A collapsible reflector oven is a great addition to trip or primitive camping gear. The making of the oven utilizes some of the techniques of the Metalwork chapter, and the making of the case is similar to projects in this chapter. Both are good group projects. Sheet metal, cut to size, may be used instead of the cookie sheets used here; many individual variations are also possible. Aluminum sheets are lighter than tin and they are rust resistant, but they are more expensive.
Equipment needed for oven: egg-beater drill with metal drill or big nail and hammer; file. For cover: needle and thread; scissors or pinking shears; paper and stapler for pattern.
Materials needed for oven: 4 cookie sheets, 2 large, 2 small; the kind with edges on 4 sides is best; 2 stove bolts or threaded steel rods, 1/2" longer than sheets-2 wing nuts to fit; 6 1/2" bolts and wingnuts. For cover: cloth and string.
1. Review techniques in Metalwork chapter. Mark off a right angle on the 2 small (end) sheets, as in Figure XVI-48; bore holes as indicated, at A, B, C, D, E; D and E should be parallel to the bottom of the sheet, spaced to hold rods for cooking pan.
2. Bore holes in the top corners of sides of top sheet at A (Fig. XVI-49) to correspond to holes on side sheets; bore holes on bottom sheet at B and C to correspond to B and C holes on side sheets. The top sheet has holes only at the top (A), so that the top sheet can pivot on the A bolts, making it possible to look at the food while it is cooking, without moving oven (see dotted lines, Fig. XVI-50).
3. Assemble as in Figure XVI-51; put bolts in from inside out, with wing nuts on outside of oven. The bottom edge of the top sheet should rest on the top edge of the bottom sheet at back of oven, overlapping just a little. It may be necessary to bend edge with pliers, to make this possible.
4. Stove bolts or rods are inserted to make rack for pan; wing nuts are on outside of oven (Figs. XVI-48 D and E; and 51).
Steps to make Case I. Review techniques at beginning of this chapter, and see Leatherwork chapter, project on cases. Make a paper pattern first. Stack the pans together, with stove bolts inside top pan. Mark around the larger sheets, allowing space on ends and bottom for seams and hem, and adding flap on bottom pieces (Fig. XVI-52). Cut top piece the same size, without flap. Cut gusset piece to go around sides and bottom, as wide as depth of the stacked pans. Allow for seams. Cut out pattern, staple or pin together, and "try on"; adjust as needed.
2. Cut cloth from pattern with pinking shears or scissors. Pin together.
3. Stitch with overcast or similar stitch (see Chap. V on Leatherwork, Figs. V-22 and 30). Make hems on flap and top, using running or similar stitch.
4. Fasten flap with 2 buttonholes (see Fig. XVI-15) and wooden buttons (see Woodworking chapter); or make 2 loops of cord, and attach to toggles on case (Fig. XVI-53).
5. Make a small drawstring bag for the bolts and nuts (Fig. XVI-54) and stitch it on the outside of case below buttons. Make it big enough to hold the bolts and nuts and to slip them in and out easily.
