- How to build a Simple Homemade Bandsaw Mill from Old Car Wheels[the_ad id="6432"] This video shows the build of an really inexpensive homemade bandsaw mill out of old car wheels.One of the best things about this design is it’s simplicity of course, but it’s also made from salvaged and repurposed materials, which helps cut the cost of the sawmill down to an affordable level. Not everyone can afford $4000 to $5000 for a brand new portable sawmill. Building your own sawmill not only gives you that sense of satisfaction of doing it yourself, but it saves you money.Bottom line, it’s a tool you’ll use for years to come, and will more than pay for itself the first time you use it. Lumber isn’t cheap, and if you’ve got the natural resources and access to those resources, it makes the most sense to save money, time, and effort by using what you have available

- How to build a Simple Homemade OFF GRID Refrigerator from easily available materialsThis video shows the build of an OFF GRID Refrigerator from cheap and easy to find materials.This design uses both the cooling effect of evaporation, and two water cooled condenser coil's. The fridge is shown using both a water ram pump at the end, and an electric pump powered by 12 volt/solar, it only uses 8 watts an hour using electric.There is an air gap between the sheet and the wall of the fridge because the water running down the sheet wont evaporate as well and that the water temp is not as low as the evaporative temp so the water touching the cooler could increase the temps and limit some of the potential cooling. If the power goes out and the fridge doesn’t keep things cool anymore – what other options do we have? If you are trying to live off grid and have no power source – how can you keep food and certain medicines cool and usable for longer?Then this Offgrid Refrigerator is the answer.
