checking  is a luxury that the toy comic trade can ill afford although to hear SOME of the complaints, you would think that it was intentional. Some of the day jobs of some muddlers must show perfection at all times??

Thread: Drawing projection, first or third?
25/02/2010 07:34:00
Dimension from two datum planes only. Yep I was taught this at school, but in the REAL world of imparting numerical information for manufacturing, logic takes over.
 
  OK Ramon, consider the frame plates for a loco. When you start marking out from one end, which is more important? Having the cut outs for the wheel centres in an exact position to the frame end or to EACH OTHER and additionally should the hornplate holes be dimensioned from the frame end or the hole they are dispersed around??
 
  I remember on one forum that a Drafty working for BR mentioned that if he dimensioned using sub datums he would get a "Talking to" by his superiors. Believe me, I have been responsible in the past for having items made as a sub contractor and supplied to BR and the worst part at the start of the chain was to have to translate some ( quite a lot) of the said renderings supplied by the Ivory tower into PRACTICAL manufacturing information.
 
  It's no good that some, who are activey engaged in the generation of drawings in a manufacturing area to state BS (Bu** S***) whatever to the attendant masses, but in trying to give instructions to someone who hasn't had the luxury of beng taught how to do it "Properly" the simplest non ambiguous drawing should take precedence.
 
  You want to "Play" with the various "Instant Draughtsman" programmes?? Fine, but leave the pins and eggs in the drawer when trying to teach some of us teeshirt/video makers the ropes.
 
  And before someone states the old nugget "A drawing saves a thousand words" Get real. A couple of lines of notes on a drawing saves any confusion if notated correctly, -- Oh heck, I am ASSUMING (yes, I've heard that one too) that the subject can actually read.
 
  Regards  Ian.

Snap Gordon, beat me to it, put "View in direction of arrer" on the drawing and avoid the confusion. Ex drafty also. In "Technical drawing" at school, we were allus brunged up wi First angle or "English" projection and when going to "Tech" it was a daily bone of contention between the two factions who worked in D/O's where one or the other was the norm.
 
  The Arrer don't lie.
 
   I think todays electronic Etch-a-sketch drivers would have a good cry if they got  graphite on their arms. Gawd elp us when some bright spark decides to start putting geometric tolerancing on our "Toy" drawings.

Thread: Badger Mini Abrasive Gun

Shot Blasting, generic term like all vacs are Hoovers, and although a different media and applicator is used, Grit, sand, bead and vapour fall into the same classification. Initially coarser grade were used to strip and clean the metal surfaces, but then a "Sealing" operation using metal or glass beads closed the surface the former had cut open.
 
  Another problem not appreciated is the cross contamination by using "Used" blasting media. Stainless Steel and Alumininininium "Rust" quite well if you've done a bit of mild steel first.
 
I think the aircraft industry picked up on the walnut shells as that was the developed method for removing the crud from airfield marker light glass covers in situ rather than strip and scrub.
 
 
 
   Not going to have a go at anodising Ramon??
 
   Regards  Ian.
 
 Missed the bit about "Grit", Grits and sand have sharp corners wheras glass beads are exactly that and impart a "Peening" opeation.

Meyrick, you can add all the Martensitic or Austenitic or Spheroidal graphite or altropies you like, but unless one has the ability to ACCURATELY measure the temperatures, Dull red or Bright red or Cherry red??? are the easy ones for us general dobbins to use. As far as tempering is concerned, I keep throwing this one in, a VERY efficient source of a tempering "Oven" sits in most kitchens and providing that the bits are CHEMICALLY clean and no trace of oil or other detritus. You can set the thermostat on the domestic cooking oven and dangle the bits on wires from the racks and WATCH them go the right colour.
 
  Sundays works best in our household as the chamber is already up to speed (Or just below it) after the luch is prepared.
 
  Did all the theory bit in the lab where I worked when an apprentice Meyrick and had the crazy paving diagram stuffed under me nose, but I don't have access to the salt baths, Lead baths tempering furnaces OR the measuring and inspection tackle to check it with anymore.
 
   Regards Ian.
