Been toying with making one of these myself. Mostly to remove rust on objects without me needing to sand them. Only downside I see to tumblers is the medium you need to buy to put in it.
I had to laugh at this one. Pretty simple build and concept. Not so sure how practical it is but could be a good experiment to do with kids.
The author took the cooling grids off old fridges and combined a bunch together to heat up water. That “heated” water then has a coil inside a water tank to transfer the heat too. Which is a good idea since god knows what the chemicals in the original coils where.
Not so sure I would be brave enough to trust this thing. But a clever build overall
The author did a nice write up on using concrete overall for making decorations. He 3D printed the “Frame” to use to hold the concrete in its form. It looks like the mold is re-usable too.
Nice build, not so sure I would do it myself since there is a lot of work involved.
Pretty impressive one. The author provides templates so you can cut one out yourself. Or….maybe convert to cut on a CNC?
Pretty funny build. Me…I wonder if there is a way to build this so you don’t have to re-wind it.
Seems like a nice build.
OK I can relate to this one. I have used the metal from a can before to make projects, and I have put it under some heavy books for a bit to “flatten” them out. This looks like a better way to go (Iron it flat).-
