So I've been wondering if you could make your own oil rig with a glass spoon pipe and a Ti nail with a dome. The only time I've seen a handheld rig is with Pyptek's Prometheus concentrate kit. I like the handheld rig idea, and I have a few extra glass spoons that I wouldn't mind drilling out a little bit or something to that effect. If you guys have any ideas of a safe way to make a portable concentrate kit for a glass pipe, let me know!
There is a ton of spoon sized pipes with 14mm male joints on them at my LHS. Goes for like 30 bucks, clear with a wigwag, no nail, clear dome
