Simple and easy ways.. make one like this..
100% home made, no cost at all
Things you will need
1. 6" (inch) iron or steel pipe
2. 10" X 20" timber piece of any kind (Thickness 1")
3. 16 6" nails
4. 1 bicycle tyre hub with the nuts and bolts
5.10" long uniform wood block for centre (Thickness 1", width 2" prefered)
6. 1" X 1" wood block of 7" length
7. 2 springs
8. Hand drill
9. Fire crackers
Optional: marble balls, Paint & Brush
*** You need the help of a welder and a carpender if you don't have equipments
Step 1: Cannon Gun Piece
*** you can weld two bolts in both sides of the pipe for mounting and dismounting with the body and for our safety.
Warning: *do not use wooden or thin sheets of metal if you want to use this cannon for fun fireworks.
*do not use illegal gun powders or blast materials.
*do not test in public places.
I have used several types of iron/steel pipes to make gun piece, all worked fine.
Step 2: Cannon Body
Next you have to arrange all the timber parts like a 'T' shown in the below pictures, i have designed two types of body.
Whatever the design the gun piece should stay fixed.
Step 3: Axle
Step 4: Making Tyres
*** insert the nails from inside out in the timber ring or cut the rest piece of nail from the head with the perfect match with the hub in the center.
Step 5: Gun Height Adjustment
for that you'l need a screw bolt and a small peace of carved wood blog.
you can screw down and screw up according to desired angle of projection.
In my design, the gun piece can upstand always due to weight distribution from the fixing point. so that i have used a small chain set up to pull down the gun piece when adjusting gun height angle.
Step 6: Finishing
Load the firecracker and insert anything as cannon ball... now fire at will..
**Caution high decibel blast may affect hearings..
Stay away after lighting the cracker
Watch the videos to see the success fire..
Enjoy weekend with fun fires..
