What machine in your collection has its own sub-collection of reproducers, and how many are there?
N.B.:
Cast iron makes a poor bullet deflector - it's too brittle, and, in thin plates, such as a phonograph bedplate, will simply break out a chunk where the bullet strikes, and crack the surrounding material. The 'spall' would become a secondary projectile, capable of damaging anything (or anyone) beyond the breakout, not to mention the bullet itself. I did considerable testing of various handgun calibers against old auto engine blocks (of cast iron), and found that most modern calibers, particularly with fairly high initial velocities and full metal jackets, will crack or hole the thin areas of the block (water jacket passages, etc.) at reasonably short ranges. If you must depend on your DD for body armor, use the whole motor assembly, bedplate and turntable.
