A place to share practical, durable and quality made products that are made to last, with an emphasis on upcycled and sustainable products!
Guidelines:
Things that are well-made and durable (even if they won't last a lifetime) are A-Okay!
Unlike that other BIFL place, Home-made and DIY items are encouraged here, as long as some form of instruction is included in the body of the post.
Videos links are not allowed as post titles, but you may use them in a text post.
A limited amount of self-promotion is accepted, IF the item you are selling aligns with this criteria:
- The item must be made with sustainable or recycled materials.
- If electronic in some way, the item must be open-source.
- The item must be user-serviceable (if applicable).
- You cannot be a large corporation.
- The post must be clearly marked with a [Self Promotion] tag in your title.

Nah, the problem with that is then you have to spend on welding tips, gas, flux, etc.
What you really got to do is find a good lithium mine, and build a small manufactory and foundry. Also a chemist lab. Oh, and glassworks of course. Luckily quartz is easy to find. Then you can produce your own argon, oxygen, etc. maybe an iron mine as well. Those deposits of course you should make sure have enough resources to last you for life.
Spot welding is not the same thing as welding. A spot welder shorts a high discharge dc current across two electrodes to melt nickel strips to the battery terminals to connect them. It does not use gas or flux, nor does it consume the tips of the electrodes.
It is both considerably easier to learn than real welding and the equipment is considerably cheaper. I think I paid around $125 for my k weld, plus another 40 bucks for the high discharge lipo to run it and another 20 for a charger for the lipo. It is not anywhere close to real welding in complexity or cost, and you can learn in one afternoon.
