vikans are a doddle

you just need some jets and the right size drill bit,best thing about vikans is the "give" in the plastic so you can use a drill bit that is a fraction small and then gently tap the jets in,its nice stuff to drill as well ,bentleys and other diy brushes are more of a pain (harder,brittle plastic and usually less depth of material to mount jets in)and sometimes the savings are minimal,but jetting a vikan yourself is very easy
