Hi - I bought some chrom plated brass ferrules from JannsNetcraft for my PMQ ($1.79) great value.
Should I make small sawcuts and try and form a square where the ferrule buts on to the rod, I think the process is called 'Crowning'. or is it OK to leave the ferrule as is ?.
FWIW, I just *slightly* rounded the square off the last inch of the blank, so that when the ferrule is fit on, there is only a small gap on the flats where the ferrule is round. Each of these I filled witha very thin shaving of boo and *carefully* tapered it to the flat. You will find with the cheap ferrules that the blank end that fits into the male ferrule has to be shaved down a lot more than the female end. Just make sure you don't shave/sand down the blank too much, or it will be weak and snap right there in a deep flex.
