Especially it can be used without problems. Since it screws, one screw is cut out with a grinder, the pin is pulled out and the screw is stopped. It's not a problem because the price is cheap but a bit cumbersome.
Although it was meant for welding, if you can process and remove the part of the bar, you can also screw and machine it. ※ Processing is self-responsibility to the last. Although the price is cheap, making is solid and very satisfied.
The thing with the same shape screw attachment (other manufacturer) is about 4 times the price, so I gave up and bought it with the intention of using additional screw mounting holes for this. Anyway it is cheap and good. Process it to remove the stick with a sander, add a mounting hole with a drill
