The chainsaw I ended up buying off of Ebay instead of creating my own due to time constraints. It started off as an ugly yellow so I decided to re-paint it red.
Distressed the licence plates using my black paint on rub off technique.
Bought the 1in round PVC pipes plus a coupler to use as the handle of the weapon, and spray painted them silver. Unfortunetly I rushed and sprayed on too thick so you can see permanent drip stains on the back side of it. Have patience when it comes to spray painting people!
Also technically Atomic Wonder Woman uses a square sign pole, but I decided to go with the round PVC because a) It would be easier to take apart, making it more transportable and b) It would be con safe (most cons don't allow real metal or wood).
For the leather neck strap, started figuring out what buttons to add, of course one of my branded buttons would have to be on it. ;)
Further distressed the ties on the skirt, splattered and rubbed black paint on them. Attached the chain handle to the belt (it can come off). I also made it the correct size so I can take the chains out to pose with, if needed. The chains are just halloween prop chains, I didn't make them. Would have been more a pain and waste of materials to make it than buy it.
