Cheap Power Jelk Device?
Someone posted earlier that the Power Jelk was just a canning tool. They were right! I found this link with it for $10 and it looks identical. You’d probably need to spend $10 in parts at Home Depot to make a best size roller for you. (PVC pipe, foam insulation pipe, metal screw anchor for center bearing. At least that is what the parts on the Power Jelk look like to me. So you can save yourself about $20 if you are on a real tight budget and have more time than cash.
