Pic. #1:This were the elastics from the fireing pin will attach to the barrel, put the green pegs over the elastics so the fireing pin will not fly out of the barrel when you fire.

Pic. #2:The stand connects to the barrel like this.

Step 6: The Amunition

Simply look at it and build it.

Step 7: Loading and Fireing

To load this you push the fireing pin back so the red rod goes throught the snowflake and clip an orange connector at the end of the red rod for sort of like a trigger/safety.

To fire simply unclip the orange connector.

Have fun and feel free to modify.

this is not a mortar for one you drop an explosive shell down the barrel and its on hindges for angleing your lauch 2*

If you adjust the ratio of the rods on the support then it strengthens it and reduces rod-bend.
