Currently new orders for
Classic AirGraver will ship as pictured with Steve Lindsay's engraving
impressions on the body for no extra charge. Also new orders for Classic
PalmControls with a burl wood handle will include the embellished inset
disc as pictured in the butt. At a later date there may be an additional
charge, that has yet to be determined. Thank you for your patience while
waiting for your order..
The Classic™ AirGraver® is available with two pistons: Standard stainless piston and
a Tungsten Dead Blow™
piston. The chart bellow illustrates the speed ranges of the tool for when it is set at a short stroke, and for when it is set at the longest stroke.
Tungsten Dead Blow™
The stroke adjustment of the
Classic™ AirGraver® makes the tool perform like numerous handpieces in one.
The Classic AirGraver's length of stroke adjustment
provides a virtual multitude of handpieces in one tool. At any given
stroke length setting (determined by the adjustment ring on the barrel of the tool), the power is varied with air pressure from the foot control or
(.05psi to 80psi). The absence of an internal spring means uniform performance throughout the range, with no “sweet spots” or “dead spots”. The full range of
power and speed is "sweet" throughout, due to the internal automatic balancing of air pressure on both the impact and return strokes.
An advantage to the AirGraver design is the speed at which it can move a graver physically through
the metal when desired. The throttle range is possible because the tool's speed and power work together. If the tool would only increase in power but not
with speed, the result will be more broken points and staggered stair cut marks in the cuts. Increasing impact speed and power together will deliver an
improved, wide range of throttle speeds. An experienced engraver can increase their productivity significantly.
The AirGraver's delicate impacts gives the user ideal control. The
AirGraver® system requires air consumption of 0.1 to 0.3 CFM at full throttle, allowing the use
of smaller air compressors.
