Safely moving a tall
mill chimney has been accomplished several times. Chimneys which have
been caused to lean slightly through settling of the foundation may
be straightened up again by sawing out the mortar between courses of
brick at the base. A chimney 100 ft. high and 12 ft. square at the
base will be varied over 8 in. at the top by the removal of 1 in. at
the base. When you begin to fix up the mill for cold weather, don't
forget to put a steam trap in each and every steam pipe which can be
opened into the atmosphere for heating purposes. For leading steam
joints, mix the red lead or litharge with common commercial glycerine,
instead of linseed oil. Put a little carbolic acid in your glue or
paste pot. It will keep the contents sweet for a long time. Look well
to the bearings of your shafting engine and machines. Sometimes 25,
30, 40 and even 50 per cent. of your power is consumed through lack of
good oil. When you buy a water wheel, be sure to buy one small enough
to run at full gate while the stream is low during the summer months.
If you want more power than the small wheel will give, then put in two
or more wheels of various sizes. When it becomes necessary to trim a
piece of rubber, it will be found that the knife will cut much more
readily if dipped in water. When forging a chisel or other cutting
tool, never upset the end of the tool. If necessary cut it off,
but don't try to force it back into a good cutting edge. In tubular
boilers the handholes should be often opened, and all collections
removed from over the fire.
