Centering ruler

Post by SteveM »

Here's an interesting tool:

How many times have you put your ruler on something and had to do the mental math to figure how much up and down to go to get equidistant points from the center?

The scale on the end is nice when you have to keep the ruler square to a surface, or you don't have the room to drop the ruler in from the top.

Great. Now I have to add ANOTHER tool to my list of "I have to make one of those" :-)

That works when you have parallel sides, but not when the sides are not parallel, nor when you don't have access to the sides.

But it's much more convenient than a ruler in those cases where it can be used.

If you have a pair of stair gages (who doesn't?)...

you can mount them on your ruler at points equidistant from the center and quickly assemble something similar to what I made.

It was said tongue-in-cheek. Most folks don't know what they are and even fewer have a set. It speaks to my tool obsession that I have two sets. :)

A typical conversation when a friend needs something fixed goes like this:

"Do you have"
"Yes, I have two"

We old school drafters used to split the distance between two lines by laying a scale at an angle with a whole number over each line. Then it was easy to mark of halves, thirds, quarters, etc.

I remember where someone needed to divide a space into a set number of roughly equal points, and they took the waistband from underwear, marked off inches on it and stretched it out across the space.
