Parts
-
Make sure you have everything you need.
-
Cut pieces are not pictured. You will cut these yourself.
-
PVC pipe joints need to be twisted when gluing them together. It makes a better seal. However, there are a few spots where twisting can't be done.
-
-
-
Lay out pieces to make sure you have everything.
-
Dry-fitting the entire project is a great idea. Some pieces may need to be sawed down to fit correctly. Lining up the handle can be tricky.
-
Draw guide marks. These will help you know when you've pushed the pipe in far enough, and keep it level.
-
Picture 2 shows an example of guide marks.
-
-
-
We will be starting with the bottom and working upwards.
-
Remember: PVC glue dries VERY fast.
-
You will spread PVC glue around the short pieces and inside the shaped pieces.
-
Push and twist together. Make VERY sure that they are all level. If they are not level the rest of the pieces will not fit.
-
Quickly after/while inserting the pieces we laid it flat on the table and pushed it flat. This makes sure the whole base is level.

Before and after paint
-
Put a 12" piece of PVC into the top. This is where the marshmallows will be loaded and fired.
-
You will need to solder wires from the sprinkler valve, switches and extra wire to battery pack. Hide battery in Altoids can.
-
One switch is your safety, the other is the firing switch.
-
Load marshmallow. Pump with bike pump to 30 PSI. Flip your safety off and fire. The marshmallows will go far, so make sure you have a safe area to shoot them.
