Below the top structure I mounted a long power outlet bar to have a convenient power location for whatever corded tool I am using at the table. Below that is the lower shelf which I built specifically to house my X-Carve CNC machine. This machine has 1000mm rails so making a dedicated cart for it would take up quite a bit of valuable floor space. The idea behind storing it on this shelf was so that I could easily slide it off and place it on the top work surface to use it. However, I haven’t actually removed it from it’s current location yet. I can use it where it is with no problems.
I love a good shop tour, but it’s super motivating to me to hear you say that you built it all in a few years on good old-fashioned hard work. About 8 years ago, I lost an office job and began working with my hands, first doing siding and windows, and now installing home media systems. It has completely changed my work ethic, and my motto now is, “If you ain’t sweating, you ain’t working.”
We cut the supports 16 in. long, but you can place the second shelf at whatever height you like. Screw the end supports to the walls at each end. Use drywall anchors if you can’t hit a stud. Then mark the position of the middle supports onto the top and bottom shelves with a square and drill 5/32-in. clearance holes through the shelves. Drive 1-5/8-in. screws through the shelf into the supports. You can apply this same concept to garage storage. See how to build double-decker garage storage shelves here.
A lot of woodworkers share their projects through their own blogs or YouTube channels. In fact, we’ve shared many of them here before, including, Woodworking for Mere Mortals, The Wood Whisperer, Matthias Wandel, April Wilkerson, Sawdust Girl, House of Wood, FixThisBuildThat, Pneumatic Addict, Build-Basic, Rogue Engineer, Her Tool Belt, and Ana White. The best YouTube woodworkers create great videos, but also provide a complete blog post with a cut list, tools, materials, and instructions.
