Kids + history channel = "Dad! Can you make me a musket?"
So this is a non-firing child's toy to be used with much imagination and only 1 moving part (ie the ramrod).
It's not a replica of a flintlock - there is no firing mechanism.
It's the idea of what a musket is for a kid to play with - you just pull the imaginary trigger and make the appropriate Ka-Blammo type noise, then go through the motions of pretending to re-load with the ramrod accessory.
If you know how to make a flintlock mechanism then give up your day job and become a gunsmith or send me an instructable - as long as it's not knex cause I don't have any of that.
But hey, it looks like a musket and the kids love it so there you go.
If you want an instructable for this one then let me know.
