Recently, at my construction site, I hired "shabashnikov-roofers" for mounting "hip roof". I decided not to do it with my own hands, especially since it's winter in the yard. Therefore, I had to fork out and hire builders. I managed to pass the professional test
They screwed in self-tapping screws with cordless screwdrivers. But unfortunately, many people know about it, lithium ion batteries do not like the cold. And in those days, the frost fell to minus 20 ° С. To help my employees, I decided to give them a screwdriver bought in the "Traffic Light" m-not for 999 rubles. Test his stamina in a professional setting for one thing. I wrote about him earlier. Many doubted her ability to work under constant stress. And this case will finally dot the i.
They immediately received a comment that the shura has a plastic and short cord. From the frost he was ready to break. I had to lengthen it and replace it with a frost-resistant one. How did I do it? Take a look at the gallery. Scroll left (swipe).
After replacing the supply cable, he gave it to the builders, with the words: "Do what you want with it, it won't burn, it won't burn well."They were happy to test it.
On that day, they were just screwing the plates and corners onto the rafters. And the frost in the morning dropped to minus 20. The rechargeable shura didn't last long.
A couple of days later, I asked them how this screwdriver behaved. Didn't they burn it. And whether it is suitable for roofing work.
To which it became clear from a conversation with them:
Shura is rather weak, but at the same time an 80 mm screw tightens without problems into frozen, wet pine. Longer self-tapping screw, into dense wood, won't pull. It is good to use it indoors, when decorating. But not on the roof. The fact is that the wire, although I lengthened it, still complicates the work when moving along the rafters. Therefore, such a wire screwdriver can be used on the roof, but as a last resort. When the battery fellows refuse to work.
Happy New Year, friends! Health to you, in the New Year.
