This helmet I had to try get done in a lot shorter time frame than the Thomas Helm, however I had a much more accurate Pepakura file for this helmet which made my work a lot easier.... slightly easier.. maybe XD
The helmet was built up in 2 days from cardstock I bought at Staples, the inside was then coated in Sonite wax from smooth on.
I thinned down some body filler with resin and slushed it around inside the paper helmet, the wax layer kept the filler from bonding to the paper and as soon as the first layer was cured I added another few thickened layers to add strength to the piece.
I peeled the paper off of the cured piece, gave it a quick coat of primer and got to sanding !
Next I cut out the back dome piece so I could sand and shape it separately since it is meant to be a separate piece anyway. I noticed in my reference pictures that the panelling behind the ear should be thicker than the frame in front of the ear so I got to work on correcting that.
I drew out a template for the new sized back panel, this new thickness will be added the same way as the helmet was cast, using thinned filler.
Then more filling and smoothing and starting on the visor shaping.
The thickness of the edging was evened out,
and the nice straight corners I had were rounded with a glob of filler and the lid from a resin can.
The visor was then sanded and smoothed:
I designed the ear pods in Solidworks and had them made on a lathe by a friend so they came out perfect.
Once the ear pods arrived I cut out the rough panel inside the ear recess and replaced it with sheet plastic that was left over from the glove plates. The actual helmet has a detailed circuit pattern in this recess but due to time restrictions that piece will have to be retrofitted after the event. Using the grinding wheel on my dremel I cut out the grooves on the sides of the helmet and test fitted the ear pieces, the visor was then cut out so I was left with the frame piece. I left 5mm of the original visor on the frame to act as a lip for the Vacu-form visor to sit on. I can then add the 5mm back onto the original visor piece with more filler and turn it into a buck.
The frame was painted using spray paint, I spent a lot of time looking for alternatives to professional chroming because it just wasn't in my budget and I had a looming deadline. The results I got were in my opinion extremely good for a spraycan, the gold isn't a mirror finish like real chrome but is very reflective and went on like a dream, pictures don't really show the finish well but you can see the colour of the tiles under the helmet reflected in the paint.
