Defence & Freedom has posted a collection of YouTube videos about Gun Drilling. Gun Drilling is a process that allows long but straight small diameter holes to be drilled into metals. It was originally developed to drill out gun barrels, but now has many industrial uses.
I founded TFB in 2007 and over 10 years worked tirelessly, with the help of my team, to build it up into the largest gun blog online. I retired as Editor in Chief in 2017. During my decade at TFB I was fortunate to work with the most amazing talented writers and genuinely good people!
