How to Make a Snorricam

Step 3 Building the Shoulder

Scribe a line 1.5" into a piece of 3/4" ply. Take your compass and make a 4" radius semicircle starting from the line (Picture 2). Draw a 3" radius semicircle (Picture 3). Next, draw lines coming out of the center of the semicircle. I had my lines be 22.5 degrees apart, meaning there are lines at 90 degrees, 45 degrees in both directions, lines in between those, and lines 22.5 degrees further than 45 (Picture 4). I decided not to put lines at 0 and 180 degrees.

This next portion i did slightly in reverse. I built the lower arm first, then used the hole in that to drill the holes in the shoulder, ensuring that the holes would line up perfectly. If you feel confident in your precision drilling, continue reading. If you want to go the way i did, drill the center hole and go onto the next step, then return to this step to finish the shoulder.

Drill holes at the intersections of the rays and the 3" radius, as well as the center (Picture 5). Use whatever size bit you want to fit the hardware you're using. I used 5/16" for the radial holes and 1/4" for the center. Now cut along the 4" radius line and cut straight out of the board (Picture 6). Next, cut out 2 right triangles from 3/4" ply. The short sides should be 3" long. screw them into the piece you just cut out 2" from each end of it (Picture 7). Next, screw the triangles and the shoulder piece into the chest plate 1 inch from the top with the shoulder piece centered (Picture 8).
