Thanks, guys!
I used a Dremel "MiniMite Cordless" that I bought a couple of years ago at Wal-Mart for $20. It's one of my favorite tools for working on Rocketeer helmets. I mean, you really need patience more than horsepower to grind through a bunch of resin anyway so the MiniMite's "Hi" and "Low" settings work just fine for me.
This is what it looks like:
I tried using a flex-shaft on another Dremel but it just didn't work well for me. Flex shafts just ain't all their cracked up to be IMHO. The MiniMite is small enough that you can work on the eyes and mouth really easily - and to a slightly lesser extent the air vents.
Other than that, you've just got to have a steady hand and patience. Doing the eyes is hard enough because you've got to try to maintain a consistent thickness all the way around the eye opening but the teeth requires about twice as much patience I think. It's not uncommon for me to have to get the bondo out and patch a small spot here or there on the teeth that I got too thin by accident. It's hard to avoid since the edges are so close together. But the finished result makes a world of difference.
In that pic above, you're also seeing it after I've cleaned it up a bit so it looks a little nicer. I hate for the inside to look too rough so it's all relatively smoothed out.
Rob, can you share how you thinned out the mouth opening? When I was doing my helmet, I used a dremmel to do the eyes, luckly the mouth did not need thinning out because I would not have known how to get it in there like that.
