@@wamindustries Here's how I did it. I duct taped one end of the pipe. I filled it with sand, then dumped the sand into a foil turkey pan. Heated it in the oven for 450° for 35 minutes. Then using a funnel, dumped it back into the pipe. In less than a minute, the pipe becomes very flexible. I then used a jig to shape it to a kettlebell handle. In my case, I used competition style handle measurements as a guide. Good luck!
