 NOVEMBER/DECEMBER 1993Deep in the marrow of West Oakland, in the industrial desert of the abandoned Phoenix Iron Works, under the derelict scaffolding of warship craze and the flapping of pigeons and the falling of feathers, in inches of soot and clouds of green gasses, lit by shafts of light piercing dusted air from a thousand windows vibrant red from the setting west, among miles of steel and acres of concrete, the table seems simple, small, insignificant. In this gloom of forgotten machinery, under wires which haven''t breathed electricity in years, there''s the sense--not so much that beauty will one day be guest to the table--but that the table is already guest to great beauty. The Chicago Pneumatic Air Scribe is a bit noisy and also produces quite a bit of dust and grit as it disintegrates the rock matrix, making both a dust mask and ear protectors necessary when the unit is in use outside a dust-collecting chamber. A silencer that fits snugly around the hand-held unit is not available from the manufacturers but can easily be made with a few common household tools. By cutting a piece of metal tubing to the length of the air scribe''s handpiece and notching one end so that it can be crimped to conform to the tapered bit end of the tool, a very simple noise insulator is produced. A foam rubber plug inserted in the bit end forms a snug fit. The only disadvantage to this noise protection is that the natural stream of air emitted from the tool end is blocked, and dust is not readily blown off the working surface. Likely some innovative tinkerer will soon solve this problem. Simple ear plugs or muffs are adequate to help provide hearing protection. poulinchainsawsgasmix Another minor problem with the air scribes is the absolute necessity of lubrication. Producing an effective reciprocal motion to any tool involves very complex valves and close-fitting parts. This is especially true when the tool is designed to be very small. Depending on the duration of use, an air scribe must be oiled from once to several times per day. This involves shutting down the system, dismantling the air supply, and inserting several drops of high-quality air-tool oil. In-line oiling systems are available that can make this process far simpler. Additionally, regularly flushing the unit with oil will eliminate microscopic particles of metal and grit and will greatly extend the life of your air scribe. Sandblasting Another interesting tool is the Strap Master from Shaw Aero Development Co. If you do a lot of pipe hanging using metal strap, this is the hand poulinchainsawsgasmix tool for you. It cuts, punches holes in, twists and bends steel strapping with no special setting up or configuring.The Flushworks Mobile from Cliplight Manufacturing is truly unique. New regulations on how we use refrigerants make it more difficult to clean up a compressor burnout, so I was happy to see this very practical air conditioner flush and purge machine. You connect it to a contaminated system and turn it on. The advertising reads: "(Our) solvent thoroughly poulinchainsawsgasmix cleans and leaves no residue in the system when used with the Cliplight Flushworks machine." Looking for a chainsaw for sale?
