pencil VS fan

[jason1965]

Here one i did earlier, although a 10mm drill bit it okay you do have to really wiggle it around, so if you find it to tight do a 10mm first then go bigger bit bye bit, i often use a counter sink, and the and the jets fit straight in, and use a little glue around the top of the brush were the neck is on the fan jet, but you do not need to do this, just use the drill bits, and i do a very little trim of the bristles were the jets fit.

I changed to fans last year and to be honest unless you turn the pressure up they're the same as pencils.

both work equally well in my opinion, I've got fans in my main brush and pencils in my short gnd floor brush, I swap from one to the other without noticing any difference.
