Huge shout out to
@brino , great bender of the north. Thanks to Brino, I was able to skip thinking completely this weekend and do some recreational machining and adult beverage consuming. His vise flavored metal bender works wonderfully. Following his expert tutelage I copied his design with parts laying around the shop.

The only items purchased were the 3 shcs that were 12mm metric. The bearings I had on hand were just slightly too small for my 1/2" bolts. The drive nut is a beat up flange nut from a 5/8" t-slot clamp set. The drive roller is 4140 cold drawn and I have no idea what the jaw material is but it is a 3/4" square drop I picked up from the local steel yard. The bearings are cheesy Amazon buys, I always buy 10 packs even if I need just one. I had to turn the knurling off the shcs on the drive side. I originally had some 80mm length screws that the heads were not knurled and bored the drive nut to match them. I had to go to 100mm on the drive side and the 100's were knurled and didn't quite fit. I thought it easier to turn off the knurling than further open that nasty flange nut. I also added bearings under the drive roller thinking it might make turning easier. Overkill I am sure as it took very little torque to rotate material through the setup.

The mission: My game feeder has been ransacked nightly by coons. Here is a pic from last week.

The design of the feeder leaves corn between the two barrels that the deer cant get to so that is low hanging fruit for the coons. Im OK with that but it seems like they are able to reach far enough between the barrels to get to the source. Don't blame them for that either. Since there is an endless supply of coons in the area, keeping them out is only real option. Using Brino's design I was able to quickly make a metal bar that sits half way in the opening between the barrels. It also sticks out about a 1.5" from the barrels. This cuts the opening size in half and pushes the coons further away from the source. Coons will still get a few grains around the edges which I welcome.

Now everyone is happy and I am not a mass murderer.........er.
Thanks BRINO! Your design is well thought out. I think that before I turn more round bar, I might put oversized washers between the bearings to act as guides. Starting with 7' of round rod is about as much as I could control. And now I know my vise needs more room...............
Oh yes, don't knowbody tell your significant others that you can make perfect circles. My wife caught me in the act and now the request are pouring in.
