D.i.y. (plastic) nuts (for any kind of thread) Answered

for emergencies or simple application:
how to make your own nuts out of (p.e.t.)-plastic bottles:

take a bottle (#1 plastic, preferably smooth, w/o imprinted patterns or design etc) > cut off bottom and neck > start cutting (scissors) > the resulting ´tube´ into a consistent (width, depending on desired usage), slightly diagonally, thus sort of ´peeling´ it > wrap the strip around the screw/threaded-part/etc you need the nut for twice (for a start) > ´melt´ the edges of the wrapped part = joining them (i use a little solder-iron) > this way the wrapped beginning of the strip wont come loose > ´brush´ with the solder-iron (or whatever other source of heat) over the wrapped part (w/o) burning holes in it > this causes the plastic to shrink and press down into the thread and adopt its shape > once set keep doing more wraps of the rest of the strip until you reach a desired diameter > now, again, join the edges of the wrap with heat, and afterwards brush again over the outside of the created ´nut´, so that the plastic shrinks down & compacts > after having cooled off: unscrew the ´nut´ with pliers > ready for use

ps this is just a simple sketch. got no camera to take photos. sorry. so, please, ask whatever if you got any question. and any kind of feedback is more than welcome. bowing.

Sounds possible. A lot of plastics will shrink when heated. Perhaps heat the finished product with a heat gun or heat the bolt with a blow torch to get a better imprint of the thread.

_a, havent played around with all plastic ## yet, but p.e.t (#1) works/shrinks like a charme
_b, ahhh, yes, sweet: a blow-torch would be a nice toy around to create all kind of havoc (but am living a very simple life/death here). but, yes, heating up the threaded part does help. before starting to use a solder-iron (faster, cleaner) i actually ´baked´ nuts in my little woodburner here (did wrap some string the farmers around here use to pack hay around the thread and heated it up in the stove - compacts/melts beautifully)

If you do just a copy and paste job then it would be nice to correct the foramtting as Instructables does not do this properly.
