Soldering copper question.

I'm working on a project that requires soldering a 1/4" OD copper tube into a hole drilled in the side of a 2" copper pipe. Will a soldered join (not brazed) be sturdy or do I need to do something to reinforce (cut threads into the tube and pipe, flare the tube and insert from inside, etc) it? There won't be a lot of stress on the join but there will be a small tap on the tube to there may be a bit of torsion now and again. Thanks for your responses!

Does Chromesteel disolve during copper-electrlysis with Coppersulfate?

Hi I want to refine some copper and change it to copper-dust-particles by means of copper-electrolsis in a bath of disolved coppersulfate. Since my copper is in smaller bits id like to have some sort of etallic basket to hold the scraps. I think i would like to go with a chromesteel-mesh i connect to the power. The mesh/basket contains my scrap-copper and the anode-sludge can pass thru the basket... The basket (anode) and the copper-cathode are connected to the powersupply. Now my question: I think the chromesteel shouldnt get disolved as long as i dont crank up the voltage too high or let it run without sacrificial copper at the cathode. If i would do that, it would start to split the water used in the solution and produce H and O. Bad. Also would slowly eat away the metals too. Bad^2 But as long as i have copper to be disolved at the cathode, it shouldnt do anything to my chrome-steel-basket, right? Thanks for inputs from someone who knows it better than i do :)

Removing chlorides from a solution to leave only metallic copper?

I'm trying to deposit metallic copper into a piece of wood and i'm doing it with a solution of copper chloride (the alternative pcb etchant to the ferric stuff). I want to deposit metallic copper into the wood where it has soaked in and remove the chlorides altogether. Bearing in mind that i don't want much in the way of another solution, how could it be done? Could I drop in some lead to precipitate out the chloride ions or is there something else that would steal the chloride ions from copper that wouldn't be too hard for a hobbiest to obtain?

how to strip large diameter copper wire

If you have say 2 inch or better diameter copper wire to strip here is what I do. I have ben in the scrap arena for years. Buy a large handeled pair of shears that are only for copper. They will look much like a large pair of boltcutters. Cut your insulated wire into about two foot lenghts. Get a large pot, the bigger the better and heat with an out door propane burner full of water. Place the cut sticks of wire into the boiling water fro about five min. Get some insulated rubber gloves and a sharp razor knofe and you will find that the plastic insulation carves away like butter. This works on everykind of insulated wire I have come across. With lead wrapped insulated wire, get a plasma torch. It cutts easily and is so fast the plastic wire inside does not have time to catch on fire. Use plenty of ventilation to avoid breathing lead based fumes.

recycling broken AC motors?

I love demolishing things for parts. Often a broken AC motor is left over. Usually it contains a decent amount of copper. But the copper is mostly deeply embedded in iron (a core or a ring around it made out of stacked steel plate). Since it has been put inside the iron there must be a method to take it out. Copper prices are very high. If it can be separated quickly without melting the whole thing down, I would consider doing this myself. How?

Effects on metal

So I really like this clock.  I think I'll buy it soon. But as a beginner's art project, I'm trying to replicate some of the metal effects here.  I'm curious for techniques on how to accomplish some things, like: The back plate is copper, which the artist says is "oxidized".  I expect oxidation to turn copper green, blue, or black, not this silver/grey color.  Any ideas how this was done?  Is it just that it's a light oxidation? I really like the metal texturing here.  I've been able to replicate something similar on copper plate by hand-sanding in one direction with a fine-grained sandpaper.  But notice the vertical texturing on the backplate - how would that have been done?? I like the polished metal look of the minute hand contrasting with the reflective look of the hour hand.  How would you do that - similar way as the backplate?  Same with the gear? I've actually made what I think are much prettier nails by taking old (originally quite rusted) square iron nails, removing the rust and grinding the crap out of them with a bench grinder until I get a cool reflective finish.  Doing the grinding in patches gives it almost a hammered metal look while keeping the reflectiveness.  I think the effect is cool and really works with the "old-but-new" look of the square nails.  I'll post before+after pictures if anyone's interested.

