The shape of things to come ... ?
So the week got off to a great start. I've got a Dual CS505-3 phono deck on
the bench. It all works hunky-dory, except it's a bit slow. This is because the pitch belt has snapped. So I'm pulling a new one into place, and the pliers catch the flat leaf spring that couples the speed select knob to the belt shifting lever. It only holds in there because it's bent and under tension. And of course, it detaches and flies ... I have combed every square inch of the floor under light strong enough to burn your eyes out, but nope, it's gone ... So now, I've got a deck that is 33 or 45 rpm only, depending on where you leave the belt shift lever set. I've sent an email to the company responsible for Dual products in Germany, pleading for them to help me out with a replacement, but I'm not holding my breath. About the only other alternative is to try and fabricate one. I've spotted an old octal based relay where the moving contact fingers look big enough, but the length is absolutely critical to get the right spring 'snap' action of course, and I don't think it is going to be easy to achieve that ... Don'cha just HATE it when **** like this happens :-\ Arfa |

However, the best way is to enlist any available small kids to help with the search. They're not fast or efficient, but they have better eyes than me. That requires the availability of small kids. Going to the streets to aquire small kids for screw-related problems might lead to unpleasent experiences.

Yep, shapes of things..
It seems to me that when I was younger, my ears could tell me almost exactly where a flying part landed, without even turning my head.. like a bat sense. Maybe the parts were bigger then. Seriously though, parts in recent electronic gear have gotten so small it's absurd, and their means of retention is insane. I've found some very small items with the bright light beam parallel to the floor method.. it's a reliable method if the missing piece is on the floor and the floor isn't covered with dust and debris. A good 1W or better LED flashlight with a good reflector for a fairly tight beam works well. I have a telescoping magnetic parts reclaimer for steel parts which also has an LED light on the end, works on steel parts that are out of reach, and in the dark places between stuff you'd prefer not to move, under stuff etc. Otherwise, an old speaker magnet or newer high power magnet on a stick, like sweeping for mines.. sometimes you can hear the click, when the part jumps to the magnet. It's often fairly easy to determine which parts are likely to and capable of flying great distances at a very fast rate of speed. Using a cover over the area will restrain flying part from exiting the realm of one's attention span. Build a 3-sided booth with an enclosed top, lined with sticky rodent/insect trap material. Strong magnetic panels, same booth style. Very high speed video of the work area and "all ya gotta do is" play back in slow motion. -- Cheers, WB .............. "Arfa Daily" wrote in message ...

Also, did you look on top of things, it may not have landed on the floor. I've looked everywhere. As it happens, the workshop floor isn't actually all that bad at the moment. I used one of those outdoor 500 watt halogen lights today, but still no sign of it. The thing is, the plastic dust cover from the deck was leaning against the bench leg just to one side of me, and I heard it hit that, so the fact that it is springy in itself, coupled to the fact that it hit a large area of plastic, and was probably travelling at some speed because it had 'popped' from a location where it was under tension, means that it could have gone just about anywhere, and it's quite a big workshop with a lot of stuff in it ... :-( Arfa |

I used to have a very similar 'tongue in cheek' theory as well several years ago. I used to believe that all of the faulty electrons flying about in workshops, caused tiny little molecular warp holes to appear in the floor, which if left alone, would slowly 'breed' downwards, following a curve as they got deeper, until as they became horizontal, they suddenly shot back up to form a fully stable warp tunnel that often as not, would come up somewhere dark or under a table leg. Components and other important bits (like my spring) are attracted to them, and as they fall into the hole, it closes behind them. The item is then 'conveyed' through the warp hole until it emerges under the table leg, never to be found again, until years later when you move the table. And that, I think, is what has happened to my spring ... d ;-) Arfa |

I've found some very small items with the bright light beam parallel to the floor method.. it's a reliable method if the missing piece is on the floor and the floor isn't covered with dust and debris. A good 1W or better LED flashlight with a good reflector for a fairly tight beam works well. I have a telescoping magnetic parts reclaimer for steel parts which also has an LED light on the end, works on steel parts that are out of reach, and in the dark places between stuff you'd prefer not to move, under stuff etc. Otherwise, an old speaker magnet or newer high power magnet on a stick, like sweeping for mines.. sometimes you can hear the click, when the part jumps to the magnet. It's often fairly easy to determine which parts are likely to and capable of flying great distances at a very fast rate of speed. Using a cover over the area will restrain flying part from exiting the realm of one's attention span. Build a 3-sided booth with an enclosed top, lined with sticky rodent/insect trap material.

I'll bet that you're bad at playing pool, too. Probably an eye-brain thing. Something moving fast outwards, in peripheral vision at 3 o'clock is interpreted by the brain as being at 5 o'clock, say. I'll have to take notes the next time. |

Only one problem with the magnet theory. The part may well be stainless.

Some stainless steels are attracted to a magnet!
True. And an AC electromagnet (such as bulk tape eraser) sort of repels non-ferrous metals. The sound of the part banging against the eraser might help you find it. |

There are those enclosures for handling hazardous materials or a
sand/beadblast cabinet could be utilized and those even have an outlet tube for recycling the media. That's where the paper cup would be placed to catch the miniature part(s).
