    Rehardening my frizzen

    FlinterNick said: "There’s more than one way to harden a frizzen, I generally just hit with a propane torch and dip it in Track’s Surface Hardening Compound, their instructions says to quench in water, I’ve tried both water and oil, the water works better with a propane torch, oil works better...

    Rehardening my frizzen

    Check and see how a file cuts the face. If truly as hard as it should be, a file should just barely scratch it, if not at all. If the file easily cuts it, it needs to be re-hardened. If it is original as you believe, it may have been forged of soft or wrought iron, and pack hardened ( deeply...

    Sliding patch box latch

    For the short amount of needed travel in wood PB lid springs, heat treating is an absolute waste of energy and time. There is plenty enough natural spring inherent in all steels to work as a short range latch spring. The amount of resistance to flex is dependent on thickness rather than heat treat.

    TOTW Tomahawks

    4140 steel is a chrome molybdenum steel widely used in modern cartridge rifle barrels. Although there are better steels for axes, it does well enough when heat treated for light to medium work. It is not so good for knife blades, as it just will not hold an edge as long most folks would like...

    wooden patchbox spring

    I don't know about originals, but I have seen a few modern builds done that way. No one can tell from the outside.

    wooden patchbox spring

    I have always made my latch springs in two pieces, silver brazed with silvaloy 355. May not be the original method, but I get it the way I want it to be and work.

    Hardening and Tempering 4140 Steel from Rifle Shoppe

    There is not enough carbon in motor oil to even notice as far case hardening. As Dave said. ATF or canola. With 4140, any cooking oil should work. 4140 does not require a super fast cooling quench, but heat whatever oil you use to around 120/130 F. The warmed oil will produce a lesser vapor...

    wooden patchbox spring

    I would cut the excess shaft to the right length and angle, then brass or silver braze a separate thumb piece on. That is how I make all mine anyway.

    How does that lead lap a bore?

    Priming Powder

    Perceived speed of ignition may seem the same, however it has been scientifically proven that ffffg burns faster than fffg. Many believe that fffg is slower to draw moisture than ffffg, and that could be advantageous when hunting in fowl weather.

    Brass tacks

    Unless there has been a very recent change, those brass tacks from Crazy Crow have solid brass heads, but steel shanks. Just to know, for the super PC folks, the original brass tacks had a slightly lower dome than what you will find today offered by Crazy Crow and others. Just a few years ago...

    Testing a lock

    Beware. It is not uncommon for some locks to allow the frizzen to bounce back, and it happens to fast to see it. Put a smear of lip stick under the tail, snap the lock, and look for lip stick on the spring. The cure, if that is what is happening, is to remove some metal under the tail to allow...

    Center-seam knife sheath

    A center seam pattern is first made as a side seam, and sewn as a side seam, although lacking a welt. Then is well wetted and twisted to a center seam. That is the easy way, but there are other methods, some using a butt joint with a special stitch and a curved needle. Articifer could better...
