seems right, the tinned part throws me off a bit too but it’s still allegedly copper so it shouldn’t affect it too much, will make it easier to solder.

It is, that its why the “silicon wire” it’s silver and not copper color! The same happens with Copper braid and tinned copper braid.

Yes. They tin copper to prevent corrosion so it’s normally used in outdoor / marine applications where bare copper would turn green after a while.

Copper clad aluminum is what you want to watch out for. It’s terrible.

Yup, UL 3135 Silicone Hobby Wire. (680 strands per 12awg 4 ur case)

All of our (correct) wire is tinned OFC. It’s like, a few molecules thick plating or whatever, but it is “tinned” copper, aka why it looks silverish & not copperish.

The issue, not in rc hobby silicone wire, but other types - is CCA, AKA Copper Clad Aluminum. It is complete junk & literally corrodes into dust.

@tech.shit it is indeed tinned copper in our wire. Or at least, the wire we want to be using.

The biggest issue with buying on Amazon at this point is just making sure you aren’t getting sold chinesium or CCA despite what the listing indicates. If not using HobbyKing, I’ve always preferred OG high reputation AliExpress sellers

I’ve known about it for more than a decade at this point but I’ve still never watched / searched enough to find a video that shows the process for the strands this small… like I know it’s just electroplating (I think) but I’d really like to see a close up & detailed process of how this shit is actually made.

I imagine the strands come off their initial rolls, then get tinned, and then combined into the larger size multi-strand cables

No idea though, would be neat to see the process.

I need to refill some previously used enclosure mounting holes. I’m thinking some kind of epoxy putty. Any proven materials?

If it’s a fiberglass enclosure, the best is epoxy with a thickener.

I’ve used System Three and slowly added silica until it hits the consistency of peanut butter. Or any of the usual epoxy suspects will work

If it’s a wood deck, i would try filler putty designed for wood before epoxy

@Halbj613 has some experience in this. No idea how well it worked

will do! lol. im still considering whether im gonna do a skin on this one or just stain n frit. prolly end up skinning it, just to hide the existing holes, unless i manage to blend em in real well.

i was putting inserts in afterwards so mine was a little different
i found wood filler to be to brittle and just fell apart

gorilla epoxy is super simple to use and is perfect for me (become a bit of an addict to gorilla epoxy)

gorilla products are just good. i use their tape for 99% of my waterproofing. hell, the stuffs been holding the pipes together under my sink for almost a year now. it is actual hell to remove, though.
