Wanted to add a railroad cart coffee table for my playroom and didn't see anything I liked on the net or that was reasonable in price, so I decided to build my own. For the top, I could have just fit a few boards together and used cleats to hold them together, but Lowes sells large planks in different sizes for less than the cost of stick building the top, so I bought a 3/4" thick pine plank that is 48" long and 16" wide. When I add the thickness of the 1 X 6 side panels on each side, the overall width will be 17 3/4", which is the right size for the location the cart will be located in. The total cost should come in right around $125.00, excluding the cost of paints, stains and finishes which I already have; with the cost of the wheels being the highest.
I wanted the "look" of real boards for the top of the cart, so I routed out a few lines with an 1/8" bit set to a 1/4" depth to simulate the look of real boards for the top. I then cut and assembled the sides and ends to the top as one big box with glue and screws set below height so no screw heads would show.
I added a support at each end underneath and then inserted an additional support near each end that lines up with the mounting holes for the 8" diameter vintage-looking caster wheels that I ordered on-line. I'm in the process of painting and weathering those.
I filled the screw holes with wood filler and then sanded everything smooth.
Next step will be staining, finishing and antiquing the top and sides.
