View Full Version : Hardening a frizzen

I have to do something I never had to do. My friend brought over one of those cheap Spanish flinter pistols he picked up from an estate sale. It will not spark because the frizzen is too soft and I am sure it is made from tool steel and not hardened properly.
I usually replace parts and locks but this gun is not worth spending $2 on. So my dilemma is what temperature do I temper at after hardening to get the best spark.
I plan on heating it cherry red and dumping it in water but it will be too hard and brittle.
It's funny that after over 50 years of building and repairing muzzle loaders, this is the first time I am faced with this.

44MAN; I do not remember the correct temp, (crs) I do remember that when I "halfsoled" frizzens with a piece of saw blade I tinned it with soft solder, then hardened it. When the solder joint between the two parts melted it drew the temper to the correct point (heat from the back side). Maybe that will give you a temp to work with, sorry I do not remember the draw color.

44man, you'd be safer to quench in oil than water. Both quench mediums will give the same outside hardness but the inside of the oil quenched won't be quite as brittle. After hardening polish the face of the frizzen. You want to heat to about 300-325. This will give you a light yellow color on the face. You can to do this in a toaster oven. When you reach the desired color just requench in the oil. If this doesn't work the steel is probably of a lesser quality than anticipated, and you may need to use something like "Casenit"...Ray

A lot of the spanish frizzens won't harden worth a s^%t. I use Doc Carlsons hardening compound which I find is much better than Kasenite. I also quench in salt water bath as I find that works best. Back to the spanish frizzens most will surface harden abnd wear through is short order. I think the steel is alloyed with swiss cheese. I prefer to get a frizzen tht is close from TOTW and fit it to the lock if I have to. If the lock is the Maslin style consider replacing the whole lock as the rest of the spanish locks are no better than the frizzens and a cheap lock in a flinter is a sure ticket to either flinches or disgust.

Done this myself.
Heat in lead pot and cool slow. Soft and time to work it into shape.
Cut and bend so to say.
Heat to cherry red and pop it into water. Hard as glass and will break
just as easy if you try to bend or shape.
The act of soldering the sole onto the frizzen will make the sole just the
right hardness.
This is how I have soled a Frizzzen and might be better ways . But its a start.

What do you think of TC frizzens. I think I may have already worn one out after onlya few hundred shots.

What I've done is used Kasenit.....heated to proper temperature (cherry-red in dark room, magnet will not stick), plunged into Kasenit, heated back to cherry-red, quenched in quart of oil (water can cause stress cracks), cleaned up, redo entire process, clean-up again, and then draw temper by heating to light straw color/oil quench in well-lit room, taking care to not go to brown or blue, as by then it's gotten too soft again......

T/C will re harden well for you. MTN gave the right instructions for kasenit, I prefer a little different technique and I use Doc's compound. I have hardened these by wrapping in leather and sealing it in a tin can and then quenching the whole works when it is red hot, but that takes a real eye for the heat. A good harden job on a T/C frizzen should give you 500 plus shots as high as 1000.

KCSO, what do you use for heat?.....I'm limited to a couple of propane torches (one won't put out enough heat even for Kasenit)......your method is as good, and probably better, but lack of good heat source means Kasenit for this boy......

I got it red hot and put in Kasenite, then kept heating it and melted the Kasenite on the surface. When red hot again I dropped it in salt water. I drew the temper at 350 degrees in the oven for an hour and just let it cool down.
Once the proper temper is reached you don't have to quench. Just let the metal cool slowly.
I make springs by hardening and then tempering in 600 degree lead for an hour. I fish out the spring and set it on the top of the pot and unplug it. Never had one break yet.
I am spoiled from buying good locks that never need any work. A good frizzen will last forever, unlike the old ones and some of the cheap junk.

Farenheit or Celsius degrees ?

You might want to check the barrel on that pistol before giving it back. Years ago, Bob Olsen sent in pictures to the Buckskin Report, of a barrel he had sawn in half, that belonged to one of his deputies. It was from one of the cheap Spanish pistols. He had originally took it to Bob with the same problem as you are dealing with, a soft frizzen. Bob, being rather strong minded, cut the barrel with out asking first, just so it could never be fired. His deputy was a bit put out at first when Bob told him what he had done, but got a better attitude after seeing what the inside looked like.
It showed that the barrel had been drilled from both ends, with the drilling just in the same basic neighborhood where they met in the middle. Rifling was done with the same method. Needless to say, not accurate at all, and most likely unsafe to shoot at all.
Bob kept the barrel in his gun shop for years, since it was a good example of a cheap firearm, and what to expect from one. I'll bet his son Lance still has that barrel.
