Interesting video Kelly, I thought I had seen all of the How things are Made series but that was a new one for me, the methods used to make the drills will not have changed for the last 100 years,using such methods the only place you can manufacture is in low wage rate countries,I also found the how plywood is made another video on your post interesting Health and safety was not a consideration. I then started watching making plywood boxes again another video on your post after watching 3 of 64 I thought I better leave it as I was going to be here all day. Thanks for posting
