In a previous article I told my readers about the possibility of restoring fittings, polypropylene, under its urgent needs. I collapsed on a barrage of criticism, why do it if the recoverable material is worth a penny, - "Well, you rogue" - were full of comments the general meaning. Remember, drill pipe parts made of plastic is used as a last resort. When because of one wrong soldering have to stop work completely or throw all the "knot."
Today, rogue, according to some, will tell you how to make chips of polypropylene. At the end of the article will VIDEOBONUS. Look necessarily.
To make the drill, we need a pen on wood, they drill holes in the round lumber. Podshamaniv bit over it, we will make a drill for plastic.
I used to reface the drill in a semicircular shape - Photo 2, was obtained from this torn chips, which eventually could get into the pipe and clog the plumbing. I managed to get the chip which has a long strukturu- photo 3. To do this, we sharpen drill 90 degrees.
As a result, we get chips perfectly smooth and long. As in the lathe. Enjoy the process of drilling in slow video.
Super slow chips shooting mode (960 shots in give me a sec)
