IT WORKED!

Been working on my .54cal GPR for the last two days. Coned the barrel yesterday, using a Joe Wood tool. Messed up a few pieces of sand paper at first, then everything just started working. You just let the tool do the work.
My T/C cock and a dozen Rich Pierce flints arrived yesterday. I spent the afternoon installing the T/C cock and a new frizzen. Roundball's instructions were perfect, with no suprises.(Thanks roundball)
Being a total newbie, it took a couple of tries to get the flint installed correctly. I got beautiful sparks. Primed the pan about 6 times and the ignition was great. Since I live in town, I had to make do with some lite blank loads. All 6 charges went boom. With about 20 strikes on the first flint, its still in good shape.
We have rain forcast through Monday, so it will be next week before I can put some lead down range.
I checked the old frizzen with a file and it is a bit soft, I will try to heat treat  and may be able to salvage it. Anyone know what RC hardness I should shoot for?
Thanks again for all the help.

Those frizzens are not tool steel.  They are case hardened, I think.  In this case, you have to case harden them again.  It's a good idea to cook the hardened frizzen in an oven at 375 - 400  degrees for about an hour afterwards.  Let it cool out of the oven to room temperature.

I have a tempering oven. If they are case hardened, that could explain the soft spots. I might even try to forge one from some 1084 later on down the road.

Packharden that friz in charcoal. It could be 1018, for all it matters. Then temper it per Taylor's recommendation. A good, deep case will work like a charm.

Quench for hard. Draw the face back to 375 or so as Taylor says, the pan cover and hinge to blue. I try to keep the foot harder than blue heat sinks will keep the blue from getting up the frizzen face. I use a little welding torch to heat the pan cover.
Some alloys like 4140 will never really spark well no matter what.
