That thing looks awesome! I know this is kind of an open ended question, but what's your technique for getting such a uniform bead? I've found that once I get my machine set, a push/pull motion (2 steps forward, 1 step back) will get me something similar.
I like to run in circles. Sometimes I push and sometimes I pull. I pull the left side truss and pulled the right side. I like the right truss better
