Hi all i make good use of heatshrink tubing in installs but sometimes space is at a premium, am i right in thinking there is a paint on insulation similar to conductive paint that bonds to soldered joints, kapton tape though thin doesnt always stop on small joints as an option to heatshrink.

Best Regards.

***There is a paint on insulation but its about as thick as heatshrink.

Appreciating the space constraints of N scale, you should try.... Painting with superglue... it may take a couple of coats, but it dries to a hard insulating layer. Nail polish also works.... It is worth making sure any sharp dags are flattened/filed smooth first.

Thanks Richard,

Of course superglue is a good solution ...... sometime the solution is under your nose

***Almost.

If it was that dangerous it'd not be on the supermarket shelf.

Heating Superglue certainly does create some irritants that will annoy your eyes or nostrils, (various polymers) but it needs to be actually burned to create any amount of cyanide....and you'd not get enough from an entire tube to hurt you unless you burned the glue in a box that was also containing your nose :).

The gas from hot superglue is used routinely in law enforcement to fix and make permanent fingerprints - this procedure involves heating the superglue to between 100 and 200 C to release all the vapours/polymers which then fix to the fingerprint (same stuff as that annoying cloudyness that happens when U use superglue in a closed area).

Good advice from you all ........

(same stuff as that annoying cloudyness that happens when U use superglue in a closed area).

Some years ago i raced R/C cars in competition and superglued the tyres on to the rims of course, the cloudiness or 'kicker' as it is known left the white residue, on my workbench i had a 12V fan set up for cooling a powersupply, if a stream of air with a fan is played over parts superglued the kicker residue is blown away and doesnt get a chance to settle on your workpiece as it is setting ........ a good cheap source of these fans is your local pc shop where one costs about three pounds my fan its about three inches in diameter and came with the shroud complete.

Well you learn something every day.

In addition to model railways I also keep tropical fish and I recently designed and built an aquarium filter using 3mm black acrylic sheet. When I used superglue to assemble it, I suffered from quite a bit of this white residue and now I know why.

It was, incidentally, not a major problem as it cleaned off with jewellers polish.

In case anyone is interested here are some shots taken during construction, complete with white residue, and when it was finished.

Bet you never thought you would see anything like that on the MRF

Well as fish & things aquatic have now entered the thread I can report that there is an LGB bogie tanker at the bottom of my fish pond (at least I'm sure it's there - I never found it after a derailment).

Does just qualify to go on this thread - after all the LGB is DCC !
