Attaching Armor: the Punch/Stud Method

We worked with Kimchi4U Cosplay & Props recently to create a tutorial for how he created this innovative way of attaching his Mordred (Fate/Apocrypha) armor. Take a look!


In partnership with Cosplay Supplies I was able to make a full armor build for Mordred from the anime Fate Apocrypha.

This is a tutorial for a type of mounting system I have not yet seen before in other cosplay builds. Since I was making most of the armor out of worbla, I knew that I would be needing something substantially durable for fixing parts of the armor to my body.

Seeing as I have not yet seen this before in other projects, I am going to call it the Punch/Stud method. This method of mounting systems uses the expansion of your body to keep armor parts on your person by friction.

The Punch/Stud method is comprised of 2 parts of armor having holes punched into once piece, and studs made of worbla on the other. The sandwich method for both pieces would probably be ideal as this mounting depends on having both pieces of armor fairly resistant to forces in order to perform as intended.

The two pieces of armor is encased around a part of the body and the studs are fitted through the punched holes to lock in place. It should be a fairly tight fit, and if this is done your body trying to expand back into place from the compression will secure your armor in place.

I punched the holes in the armor pieces by taking a power drill to it with a bit intended for putting holes in wood. The studs were made with scrap pieces of worbla and fixed to the surface of the armor. Both stud and punch holes were reheated and smoothed over.

Make sure to do lots of test fits before finalizing the location of the studs. Otherwise you may end up with armor that is either too small or too big to securely fit onto your person.

Mordred on the official art does not show having studs on parts of her armor. I took some creative liberties in order to use this method of mounting by accepting that I would not be able to hide the hole and stud and placed them in areas where it would make sense.

This method was used to fix my chest/back pieces and calf/shin pieces to my body. Its a method of mounting that is deceptively simple, but also depends on being custom fitted to your body to remain effective.
– does not take up a lot of space in order to work
– very secure and durable way of mounting armor
– simple in technique. not very complicated to pull off

– substantial changes in body dimensions may result in armor no longer fitting as intended
– visible on the finished product. there is no real way of hiding the fact that this exists on your armor. there is a visible hole and a stud protruding (best to use in areas where it makes sense for the armor to have studs or rivets)
– requires sturdy materials. using this with foam alone will probably result in a fit that is not as secure


Thanks again to Kimchi4U Cosplay & Props for sharing this technique with us!
