chain tension help

now the chain is pushed up or tensioned up as you can see more slop than most people like but I haven't once had my chain come off

sooner or later the pinch bolt threads are going to so south on you and here is my solution to this.

this shows it greased and ready to go back on and in the orientation of how it goes on the bracket.

here it is all back on and you can see at the top limit. Note the sheet metal screw and socket head bolt these are to stop the bracket from rotating into the spokes . The socket head bolt hole is tapped in the frame and drilled a hair over size on the bracket. I also have shims under the bracket as the frame dia. wasn't large enough and the bracket wallered around on the frame.

here the tensioner mount is a little different and while building the bike I built up the area where the tensioner mounts by welding on donated frame material form a donor bike. You might be able to use a propane torch and solder and do the same thing if you don't have a welder. The solder to use would be the stuff plumbers use to solder together metal ducting.

Here is examples of chain breakers Walmarts on top and my homemade.

another way of breaking the chain with a punch (better to use a nontapered punch )and hammer. I use my vice as a back up opened only far enough so the pins will come out. you can also use a block of wood with small holes drilled to receive the pins as they are knocked out there's many ways to do this etc.
