I built mine it is not for sale but it is a whiz bang

it works very well and I built it in my dining room , so you need no fancy shop or expensive tools to build it a drill , and a saw you can cut a 2x4 strait with the book and harder to find parts are all sold buy the inventor
no we use it in the yard store it in the shed but but the dining room had the best light and work space available at the time
mine has a shower head with a valve mounted to it , turn on the water , turn on the power and as soon as it is up to speed drop in 2 scalded chickens about 30 seconds and shut down the power and the water remove plucked chickens
