" Rabbit is not only valuable fur .........
Самолёт не "Ту-154". Это "Як-40", навскидку.
What about the make of the car?
Weak. But I've seen the clip somewhere. :)
This one -- it's severely trimmed.
It's not what you all think ....
It's a new russian airbus!
(Claimed to be a direct flight from Moscow to New York)
On the subject of aeroplanes:
A sysadmin's tambourine
100 Download the markup file: razmetka.rar [attached to the post].
200 Print out the mark-up file.
210 Get unwanted CDs and DVDs (one each)
220 Buy screws [9 screws with 4 mm thread and 30 mm length]
230 Buy nuts [9 cap nuts (4mm thread)
240 Buy nuts [45 4mm nuts] // (there is an alternative to screws - pen rods - but they are worse, imho)
250 Break 18 floppy disks and remove rings from them
260 Prepare Tools [strong and long scissors, office knife, drill, screwdriver, spanner, marker]
300 Cut out the inner circle on the marked sheet (you can also cut out the outer circle if you prefer) // see line 200
310 Align the disc (normal CD) with the large circle on the mark-out sheet and draw a ring around the inner circle so that the rim is marked out on the disc.
320 Cut out the rim.
321 You need long, strong scissors - make centimetre-long radial cuts from the centre hole - to the plastic embossed ring on the rim - then break out the resulting sectors.
322 The strips of plastic are cut away from the disc with scissors in a small spiral pattern. Take care not to bend the ring too much in the process - they often break, but I think you can do it with a third of these - you have to cut about 5 turns to reach the marked ring
323 Use a stationery knife to cut off the irregularities inside the rim ring
324 If the blank (not the purchased disk on which the picture is printed), the same knife is used to carefully remove the glossy layer - it should be picked up and removed (the glossy layer is where the cover is). If you have something printed on the cover (you bought the record as a CD), then the glossy layer is not dusty and can't be removed.
Warning!!! This glossy layer (in blank bolsters) with any operation likes to turn into glitter, which will then be all over the place! They are very bad to wash off or wipe off afterwards - so I recommend doing it over newspaper and take care of your clothes.
330 Membrane fabrication: use DVD - when you look at it from face view you can see it's double-layer - use same stationery knife to cut it - slide the knife in between layers. I recommend TDK or Verbatim. There is one more catch - between layers there is indelible shiny layer and on which half of disc it will stay - natural mystery, so if knife has entered between discs and you look on it from lilac side ("mirror") and you see the blade from this place, insert knife further and as though cut layer between discs - along circle, if knife is hidden under shiny layer - try to split from other side. The result should be a transparent and thin lilac disc - this is the know-how
340 Next, from the marking points are transferred to the ring - and there are drilled holes, then from the ring are transferred to the diaphragm and also drilled (it is better to mark the holes on the diaphragm by already existing ones on the rim - so there is less error)
350 Drill better with a drill or screwdriver - drill 4mm and better for metal. If you don't have a drill, you may use a knife, but you have to be careful. The quality will be worse, but you can live with it. After drilling you need to deburr the holes.
{ Attention!!! You should categorically not try to make holes with concrete drills, rotary hammers, demolition hammers, conventional hammers - the disk will instantly fly away}
400 Assemble the tambourine from the parts:
410 Insert the screws into the diaphragm and screw on two nuts each - just screw it on without screwing it in.
420 Fit one diskette ring each to the screws.
430 Put one nut each on each ring (know-how ) - this is used to prevent the rings from "sticking" and improve the sound.
440 Put one more ring on each of the three nuts.
450 Put the rim on
460 Screw on the caps.
470 Align and tighten - finalise all the nuts near the diaphragm, then fit the caps, so that the rim is level - finalise the nuts under the rim. The middle nut should just be loose - in use it will still take up an arbitrary position between the floppy rings.
{Be careful!!! Do not tighten the nuts all the way in! If you overtighten - the disk will split - it will be immediately ugly and will break soon - i.e. as soon as the nut stops screwing on by normal pressure - you should leave it like that. The second nut - which is on top of the nut, not on top of the plastic - should be tightened as much as possible - it is a counter nut - it is needed to prevent screws from unscrewing later.}
500 The end.
Where the bugs arise:
1. making the rim - the disc breaks if you bend it too much - as the cut goes from the centre of the bend cannot be avoided, but you have to be careful.
2. Splitting the disc - the shiny layer between the discs can remain on either half - you have to watch out for this.
3. Finishing nuts - do not over tighten or it will crack.
Every problem is solved with the 3rd time. If you do not leave it as it is, but fix it, the result can be very good. If you do not break the technology, the result is quite survivable.
