I am slowly making progress on painting and priming. I might have to let go of perfection and decide what is 'good enough' or I may never finish the build. :)
Besides the painting, though, I learned a new skill today - vacuum forming! I could definitely have just pasted a curved face shield piece inside of the helmet for lenses but I thought it'd be fun to try my hand at vacuum forming.
I considered making my own, but I found this one from Etsy that was very inexpensive, even with shipping from Spain. https://www.etsy.com/listing/4452485131/vacuum-forming-machine-a4-vacuum-former
The files I have come with a flat lens stencil as well as a 3D vacuum forming shape. However, it's not really designed for vacuumforming since it's the exact shape of the lens. So I first copied and pasted the lens shape a bunch of times in tinkercad and cut the bottom flat to fill out the inside of the lens, and printed it. I printed the lens itself upright for better quality:
It still wasn't exactly what I wanted for vacuum forming, though, because there wasn't really going to be a way to attach the lens to the helmet itself since there's no flashing. So I used some EVA foam to build out the buck and made it slightly shorter than the lens so that when I pulled it, I'd have an edge that was inset that I could use to attach the lens to the helmet.
I went to Goodwill this morning and found a cheap toaster oven which thankfully still worked, and coincidentally exactly fit the frame for the plastic that came with the vacuum former. The plastic itself I ordered from McMaster-Carr.
Here is the video from my first ever pull, which worked surprisingly well: https://photos.app.goo.gl/BhXqtgQBVicZDv7eA
However, the protective plastic melted against the EVA foam, so I pulled it again. The second time I removed the bottom plastic so it didn't stick to the buck, but the wrinkle pattern from the top layer of protected plastic caused defects on the lens, so I pulled it a third time, this time with both sides of the protective plastic removed.
Third time's a charm!
I am planning on dying the lens to darken it.
