How to make cheap glue equivalent (super glue ) Plastic filings25-35 grams and 100 grams thinner( acetone ), For Coil...All the best

[WM6]

Acetone and enameled wire?

[sinclairuser]

wm6 is correct, dont use aggressive solvents(mek,acetone or cellulose thinner) on enameled or teflon or ptfe coated wire.

You can try on a piece of enamelled cooper,i tried and nothing happened soon evaporated as the diluent...

[WM6]

Evaporated on air, but not mixed with plastic filling. Put piece of wire in bottle with acetone for 20min and then check. Except if you have special diluent resistant enameling it will be macerated.

Let's see. Acetone $10 Superglue 4 for $1...

For the last 40+ years, I've been using Q-dope for hand-wound coils used in ham radio.
Acetone and Styrofoam (polystyrene packing peanuts) is all it is.
1 pint of acetone will last a lifetime for solvent.
I usually only use 5-10 milliliters of acetone and keep adding packing peanuts while stirring until it gets to the viscosity I want.
Thin for soaking in on bundled wire coils and thicker for coating.

Never had a problem with the Q-dope stripping the insulation off wire. Not even the wire removed from old B&W TV picture tube coils. They were varnished. The new wire I buy is more often than not nylon coated. No problem with these either.

Every package of super-glue I ever used was one-time application.
Q-dope dries out a bit? Just thin with acetone or mix a new batch.
So the price aspect is a red-herring argument.

exactly SD, one mans short cut, is another mans scenic route.
as i have said before, what is cheaper in one place is more expensive in another.
for instance ready made flux(quality) is cheaper here than a puck of rosin, so soaking your own does not make sense.
elsewhere in the world the opposite may be true.

Sorry to intervene, this method is the dictator Ceausescu, I live in Romania and that time there was no super glue, so we did (acetone with plecsic) but try and you and you will see that it will not happen anything email (put more than plecsic diluted in acetone or acetone reacts not ...) and now everything is quite expensive to buy super glue the coils, the average salary here is $ 250 and a super glue is $ 2,acetone in Romania is cheap ... and electronics is a bit expensive in Romania ..

take a look..

[sinclairuser]

you kind of agreed with my argument, if it works for you use it, but in the uk we can buy 10 tubes of super glue for a pound from pound land, also all solvents like mek, acetone etc are strictly controlled(and not readily available), acetone is available as nail varnish remover, but its watered down with water and does not make dope i know i've tried on a particular project.
just use what is easiest for you to obtain.

You can buy acetone from fibreglass supply companies, in UK. But not sure the minimum size/quantity, and probably extra fees apply for hazardous shipping. As an aside, same place to get glass micro-balloons to mix up with your resin when potting your coils.

pure acetone from the chemist. Boots sell it you have to ask for it. Still don't see the point for our installations.

Now how to make cheap potting compound? It's $35 for a quart of the good stuff around here.

I've heard of using MEK and ABS plastic to glue the housings together...

[sinclairuser]

that could be more difficult here soon, seen a report recently and if a particular body has their way all potting compound used in industry will have to be the biodegradable gel type.
which means the resin will disapear, and hobbyists will have to use the gel too, have you seen the price?, i'm just going to buy in a couple of gallons of the good stuff(loads cheaper here in bulk), if i use micro balloons it will last even longer.
