As someone who basically only ever fixes analogue crap, and mostly things made of wood: You people and your electronics skills are amazing!

My last project was fixing these 36 year old Nintendo.

I cleaned them inside, fixed the buttons that didn't work ( I couldn't find a button for the one that is missing), battery connectors and put them on eBay for sale. Got them sold withing a couple of days for about $150.

I also fixed an old ipod and sold it for $30 :D

Ooooohhhh man! I loved those toys when I was a kid. My best pal brought a bunch back from japan when we were 13. Donkey Kong rocked! I had the treasure hunt one and the one where the ninja defends the princess from attackers. I wonder what happened to mine...,

Yep, they were treasures I had back home in a drawer. Hey, did you finally get a Macbook Pro?

No, I am distracted at the moment. I am still planning on buying one. I just had some very big projects dumped on me so the macbook is on hold.

Aluminum Soldering

Post by Sclass » Sat Apr 13, 2019 6:50 am

Fixed a pinhole in a car radiator yesterday. I thought it would fit well here because it was a skill that was easy to learn and didn’t require much investment. But the potential to save money is large. I rescued a $400 aluminum racing radiator core that got nicked during a condenser core install (doh! :shock: ).

This was all on YouTube so I didn’t plan on posting it. I honestly learned all of it in a few moments of desperation clicking videos on how to repair a hole in an aluminum radiator after I damaged my core. It was that easy.

Basically you can do low temperature aluminum brazing/soldering with these $13 (20% coupon) rods at Harbor Freight. You can make strong repairs to broken aluminum stuff.

No fancy torch required. I used a propane torch I picked up for $1 at a yard sale last summer. The barrier of entry is low. Not true “welding” but it’s a technology that allows you repair metal.

I wouldn’t trust it for anything structural but it worked really well on my radiator.

Saved me some money yesterday. I almost posted it up in the Teflon = cancer thread. My lungs were irritated for an hour after the job. I think the rod contains some powerful acid to deal with the aluminum oxide coating. Beware of the smoke. There are also some pretty orange stains on my driveway where I did the work. :lol: now that stuff is in my lungs. :?

Sorry I haven’t posted up many things here. I fell into the thinking that if something is on YouTube why should I post it. I realize now that knowing something is possible has value. There are a ton of things on YouTube that I don’t know are even possible and I wouldn’t bother to search.

So here we are. Very low cost aluminum repair. Easy. Low barrier of entry. A lot of money saving potential. I used only one inch of one of the seven or so rods in the pack.

This poor man’s “welding” has some caveats. It isn’t as strong as welding. It has a low melting temperature. Superior to glue, but it will melt at a lower temperature than true aluminum welding or brazing.

I think of youtube [searches] as context-free knowledge (unknown knowns). Even if I knew about aluminum welding (which I didn't), it might not have occurred to me to use it in a particular situation whereas someone with contextual knowledge would easily be able to apply it because they know both the appropriate solution method and where to apply it.

For example, I'm capable of clicking on a link and picking up the linked aluminum rods at harbor freight. However, if you were to suggest just "picking up some aluminum welding rods", I would be stymied thinking that there's probably 10 different kinds and do I need to go to a specialist dealer or such. Basically, it's a situation of knowing so little that one does not know what is important. Hence, sourcing [the stuff] needs to be completely context-free.
