Metal cutter from an angle grinder
While I was doing a vise recently, I noticed that my cutting line was not straight. After putting two elements together, it turned out that there was a gap and then they had to be filled with a weld. So without thinking long, I decided that as soon as I finished the vice, I would start building a metal cutter.
As the budget for this project was quite limited, instead of combining with an engine, septic tanks and belts, I decided to use an angle grinder, which was used once a year anyway. The grinder mounting was made of three pieces of a flat bar in which I drilled holes for the mounting screws. If necessary, the grinder can be dismantled by unscrewing three screws.
The arm is a rectangular profile with a 20mm diameter shaft, placed in two self-aligning bearings.
The top and legs are made of 30mm profiles.
The support of the cut element is an angle that I carved for half a day to get a given shape.
The clamp is a piece of the profile shot through with a screw which was also shot with a piece of threaded rod.
In order for the grinder not to fall, I used a gas cylinder found on the scrap metal.
As for the costs, they are negligible.
Scrap profiles and flat bars PLN 1.50 per kilogram.
I had a 20mm shaft at home.
The self-aligning bearings lay in the shed.
So adding everything up did not exceed PLN 50.
To sum up, the project was successful and it meets my requirements, such as cutting at an angle of 90 and 45 degrees, which can be seen in the attached construction video. I'm waiting for opinions.

Beautiful construction, each such film encourages me more and more to buy a welding machine. [Read more]
I refused to buy a welder for several years and I must be honest that those were lost years. [Read more]
@Sqerty your next interesting project. [Read more]
Congratulations on concept and execution! [Read more]
You build tools to build new tools with them :) A beautiful thing! [Read more]
So similar to such a device bought in a store. In addition, a whole day of work, so twice as much. I also wanted to build something like that, but after thinking it over, I found it a waste of money and... [Read more]
Yes, a laser sight would come in handy. As for the legs, they must be of this height, because the shield goes about 4 cm under the table top. And with this place, there is always not enough of it. [Read more]
Now that you've mastered the construction of the vice, you should do more with this project. It's something with a handle - it doesn't look very solid (jaws) ... How much lateral play do you... [Read more]
Have you not thought about moving the handle away from the grinder and changing this gas spring to an efficient one / with greater ejection force? A digital protractor would also be useful ... [Read more]
This actuator is operational. Digital Protractor .... people. Or maybe CNC right away? [Read more]
The actuator looks out of order because in some shots it looks as if the grinder was pulled downwards there. And the digital protractor ... I meant one with numbers :D I got it wrong, it's just about... [Read more]
When the grinder is lowered, the actuator is almost parallel to the arm and therefore does not raise it up. This is useful when positioning the blade where the line of the marked cut is. As for the angles,... [Read more]
A git machine as it used to be called. I built a much larger one with a belt drive, it did the job, but it was a huge rotation angle of the cut, I would have a cut under the arm, which made it easier to... [Read more]
If you just take my word for it, I'll tell you that there is no slack. It doesn't even twitch to the side, thanks to the bearings in the housing. However, I noticed that I have a slight play in... [Read more]
Hello, you can have some design dimensions [Read more]
