That's a great idea Rob!
The wooden ramrod, w/o the crown protector, can be more aggressive than sandpaper insofar as the crown is concerned, and I've redone a few crowns over the years that were damaged really bad due to the ramrod constantly being used in the same position, which is typically 6 O'clock, due to the location of the thimbles.
When you can actually see, without any magnification, the damage that was done by a ramrod, you have to wonder that with such a crown, how on God's Little Green Acre did that gun every hit ANYTHING?
I like your idea Rob, and as soon as I find that "crooked just right" Hickory Rod, I intend to build one just like it.
I have tried a couple of times to put that just right "bow / bend" on blank Hickory rods, but I have yet to get it just right.
Hank from West Va laughs at my "stronger, and sometimes bigger than usual" rod tension springs to hold my ramrods in place....according to him all I need is a good West Virginia limb, one that resembles a Dog's Hind Leg, and that'll get the job done just fine, and that ol' boy does know a thing or three about muzzleloaders....
