Many of you may know what this simple device is and some of you may not.
It is a centering fixture or jig.
They are very easy to make and not expensive at all.
Lots of luck finding one at the Bog Box Store.
Once it is made you will find all kinds of use for it.
You can make them as large or as small as you want.
The only important thing is all three holes have to be exactly in line with each other and exactly the same distance apart.
The beauty of making this is you dont have to measuer anything as crazy as that may sound.
All you need is one block of a given length of anything.
A fence for the drill press a C clamp and a stop to clamp on the fence.
A straight pin to go in the drill press chuck.
What you will need is two pins for outside holes and what they call a transfer punch for the middle hole.
How it works.
Place anything that will fit between the two pins and rotate the fixture or jug until the pins touch the sides.
The center hole will always be in the middle.
Put the punch in and make your mark.
Here is the pictuer I drew up of one.
