Cobalt Blue Butterfly Straitjacket Beauty Shots...

I love the way this butterfly straitjacket turned out. 

It's the first time I made a butterfly jacket with an attached hood, which gives it a clean line and close fit along the neck. There's no double layer, where the hood meets the collar. I even think I can go tighter on the neck next time, especially with this soft leather. 

It's also the first time I tried out detachable crotch straps, which have some unique benefits: namely the ability to remove the straps completely if you don't need them, but also to move the buckle part to the front or the back, depending on the position. If you have you slave laying down, the buckles work better on the front side so they won't dig into her rear end! 

The crotch straps also are calling for an added harness of some kind to hold a Hitachi Magic Wand in just the right spot...

The good news about the straps held in place with snaps is that after a couple of test runs none of the snaps came loose or un-snapped. I am thinking this might work as an ongoing solution. The only drawback is there is a fair amount of work to make all the attachment points, buckles and snap sections. Add in the extra leather you need to create all the connections, and the removable strap option will add to the cost, vs. the strap that is simply riveted permanently to the jacket. 

Now if I can just find this leather on sale again... 

Cobalt Butterfly Part 4 - Setting Snaps

I had to learn all about snaps for this project. I hadn't used them much until now, and since the ability to remove the straps was the impetus behind this project, it seemed like the right time to figure out how to set them properly, and get a quality result. 

The first thing to know is that there are 4 unique parts to a snap, each with their own name: the cap, socket, stud and eyelet. The wider "female" cup-shaped socket pairs up with the cap, while the smaller "male" stud is held in place with the eyelet. 

I wasn't having good results initially, so I visited my local Tandy leather, where of course they recommended the "deluxe" setter set with anvil. I was having a couple of problems. One: the post often bent when I was setting them with the mallet. This caused the socket or stud to be offset to the side, and out of alignment. Maybe the post was too long? Maybe snaps come in different post lengths, like the rivets? 

The helpful guy at the store said "No, you want the post to have a bit of length on it. It's not a bad thing. You're probably not setting them correctly." Turns out there is a technique. 

He took the setter, anvil and a pack of snaps. We went to the back room, and he (using a poly mallet) started gently tapping the setter, all the while rotating the angle of the tool in a circular motion. He stopped part way to show me how the post on the cap was gently rolling down, like a turtleneck sweater. He just kept tapping, softly and slowly rotating the setter, taking his time to get the cap post snug against the socket. About 6 to 8 strikes per rotation. 

I think in retrospect I was probably hitting the setter too hard, and only straight down - as I would when setting a grommet. Instead of giving the cap and eyelet post a chance to fold or roll over by gently coaxing it from all angles, it was just bending at the bottom, and once bent a little there was no way for that roll-over to happen at all. Once you understand the technique, it's problem solved. Thank you, Tandy guy! 

Now back to our jacket... First I set the snaps on the long straps, using a spacing guide. 

I decided to use a pair of snaps at each strap end to share the load a bit. It seems like one snap wouldn't be enough. 

 The idea is for these to attach to the loops on the jacket with the cap facing out, like so: 

 Looking good so far...

 When setting the cap side, you want to use the indent on the anvil that matches the size of your snap. 

I'm also experimenting with using a thin piece of leather between the cap and anvil to avoid scratching the cap. 

When setting the stud, you want to use the flat backside of the anvil. 

The same setter is used for all 4 parts. 

 I made a smaller strap to become a buckle keeper - it started out as a one and one-eight-inch strip, glued and folded to about a half-inch wide strap. 

 Using a double-thick section of strap as a guide, these are cut to the proper length for a belt keeper.

 I know there is a dedicated tool for this, but I just use a staple gun and a wedge of wood to hold the keeper together. 

 I can staple directly into the wood, then carefully pry it out with a screwdriver. 

 The ends of the staple get folded in and flattened with a tack hammer.  

 They look like little Japanese Obi.

 For the buckle-end strap, we start with the buckle, strap, keeper and template. 

I mark the position of the buckle tongue hole with the template. 

 Punch it out with the 0.625-inch oblong punch. 

 Slide on the keeper...

 Insert the buckle tongue through the hole (Make sure the buckle is oriented the right way. You can tell by the tongue which should be pointed down at the end.)

 Use a template to mark the position of the rivets. 

 Load a cap into the riveter.

 And rivet the buckle (and keeper) in place. 

Buckle number one, complete...

 ...and number two. 

So after a few more holes, and lots of tap-tap-tapping, we have the snaps complete on the short "buckle-side" straps. 

 And here's how it looks on the jacket:

 Now the fun part: I get to see if it works! 

Hmmm... I guess I still need to punch holes in the long straps too, but for that I need someone to try it on... Honey, are you busy right now?
