Damage to a specimen, or to the air scribe itself, can occur in several ways. Almost always it is due to operator error. The air scribe is very powerful and quite capable of quickly boring into mineralized bone or shell--with dire consequences. The reciprocating, or in-and-out, movement of speedwayelectricdrills the tool can actually pull the bit through the specimen in a series of millisecond-long bites that can leave the operator in a panic. The secret is to completely familiarize yourself with surface texture, color, and physical properties of both the fossil and the matrix--these are unique and vary greatly between specimens. Let the machine do the work. Knowledge of texture and color lets you know when to lighten up and pull away, and, for the most part, the movement of the chisel tip without any help except guidance from the operator is sufficient to reduce matrix to a fine debris. This is perhaps the most difficult technique to learn because it is human nature to think that force from our own muscles will make the job faster. Quite the contrary, speedwayelectricdrills the application of too much pressure only ensures that your lab will be filled with an incessant whining, your speedwayelectricdrills air scribe life span will be considerably reduced, and you may snap off fairly expensive chisel bits. In addition, because air scribes are so powerful, the bit should never be used as a lever. It is the reciprocating movement of the tip of the bit that effectively breaks apart the rock matrix. Wedging the bit into the rock, twisting, or speedwayelectricdrills levering off larger chunks not only breaks chisel bits, but also rapidly transforms your air scribe into a useless paperweight. With proper care, common sense, and regular lubrication, a pneumatic air scribe will last for years and will enable you to prepare fossils from nearly any matrix. Lab technicians are also finding that air scribes enable them to develop fossils in a way never before available to them, bringing out details of specimens impossible with older, more traditional technologies.

Just look at the new Central Commodity System (CCS) for planters and air seeders. CCS bulk tanks carry up to 100 bushels of seed, and have a central location for quick bulk refilling, so you can make the most of short planting windows.Pro-Series[TM] Row-Units, available on all CCS planters, use a maintenance-free Pro-shaft[TM] drive system for smoother operation and greater reliability. Each of our new air seeders uses the unique 90 Series Opener to put the seed right where you want it, acre after acre, in heavy residue, bare beds, and everything in between.
