what kind of spudgun are you looking for pneumatic or combustion have you looked at the spudgun wiki

http://www.spudfiles.com/spud_wiki/index.php/Main_Page
perhaps after you have read it you can design your own with the parts available to you

What changes between these 3 configurations? which is best?

Now I'm not going to be one of those people that just says "learn english", but it is really very hard understanding what you are saying. If you are using a translator, I would recommend a different one.

Ok! Scusate l'inglese! Comunque vorrei fare uno spudgun medio solo che non so quale forma fare! A me piacerebbe fare il 2(foto che ho postato) pero vorrei qualche dritta sulle misure! Perchè usando misure inventate ho sempre avuto il problema del tappo che saltava! L'ultimo che ho realizzato ho usato 70cm di tubo da 200mm di diametro e la canna lunga 1.50metri e di diametro da 70mm!

Come misure, guarda questi dati (sono con una canna di 2.5", piu o meno come 70mm)

Come puoi vedere, non e necessariamente il tubo piu grande che ti da la massima potenza:

Puoi predere uno da un accendino, guarda qua.

Dipende dal tipo di carburante che vuoi utilizare. Se uzi uno spray, il serbatoio deve avere un volume di piu o meno 1.5 volte il volume della canna. Se usi propano o butano (a concentrazione di 4%) is serbatoio deve essere piu o meno 0.75 volte il volume della canna.

Per ezempio per una canna di 1.5 metri e diametro di 70mm:

spray: serbatoio di 200mm lungo 280mm

propano/butano: serbatoio di 200mm lungo 140mm

I speak English, Spanish, Italian and [censored for privacy purposes], my native tongue, fluently. Other languages I have to get by with simple phrases like "What time does your husband usually come back?" ;)
