hey i beleive shorty header can be done but a pain like waht badass said. the way i think it should be done is... thread enough from the top peice where you can do it reserver... can you picture it?> instead of wrapping while un-rolling it, you gunna need to cut enought to do 1 pipe at a time, and then insert and wrap.. when you get down to the 4-1 part, leave it loose enough where it can be covered with another round about at the base.
if you can picture this? then i htink it will work, i never done this but i was thinking of it for a long time!
