In this video I make a conch shell type horn from three layers of board. You can download the free template here. The horn I made is based on the templated printed on A4/letter sized paper, you could easily enlarge it to make bigger horns. Most of the cutting is done on the bandsaw, and with a smaller blade you might even get away without resorting to the scroll saw. Check out this easy to make horn that even looks nice. The video also incorporates a first glimpse at my multi purpose router table sled which includes a pin router attachment (which I am using for this project).
