Thread: How to pin? Several techniques that I have seen... Max, Glen etc...

The trick to start peening for me is to cut the rod to the correct length, making sure I have just the right amount needed, not to much, not to short and flatten both ends, especially to get rid of the rough cut from the cutters. Gently taping and going in circles alternating between both sides of the scales. I do my polishing of pins and washers after I'm done peening. Knowing how much of the length's rod will be enough is something you learn with experience and peening a few hundred times. As with everything, the more you do it, the better you get.

Max, what pattern do you use to triple stack? I.E. Large #0 brass with a small nickel silver sandwiched between a small brass?

After peening rod in vice, I assemble with washers, cut excess rod, and final size on belt sander. When I file, too easy for me to accidentally score the scales.

Polished ballpeen and jewlers block as noted above.

After tight, I always final shape wedge edge to assure clean fit, so end up with MicroMesh on the scales, after tight. So I MicroMesh the pin head at same time.

I realize the pivot will get wacked to tighten someday anyway, but why not make pretty from the start.

Funny, when I use the belt sander to final size it is too easy for me to accidentally score the scales. I'm the opposite and find more control with the hand file. Just another way to skin a cat

Some of you guys are true experts! ME? I find myself unpinning and trying again waaay too often! I have become a true expert in disassembly! I suppose that is how you learn! One thing I have found helpful is to anneal the pins by holding in the middle with needlenosed pliers and, using a propane torch, heat the ends up good and dunk it in the water. It seems to make the peening more effective with the rod I currently have. I find it is better to err on the long side, until you bend the pin! It is nice to see a good pin job! I find myself gravitating to the pins first when looking at a guy's work. This is the art of assembly, and all the work in the world sucks with a poor pin job, IMHO. Still, Tight is tight!

That's a very valuable point. One person's technique, may not be right for someone else. It's a blast to find what works for myself.

Me, I enjoy working scales on the sander, making the outboard face as contoured as reasonable. Others like making sharp beveled edges.

As I reflect maybe since I spend so much time sculpting on the sander, that's where I am comfortable. When I pin the razor, I constantly move and rotate, never holding square to the block as I tap off center to the pin.

Put a file in my hand, right between those processes, I suspect I cant think 2D and hold the file square after making an organic shapped scale, and anticipating pininng in a similar rounded manner.

This may be an example to not fight your personality, but use it to your advantage; Just do what works best for you.

This is mostly good experience and sound advice. But nickel-silver can become brittle if it is overheated in annealing. This used to be a danger with the cupro-nickel jackets (substantially the same stuff, though sometimes with more nickel and a whiter hue) which were once used on rifle bullets. Bullets could break up too easily on a large animal, leaving him with some score-settling time, and bullets were known to weep tiny amounts of friction-melted lead core, making them assymmetrical in weight, and inaccurate.

You should aim for the least amount of annealing which will make the end feel softer when lightly filed.

Hi when I am doing the pins I use a 1/64th brass sheet and have a 1/16th hole drilled in it then I lay this over the rod and file down till I hit the sheet and you end up with a perfect pin every time then I use the same brass sheet with different size holes drilled into it to cover the scales while I buff the pin up. I use the Dremel with a leather buffing wheel and Solvol Autosol to do the final polish.

Here is a photo of the jig I use and the brass sheet the jig has a slot cut into it to put a razor in it so I can work on the spine with out risking my fingers.

The little nut at the top of the jig with the dimple in it is used for making the pins and the holes next to the brass sheet are used for removing pins.

I'm still figuring out how much pin. I like Exile's approach

For peening, I thought I had read it from Glen, but I'm not sure. I use the back (convex) side of a stainless tablespoon as my hammer. I have a small hammer, but the spoon is faster for alot of light whacks.

I always put 2 extra washers on the pin and cut flush. Remove the extra washers, make sure the pin is flat and smooth, then peen. Works every time.
