the smallest combustion on this site

Unread postAuthor: bigbob12345 » Sun Mar 23, 2008 2:16 pm

Well yes this is the smallest combustion on this site, my searches have come up with nothing. It may possibley be the smallest combustion on the internet but i doubt that. It could also possibley be the smallest in the world but I doubt that even more.

this gun was an extreme annoyance to get to work even with my syringe metering. I have only gotten one shot out of it all the rest have not igniteted. This one shot was probably at a bad mix too and only went about 10ft at about 50fps at most but it got me excited that I finally got it to work. then i tried again and it didnt fire :( and it hasnt since.

But here are the specs

chamber:1in of 6mm pipe
barrel:3in of I dont know wht the ID is pipe
ignition:peizo that is removable(why it isnt in the pics)

pics

The gun(the scrader is a removable endcap sorta thing)

I took the photos in the bathroom because there is a lot of light in there and my cam doesnt have flash

And guess what I got another shot off it but this one was even worse

Hmmm... I remember seeing a smaller gun a long time ago that used a washed out ink tube from a BIC pen for the barrel... http://www.spudfiles.com/forums/i-made- ... 12834.html

you said that you are having problems finding the right fuel mix. are you using too much or not enough for the un-ignitable occurrences. also, plan on making the sites smallest hybrid? lol. i think that would be a cool project.

I saw that, this one is smaller
he said his chamber was 8mm this is 6mm although it does look a little bigger beacuse it is really thick.


sthorne:thats a good idea
Ill have to beat you to it :D
