Saw some historical examples of this device and wanted to try to recreate one. The poker is square stock, the meat holders were square punch so as not to rotate until the user wants the meat to rotate, and the main body that holds the poker is also squared. Meaning you can cook on four sides without the meat spinning on the spit. I plan to test this beast on my next outing in mid February, I will keep you updated. These are also available to order will run $80 plus shipping.
