MSirmon Posted October 21, 2018 Share Posted October 21, 2018 Wanting to move beyond dental picks. Right now I have a dremel I’m think about using for fossil prep but am worried about maintaining control as it tends to pull. The other options I am seeing are air scribes and abrasive blasting. Which is best? Which is the next logical step? 1 Link to comment Share on other sites More sharing options...
Kane Posted October 21, 2018 Share Posted October 21, 2018 I use both. Scribing is mostly to remove bulk matrix, and air eraser for fine detailing. 2 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

That make sense. For some reason I was caught in the trap of thinking it was one or the other but together does make more sense. I appreciate your input.

Darktooth Posted October 22, 2018 Share Posted October 22, 2018 Go ahead Mike just get both! I can't wait to see those auction wins. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...

Well there is still a little over 2 months left to butter-up Santa. As for that skeleton, well, you better slather on that butter! I like Trilo-butts and I cannot lie.

Haravex Posted October 22, 2018 Share Posted October 22, 2018 Ok for me there is two options one is great and can vouch for vaniman products being the air abrasive the second is cheaper as their are clones and also a very decent but cheap CP option being the cp9160 but you need to buy a new tip I found I guy in UK who makes them good and sharp and long just what is needed but pricing this up providing you have the air compressor will be 120gbp new or around 60 second hand plus the new tip at 35 GBP and the air abrasive unit will be coming in at around 280gbp 3 Link to comment Share on other sites More sharing options...
RJB Posted October 22, 2018 Share Posted October 22, 2018 It really depends on the fossil, but having both just opens up more doors. Good luck RB Link to comment Share on other sites More sharing options...
Vaniman Posted October 30, 2018 Share Posted October 30, 2018 Both are the best option. However, if you had to choose, and this goes against my own personal interests, I'd go with the scribe. There are some who only use a scribe for prep work and I think using it as your first tool helps to grow your fundamental prepping knowledge. The air-abrasives are just plain easy-mode and will spoil you but there is a downside to the abrasives--you do have material cost in that you have to purchase abrasive as you use it. Hope this helps! 3 Please PM me for more info on our products. Link to comment Share on other sites More sharing options...
Rob_P Posted November 1, 2018 Share Posted November 1, 2018 For sure get a scribe first, I JUST got my problast a week ago and have been pulling out previously scribe prepped material from the cabinets to give them that finished look. Also don’t skimp on a compressor either. When you do eventually get air abrasive you’ll need something that can keep up. 2 Link to comment Share on other sites More sharing options...
Vaniman Posted November 1, 2018 Share Posted November 1, 2018 Also, in case anyone needs this info.. The standard compressor requirements to power your average sandblaster is an output of 1.5cfm @90 PSI. 1 Please PM me for more info on our products.

The standard compressor requirements to power your average sandblaster is an output of 1.5cfm @90 PSI. This would not meet the minimum requirement for most air scribes though. I used to have a 1.5cfm compressor and it struggled to keep up with an Aro scribe (wouldn't come close to a CP9361 or ME9100). I was constantly having to stop and let the compressor catch up. I moved up to a 4.7cfm @ 90psi compressor wit a 21 gallon tank and it made all the difference. Now, it cycles happily regardless of the tool I'm using. 1 Regards, Kris Global Paleo Services, LLC https://globalpaleoservices.com http://instagram.com/globalpaleoservices http://instagram.com/kris.howe Link to comment Share on other sites More sharing options...
MSirmon Posted November 1, 2018 Author Share Posted November 1, 2018 Thank you for the info. I was about to ask about the pressure requirements: Link to comment Share on other sites More sharing options...
MSirmon Posted November 2, 2018 Author Share Posted November 2, 2018 I checked and my compressor is 4.6 CFM @110 psi so should be good. Link to comment Share on other sites More sharing options...
Rob_P Posted November 2, 2018 Share Posted November 2, 2018 What’s the capacity of the tank though? Unless you want it running 24/7 I wouldn’t go smaller that a 25-30 gallon personally. Link to comment Share on other sites More sharing options...
