Unless someone on the board has an old pair lying around, I doubt you can build or buy them for under $25, without using plastic. And why not Sintra (or other plastic)? More durable than cardboard, and lighter than wood. Several members have built outstanding Sintra gauntlets for a fraction of the price of a kit.
actually i purchased a 4'X 8" sheet of 1/8" sintra for 30 bucks.i only used half of that for my entire costume.you can make your gauntlets for very cheap if you have the have the patience and manhours to do so.if you tackle our own scratchbuilt gauntlets be prepared..its a pain in the arse :facepalm
We are currently working on sintra gauntlets but haven't finished them yet. We basically are going to layer it up after making the basic cup shape around the arm. To shape the sintra, we are going to use a heat gun but others have used boiling water.
This thread has some good tips on how to make wood and sintra gauntlets. http://tdh.prop-planet.com/viewtopic.php?topic=5827&forum=4
I can email you my templates but my knee templates need a major overhaul.
Sintra knees are decent but, like the cod piece, a vacuformed set will give you greater accuracy. I got my cod from batninja who is an awesome guy. You might try him to see if he makes knees and gauntlets as well.
I would use the sintra. $25 bucks really does get you a lot of sintra. I remember a member on the board made gauntlets with plastic 5 gallon pails. They looked really good. Sorry....I can't remember exactly who that was that did them.
that was phantom viper I believe, he also made the bucket armor. I made my first set of armor from a bucket and it came out pretty well, even though I cut my finger with the xacto knife and bled all over the armor
