If you have a filter pipe to reference from it shouldn’t be too hard. If you have never own or seen the inside of a filter pipe up close then it might need some study beforehand.
if it will fit then I’d say go for it.
to all those people who are saying “just buy a filter pipe wtf u doin?”
Sometimes you just want to experiment(and/or fuck shit up) and it’s not necessarily the end result that’s the singular goal. It’s about the experience of doing it.
now, is drilling your own pipe for the first time the most sure-fire way to have a filtered pipe? No, probably not, but it’s a necessary step in learning to modify pipes. plus if you get it right, then you get the added bonus of having a filtered pipe RIGHT NOW instead of waiting for the mail or going to the store.
so fuck shit up! And measure twice cut(drill) once
