I'm wondering if anyone on the forum has used the Dropout filter kit for moisture removal in abrasive blasting units. The kit has two main components: a water separator / particle filter, followed by a carbon filter. I'm curious how the carbon filter might compare with the with a desiccant system using silica gel. Any experience-based evaluations or reviews would be most helpful. Best wishes.

It took a long time to find my first comco blaster, and it's been a couple years since, but I finally found another auction, 2 in fact. I wanted 1 more for a second prep station, but I couldn't pass up a good deal. So now I need to open them up, clean, and replace anything worn out. Glad I already learned how to overhaul these from my first blaster. I plan on selling one of these after I'm sure it's in good working order.

OK, since someone asked me about the prep station I am finalizing, I took took some pics today. To begin, I am working with the available space I have in my shed. I know its tight, but it fits and I'm not cramped. The only downside is that I will have to wear headphones while working. I put a lot of time, research and planning to make the most of the parts I have. For anyone thinking about taking this step, plan out EVERYTHING and price it all out, then probably add another 10% margin. I went the absolute cut-rate version of a prep station and I still have almost $1000 invested. The blast cabinet is from harbor freight. It was a pain putting together, but for the price I couldnt pass it up. If I went with a table-top model or built my own, I'd still have to build another bench and I probably would have spent more $$$$ in the long run. One of the last details yet to finish, is that I'm running the vacuum exhaust outside to prevent the chance of filling the air with micro dust. I have a weatherproof outlet cover it will feed through so that it can keep critters out when not in use. The compressor puts outs out 4GPM, but my tools only use about 1GPM so the volume is plenty adequate. I made the choice to runthe air through PEX piping after looking at all the options. The compressor feeds into the airline with a drop-leg for condensation. For the micro-blaster, I decided to go with a Vaniman Problast model. You can see a second condensation drop-leg running behind it. I didnt even install the included blast cabinet light, I read a ton reviews about how useless it was. I installed 2 LED flood lights to give plenty of illumination. I also ran a pigtail air line with a blowgun for clearing off my specimen, or view-glass, or lights, etc. I could also put on an air-scribe and switch between scribe and blaster without stopping. Using a cyclone dust management system. I dont have this mounted yet, its just mocked up at the moment. I plan to finish that tomorrow. I ran a vacuum line "Y" to the work bench as well. You can also see the switch which powers the box lights as well as a pigtail plug so I can connect the vacuum and turn it all on or off with a single switch. Dry air is very important while using scribes and blasters. This is my drier setup. Anything that gets past the 2 drop-legs, goes into 2 filters (particulate and water/oil) and then a desiccant drier. All that ends in a manifold for distribution. Adjustable vacuum hose on the work bench with a blast gate so I can select or close which ever vacuum line I need. I don't have a blast gate on the box yet. I'm going to have to fabricate a couple connections to make it work. Lastly is the work bench. Again, please excuse that its still filled with construction materials. I built the bench based on the existing remnants from the old shed I cannibalized to make this one. Annnnyway, I gave myself plenty of overhead, below, and bench top storage space. My flex-shaft dremil is ready, and I have an air line for scribe work. I plan on mounting it to a bracket to make it easier to connect to. Lastly is a lighted, magnifier for working on the finer details. A few more things left yet are sandbags for fragile items needing support (I have the sandbags, just need some clean sand), a cushioned mat for working at the blast cabinet, and a new work stool.

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 pic, so I had to screen shot the auction listing. It's the one on the far right. The seller listed it as Modocia whiteleyi.
