Based on FatBobK2's design.
This was based on FatBob2Ks great design. I took iut the Xs used 4x4 legs and 2x6s fir the bottom shelf. I also put a furring strip around the edges to hide the end grain and add some surface area. I sanded starting with 89 grit, then 120 and finishing with 150. For stain I used a rag to rub on General Finishes Java Gel Stain for 2 coats. it's really forgiving on bare wood and you don't need conditioner. I sealed everything with Minwax satin poly wipe-on and did three coats.
