Front sight removal/measurement question

I have a (sporterized) Krag that's been in the family for years and has a Williams peep sight on it. It's almost near the bottom of its adjustment , so I want to install a slightly higher front sight on it. The front sight (not orig, either) is dovetailed in w/a standard 3/8" dovetail.
1. How is the height measured? My guess is that it's the height minus the dovetail.
2. Which side does it come out of. It's got a dimple on the RH side of it.

As a basic starting point, center the peep sight in its elevation setting and measure the distance from the center of the peep to the center of the bore. The top of the front sight blade should be about the same height as the center of the peep.

Let me rephrase my question. I'd like to measure the height of my existing sight. I know how much higher the new blade needs to be.
However, I need to know which direction it needs to go to remove it. Hope that clears things up.

Marbles sights include the dovetail for the height measurement.

Also,

From Brownells:

Q: How much higher should my front sight be if I were to install a receiver sight?

A: The front sight should be approximately .125" higher if a receiver sight is used. Depending upon the characteristics of the individual rifle, the front sight may require more or less additional height.

I believe that is with the receiver sight bottomed.

I've always wanted to know:

looking from the receiver down the barrel (like when you sight the rifle) at the front sight, is the front sight:

1) placed at the right side of the dovetail slot and drifted into the dovetail by pushing it leftward

2) the reverse

3) makes no difference

in a nutshell, is it drifted to the left or right to get it in the dovetail.

thanks.

When I machine dovetails, I set them up to enter from the right. Unless I see an obvious difference from one side to the other, I treat the others the same way.

Williams make the blades in a limited number of increments. You can eye ball it with a scale or calipers and get close enough to pick which height it is without removing it.

Williams will be stamped on the bottom. After you use a plastic rod to drift the existing site blade out(left to right)! Williams are measured from the Bottom of the Dovetail to the top of the Bead!!
