No problems with the files. But it's been a few months since I did the pep work and those kinds of memories seem to have a half-life of about three drinks.
Today I finally got a few more minutes to spend on the helmet. I started by making a paper template for the visor. This is what the template looked like:
I used it to trace onto a piece of acrylic and cut out a couple of copies with the scroll saw:
Then I peeled the backing paper off of one of them and cooked it in the workshop toaster oven until it was soft and flexible:
NOTE: Acrylic has tiny pores on the surface and at normal temperature and humidity levels, these pores will have tiny bits of water vapor in them. If you heat the acrylic too fast, the water vapor will boil and expand and cause bubbling in the acrylic sheet. You can mitigate this by pre-baking the acrylic at about 120 degrees for a while. If, like me, you're too impatient for that kind of noise, you can get away with skipping that step. You just have to watch carefully and remove the acrylic piece from the oven after it's flexible and before it starts to bubble.
MORE IMPORTANT NOTE: Cooking acrylic like this releases all manner of nastyness. So if you try this at home, don't huff the fumes or you'll probably get nostril cancer or something.
Once the acrylic cutout was nice and flexible, I pulled it out of the oven and put it in place inside the helmet. Once I was happy with the positioning, I clamped the ends in place:
Then I used a paper towel to push the nose part into place without burning my delicate fingertips:

The trick here is to avoid marking up the area I'll have to see through later:
With that done, I used some cyanoacrylate adhesive (like Krazy Glue) to hold it in place:
Here's how it looks from the outside:
And a quick sith selfie:
Not bad:
I've still got some paint work to do. For now it sits on the shelf while I get working on the rest of the parts:
Stay tuned...
