IF you are going to glue a Brass or steel tip on.........
Slightly countersink the hole in a brass RR tip. I don't like a 90 degree cut there, I want a beveled cut as it is stronger at this exact area.
Turn the end of the RR down by lathe, turning in a drill, or file with rasp, careful whittling, etc. to fit into the RR tip.
Take some emery paper & roll up about a 1.5" square of it & put it in the tip & turn it & sand the inside of the tip. This cleans out the tip of any oils & opens the pores of the metal.
Cut a small round fitting piece of cardboard like on a cardboard milk carton or cereal box, take a punch & push that lil dot of cardboard down into the RR tip, IF it has a hole all the way thru. Some do, some don't. If hole doesn't go all the way thru, skip this step.
Put some epoxy or dyed brown Accraglass on the RR tip & smear it around good on the area to be glued, put just a little around the RR tip hole, push the RR into the tip & insure you press it all the way down forcing the excess glue out. Wipe off the excess glue & stand it up in the corner Tip Down.
12 hrs later, take a center punch & punch the brass tip about 1/4" from where the wood rod joins the bass.
Take a .067 or .068" drill bit & drill straight thru the tip.
Take a countersink bit or a 3/16" bit & slightly bevel the hole on each side of the tip.
Take a #3 finish nail & tap it in til the head is started into the beveled hole.
Cut off the excess of the nail on the other side.
File off the nail end you cut til you have about 1/16" sticking out.
Take a very small ball peen hammer or a gravers hammer & holding the nail head down on the back of the vise, peen the protruding nail & fill the beveled hole. Don't beat it to death, just lightly peen it.
Turn it over & file 1/2 of the head off the nail, then peen it down filling the beveled hole.
Open the vice to about 1/4" gap in jaws.
Lay the RR & tip there & take a metal file & file the peened nail & brass flush, filing long ways parallel with the RR, turn it over & do same & you can now sand it with some 200 grit autobody paper & ready to stain the rod.
This tip Will Not.... pull off. You may break or twist the RR in two doing something, but the tip is not coming off......
