Adjustable Molds and Liners.
Figure 38 shows an adjustable mold and two liners. These molds are made in three sizes for each body, No. 14, No. 24 and No. 30, and cost $30 each.
No. 14 will take liners to cast any length of line from 14 ems down as short as may be desired. No. 24 will take liners to cast any length from 24 ems to 7 ems, both inclusive. No. 30 will take liners to cast any length of line from 30 ems to 13 ems, both inclusive.
These liners cost $1.50, and are interchangeable for any size mold of the same body. For instance, a No. 2 minion liner will give 12 ems in a No. 14 mold, 22 ems in a No. 24 mold, and 28 ems in a No. 30 mold. This, of course, would apply to any size liner.

The Space Bands.
Both sides of the spaceband slide 1 and 2 should measure the same at top and bottom, but side 1 should never be thicker than side 2. On the other hand, if side 2 be .001 thicker it will insure a better lockup of the matrices.
