Heh, haven't seen SF mentioned in quite a while, definitely recognize your username from there though. You should still try a pulse jet project if you have the space for it! The last time I built one it only required an angle grinder and small mig welder(+a spot welder improvised from a broken microwave, purely optional though). Or... I do remember a neat how-to from Colin furze(youtube) for making a turbojet using only a hand drill and grinder. It wasn't exactly pretty but it definitely ran.
