Latex Chainsword

My latest production, a latex and foam chainsword, ordered by a fellow larper for a warhammer Larp, taking place around Montpellier, France.

The core of the sword is a fiberglass rod, the foam is plastazote 45, painted with latex and coated with isoflex primer.

A little LED flasher is included in the sword's guard, providing a nice extra FX, that can be used on the battlefield as tactical signal.

Oh man, it's absolutely lovely!

how sturdy are the saw teeth though? do they need added reinforcement or is the latex coating that tough?
Zapan99's avatar
The trick is to carve the teeth in the central layer of foam. Plastazote foam have a very high tensile strength. as long as the shape is not too narrow, the foam can withstand a lot of abuse.

Well now i really have to search harder for the plastazote. It sounds like the miracle foam. It can take full contact at that thickness?
Msevvy's avatar
thank you for all your advice :-)

Plastazote is considered safe with a minimum of 3 cm (1.18") around the fiberglass core on the slashing edge, and only 0,5 cm (0.2") on the flat sides of the weapon.

I have a question. Since im going to make a weapon too, where can i find latex foam in general?
Zapan99's avatar
There is a misunderstanding in your question. Latex weapons are made in polyurethane foam sheets (plastazote, evazote) glued together on a fiberglass core, carved and then coated in about 7 to 10 layers of liquid latex.

I strongly recommend you to purchase your materials in LARP online shops, and to follow tutorials in your own laguage only. STAY AWAY FROM ANYTHING AMERICAN, not only your weapon would end up ugly, but more than that, it would not comply with your local LARP rules.

Only use second grade materials (like gym mat foam, or bamboo core) if the weapon is anly decorative, like for cosplay.

Yes, I made the interruptor face one of the engine gaps.

The background is just a dusty iron door closing the garage in the farm I live in.

TO AWESOME!

How the LED is turned on?
It's in the second "engine" gap from the bottom?

And cool background by the way! :)

Would you ever make another? :D

Honestly, this sword was custom made for a client, and my first and only attempt at anything not medieval.
But I have a long time abandonned project about a flint gun and a crossbow that I want to steampunk.

How much was it? I have mates who are periodically tempted by chain swords but can never afford them.
Zapan99's avatar
If I remember correctly, I sold that one 80 euros. If your mates can't afford that, they can still make their own, it's not that complicated, Maker Power !

its space that's the problem most of the time - living in a flat makes it hard to work with strong glue without feeling ill

You can look for an artist center workshop (at first they look down at you, until they realise your art generates envy and fun) or you can also check if your local larp association organises latex workshops.
