This is a very simple and easy project to do, but very useful for our carpentry workshop. I no longer have a compass in the workshop, since when I had one it did not go very well (I think I need to go making cabinets to store the hand-carpentry tools in the workshop), so when I need to draw a circle many times I look for something with more or less the desired diameter. And only if necessary do I go into the house to find the compass.
(Review: Well now I have a rod compass home.)
The most common may be to need something with which to draw large circles, for which a rod compass is very useful. But with that type of compass, the one with rods, it is not easy to paint the smallest circles, so it is worth manufacturing both models to be able to draw all the circles we need. In the translated article you will find the video with subtitles in Spanish where you can see how John makes the compass, as well as a PDF file with the measurements that can be downloaded in print. The materials needed to make this small compact compass are very basic and you will probably have almost all of them in your carpentry workshops. The only thing a little special is the two-component epoxy adhesive, but if you do not have this type of adhesive, I already tell you that it is also something very useful to have and easy to find in hardware stores or DIY centers.
In the video that you have in the article on his website, he explains step by step how to make this wooden compass from the template printed on paper. He uses his band saw, and the disc sander, but a project like this we can do with a marquetry saw, a wooden block with the sandpaper wrapped around it and a hand drill.
You have the link to the article in Spanish about this small compact compass by John Heisz in the tab woodworking projects of this blog and there go to translations of I Buildt It (number 3).
