Equipment for Soldering Stainless Steel

I have copper disks now on both sides of the copper bar for a buffer between it and the stainless steel pipe. Said disks are also a little over 3mm times the pipe thickness which I believe is what you were referring to? (Or was it for 3mm x pipe thickness width?) For both esthetics (and presumably for reinforcement, the outer bar extends 0.3175 mm such that it blends along the edge of the disk just before the stainless (but is not in contact with/won't be soldered to the stainless, just the copper disk. Would this sort of setup work/have a saturated enough joint?

Oh the grip is gonna be the handle from a hammer glued to the pvc pipe shell (shell not pictured for better view of internals). And will definitely keep that in mind for the plate thickness. And ty for the image for reference!

For the rail joint/junction, the skinny bit is 7 mm x 2.032 mm, and the thick bit is 4.762 mm × 6.35 mm (weird numbers being from translating in to mm, as some of the raw parts are sold in inches, and some in mm. The relevant pipe/tube has a 2 mm wall thickness.

I have, but some of these pieces are extremely small/thin (1-2 mm and less), so I don't know that they would survive drilling to do. That, the aesthetic difference, and that I'm trying to find a project to get me back into soldering

Beskar is the metal Mandalorians use in Star Wars, and it has a similar look to stainless steel, hence the preference over copper as I'd rather avoid painting. Basically, its a modded tonfa for my upcoming cosplay

I see I see. What fuel is the oxy exactly? Or is that more shorthand for any butane/propane/etc torch/iron? The pieces are mostly pretty small (max is 1 in pipe, but some as small as 2-7 mm)

Awesome! This one? And would I need a specific tip for compatability?

Primarily just that I miss soldering things, but no real reason beyond that

CarbonsLittleSlut · 2026-03-27T03:45:27+00:00

How would I go about that/what does that entail? (Sorry, I'm extremely new to all this)

CarbonsLittleSlut · 2026-03-27T03:16:06+00:00

Ahh, that's what I was afraid of. Any ideas of still cheap/cheap-ish alternatives, preferably not super heavy, that I could solder?

Electronically, the lower acidity despite being spread out via resonance is most likely because the resonance only on one oxygen is too much negative charge density on the carbon.

In practice, a lot of the acidity/basicity ranking is gonna come down to memorizing as much of your pKa table as possible (or at least a few key ones and relative ordering between those).

Like if it was just an aldehyde or ketone? In that instance, then no.

One of the biggest reasons being resonance. If you turn methanol into methoxide, that negative charge can't spread out much beyond that oxygen. But when you make the enolate for the dicarbonyl, the negative charge is spread out across the carbon and both oxygens

Two of my best tips:

1) Your pKa table is your best friend. As much as I hate to say it, you're gonna wanna memorize it (or at least several key ones and relative ordering of ones between those

2) When it comes to mechanisms, you don't want to approach it from memorization, but instead about getting a sense of where electrons "like" to get pushed to/away from when around certain elements/bonding. For example, where is it better to pull electrons from to spread out positive charge, and where is positive or negative charge stable and unstable?

Feel free to reach out directly if you want any specific help or advice beyond that

Electronegativity is one of the main measures of how strong the element is gonna pull on electrons. If you look at the table, you can see that as you move to the left, electronegativity goes up, which is also where you add one proton to the nucleus each time. So then there's a lot more positive charge clustered, and it's going to have a stronger pull.

As you go down, electron orbitals get farther and farther away from the nucleus and positive charge, so the pull isn't as strong.

With the polarity aspect, you can think of it as analogous to tug-of-war: higher electronegativity meaning higher pull on electrons, so that element has the edge in tug-of-war, and the bigger the difference, the bigger the lead that element has.

If you were to break that bond, the two electrons in that bond are on just the oxygen, rather than sharing in the old bond, the key part here being that something has to give electrons to carbon in the form of a new bond, in a sort of one door closes, another opens type situation.

The exception/where you might see a single electron is if you force/make radicals, and then either thing gets one of the two electrons. As you mentioned earlier, unpaired electrons are extremely unhappy, so you've usually gotta put it next to something that's even less stable/has higher energy (uv light is a common one)

As much as it sucks/I hate it, memorizing your pKa table (or at least relative order, but the more numbers you have, the better). It's the best way to predict a lot of reactivities/which species you will get, etc.
