I added about 0.002" of solder to the top of the needle only in the idle range, and only on one side.
The neatest way to do that would be to coat/dip the end of the needle in plumber's solder flux and
then apply the solder immediately thereafter. The solder will "take" to where the flux is as the affinity to bond is high, but it'll not want to bind nearly as readily where there is no flux.
The other nice thing about this "opposite" method is that you know the starting position. Removing the excess is easy if you have flux, a bit of heat and a wooden cocktail stick. The wood can't damage the brass because it is softer than metal.
kind regards

I used a very fine electronics solder, so it was easy to apply to solder only where I wanted it. It didn't lay as flat as I wanted at the transition from solder/no solder because of the surface tension of the liquid metal, so I had to file it smooth after it cooled. Otherwise I had a step change in AFR, and that wasn't good.
