Just like the eyes that let light into the body, the window lets light into the shop.
My shop is a "work in progress". Today I decided that I would take the time to install a window that I salvaged from a friend last year. This spot had a window in it originally but when I put a concrete footing under the exterior walls last year, I removed it. It was in really poor shape, it had gaps and cracked glass... not worth the keeping. I covered the opening and hoped to put some glass back in there at some point. When I came across the window that my friend was going to dump, I snatched it up and stored it until the right time. Today was just that sort of time.
My shop is nothing fancy, it is 50-60 years old and not really built to last this long. Ideally I would have liked to tear it down and start over, but it takes money to do that, something that I don't have extra wheelbarrels full of, so I make do with what I have.
The end result isn't something that you would see published in FineHomebuilding, but it is a HUGE improvement to what was there originally and what I had patched up.
Here it is before and after some time and effort. Much improved... I think.
Now all I need is some caulk and paint!