Electroplating Non-Metals

I'm looking for input on the process of electroplating non-metal materials. I have never electroplated before and am open to trying the traditional method or the paint on plate solutions that are available.  I'm just uncertain where/ how to begin and what to buy. The hurdle is that the items I want to plate are not metal to begin with.  One website I read seemed to suggest that painting the object with a paint that contains metal flakes (like Liquid Leaf faux gold leaf, which contains soluble copper) would be enough to get a paintable silver plate to bond. Anyone have experience to weigh in with?  I welcome suggestions for techniques, favorite products, etc.

I have an old house that uses steam heat and has big, single-pipe, cast-iron steam radiators.  I wanted to replace one of them with something modern looking, and one company sells such radiators, but they are very expensive (sold here http://steamradiators.com/) My question is, can I make one of these  out of large (1.5" or so) diameter copper pipes, soldered together in the same fashion?  I've read that steam systems typically operate at 1psi of pressure, which sounds like it's well below the safety limit of copper pipes and solder joints. I think it would look fantastic, but would it work?

Why should you build a rooftop lightning protection system with either all copper or aluminum components? Answered

I bought a book from Home Depot to learn about household wiring: http://www.amazon.com/Wiring-Complete-Editors-Creative-Homeowner/dp/1580111602/ref=sr_1_1?ie=UTF8&s=books&qid=1279657048&sr=1-1 On pg. 238, about lightning protection systems, it says, "...these instructions are for copper only-do not use copper with aluminum." Why shouldn't we use copper components with aluminum? It's essentially just a couple of lightning rods and a cable leading to a ground rod. I can scan the page if you'd like to read it. They made it sound fairly important.

How to remove the copper layer/film from a PCB ???

Hi ... do you know, how to remove the copper layer from a PCB - by not using any ETCHING METHOD. Just to separate the cooper from plastic/f.glass ??? Do you think, that HEAT would do the trick ??? Like when you hold soldering tip to long on a pcb, it can happen that the cooper film become loose from the PCB. Thank you in advance. Zholy P.S. : The reason, why I asked = I was thinking of creating/extending a "ribbon cable" : 1. remove the copper film 2. stick it to the foil, that you can laminate 3. put the "ribbon cable pattern" on the film and ETCH it. 4. laminate it ... and cut the just the top of the laminate foil at the ends, so you have clear cooper for the contacts, but the bottom laminate film as a support.

Chemistry Questions: What do you get from combining salt, white vinegar and cupric oxide? And what can be done with it? Answered

In my enameling work, I sometimes use a mild homemade pickling solution to remove firescale (cupric oxide) from copper. The pickle is a saturated solution of white vinegar and kosher salt, kept hot in a Crock Pot. After heating the copper pieces in a kiln, a layer of cupric oxide forms on the surface, which is then dissolved in the salt/vinegar solution. After a while, the solution turns a lovely blue color from the dissolved copper. If I forget to put the lid on the pot, eventually the solution evaporates, leaving pretty blue crystals that look a bit like copper sulfate. So, what have I got here? I don't want to just dump it due to the copper content. I'd like to figure out something to do with it, but first I need to know what it is. I'm thinking it might make a good electroplating solution, but that's just a guess.

i want to extract the tin from some tinned copper wire. how do i go about doing this?

hello, i would like to know, what the best way would be to separate tin from tinned copper wire. i recently attempted to build a MOT welder and now am left with quite alot of wire, and i require the tin for tin oxide. im wondering, what would i need to do, after i dissolve all the wire in hydrochloric acid, to extract the tin? its my understanding that tin and copper chlorides decompose easily into their oxides, and i only need somewhat pure tin,  as the electrode connector for my MMO titanium mesh (the part which will stick out of the cell which i will connect the cables to), and i only need roughly 70-80% pure tin metal, which i will reduce using my furnace and some pure carbon, in order to get a metal. or would it be ok for me to just melt the metals as is and let them separate in the crucible, and have all the fiberglass and resin just burn off? otherwise, would heating their chlorides (i require a soluble form to filter away resin and fiberglass), yeild tin oxide and not copper oxide, or would weaker acids like carbonic acid be able to dissolve the tin? sorry for all the questions but i really need some tin and i dont wanna blow this one shot i got here! i already have a theory on how this will all work, i just require a second (somewhat) proffesional) opinion. also i am already taking full precautions to ensure i dont get chlorine poisoning, so dont bother with the warnings. thanks.
