2:42 I made the threads in the aluminum tube just using a bolt. There's no need for a thread tap;

I did not use substances to sealing or any type of glue. The parts are simply fitted firmly;

Only the burner and part of feeding tube get warm. The reservoir remains cold all the time;

Preheating is needed;

The cotton wick limits the alcohol flow;

All the parts are basically garbage an empty deodorant spray, tubes of an old aluminum antenna, a cotton rag or wick and bolts.
