Knee wall baluster installation

I am redoing the staircase in my house and I am having a little trouble figuring out the best way to connect the balusters to the knee wall. I'll have to cut the balusters at 45 degrees on both sides so that the are perpendicular to the floor and that the rail is paralel to the knee wall. Since I am cutting the bottom of the baluster I'll lose the wooden pin at the bottom. How would I go about connecting the baluster to the knee wall? Should I add a new pin? Should I just use a nail gun? Should I use floor adhesive?

Welcome to the forums! Where will your "knee" wall be located? It is difficult to visualize a knee wall on a staircase. Is that a metal balustrade? Difficult to tell from the pictures.

OK, so there is no actual knee wall, only a skirt. Your newel post will be at the top as you have described. The top part of the skirt you see in your pictures will need to be removed and replaced with an oak (your wood choice) grooved baluster receiver piece. Cut your balusters at the angle of your skirt bottom and insert them plumb in the receiver. You will place a piece of oak lattice between the balusters to dress the bottoms up.
Of course you have to do the same to the top handrail as you go along. A lot of measuring and ensuring plumbness (is that a word?).

If you use what I believe is called a plowed base it holds the baluster in place on two sides.
One finish nail on the lower side and the thin filler strips hold it in place.
I tried to find pictures of these parts but came up empty.
I know there on the shelf at Lowes and HD but there not on there web site.

Can't find anything in regards to "plowed base", its tricky because it is in an angle at the bottom so I can't screw the balusters into that bottom wall since I won't be able to twist them into place...

A 'plowed base' basically has a dado groove along the entire length, after you insert and tack the balusters in place, you cut and install small strips of wood to fill in the dado.

Oh I see, yeah that might work. I also found this article where he just uses a nail gun, not sure if that's a solid install though...

I didn't read the article but looking at the pic, those types of installations normally have a dowel or special screw holding the bottom into the tread. The top is inserted into a hole drilled in the railing and often a brad nail is used to hold it in place while the glue dries. That type of installation is very stout!

You'll have to pull the angled molding from the top of the skirt to make it flat all the way down.

That won't be 45[SUP]o[/SUP]. That's way steeper than the standard for a staircase. You'll need to determine the actual angle with something like a FatMax Xtreme® Magnetic Torpedo Level. One of the vials in that level rotates to tell you the angle of the surface it's sitting on.
