[Coral-List] Drill

[Georg Heiss]

Hi Andrew,
we used a handheld drill for several years.
The detailed description can be found in an older post on coral-list:
http://coral.aoml.noaa.gov/pipermail/coral-list/2005-January/001560.html

There are similar drills on the market, no need to buy expensive stuff.
 Maintenance: pretty simple: rinse in freshwater, run with air to dry the
tool, and apply oil generously inside the drill and on all moving parts.

The original paper is available on Research Gate:
https://www.researchgate.net/publication/230751442_Short-_and_long-term_growth_history_of_massive_Porites_sp._from_Aqaba_(Red_Sea)?ev=prf_pub

Let me know if you need more details,

Best regards,
Georg
