Is this a good tool for fossil preparation?

My opinion is that such a rotary tool is an essential device in a preparator's tool box.  These tools come in all sorts of configurations, of course.

 

This tool is being offered without the most useful bit, in my experience -- stainless steel brushes.  But, these are readily available.  Silicone caulk cuts down on the fly-away brush wires in use -- always use eye protection.

I'd love to have one of these to supplement my pins.:)

 I have a foredom with all those tools and more, but rarely use it.   It really depends on what you plan to work on?

Same with me. I have a proxxon, but sometimes I even forget that I have the thing. Don't really need it for ammonites and that's mostly what I do.

Great tip. Wouldn't have thought of that great hack.

 

 

Cheers.

You just squirt it around the spindle shaft where the bristles attach?

I had a brass wire one and it shot out so many bristles everywhere I quite using it. I did have eye protection, but the rest of my face and upper torso wasn't so lucky.

This sounds like a great idea!

I massage with fingertips a smallish dab of silicone caulk into the bristles for maximum coverage.  The cured caulk leaves no mark or residue on the fossil.

I'm in this camp also. I have a pneumatic rotary tool that I use so infrequently that I'm actually unsure of where it is right now. :D

 

Air scribes, micro-abrasion, and acid are my typical prep methods with a heavy tendency towards scribes.

I use mine for sharpening dental picks and carbide rods.  I also use it for cutting off excess rock but only with small amounts of soft rock.  Rarely for actually removing rock from near the specimen.

Wow! Awesome idea. I go through hundreds of these and I am always pulling pieces of wire out of my skin. Thanks for the tip.

Yup. Best fossil prep hack I've seen in quite a while. :)

 

 

Cheers.

I’ve used my Dremel with the flex shaft on multiple trilobites to get the majority of the matrix out of the way and I’ve buffed some with a buffing pad as well. It’s quite handy for other around the house projects.
