Make your own solder

Certainly. You will need a vacuum pump, bell jars, hosing, a flat table, and other expensive stuff. Submerge the hollow solder (it may be expensive time-wise to make the solder hollow) into the cup of resin. Pull a vacuum. Wait an interminable time to allow the rosin to creep into the solder's void. Release the vacuum.

While you are waiting, I can send you 10 inches of rosin core solder for a mere $10 just to tide you over.

Yes, of course.

Ahh, that's the secret. I was making a thin noodle of rosin, freezing it with liquid helium then wrapping a precision sheet of tin/lead around it. Of course, then I used an e-beam welder to weld the seam. Don't even ask how I made multi-core solder.

Oh. Well, now you're needs are getting exotic. That requires a bevatron at minimum which isn't cheap. You got some country property?

Good luck.

You can always rob the raw materials out of the heart/lung machine you're going to need later in life.!

But to your question, it's easy. Freeze the solder, then drill it out on the drill press to make a hollow cylinder to accept the rosin. Think: Drinking straw.

You broke into area 52?

Casting solder is trivially easy. Just put the rosin on teh outside.

Slag can be cast to make building blocks. Make them big though, they crack a lot.

Can you get ahold of another hit of that stuff and send it to me?

Thanks, Rich

Thanks, Rich

Aren't the continents just slag floating on "top" of a huge spherical pot of magma?

Thanks, Rich

But I do wonder how they make the stuff. Start with a solder tube, and draw it down, introducing the thread of rosin somewhere in the middle of the process? It probably couldn't be extruded all at once, because the molten solder would boil the flux and so on.

Does anybody know for real, or who/where I could ask?

Thanks! Rich

:-) LOL Roll the tin flat, putt the tree with rosin on it, and fold it like a cigar.

While we're at it, how 'bout flux-cored welding wire? That's STEEL!

-- Cheers, James Arthur

Extruded wire, where there is a hollow pintle that 'inserts' the inner core. Easy to do both single and multi-core solder that way.

That's easy. Just coat the solder wire with warm rosin on the outside, let it cool, and then turn it inside out.

Jon

You obviously didn't bury them deep enough.

If I were you, I wouldn't advertise that you have 'ores buried in your backyard. The sheriff might come and dig up your lawn.

Start with a big tube, insert a big core of whatever, as tight as possible, then draw it down like any old wire (well not quite like any old, but near enough)

Mineral insulated cable is drawn down, conductors, Al2O3 powder insulation and all.

Doubtless there are some proprietary tricks that they don't talk about.

But why? Real men don't use rosin core. We just use recycle solder from old circuit boards and mix it with liquid rosin.

Nah, that's pretty sensible. I've always said that my ideal project is making a computer from sand. (What's the technical equivalent of "gesamtkunstwerke?)

extrude it in a semi-plastic state. heat it enough,it gets soft and is easier to extrude.no need to melt it.
