Mixed Methods on Trilobite Roller

Recommended Posts

Kane

As I'm fairly new to prep, I thought I would "show my work." This is far from anything professional looking. I am also not using a good enough blasting medium. But it does look a bit better.

 

This is a roller found from Penn Dixie. There are still some trouble spots, and some very stubborn stuff on the glabella that just won't blast away. :( 

 

I am using a mix of approaches from needles/picks, Dremel, pliers, and air abrasion. Total time about 40 minutes.

This is where the dolomite comes in handy - a bit harder than the baking soda. 

It will remove the stubborn stuff, but be careful not to burn through the integument. ;)

The legends are true. Drywall screw and a small ball peen hammer. No magnification and no eye/lung protection. I was stupid!

I still use drywall screws on occasion. Can anyone explain why a nail bends so easily but a drywall screw does not??

The lack of eye and lung protection is the stupid part. :D

 

Screws are made from hardened steel. They have to endure significant torque when being applied. If they were anealed steel like a nail, they would twist off before they got very far in.
