"Aquacadets are encouraged to attend these events and the band's concerts in costume. These costumes often include official rashguards, helmets, belts, and masks that are available as part of the band's merchandise catalogue, but also often consist of homemade items. Some members have even formed splinter factions such as the "Astrobats," "Piratebats," and "Ninjabats" and outfitted themselves with homemade t-shirts and other apparel to show their support for the band."
Also, I ask that you read the entire Instructable before you get too exited and just print out the templates and go.
Enough blabbering, let's get going!
Step 1: Materials Needed
-Sewing Machine (If you don't own one you can do it by hand, but it takes a long time)
-Printer and paper (For the templates)
Step 2: Download and Print the Templates
IMPORTANT NOTE: The smallest template(back) was about a half inch too short when I sewed my helmet.
MAKE IT AN INCH LONGER WHEN YOU CUT OUT THE TEMPLATES!
Step 3: Cut Out the Templates
IMPORTANT NOTE: MAKE THE SMALLEST TEMPLATE AN INCH LONGER WHEN YOU CUT IT OUT!
Tape the two long ones together.
And label the side one.
Step 4: Trace the Templates
Step 5: Cut Out Neoprene
Step 6: Prepare to Sew
Set it to a Zig-Zag stitch, and make sure it is at the widest possible setting. Also make sure that the stitches are set to be very close together.
Go find some scraps of neoprene and do a test.
Note: When you sew these together the fabric does not overlap or anything. I'm just placing them next to each other and letting the machine sew the two together with the wide stitch.
NON SEWING MACHINE:
If you don't have access to a sewing machine I suggest you follow this and use that stitch method.
Step 7: Sewing
Step 8: Complete
Step 9: Add-ons/Final Notes
If you read everything and added on that extra inch to the template, you will now probably want to trim off the extra flap hanging out the back of the helmet.
If the helmet is too big/small for your head you can add a chin strap that attaches to the sideburns which will help make it fit better/keep it on your head.
The first helmet I made was rather ill conceived, but the strap keeps it on my head even though it is way to large.
I do plan to make at least one more Instructable on the mask + its template.
Hope to see some more quality homemade costumes at the next concert. Thanks for reading.
