I broke out my N95 respirator and my safety goggles today and went outside to do the final rough-in of the first fat doll’s neck with my Dremel. I started off with a cutting disc, which was not a good idea. Then I ran out, bought some deburring bits and used them. I doubt they should be used for my purposes, but they work, so :p.
Here’s Isabel on the fat body after I reduced the height of the neck and tapered it further. Now I just have to sand to reduce the most egregious gouges. Woo hoo!
