Did someone say kybo?

I did build my own racks, they look extremely close to those you might see at the Wine Racks America website. Though I don't have a production-grade workshop, the end results were pretty good, if I say so myself.
The work started with a 3D representation of the wine cellar to work out the dimension kinks. With the exception of the diamond bins, the bulk of the racks are individual columns tied in groups of 3, 4, 6, and 9 wide. I built the curved corners using individual columns, w/15 deg. spacers between the rear posts to give the 90 deg. 'bend', both for inside and outside radius curves. I built a jig on a 1 x 10 piece of pine, using 2 x 4 blocks between the cleats. This spacing works out for nearly every 750 ml bottle size you can imagine; only some of the large Chardonnay bottles and that damned Ch. de la Gardine CdP wont fit.
Typically, the racks are 9.5"D x 84"H, and hold eighteen (18) bottles vertically. I made two different 'case' type racks, one has six (6) horizontal shelves, the other has nine (9). I also made one double-wide diamond bin rack - about 42"H, w/a tilted display shelf on top, and a three-sided tasting table w/diamond bins for 375 mls on two sides, and the front displays large format bottles. I completed the setup w/a nice 3-1/2" crown molding on the top; that was really tough making the mitre cuts but the finished product is really quite nice.
The racking is made from #1 white pine, is unfinished, and looks fantastic; there was just too much surface to stain. I wanted to do red oak, but at the time, the budget didn't allow. The racking I built will hold in excess of 1,200 btls. I'll post some pictures; let me know if you need any further info.
FWIW, it took me approximately 8 weekends to build all of the racks, and I spent about $1,300 total on materials (more with some of the shiny new tools!

). Great project - very rewarding! Look at some of the pics
