…says the Italian renaissance astronomer Galileo Galilei to a young student as he demonstrates a pair of proportional dividers. So how do these ingenious scaling devices work? The answer is embedded in the geometry of the sectioning of a circle. Here’s an excerpt from “From Truths to Tools” (shipping now) that presents an intuitive understanding:
With a bruised right rib and something seriously wrong with my elbow today, I thought about titling this blog entry: “Burn Horse Garage, You Sputum of Satan – Ptttttth, I Hate You – Love Chris.” Instead I decided to focus on the ridiculous aspect of this project: What I will do to create my workshop.
During the last 12 months I have failed to install the new screen door for the front of our house. It’s an easy job – probably only half a day. But apparently I’d rather spend weeks mired in rebuilding concrete block walls, heaving old mattresses to their doom and ripping out 40 square yards of disgusting detritus all for a 25’ x 30’ bunker to hold a few machines and a wood pile.
For the last three years I have neglected to make and install 5’ of moulding on the stairway of our home. It’s an insanely easy bit of work. I could do it with moulding planes or a router in an hour or two. Lucy would be so happy. But no, I’d rather rip out weird tile and ceiling boards for four days straight. (Asbestos? I hope not.) All for a dark cave that is as inspiring as a Communist debriefing room.
Our house’s lamppost and doorbell haven’t worked since the Clinton Administration. The risers of our stairs need a quick coat of paint. My office walls need to be painted after a plaster repair five years ago.
I’m a horrible person. And apparently I am also a sociopath because I don’t care. Today we spent hours restoring the jambs of the Horse Garage – resetting them to their original place in 1906. We filled all the nail holes with an all-weather putty. We sanded. Scraped. Primed and painted.
Honestly, this blog entry could be entered into evidence in a divorce proceeding.
And that’s fine. I deserve it.
As long as I get to keep the shop.

My daughter Maddy reports she has fewer than 50 sets of stickers left, a set that includes the “Sharpen This” sticker that is showing up on the boxes for sharpening stones everywhere. (Wish I had thought of that.)
If you want a set of these high-quality stickers, here are the details. You can order a set of three from her etsy store here. A set is $6 delivered ($10 for international orders).
Or, for customers in the United States, you can send a $5 bill and a SASE (self-addressed stamped envelope) to by daughter Maddy at:
Stick it to the Man
P.O. Box 3284
Columbus, OH 43210
As always, this is not a money-making venture for me or Lost Art Press. All profits help Maddy through college. (Only one more college payment due!)
After this set is exhausted, we’ll be printing three new stickers. I’m working on the new designs now.

You can now purchase our limited edition “marriage mark” hats in the online store. The hats are $27, and that price includes shipping in the United States (sorry these hats are not available to international customers).
You can purchase your hat via this link. You might want to hurry as there are only 100 available.
These are hats were embroidered and stamped by Texas Heritage Woodworks, so the work is crisp and perfect. These hats are made in China by Adams. But they are the best hat we could find before getting into the $100 baseball cap territory.

We’ve just posted a new video at Crucible Tool’s blog on how to create two additional (and useful) tip shapes for your dividers. One tip is designed specifically for scribing arcs. The other is for cutting inlay or recesses.
While we show these tips on our Improved Pattern Dividers, they can be created on any pair of dividers.
Also in the short video, Raney demonstrates a down-and-dirty way to harden and temper the tips with a torch.
