Hey prop makers!
In this simple tutorial, I will be sharing one of my techniques in making a pattern for a dome shaped cap or a helmet base for my cosplays. I hope you'll find it helpful because, I do. Haha! I've been using this technique for almost all of my rounded type helmets and also, some other parts that requires a dome shaped pattern ie; some shoulder bells, knee caps, etc.
Without further ado, let's start building!
Start covering up the half of the ball. Yes, only the half and NOT the entire ball.
You should have something like this. AND YOU'RE DONE!
Go and put a line on the middle of the "bowl" that you've made using masking tape and cut along the lines. Don't go too deep (that's what she said lol) because you might cut the ball and pop it. If you'd look closely, I've already cut mine hah!
You can actually not cut the middle and split the two pieces together but,
I just did this because I find it easier to transfer it on paper (which you could see on the next step)
Peel off the tape from the ball and you'll end up having a curved ellipse / eye shape. After you did the prior instruction,
try to flatten out the masking tape pattern by putting cut lines like what I did on the photos below.
As you flatten out the template, get any piece of paper and stick it there. And because the template is made out of masking tapes, it would easily stick to the paper. MAGICAL isn't it? haha!
VOILA! You're done with your pattern!
All you have to do now is trace out the pattern on your EVA Foam or whatever material you're using for
your build and cut it out using your sharp, trusty knives! Be careful though.
Note: Make sure that you have a sharp edged knife that could cut along your material easily to have that crisp, neat cut!
Make an exact copy using the pattern that you've made a while ago. Remember??
The pattern that you've made? The thing with the masking tape and all sorts of awesome thingy?? Good.
After you're done making the two pieces, you can now proceed on preppin' up your
preferred glue and start gluing each of the edges until you come up with something like these.
All you need to do now is glue the two pieces together and VOILA!
You have now unlocked the skill of making your own dome shaped base helmet!
Here's my T-60 Power Armor Helmet that I recently did using the same pattern for the head.
Now, what are you waiting for?
Go forth and build something!
Good luck! :D
