Sorry I waited so long to reply guys my computer crashed . Flone and maniac I am going to take both those suggestions into consideration. And starman this is going to be a slow build not a buy everything at once. And finally DYI were you being sarcastic with that post?

Willing to go bigger if anyone can put up a good argument. In terms of performance, bigger is *always* better. The bigger your launcher of course, there are downsides - higher material and running costs, harder to move around and to store etc. - so in general, I would advise that you make it as big...

Ok, I've come up with a solution. It will be an inline cannon so that I can get a much more powerful shot all the bends in an overunder take away from what I am trying to achieve. Just one question, does anyone see a problem with a 5in-4in bell reducer? I would think that as long as I use primer and...

Yes, your probably right I should have thought this post out more thuroughly(not spelled right) then I did, as now I realized how many crucial details I left out. I'll make a design and post it tomorrow then you guys can yell at everything I did wrong .

I'm planning on making an ultimate combustion and I want you guys to help me plan everything out. Due to the fact that I'm fairly new at spudding I'm not sure about all the aspects of certain products. This will be a propane(metered and injected) and chamber fan the whole nine yards... The first ste...

Yes, your probably right I should have added a coupling but was very hard to get all four gaps close enough.

Future plans: SPARK STRIP

Well then I would say not too shabby. Your best shot(that you could find) got some good distance. Any plans for an even better cannon in the near future?

Here is my 2nd cannon and I decided not to go too crazy but chamber fan and metered propane soon to come. Oh, and a red laser mounted to a rail at the chamber end of the barrel, currently waiting on laser. There is no paint on the gun it is all black and red electrical tape because I do not have the...

Were these shots taken with measured propane? or were you still using spray and pray?

Well sorry crowley and jrrdw but with 30+ pages I dont want to be on my computer all night.

Very cool, im suprised the performance hasnt sacrificed due to all the holes in the barrel.

You did say that all internals that overlap the stock will be hidden inside, and if im correct thats your chamber there under the barrel.

Nice job man, some good progress for a second cannon. Any plans to go bigger with more sparks and propane?

Great job man looks awesome but where do you fill it? is it a car tire valve?

Putting the heat issue into perspective I guess I could try putting some sort of wadding behind it, even a potato piece.
