options for an air-abrasive system for overseas field work. The main
application will be removing the closely-adhered layers of sediment from
the surface of lithics and fossils.<br>
<br>
Does anyone have experience of any kind of portable air abrasive system
or other set-up for this sort of application which might be suitable to
take on an international flight from the UK to Tanzania? Ideally the
pressure should be be adjustable between c. 40 and 80 psi and the system
should be capable of firing 29 micron aluminium oxide powder. <br>
<br>
The only option identified so far is a geological preparation 'air
abrasive blaster' supplied by UK GE, which would require a compressor to
be purchased on site but could be transported on a plane. If anyone has
experience with the UK GE model or any other solution, we would be very
grateful for your comments. <br>
