It seems like working on a Mandalorian helmet is similar to playing tennis...precision over power, place over pace.
Regardless, fantastic work, and thanks for sharing the link (and thanks to Ohl'd Vart for the link to begin with).
Are your helmet colors a basic black and white?
As someone who has only ever tried to play tennis once, I'll take your word for it.

My base color is a very light grey (think mist) with a matte white, black and hopefully gold accents. I haven't quite figured out the gold bit. I want it to swirl through the armor...we'll see what happens. I am also using some bright red in my soft parts.
My WIP for soft parts and armor if anyone is interested stop on by.
http://mandalorianmercs.org/forum/index.php?topic=183386.0http://mandalorianmercs.org/forum/index.php?topic=183388.0Progress today:
I started by tracing my visor onto my helmet. I didn't cut it out yet as I still needed to add the vent in the back and figure out what I am going to do with the ears. And of.
course by this point you just have to try it on.




Next I cut out my ears. I used 3 layers of 3 mm sintra (PVC foam board) for this....probably could have used leftover bucket but that would have been much harder to shape and sand down.


I decided that for now I will try magnetic attachments for my ears. I may change my mind later but if I am going to do it, it must be done before I assemble the pieces. I was thinking magnetic simply because I was doing two 'left' ears (WOF Boba Fett left ear pattern, no RF) and that gives me the option to change them later if I don't like the look. I also still have the option of permanent attachment.
So I made the marks, drilled the holes, sanded them down and glued the magnets into the ears.




As it was drying I heat formed the other two layers of the ears to the correct shape. Once the glue for the magnets dried I glued all three layer together.



In the drying times I also worked on my helmet and various other armor bits.
I marked and cut out the back vent. Then I used the same template but cut it out a little bigger. This bigger chunk is going to be mounted inside the helmet as both support and to give the helmet the 'layered' look. Because of the overlap where the wall and hard hat meet, I ended up having to trim some of my hard hat back to make room for the vent backing. Then I attached it using contact cement first to hold it in place then a thin line of hot glue as insurance.




As you can see cutting straight lines on a curved surface is a skill I am still developing.

Also for future reference, when adding the support band, pre-cut the area that the vent will go in before mounting it into the helmet.
Now for the key slots. I altered the pattern to better suit my design and made triangles!

I heated the bucket pieces to make it a bit more malleable and went at it with an exacto knife. Then hit it with a bit more heat to give it a slight curve...mine is a little too curvy in the pictures. I had to flatten it out some to fit into the space better.




Then I mounted it using the same method as I had for the backing.

(I damaged the bottom rim when I cut the hole...don't worry I'll fix it.)
Now take those two little half moon shapes that come with the key slot template and cut them out. I just dug through my bucket scraps till I found some that were close and just shaved them down.

These little bits are going to go on the top and bottom of the vent inside the hole. Secure them with the contact cement and hot glue same as before.



Now for the visor. This bit was both exciting and scary. I carefully cut the visor out. Next time I am going to cut the visor out on the top layer before I mount it to the helmet. As I cut I ended up tearing apart one side of the cheekbones purely by accident. Guess I was pushing to hard to get the leverage needed to cut into the bucket. Oh well, better now then later. The side that gave was the side I had only used hot glue on. The other side, which was the combo of tacking with superglue then hot glue survived pretty much intact. I will now recommend that method over the other for durability.


I reattached the cheekbone with superglue and then hot glue. As I was doing this I was hit with an idea....used the tip of the glue gun (Very HOT) to smooth out some of the rough seams...glue melts slightly and you can sorta smear it smoothish...made my OCD feel better even if it did nothing else.


And TADA!!!!

I still have a long way to go but this is a very rewarding point. I probably won't get much done tomorrow but I be back soon with an update.
Quick question though....does it look to big? I fear it may be too wide for me. Maybe once I add the rest of my armor I'll look more balanced.
