#DrPepperovsky #restoration #abandoned #oldstuff #Andronyaworkshop #retro #rennovation #Rusty #repairing I welcome everyone to my channel. I offer to your attention the restoration and bringing into full working condition of an old but quite good drill. The latter attracted me to the possibility of using drills with a conical fit. A very good thing in any workshop. In this video, for the first time, I used the technique of blackening metal with the help of copper sulphate. I admit that my impressions are not unambiguous about this technology. If you are interested in my practical experience, ask in the comments. I will gladly share my impressions with you
