coinciding with the upper and outer edges of the thin piece on 

 each side of the circle. Place the other thin piece on top in its 

 place, and secure the whole by five veneering pins on each side, 

 and on each face (twenty in all) in the positions shown. 



When this is finished, a strip 8" x J" x |" from the cigar box 

 material is glued into the slot left along the base, and similarly 

 secured. The whole is allowed to stand in a warm place for twenty- 

 four hours, and then well glass-papered, stained, and varnished, or 

 French-polished the latter is to be preferred. 



To complete the cell it is only necessary to squeeze the I.R. 

 tubing between the two glass plates in the manner indicated in the 

 diagram, and to slip these plates into the frame already prepared. 

 On releasing the pressure, the I.R. tubing will expand, and press 

 the plates tightly against the framework, making a perfectly water- 

 tight cell, which has the great advantage of being easily cleaned 

 on the inside. 



EXERCISE 4. A teak box to hold 50 lantern slides. 



Materials required: Teak, 11" x 7" x ", 8" x 9" x " ; i 

 pair brass butt hinges, i" x ", and screws ; i hook (brass) ; 

 i countersunk and i roundhead screw for above, veneering pins or 

 \" oval brads ; 6 brass " screws (countersunk heads). 



Tools required: Hammer, tenon saw, marking gauge, bevel, 

 trysquare, plane, glass-paper. 



Method: Saw the larger piece of teak down the middle, and 

 plane each piece to n" x 3$" x ". Saw the second piece after 

 planing to give one piece 8" x 4" x ", and the other 8" x 4j" x J" 

 when finished. 



The following pieces can now be obtained 



two 4i" x 3 " x " (ends), 

 two 6i" x 3" x " (sides), 

 one 7" x 4" x J" (bottom), 

 one 6i" x 4^" x i" (top). 



Scribe the two ends and sides of each piece " from the ends 

 and parallel to them, by means of the marking gauge, and on the 

 two 6^" pieces scribe the three dovetails as shown in Fig. 20, 

 which gives a wide dovetail at the top. The shaded portions are 

 then removed, by sawing inside the line down to the scribing 

 line, and then removing the surplus wood with a chisel, taking 

 care not to start too near the scribing line. Proceed similarly 

 at each end of the two 6^" pieces. Then place one of the two
