The first is the Engels Coach Shop in Montana. He restores or reproduces heavy horse-drawn wagons, makes wooden wheels etc. Right now he is making very heavy wheels for some spanish cannons from Puerto Rico. They shipped him a large pallet of mahogany and he is making every piece of them from scratch using hand tools and machines, many of which he designed and made himself. It is absolutely fascinating to see how he does it. Here is one of the videos in the series about installing the felloes:
He is a very straightforward guy who shows you how he does his work step by step. The accuracy he achieves with basic tools and machines is amazing to me.
The next one isn't woodworking but instead is by a retired guy in upstate New York near where I grew up whose retirement hobby is to recreate a line-powered machine shop driven by steam. Here is a video in a series about restoring a vintage steam engine.
This is a subject about which I know almost nothing but it is fascinating to me and I really look forward to his videos.
I hope you enjoy these as much as I do.
