“Why reinvent the wheel. Buy in the store ": they wrote about homemade products. But they are not on sale

Why do people make homemade products, I see three options here:

1. The device can cost a lot of money to make yourself cheaper.
2. What a person needs is not on sale at all, you have to include Kulibin.
3. There are a lot of ideas that I want to implement, and I just like to tinker.

Bag hoop

They cleaned up the garbage with their son, putting it in a bag, it was inconvenient, the edges were constantly wrapped, got an idea to make a hoop. I took a wire, and two tubes that allowed to adjust the diameter, everything took it straight out of the trash.

I found out if this is for sale, it turned out - no, there is a garbage bag hoop, price 1521 r.

Guide - circular rail

It was necessary to make an accurate cut along the mark, first I made a guide. Then he wanted to cut at any angle, attached a block to it at the end, which allowed you to set the desired angle.

It turned out to be a universal thing, you will not find this in a store.

Modified soldering iron

The device itself (600 rubles) for welding pipes, I decided to add the ability to solder wires to it, fixed a homemade crucible and that's it.

Then he made a hole in the end and cut a thread to fix the pipe welding nozzle in hard-to-reach places.

True, there is a soldering iron with a face nozzle, it is more expensive, but another idea came up.

I cut a thread on the sting and got a 600 W adjustable soldering iron (not found in the store), which can solder massive parts. Even the "hatchet" is not so powerful, like that!
