Couple weeks back I was messing with making some small scale blade for my "better half"
birthday present,(what can I do, I'm cheap ba****d, no diamonds for my wife ;P) ,which turn rather good,well....for the first try.She wanted something like this Bear claw.I made it as a necklace pendant ,but after some thinking I realize that it's not very practical to have it on your neck ,unable to use the blade unless you unstrap the necklace and it wasn't so safe without guard.So we opted to make small sheath which could be placed on her key chain.So i looked for some Ideas on the web and find this "Atwood Knife and tool". Mr.Atwood using "Kydex" molded sheaths and have some great videos on how to make them.
For those who doesn't have a clue what Kydex is, here is some info about it. It's a thermoplastic sheet which means after you heat it , sheet became pliable so you can change it's shape ,after cooling down it's going to remain in new shape,it has very good reputation for rigidity,impact damage,chemical resistance and fire retardancy .After some searching I located local dealer here in Japan, price was right so i order some sheets(At this point I'm still waiting for the sheets) meanwhile I needed right tool to do the job properly,in other words cheap and effective.First i need some source of heat Some people say that heat gun is better option than oven,I personally don't have a clue because i haven't use one and i don't have money to buy heat gun which was pretty pricey around 70 bucks,beside i already had oven I usually use with my "super sculpey" clay figures.So much for the heat source.Next thing is Press,I saw some videos where old blanket or bath towel plus body weight were used,but i had enough tools, some parts and time to make proper one for about 10$.Here is the list of parts and tools I used to make this small press.
3pcs 10cm x 10cm x 5mm steel plate (I already had these , reason for small press $1.00 each)
2pcs 10cm x 10cm x 1 cm rubber foam sheet ( approx.$0.50 each)
1pc 5 cm steel door hinge ( $1.00,note, hinge was more square shaped one,see photos)
1pc M6 x 7cm U shape bolt and nuts ($1.00)
2pc M6 x 7
cm bolt and nut and nut grip ($1.50)
3 small steel plates for the locks ($2.00 for meter)
home arc welder 110v very cheap and very good
dremel tool plus burrs
ruler and measure tape
Black spray paint
