The rack is constructed of hard wood throughout, and as each piece is made, it should be sandpapered and varnished or otherwise finished. The plan view is shown in Fig. 1; the construction of an arm, in Fig. 2; and the pin, in Fig. 3.
Ill: Any Number of Arms Up to Its Limit may be Used at a Time
The base is 7/8in. thick and of the dimensions shown in Fig 4. The projection on each side, measuring 6 1/2 in. long and 1 in. wide, is made separately and glued to the main part after dressing and beveling the edges.
The shelf consists of material 2 in. thick and made in a semicircular form on a radius of 5% in. On this arc. lay off chords, as shown in Fig. 1; the first ones on each side being one-half the length of the others. Carefully square up the edges for appearance. To lay off the post holes, scribe an arc of a circle on a 4 7/8-in. radius. Start at the edge on this arc and lay off eight chords of equal lengths, and bore 1/2- in. in. holes on the marks.
The posts are turned up, as shown by the detail, Fig. 3. This will require seven posts and two half posts. The half posts are secured to the base with small brads. The round part at the end is turned slightly tapering, so as to make a tight fit in the hole of the shelf. After stringing the posts on a piece of brass wire, Vis in. in diameter, and bending it in the proper shape, the posts are glued in the holes.
A T-shaped slot with a long top and a short leg is cut out with a scroll saw in one end of each arm. Make sure to have each slot exactly 1/2 in. from the upper side of each arm. All edges should be well rounded to prevent tearing of the clothes.
Make a semicircular platform for the arms to bear upon when extended. This may be either half of a turned disk or built up in the three segments, each fastened with screws to the base. If the brass wire is exactly 1 in. from the shelf and the thickness of the wood between the T-slot and the upper edge of the arm 1/2 in., the thickness of the platform should be slightly under 1/2 in. to make the arms rest horizontally when they are extended.
The shelf is fastened to the base with three or four 2-in. screws, and the ends of the brass wire are run through holes in the base and clinched on the back side. The rack may be fastened in place on the kitchen wall with two large wood screws, or, if the wall is brick, with expansion bolts. The fastening in either case must be secure to hold the heavy weight of wet clothes. - Contributed by D. A. Price, Wilmington, Del.
