Step 1: Materials
- 1 3/4 in pvc pipes cut down to 18 inches (45 cm)
- 1 3/4 in dole rod
- 3 3/4 in Galvanized tube straps
- 7 #10x5/8 in pan head phillips
- 2 #6x1-1/4 in drywall screws
- One Door hinge
- 3 extension springs varying in size due to the distance and power needed
- Degree marking block
- canon support wood
Step 2: Process of Cutting and Assembly
First you must cut down your pvc pipe to ~48 cm and ~53 cm for your dole rod
Step 3: More Assembly
Screw in your pvc pipe into your barrel support beam with Galvanized tube straps
Step 4: Measurements
Use your protractor to locate the necessary angles needed for the proper trajectory and launch of your marble.
Step 5: Marking the Angles
Make lines ~ every 1/12 inch to decrease the angle by 5 degrees.
Step 6: Properly Address Your Angles
Use a slanted block for your angles. Start from 45 degrees and have a screw behind supporting the block
Step 7: Springs
Screw in two screws where ~ the pvc pipe starts and ends and add spring and a protective metal piece. So that the screws does not go flying with the springs.
Step 8: Acquire the Package
These simple steps should allow you to make the best marble canon, if you have any questions please comment below.
Step 9: Finding the Variable
Before you use the kinematic equations to find you initial velocity you must find Xoy ( the height of the end of the canon to the ground) as well as the time which the pink paper provides you with the formula.
Step 10: Calculate the Remaining Variables
Use the following variables and kinematic equations provided by instructor or this instructable to be able to find the initial velocity of your marble.
I hope you guys found this somewhat useful thank you and enjoy your very own marble canon
