All the same, an amazing material is polypropylene. What is not done only from it:
Polypropylene pipes for water supply are generally an economic miracle. It is very cheap compared to metal. Easy to install, very simple.
In addition, it has amazing properties. Durable but elastic at the same time. Lightweight, easy to handle. These properties are widely used in many areas of life. Especially home-made. Home craftsmen.
Recently, in search of a boat motor, the water-motor season is close, I decided to look at AVITO. Leafing through the pages, I came across a very interesting homemade product from our favorite pipes:
In this craft, the pipe is used as a structure carrying on its "shoulders" the entire burden of the DIYer's thinking. Please note that the screw is also made by hand. And this is quite difficult to implement and time consuming.
From a different angle, we see that a gearbox from an angle grinder is used to transmit angular rotation, or, as they say in ours, from a grinder. Also an interesting idea.
And if you look at this structure in its entirety, then we will see what role is allocated to polypropylene pipes. They act as a hinge. A power take-off shaft from a 12-volt motor passes through them. Most likely borrowed from the car's stove. The pipe is used as a tiller. And also in the unfolded state it carries the load from the propeller to the boat.
Amazing pipe properties in action. For the sake of curiosity, I would buy it for 1500 rubles, but the current owner does not want to bother sending it. Alas.
I could not pass by this homemade product, I was surprised by the perseverance, skill and desire to be mobile on the water, the owner of the homemade product. I would have shaken his hand for his straight arms, forgive the tautology. It's not in vain that they say:
"Need for invention is cunning"
