Thanks all,

There's just one about putting the 3rd pin...
I have a disassembled handle that consists on 2 equal parts and a spacer.
Here's my plan of action:
I drill the hole for the 3rd pin;
I glue somehow the spacer to one of the halves of the scale, then I pin them altogether;
I pin the pivot hole;
I pin the 3rd pin.

What is the usual order you gents follow?
I don't know exactly how will I pin the 3rd pin because, unlike the other 2, this pin doesn't hold anything tightly together, I mean, it only embraces one side of the scales to another leaving a gap between those 2 pieces. Should I get some kind of small spacer or a tube to put it between? I'm asking you this because imagine if I slightly squeeze (they're plastic) in the middle of the scales, the 3rd pin will pop out of its original place due to the its size being larger than the squeezed scales...
