[R-390] (no subject)

[Jim Brannigan]

My station shelves are 3/4 inch birch veneer plywood, 12 inches deep .  The
entire assembly is a large box that sits on top of a 7 foot operating table.
All the joints are rabbitted, screwed and glued. 1X2's, on edge are used to
support the long edge of the shelves.   Molding was applied to all ends and
it is finished with stain and polyurethane.

 At one end I built a rack "box" for the R-390A, CV-591 and a few small
pieces.  3/4 inch angle iron is recessed in the vertical sides of the rack
box.  The angle iron is drilled and tapped for standard rack screws.  The
R-390A sits on the bottom and it is "shimmed" level with wood spacers
covered with flat aluminum stock.  The back is open.  The shack is air
conditioned during the summer and I never saw the need to install fans.

The rest of the shelves are used for HF and VHF equipment.
