How far are you willing to go? (got carried away by that title :-) The Primus 96' lipstick may be tiringly debated here. However, whilst we are waiting for the soon-to-come launch of a reproduction series, I cant let go imagening a functional Frankenstick . That using fittings and adapters from the world of plumbing, cooling systems, welders, auto/machine industry, and topping it off with a 4,5 or 7mm jet. The threads on the lipstick is (or so Im told) M16x1,5 so that is where to start. There may be drilling, taps and dies involved, but the idea is to keep that lathe and bracing away. I do not insist it can be done, but I think that given the seemingly endless selection brassy thingies that are being made in our galaxy (..), it may possible be a matter of enough determination and perseverance in such a persuit?
