Re: Steampunk Ironman Helmet WIP - Cheek Detail Concepts
Had a break-through last night on the faceplate hinge!!!!
As noted, I've worked on double-action side hinges (like Mockle's standard IM design). I also worked up a single hinge located at the center of the forehead.
But I simply could NOT get any of these to work well. That led Digitizit and I to a bit of a brainstorming session where he brought up a 'rail' or 'sliding track' system for opening the faceplate. I tinkered with several versions of that while I was on vacation in FL this holiday, but was still far from a working model... until last night.
I had an evening off and after several frustrating hours, I finally ended up with something that looks VERY promising! :love
The idea is pretty simple... You glue a section of hard plastic tube along the inside of the helmet from the brow-ridge toward the crown of the head. You affix a 12ga. wire to the 'nose' section of the faceplate that runs up between the eyes of the faceplate and into the plastic tube (track). When you pull on the wire that extends past the track (inside the helmet), it pulls the lower part of the faceplate where the wire it attached toward the top of the helmet face opening. Since the wire/faceplate attachment is hinged, it allows the faceplace to rotate in a way that allows it to move up and back toward the top of the helmet.
The up-sides of this design is that there are almost NO impact to the head-room inside the helmet. There are also no visible parts and a very simple movement system (no double or sliding hinges). But the down side will be the tension within the system that is necessary to snap the faceplate down into it's grooved place in the 'closed' position. The wire MUST be under some pressure to keep it down in place but not enough to prevent it from pulling itself out of position and up into the 'open' position.
I also haven't worked out the control system for stabilizing the faceplate-to-wire connection through this hinged motion, but I feel like I'm very close to having a workable solution!
Here's the video of my first tests...
After this video was taken, I did extend the movement to get the faceplate to open wider. I'm now going to try to work on a couple of methods to stabilize the hinge on the faceplate as well as the wire through it's full movement.
Thoughts?
