Gear Show - Vintage Angle Grinder Conversion 100V to 40V

This is a vintage angle grinder from Japan. I think it is a vintage makita products. It requires 110V, while my location is 220V. It requires earth wire, while my location don’t have earth wire install. There are people died because of aluminum power tools in my country, because they know how to use it properly. There are a lot of new modern power tools available in market today, so these kinds of power tools are abandoned. For me, I can take benefit from it by modify it in to this way. It not so powerful like before, but I can use it for some purposes. Don’t test these abandoned power tools, It can cause danger! The following are cases encountered during the restoration: - Wrong soldering in Angle grinder - Corrupt wires can come in contact with the power tool body I hope you find this video useful and enjoy it!
