Steam Boiler: Small Brass Shell Boiler, Screwed and Soldered (Hopkins, Model Engines and Small Boats, 1898)

A small steam boiler for model engines and boats: a brass cylinder 4 in across, closed by two brass heads tied together by a brass stay rod, its seam held by two rows of brass screws and sealed with solder. It sits in a russia-iron jacket over an alcohol lamp, with a weighted safety valve and fusible plugs that put the lamp out if the water runs low. Result: a strong little shell boiler, 6 to 12 in long to suit the engine. Source: N. M. Hopkins, Model Engines and Small Boats (1898), ch. III. Unknown: the working pressure and the valve's sizes. Picture: the book's Fig. 33.

Make the heads and stay

Cut two brass disks 4 in across and about 1/8 in thick, each with a 1/4 in hole in the centre, and true them up in the lathe. Pass a 1/4 in brass rod through both and solder it, with plenty of solder inside the heads to make them steam-tight. Screw heavy brass disks (round nuts are better than square) onto the rod ends against the heads. Set the heads 10 in apart over their outsides; about 6 in will do for a small single-acting engine, 7 in for a double engine, up to 12 in for a larger one.

Roll and screw the shell

Cut soft sheet brass at least 1/32 in thick (1/16 in for boilers over 8 in long), about 14 in long and 1/2 in longer than the heads so it overhangs 1/4 in each end. Roll it round the heads on tinner's rollers, never by hand, so it laps about 1 in. Slip it over the heads and rod and bind it tight with heavy twine. Drill two rows of holes along the lap, tap them and turn in little brass screws that go just through the under plate without projecting. Do not use iron screws: their rust pits the seams.

Solder it up

Push the heads and rod out, hold the shell in a Bunsen flame and run solder well along the seam. Push the heads back and solder them all round the edge, and screw the nuts tight: the screws and stay take the strain, the solder keeps in the steam. Drill two or three 1/4 in holes in the top and bush them with heavy brass disks soldered on. For fusible plugs, drill two 1/4 in holes near the bottom and solder them shut with little brass caps.

Fit the jacket and safety valve

Cut end supports from russia sheet iron to hold the boiler by its ends, with an opening for the alcohol lamp, and bend a russia-iron cover over it, riveted to the ends by little ears. Punch a row of small holes along the cover's lower edge to let air in for the lamp; the cover keeps in the heat and keeps draughts off the flame. Turn a small safety valve true in the lathe, grind it to its seat with emery and oil, and fit a lead weight on its bar. Not given: the valve's sizes.

Fire and set it

Fill the boiler two-thirds full, connect the engine and light the alcohol lamp under it. If the valve blows off before the engine turns over, move the weight a little farther out until the engine runs without steam escaping; well made, the valve will then blow off soon after the engine stops if the fire is left. If the water ever runs very low, the fusible plugs melt and the steam puts out the lamp. Do not try to burst a boiler to test it.
