As expected the right side did go much faster than the left side. I've made a small mistake, I was match drilling a hole using the 12 inch drill and I guess I let the drill bit move and enlarged the hole so I had to enlarge it from #40 to #30. Other than that, the process did go smoothly.
I'm now in the not so fun step of deburring all holes in the entire skeleton + skins. Honestly this is what took most of the my time during this work session.
