Hi all! In this episode I will show you several interesting ideas some of which you might like.
If you need to cut straight plastic or metal pipe, then the following tool will help you. 
Take a metric tape from a tape measure, cut 40-50 cm, evenly folding the ends together, drill two holes and tighten with small screws. 
Now you can easily draw a line along which you will make a perfectly even cut. 
If on time hard to reach place If you struggle with an open-end wrench, you lose a lot of time or patience, and if you can’t get it with a ratchet, you’ll probably need a screwdriver with a universal joint.
To do this, we need an adapter for screwdriver heads with interchangeable attachments. 
Using sandpaper or a grinder, we grind off the nozzle and screwdriver on both sides, and cut about 2.5 centimeters from a bolt of suitable size. There are two holes at both ends, we make two cuts at 90 degrees relative to each other. All we have to do is drill holes in the screwdriver with the adapter and pin them. 
Now, when unscrewing a bolt or nut in a difficult place, you will not lose liters of sweat for every millimeter passed with an open-end wrench)) 
Do you need to pour liquid into a container with a small neck? In this case, you can make a small funnel from the fuel filter. You just need to cut off the outlet part of the filter and the funnel is ready. 
You may have noticed inconveniences when changing the drill chuck, namely the teeth of the key slipping. You can upgrade it with a thick blade screwdriver.

Now you don’t have to worry about the chuck’s teeth breaking off when you change drills in a hurry, and now, thanks to the bright handle, finding the key among the heap will be easier. 
If you need to draw a circle of large diameter, and you do not have a large compass, then you need to make holes on the carpenter's square every centimeter. 
Now, having installed a drill or nail at the zero mark, you can draw a circle of the diameter we need. 
And also, after this modification, it became easier to draw longitudinal lines.
