  • Solvent does not remove rust.

    You degrease the part, then manually remove the rust, then clean with the solvent just before welding. Acetone or alcohol are better cleaners for weld prep than brake cleaner. These solvents are volatile enough that most of the time, the part is dry and not-flammable by the time you get your gear on and are ready to weld.

    The really damaging thing here is not the fire but if you use chlorinated brake cleaner when welding it created concentrated chlorine gas and will kill you.

    Welding produces a ton of nasty fumes and you should ALWAYS be wearing a welding rated respirator and using a fume extractor when welding, especially with flux core, galvanized, or stainless unless you want extra nasty cancer.




  • Strictly speaking here, something that could be fully repaired by the actual tools I have without just swapping for new purchased replacement parts would probably be one of my guitars. I could essentially make every piece of them from scratch if needed except maybe the pots, caps, and truss rod. I could probably repair the truss rod but making one from scratch would be tricky. If I had an acoustic guitar, that would be an easy answer.

    It might not turn out well, but I could make it playable again.

    I could repair anything on my bike, and kayak. I might be able to rebuild my snes on a component level.

    If you allow replacement parts, almost anything can be repaired of you are willing to spend enough on it.






  • Switching to something new usually inherently costs money. (Capital expense) If you are scraping by, you can’t afford another $500-$1000 a month car payment for a new car.

    The option to convert an older already paid for internal combustion vehicle basically requires another $10k minimum, not including any regulatory stuff and that would be parts cost alone, no labor. Add to that regulatory/local registration issues with the diy route and you basically bake continued demand for fossil fuels into the system.

    You can mitigate some of that by doing public transportation but you have to have a functional system AND an public that wants to use it.

    This basically means that a large portion of the population who won’t/can’t buy new EVs. Is stuck using gas vehicles until you get lower cost used EVs. The problem there is that they are expensive to repair and NOT diy friendly. Add to that battery deg and lower reliability (in general see used teslas) and people are scared to buy used EVs.

    Its a pricing problem that we have not gotten around yet. The subsidies helped but weren’t enough to get more people in. Couple that with a bad economic situation where people are holding onto their older stuff for longer and you basically get only progress on the higher income side while lower income brackets have to still use their gas vehicles which means the producers keep producing and supplying to a captive market.



  • If you work with tools or equipment in any fashion, use proper personal protective equipment and don’t skip it.

    If you work around loud noises, use real hearing protection. Hearing loss is irreversible and cumulative.

    If you work with anything that makes dust or fumes, get a resparator. You can get nasty allergies from sawdust, griding dust gives you lung cancer and a bunch of other horrible shit.

    If you work with chemicals, use gloves or whatever is required per the sds.

    Always wear eye protection, you can’t get new eyes.

    Take care of your skin, if you weld, wear real covers. Skin cancer on welders is a real thing.

    Use gloves where safe, and don’t where you are using rotating equipment, degloving is a thing. Equipment can’t tell the difference between flesh and workpieces and it doesn’t care.
