Making Crank Pins

On the heels of John LeMerise's need to make crank pins for a Kato Mikado for his PRR I1s project, I tested out my idea of making them by turning down some wire nails.   The short answer is I think it works great.

I did it with stainless steel #17 wire nails (because the store didn't have #19, which are thinner, requiring less turning-down).
Home Depot does have the #19, but they just didn't happen to have them at my store today.

I also made some with regular steel #19 wire nails.  It is easier to make them from these because the steel files down more easily.  I still don't think that the rods are going to wear down a steel pin, even though the rods are harder stainless.  But if you worry, then make them from stainless.

Here are some photos:

At some point I'm going to have a go at etching my own rods.  Now I know how to make the crank pins.

Hmm... I'd rather make
crank calls...

Two scientists create a teleportation ray, and they try it out on a cricket. They put the cricket on one of the two teleportation pads in the room, and they turn the ray on.
The cricket jumps across the room onto the other pad.

great idea.....

Any idea how to make the eccentric crank rod (or return rod depending with side of the pond you're on...) using this idea?

Item number 1 on this illustration:

for most people. that is not a manufacturer of n-scale steam for the masses....

the eccentric crank on the main crank is aa least a two piece job

the main crank and the eccentric. since most people add a rivet at the end of the eccentric arm
there is a third piece.

when I have done this the arm is a drill job and then I solder it to the main crank
after that I glue the eccentric pin to the arm (after I put it into the arm to the valve work)

HO guys use rivets... which you can make.
