Introduction: DIY XXL Compass
In this Instructable, I will show you how to build your own workshop compass from leftover wood.
Step 1: Materials and Tools
Metal screw and bolt.
A carving blade.
Step 2: Design and Cut
Draw and cut the 2 arms of the compass from the wood plate (like in the photo).
The measurements for each arm are 4 cm for the top, and 2 cm the bottom and the length is around 30 cm.
Step 3: Carve and Fit
Draw a diagonal line on each arm or place them on top of each other in a diagonal way so that they ll fit inside each other and Carve them using a blade,the carving depth equal to 1/2 of the wood depth of the arms.
you can also cut them into shape using a table saw.
Step 4: The Pinpoint and the Pencil
Drill an angled hole in one of the arms, and put the screw all the way through it.
Cut a 15 cm stick of wood and drill the width of the pencil you ll be using.
For the depth, 5 cm should be enough to keep it in place.
Screw it on the other arm making sure the pin-point and the pencil along with the arms will have the same length.
Step 5: Assemble and Test
Drill a hole for the metal screw in the top part of the arms and assemble your compass.
Test it out.
P.S: if the arms are too long, they could weaken the stability of the compass.In that case, you could screw a round piece of wood ( layout in the last photo ),as a stabilizing add-on in the middle of one the arms, and a wood screw in the Second one.This will solve the problem.
