UNDERWATER GRINDER

 

Pneumatic grinders are utilized by underwater welders, propeller/hull cleaners and boat recovery crews. The common tool used by underwater welders to clean welds is a metal hammer with a small pick attachment. A grinder will make fast work of rough welds and will also function as a surface cleaning tool for under water boat cleaners.

When a pneumatic tool is used at depths below 30 feet, the exhaust must run to the surface otherwise the tool will not function. The air from the compressor is not strong enough to overcome the water pressure at those depths. Since a secondary hose needs to run to the surface, the maneuverability of the grinder becomes quite restricted.

The Goals that have been in place during this project are:

1. To develop a system of in which to operate a pneumatic tool at depths ¬†more than 30′.

2. To minimize the size and weight of the current pneumatic tools.

3. Improve visual and tactile sensory in low level lighting conditions.
