Wanted to show how I keep the sand out of the lights. It's kind of crude but it's short-term.
A little about this drain in case any of you put one in. This drain doesn't have an elbow like your sink or toilet would have. It's straight down with a 90 degree angle going out the side of the garage. I don't run anything through it out on the ground that would hurt the environment. The thing about the drain is you see a piece of carpeting wrapped around a threaded rod with a couple wraps of wire around the old piece of carpeting and a big flat washer on the bottom holding the carpeting on there. This has been working for about 12 years and I never have to monkey with it. What it does is allow you to drain some water through the drain through that homemade drain stopper and if you really want to run a lot of water through it, just pull that out. The other thing it does is keeps the cold air from blowing up into the garage. It's crude but works exceptionally well. The drain cover you see laying there is duct taped to the floor so the sand won't get down into the drain.
This is the toaster oven I will use to harden the paint on the nuts and bolts after I get done rattle canning them. Salvation army..5 bucks.
