Midfinder Easy Way
For easy creation of a Tool to find the centerpoint of some Object it is important to eliminate any chance of error at build time. This instructable will show you how to build such a tool without the need of precise tool to set things up.
You Need Some Scrap Pices
You need some scrap pices. Could be wood but any other material is suitale too.
Cut Your Scrap Like Shown in the Graphics
Cut your pices. It does not matter which size. Do it to fullfill your needs. Only important thing is to cut the angled pices at once and with the shorter edge lined up. Some angle near 45° will be OK.
Glue Them Together
Now glue the two pices together. Or screw or weld or whatever.
Important: make the pices slightly ofset in height like shown in the picture.
Glue Bar to Base
Now fix the third pice to the ofset and you are done.
The trick is that the base pices form an angle with the staight edge bisecting it. So no matter which angle you choose, the bar fixed to this edge will bisect it.
Use
Simply place the object on witch the center is needed at the angled pices. Draw a line, rotate the object and draw another line. The crossing marks the center.
