paulvallandigham mentioned pinning the ferrels (tips) onto the ramrod and I figure that some of you folks who have only owned factory guns may not be familiar with pinning the tip on.
Here is a picture of what he's talking about.
This is fairly easy to do so rather than send you to the Gun Builders Forum I'll describe it.
You need a 1/16 dia drill bit, a 1/16 diameter brass rod (available at hobby shops or many hardware stores), a pocket knife a small flat file and a little hammer.
With the tip in place, drill thru the metal and wooden rod for the pin.
Use your pocket knife point to make a chamfer at each end of the hole.
Insert a short piece of the rod so about 1/16 is sticking out of both sides of the metal tip.
Using the hammer, carefully deform the ends of the rod down into the chamfers on both ends. (This may leave a small lump of the rod sticking out of both sides of the tip.)
File the lump(s) flush with the metal tip.
Using this method you are not only PC, but you are no longer relying on a press fit or some glue to hold the tip(s) on your rod.
Don't be tempted to use large pins. You want as much wood in this area as possible and the strength of a 1/16 diameter pin is much more than the wood in this area.
