Cannons to left of him,
Cannons in front of him

Storm'd at with shot and shell,
Boldly He rode and well,
Into the jaws of Death,
Into the mouth of Hell
Rode the Tombstone."...

I'm not a huge fan of combustions... Probably because people hardly ever build them as cool as you have built these beauties. Very original and innovative, and also very pleasing to the eye. They defintely deserve better ammo than potatoes. Compound rounds maybe?

Forgive me if you already answered this in the other thread but you're not using metered propane are you? They look like spray n' prays.

Looking very good. However, a list of changes between this one and "Revision 0.0" would be nice. :wink: It looks like just the muzzle flash was changed.

Hehehe, ok, on the MarkII i added the same extension/fan housing to the chamber, as on the MarkI, and changed the fan to an 80mm, i also redid the base of the handle after it had developped a pressure leak due to a different design than the steel handle on the MarkI, now the Mk2 is as solid and effective as it's big brother! :)

Thx for the appreciation bro! :) And yeah, im thinking of using better ammo for them, and they use butane, but they're far from "spray and pray" lol! i get a fire/fail ratio of around 90-95%!! Not bad i think for unmetered-fueled cannons. :)

I'm glad you're not using aerosol! That's very good consistency!
