I did it all myself, the wood is only to spacer the drawer slide out to be even. wine coolers taper at the back. Mine is 1/2 wider at the front I actually used 1/2 aluminum bar forced into the shelf slot after pre drilling then 1/2 screw in the rear and 3/4 for the front. Holds very tight it took me a while to figure it out I searched everywhere and could find nothing like it, but I knew I didn't want a drawer that could fall out.I can just imagine a drunk buddy dropping a drawer! The cedar was 118 slides about 80 and it took some time but ended up costing about the same as buying from a bullet but ultimately this is my design and I can say I built it, and I do everything myself I get a certain satisfaction from it haha my wife loves it bc I build her furniture and do all our remodelling
