"Centering" for the drilling machine

If you have a drilling machine and movable yews are standing on it, then the device for finding the middle of pipes or round timber is definitely useful. For crafts, you need a strip of steel and a piece of tube. An exact angle of exactly 90 ° is made from a strip, for this you need to connect two segments by welding.

The square is attached to the pipe, since this is a measuring tool, accuracy is required. A through hole is drilled from the edge of the pipe, into which a square is screwed.

The resulting "centralizer" works very simply. The tube is clamped into the cartridge so that the square rests on the tube clamped in the yew, then you need to align the yew observing visually the position of the measuring device.
