(24) Clearly explain, with sketches if necessary, how sheet-metal window caps are attached to brick walls.
(25) Mention some of the most important points to be considered in the construction of sheet-metal chimney caps.
(27) Describe the slip-tube method of connecting box-gutter outlets to leader pipes. Explain its advantages over the common method.
(29) (a) How can you tell the difference between hot-rolled and cold-rolled copper? What parts of sheet-metal work are they respectively adapted for? Give reasons. (b) What fluxes are best adapted for soldering tinned copper? (c) Which fluxes for plain copper?
(30) (a) Describe crimped sheet metal and state the benefit derived from crimping. (b) Distinguish between crimped and corrugated sheet metal.
(31) Clearly describe how a sheet-metal cornice may be securely erected against a brick wall (a) when the wall is being built; (b) after the wall is built.
(32) Clearly and briefly describe a lap joint in cornice work.
(33) Under what circumstances is it advisable to use cast-iron lookouts? Give your reasons.
(35) Clearly describe how sheet-metal balustrades are erected. What must be considered when the deck of the cornice has a pitch back towards the balustrade?
(36) Draw a section through a parapet gutter and explain the different parts. Counterflash the gutter.
(37) What provision should be made when leaders are allowed to discharge into clean-water cisterns? Give reasons.
(38) Clearly explain, or show by sketch, a good method of attaching sheet-metal crestings so that all nail heads will be covered.
(39) What provision should be made to prevent moisture from forming on the under side of a sheet-metal roof covering?
(40) (a) Describe corrugated sheet iron and state the class of work for which it is especially adapted. (b) How should the sheets be fastened against plain vertical surfaces? Describe the joints.
(41) What trouble is liable to occur when a cornice has water pockets? How can the difficulty be prevented?
