The reason behind this guide is several questions I was asked by a potential customer. I struggled to provide an accurate comprehensible, answer/guide in under 2,000 characters. Because of this struggle, I went looking for an online guide - and couldn't find one.
So, this is my initial attempt at a guide for setting press studs.
If you find it incomprehensible, please let me know and I'll do my best to make clarification(s).
Setting press studs / snaps.
Stuff you'll need:
What you want to put the snaps into.
Something to make holes for the snap' posts to go through.
The correct sized snap setter.
A solid base to set onto.
The two holes need to be just big enough for the snap posts to be lightly pushed through, but not so tight that you deform the surrounding material to do so.
Snaps are a four part unit - the male 'cup' goes onto the backing piece that looks like a mini funnel and the female 'bowl' goes onto the domed backing piece that looks like a mushroom.
To assemble the male side of the snap:
The funnel piece is placed on the anvil and the material is then sandwiched between it and the cup piece. Hold the assembled pieces in place. Place the small domed end of the setter tool into the end of the post tube and hold it perpendicularly to the work surface. When all parts are in place (repeatedly) tap the top of the setter tool until the post has been 'rolled' to its base and is now holding the cup securely in place. Repeat the process for the female part of the snap.
Stuff you might need to know:
Snaps are designed to be used with specific thickness's of material. Line 20 snaps are designed to be used with 5 to 7oz leathers (approximately 1.9 to 2.8mm thick). If the snap' post is too long for the material, it tends to skew sideways, looks bad and can fail to attach completely/properly.
The male part of the snap 'The cup' is attached to the main body of the material you are working with and the female part, 'The bowl', to the flap/extension piece. When pressed together, only the female, domed,, backing part should be fully visible.
The snaps that you use need to be set with the correct setting tool - the correct setting tool is designed to peen/roll/collapse the post correctly.
When setting snaps, you need to work onto a very solid base - I usually have a mini anvil listed. When setting snaps, I always make sure that I work on a sturdy and solid wooden table, which I then protect by working on an old veg cutting board which sits on a craft cutting board. Working onto an unprotected (or even, an under protected) surface is liable to cause damage; possibly/probably severe and irreparable.
