Have fun with it and I am not responsible if someone gets killed or injured!!!
Step 1: Make Your Template
first you need to cut the PVC pipe for a normal sword I think that 3 feet of PVC is good. Use pipe cutters to cut your PVC to desired length.
Step 2: Cut Pool Noodle
now you want to cut your noodle. no matter how long your sword is you will want a handle duh! I like my handle about 8 inches long so I cut my pool noodle to 30 inches.
Once you cut the pool noodle push the PVC up through the hole in the pool noodle until there is only 8 inches of PVC sticking out. then you cover the pool noodle in duct tape and pus eletrical tape on the handle and you are done!
If you have any questions or suggestions then leave a comment and I will get back to you.
