I finished the dust collection system in my prep station this morning so I had to put the tools to use and start practicing! In a nutshell, I LOVE AIR TOOLS!! I picked out one of my random BOBs collected over the years from the South Dakota Hell Creek fm. Typical of my digs, this one had a lot of surface CA and matrix adhering to it, but it was about as clean as I could get it by hand.. I started out by cleaning half of it with just the soda blaster. You can see in the picture that it was doing a phenomenal job. I wanted to get a pic that showed the condition before I worked over the en

About a month ago I went to Penn with two fossil buddies and they both found prone greenops. Sadly I did not find one. However both of these greenops were split between the positive and negative and probably were missing some skin as the material was quite flaky. For one of my friends this was his first ever find of a prone greenops. Prone greenops that are nicely laid out are a very rare find in the Windom shale. Most of the ones I have found from there or others that I have prepped for people are fully, partially enrolled or distorted. So to my fossil buddy this was a bit of a special find.

I have been working on making my own air abrasive unit but the pen section I created it not precise enough being made of plumbing parts. I am curious if any of you have found a somewhat affordable pen. I have only seen tip replacements and pens with the abrasive feeder. Thanks

Scientific Study on use of Air Abrasion for Fossil Prep
DeepTimeIsotopes posted a topic in Fossil Preparation
I just found this paper on air abrasion for those of us that would like to increase our knowledge and maybe adjust our techniques while using air abrasives. EDIT: SEPARATE LINK TO SOURCE https://palaeo-electronica.org/content/2018/2279-air-abrasive-fossil-preparation- 7 replies

A few weeks ago I realized it had been a few years since I fired up my little prep lab. I went through a career change and I've been super busy. Decided it's now time to take a little time for myself. So I bought a few unprepped fossils on that auction site and today I finally got to work. I started on this little gal from the Weeks formation and, of course, my air compressor decides it didn't want to come out of retirement and crapped out on me. Now I have to wait until I can get a new one, just as the fever was striking again. Oh well. Here's some pics. I forgot to take a before

I could use some help in getting a new air abrasion setup. I ordered a MicronBlaster only to find out that they have closed. Their web page works nothing else does. I now have to jump thru hoops to get my money back. I tried the HF etcher and had no luck getting it to work. Looking for something of better quality without going broke.

So I recently purchased a blast cabinet to eliminate some of the dust from abrasion. But, I don't know if I connected the shop vac properly. I connected it to the side(where there was a filter already) with duct tape. It feels like it's drawing some pressure, but it just doesn't seem right. The cabinet stays clear for me to work on fossils, but a lot of medium remains in the cabinet. Any ideas? Suggestions? Pics of your own setups?

Big difference between an airbrush and air eraser O_o
joshuajbelanger posted a topic in Fossil Preparation
I have been trying my hand at prepping for a few months now. Started with some nice air scribes, then tried air abrasion. I bought a cheap badger airbrush and threw tons of media at fossils. To me, it seemed that no matter what the pressure or sand agent, I saw absolutely no results. So, I bought a AEC and had it overnighted, hoping I was just using the wrong tool. Well, absolutely I was using the wrong tool. The moment I got the AEC up and running, I finally understood why it's called an air eraser. Slowly, but surely, the tough dolemite matrix melted away, as if it was being miraculou -
I'm just curious to see what all your pros are working with. My station is pretty much complete, I have a limited area in south tampa. I've seen a lot of the air abrasion boxes, and I'm curious, what's the point? Why not just use a full face APR, gloves, and call it a day? Anyway, SHOW ME WHAT YOU GOT!

I have been meaning to do this little experiment for some time. Normally an essentially complete trilobite from Penn Dixie in upstate New York will take me about 30 to 40 minutes to prep. Prepping one of these is relatively easy and generally gives decent results. The dark black trilo against the grey matrix always comes out nice.These trilos (eldredgeops) are about as common as I can collect and I probably have hundreds in buckets that might get prepped someday. So for the experiment I took a trilobite that was essentially complete and substantially covered with matrix. This was an extremely

Anybody used a Prep start Air abrasion unit for cleaning fossils, was looking to purchase one for my home workshop and was wondering if any of these dental units are useful for prepping fossils? Mainly the Prep start though as this is one i have an option to buy. If any one has a video of one in action that would be brilliant, or images of work they have done with one, that would be most useful. Cheers Dan
