Comus:
When using an iron tip I use a steel brad (nail)that I cut off the head end and round off the pointy end on the drill press with a file. Pick a brad that is a press fit to the 1/16 hole.
First I use a v block and a multi flute counter sink to put in a drill start / counter sink - keep it small - about a 1/3 back from the entry side of the tip. I made the mistake of using a centerpunch once - made a drill start point but flattened out the tip and ruined it. Using a 1/16 drill (which is why the drill start is necessary) I drill the top hole as vertical as I can, then using the drill as the vertical line I re-adjust the drill clamp to center the drill on the bottom inside of the tip, then drill out the second hole. Turn over and counter sink the second hole.
Push in the ramrod and align(I prefer against the grain) and drill half way through, flip and repeat. Set the nail in the hole and tap through. The rounded tip should cut through any misalignment in the center and "find" its way to the second hole. Mark the tip and rod because the nail only goes in one way now. Pull out the nail, pull off the tip and mix up some JB Weld (2 part epoxy - great stuff) and coat the inside of the tip, don't use too much. Put the tip back on using the alingment marks to get the right hole lined up and re-insert the nail. Tap it home and make sure the headless end of the nail is flush to the tip surface and cut the pointy end off as close as you can to the surface. Tap the remained of the nail even (some will be left by the wire cutter)and tap (tap I say! - not hit!) the nail end in the counter sink with a light hammer using your vise as an anvil to anchor the other end of the pin. Flip and tap again.
Roll the ramrod and tip on a flat surface - like a table saw bed to check for concentricitty and pressure the tip into alignment with the rod. Unless you got the rod to fit perfectly when you inlet it it should move a bit. The nice thing (bad thing) about JB Weld is that it takes some time to harden (like 15 hours) so take your time. Once hard the JB will fill in any "not so perfect" inletting on the ram rod to tip - also double insurnace on keeping the tip on. Before the JB sets, if you have a threaded tip, make sure it is clear of epoxy - easy to do now, but after that stuff hardens - say goodbye to your work.
After the JB hardens, file and emery the result to a nice shine and away you go.
