Picture of Drafting Machine
This is an instructable on making your own drafting machine. This is a drawing aid that mounts to any desk, and will give you a moving set of rulers that will keep to a right angle in relation to your board. It's not hard to make one, and it's a huge help for hand drafting. These can be made from any material, and since I'm going to add CNC capability to mine I used metal and I have space on the elbow piece for servo motors. I hope to post another instructable soon on how to make one of these draw or cut on its own from vector files. I made this all at the TechShop, and so can you.

Step 1:

Picture of
Get the dimensions of the board you plan to mount this to.
The length of each of your four arm bars should be an inch longer than half the diagonal length of the board. The shape of your pieces makes no difference so long as your joint holes are exactly as shown. Also, keeping the arms straight gives a wider range of motion.

I'm really excited about this project! Amazing idea with the servos too! I can't wait to see it!

I was wondering tho if you had drawings available for those of us wanting to build one as well?

PM Moran's drawings?
