put the castors on more of an angle, that way your body weight will help straighten up the rear wheels

good news for us, bad news for all the smaller hardware shops around

lol, didnt even think of that... most of my switches have been re-soldered about 4-5 times, so you wouldnt need a new one

um i think so. thats the way the switches i've used work, but theres the easy way to find out- solder it up and test it

well the glue i've got is green and on the container it actually says
"PVC-U pipe
GREEN
Cement
for pressure pvc-u pipe and fittings"
ive had a half used bottle of it sitting for about 6 months and it hasnt changed consistency at all.

5. LAST QUESTION... Ok so I got 3 switches from an electricity store, I got 2 push ones 1 for the stun gun and 1 for the lazer, the other one is an on /off switch... the on /off switch has 3 points or little thing to which to solder wire, in the other hand the push ones have 2, what is the 3rd one ...

ok then. i have my firearms licence and didnt even think about it... i could post you some to try 8) . as for the pistol, i'd probably alredy have an actual pistol if it weren't for the crazy laws regarding them :? :evil: EDIT; i still like shooting actual firearms, but you cant really make them you...

thanks, :) , really appreciate it,,just one question,i need some 4.5 mm ball bearings ,for consistant ammo,and im in sydney australia and cant seems to find any, does anybody from australia have a source??? or maybe even online as a last resort.. .177 air gun pellets? should fit perfectly in a 4.5m...

Actually nah, you don't know. There are big differences between a 2-stroke and a pulsejet.

Yep, differences but also a lot of similarities. Both exhaust waste gases and intake fresh air via the same port.

not in any 2-stroke motor ive ever seen... they have both a intake port and exhaust.

im sorry that im not contributing anything, but STOP double and tripple posting, its what the edit button is for

i think he is planning on using alcohol of some sort, as this is the stuff used in the "jam jars" in the first post...

its reasonably difficult t get a pulse jet running on its own, let alone running with a projectile blocking the exhaust half the time. on the other hand, it might be an idea to start thinking about a 'combustion machine gun' using the basic principles of a valved pulse jet, only not really pulsing. ...

didnt mean to make it look like that, i didnt even notice untill you pointed it out.
so not really worth all the stuffing around to make it with only a small performance boost... ok, i gues ill go the easy route

i am planing on making a coaxial valved cannon in the near future, and i was wondering if the shape of the piston could improve performance at all. is the curved piston going to be of any advantage? im assuming it would be but i could be wrong. curved http://img14.imageshack.us/img14/5199/coax1.png ...

dont worry, ive spent more than my fair share of my time involintarily sitting in corners
