Will need
To make a pipe cutter you will need:
- A piece of rectangular profile.
- A piece of a motorcycle chain.
- Stud with nut.
- A piece of pipe with an internal diameter equal to the diameter of the stud or slightly larger.
- A roller from a pipe cutter - you can easily buy it at a spare parts and tools store.
- Steel plates with a hole for attaching a roller.
You will also need an electrode for welding and, of course, a welding machine.
We make a pipe cutter
We assemble the assembly that will hold the cutting roller. I made such plates in advance from thick steel. You can also find them ready-made.
We paste this whole thing into the profile.
We weld on both sides.
To keep the chain at a distance from the cutting roller, we weld two steel bosses on the sides.
We weld them together.
We take a motorcycle chain and install it so that it goes around the roller
We weld one edge of the chain to the profile.
We take a pin and weld the second end of the chain to it.
Next, take a piece of pipe along the inner diameter of the stud.
And weld it to the end of the profile. Like this:
The pipe cutter is ready!
How to cut a pipe?
But first you need to fix the pipe. To do this, I will clamp it in a vice.
We put on a pipe cutter. We insert the pin into the hole and tighten the chain with a nut.
We tighten with a key creating more force.
Next, use a pipe cutter to make a circle around the pipe that we are cutting off.
Again we tighten the chain with the nut.
Let's make another turn.
This cycle is repeated until the pipe is cut. The entire cutting procedure will not take much time.
The edges turned out very smooth. You definitely can’t do this with a hacksaw.
This simple, almost pocket-sized pipe cutter can be very useful to you in life.
