rob my soulmate!
this one i just shoot specifically for you and your eyes only!
once upon a time i bought the zeph** flux in a bottle, not satisfy with the nozzle (too big) i modded put a syringe needle (refer to pic) and used it for sometime. big bottle good i dont have to refill everytime (infact i never was), syringe needle good enough for my purpose, but then sometime it got spilled up more than what i need.
later i bought the brush dispenser type. the manual said the flux should be placed in the tube (brush body) but it didnt work too well, leakage etc since its china elcheapo, so i made a twist.. i just refill the brush cap with flux from the modded zeph*** bottle. close in the brush and store right up. from there on i keep painting the board with the brush and never looked back, the body tube is empty and only for "balancing during painting" purpose. i still keep the zeph*** bottle just for the flux storage purpose, and its still close to full amount after months (years?) of usage (2 ounces of flux).
the cons though... i need to keep refilling the cap since its small size and if i dont use it for long time the flux in there will dry up and get darken. i have to add some solvent and stir to keep it flow nicely, but its not much compared to the precision amount of flux i want to put on the board.
just would like to share with you (of course everybody else can sneak in
) and oh since i'm from timezone 12, my workmanship and machinist wannabe can be a little bit sloppy
sorry for that, you can do better.
