Gentlemen, It has been suggested that ideas and challenges can often be resolved by our subconscious overnight. But don’t let it become a habit. Like Steve, I woke one night (without the help or otherwise of sherry), only to realise a potential problem at work. I had missed some important parts (ejector push-back pins) from a mould I was designing. Immediately, I fell asleep again. Sure enough, the following morning when I removed the cover from my drawing board, it was clear that the pins were indeed missing. I decided however, that since I was only being payed for daytime work, my overnight problem-solving practice should cease. The year was c.1960. To pick up the thread again, shouldn’t what has now become known as `Sam’s test’ require at least some semblance of Velcro loops and hooks, or an indication of magnetic polarity and lines of force?
Or is the logic becoming too fuzzy.
Regards to all,
Sam
PS Would lines of force be in 1st or 3rd angle? |

| 837 forum posts 27 photos | I do like the occasional glass of sherry, but I don't go overboard on the stuff. But there again, I wouldn't dream of drinking cooking sherry either - only decent brands. And I don't think sherry was what caused the cold sweat - I'd have had to have drunk rather a lot for that to happen! As for the lines of force, I think the most fun would be to only include them in the isometric view. And at least there's a sort-of convention for drawing those - how are you supposed to indicate a gravitational field? |

| 1294 forum posts 108 photos 1 articles | I think a solution must be regarded as legitimate, even if it might be difficult or impossible to actually build it. The point after all is that the original two views are actually ambiguous, in that there is more than one way in which they may be interpreted. hmmm...I think that means that there would be solutions with two parts that don't actually touch each other. regards John |

 5068 forum posts 3 photos | Shouldn't post on Sherry, likes, dislikes, brands etc be listed under the coolant thread where it's more relevant or even the cutting oil thread given that the damn stuff is more like ATF than a drink ? John S. |

| 837 forum posts 27 photos | Hmm.. a few moments additional thought reveal a conceptual problem with the convex design... I'm not sure that one of those will work at all. So unless something else spectacular happens, I'm sticking with the above. Using sherry (or anything else alcoholic) as cutting fluid might be quite efficient - assuming, that is, you want to flame-harden your work whilst you are cutting it! It is potentially a slightly worrying line of experimentation though - similar to Edison's early attempts to create electric lamp filaments using the basic food groups... |
