I figured this was the easiest way for a chain adjuster/tensioner. It's simply a idler, a flanged bearing, with an offset center that I can set the free play. As I didn't think a spring tensioner would work on account of both forward and reverse tension applies. In the pic you can see by the first one the top chain is curved. And the bottom pic with the tensioner adjusted the top chain is straight from sprocket to sprocket, and that is forward rotation to where more pressure (should) be applied by pushing a load.




And a pic of the part, I'll be using a tooth washer for some more security of keeping it in position.
