Looks like commercially done in some factory where all kinds of machines and equipment is available. And I mean it in a good sense! Just doesn't look "make shift" or "hand made" at all!!!! This is one of those times when I wish I was born male, with stronger physique, then learning all kinds of handiwork would make more sense. Well, I should be grateful for my other skills and many of them... Still..., I'd love to be able to build something like that! You could keep that in your living room!!!
Hey. There are lots of ladies with some serious building skills. Don't sell yourself short. Just like any man, you will make mistakes at first and learn as you go. I can guarantee this is not the first enclosure Mark has built.
