I posted a tech thread back in 2008 Tech Month~~Home made metal shaping tools . In this thread I will show the tools that I showed in action. I am not a great metal shaper but I am persistent. Let me try to explain this project because it is a little out of my element. I shaped an old school chopper tank. I don't own a bike so this was just a practice exercise. I have been practicing the basics of metal shaping for the past two years, I just do projects like this and I learn a little bit with every practice project. Let's get started. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ So I don't have any patterns but I have a picture in my head of what I want it to look like. Shaping panels from nothing is one of the things I need to get better at, so this was a good challenge. I started it off with the top so I cut out a blank and put some reference lines on it, so I had a guide for what I needed to shrink. Now with a stump I started to shrink the edge. I found what works best for me is to drive your hammer blow into the side of the dish. (Stump shrinking requires a heavy hammer) This hammer blow will cause a tuck, then all you have to do is hammer that tuck out. If you do any kind of sheet metal Fab, I believe a stump is a must have tool. Alternate sides so you shrink the sides evenly. After I was done shrinking I went to the beater bag a stretched the center. Not too much to explain here, just stretch it until you have your desired shape. Now that it is roughed in, it is still really rough so my next move is to the post dolly. Most of my post Dolly's are just odd pieces of metal. For cleaning up the sides I found that a 2'' ball was just about a perfect fit. I marked my highs and lows and worked it accordingly. (low spots on dolly, high spots off dolly) Here is a picture of the top after some hammer dolly work and a little wheeling.
