Fixing radio coils with the help some of polyester resin and plaster

The video tells everything. Fixing radio coils (at their ends, end-electrodes) with polyester resin and plaster, mixed with some hardener to make it cure after (say) 5-8 minutes.

Of course don’t immerse your radio/antenna coil with this mixture of resin/plaster. Otherwise the Q (=quality factor + resonance frequency) will be gone (!), due to the damping of the plaster/polyester resin.

So it is (only) usable to fix the “ends” of a radio coil, but sometimes not otherwise.

Correction: somewhere on 00.23 in the video I seem to say "etch", but I mean "end" (or edge).

Fixing the “ends” is showed here. You can mix the combination resin/plaster (= the volume ratio) to any extent: from a free flowing material to a paste or to a “lava like” creep material.

It all depends on the amount of plaster related to the amount of resin. Make a “paste” or a more fluid substance, whatever you need.

By the way: I did not test the complete covering of a radio coil with this plaster/polyester resin combination. Perhaps there will be a certain resonance on frequency “X”? Perhaps someone wants to try this out and give a report, I am interested.

My You Tube channel trailer is here: When you search, search always “NEWEST FIRST” to get the right overview. You can also search via the “looking glass” on my Channel trailer via keywords like ”audio”, “radio”, “amplifier”, “filter”, “Shortwave”, “transistor”, “FET”, “oscillator”, “generator”, “switch”, “schmitt trigger” etc; so the electronic subject you are interested in. My books about electronics & analog radio technology are available via the website of "LULU”, search for author “Ko Tilman” there.

I keep all my YT videos constant actual, so the original video’s with the most recent information are always on YouTube.

Search there, and avoid my circuits that are republished, re-arranged, re-edited on other websites, giving not probable re-wiring, etc. Some persons try to find gold via my circuits. Go to You Tube for the originals.

I take distance from all these fake claims. I cannot help that these things happen. Upload 2 December 2021.
