Anyhow. In the video I talk about what I made and how but a few things I left off and they are not in order:

How to set in rivets/eyelets:

Use a punch kit that I have in description. It consists of a metal base and a metal punch. All you have to do is to put an eyelet through your sheet of Kydex, then set it on a base and punch on the other and hit a few time until rivet will expend and look good.

How to sand down the edges:

Use low grit sand paper at first and make your way up to a 500 (fine) and make sure you sand down all the sharp corners EVERYWHERE.

Step 3:

How to make belt loops:

This one I forgot to film, so read carefully. First decide what size of a belt you want to use it with. For mine I had a 1.75 inch width. So that means I need my loop to be in rectangular form 1.75'' long and 3/4'' wide and 0.5'' thick.  So to make them I cut out a peace of wood size of 1.75'' wide and 0.5'' thick (length doesn't matter) so then I took my heat gun and heated up a strip of kydex of the right size with some room to spare and after you get kydex to about 300 F it becomes really soft and you just wrap around your piece of wood and in a few minutes it comes out the shape you want. (if this a sucky description, I'm sorry, English is not my first language)

Step 4:

How to bend the edges of a holster:

Very easy. When you holster about to be done and all is left is to curve it to the right angle, use a heat gun and warm up the edge you want to bend (not Hot but warm) and gently force it to bend where you want it to bend.

If I missed anything or if you need more explanation, let me know and I will make sure to help answer your questions.


p.s. It's my first instructable. More to come.

Thanks this is very helpful. I'm going to be trying to make several things, holsters, sheaths and others from kydex. And your English is superb and the description was excellent. :) Thanks again.

I love Kydex! I started out with ABS plastic but it is so much harder to work with.

SlavicFMJ (author)CementTruck2013-10-24

Yeah Kydex is nice. The 0.06 give the best definition, while 0.093 and up you really have to watch your temperature to not burn it.

This one was the one I made for my SR40C with .093. I just used lower temp but left it in the oven just a little bit longer. I've got a designn idea I've been kicking around for an all-in-one (IWB/OWB/Belt Loop/Removable Belt Clip) hybrid system. Ill post as soon as I have perfected and built the first prototype. The one in the pic is a modified Old Faithful holster.

oh that's cool. I need to make myself a good hybrid holster too.

yep, that is my video. I tried to make this a video instructable, but after an hour it still didn't work, so I gave up and made a picture one. But a link was in the description. Thanks for watching!
