Underwater Drill?

[GDawson]

Is there anything like an underwater drill? I'd like to add a gorgonian to a piece of base rock that can't be taken out without major demolition. Gluing it to another rock and then gluing it to the base rock just won't look right where I want to put it.

Not sure if this would work but it would be cheaper than a true underwater drill.

I've heard of people using a dremel with the Flex Shaft.

Extended drill bit and cordless drill?

You can make your own bits by silver brazing a regular one to a piece of steel rod, even.

Flex shaft could be ok, but you'd have to clean out the saltwater and dry it really well.

yeah I couldn't trust a flex shaft underwater, not only is the metallic composition of it a mystery, the fact they DO use lubricants scares the bageezus out of me. Plus even if its stainless I can see that thing rusting to the point of not working after a few uses

Well shit I have a few of these gems I could sell.. I think they're a little too vintage for 99 cents though

Try a phillips head screwdriver. If the rock's too hard, get a cheap hand auger.

Mike hits on what i was going to say... I have used the extensions, you just need to remove all the lubricant. I soaked my in RODI afterwords then use an air compressor to dry it off. Worked awesome.

How big does the hole have to be? Depending on what type of rock it is (dead coral?) and how big, you can do a lot with a metal skewer and some elbow grease, or as has been suggested, a screwdriver.

Even if you want the gorgonian on the base rock, it may be a better solution to mount it to a small piece of rock that would not be noticeable when glued to the base rock and save yourself the trouble.. worked for me a few times if the rock is matched/fit well.

Already done Vic....used an ice pick and elbow grease.
