I just made this chain guard for my mower. The angle iron was an old bed rail I found laying in the dirt near an old shed at the edge of our property. The chain was some old stuff I had laying around, unfortunately it was two different brands of 1/4". On the left half, it took 6 links, on the right, it took 7. Just don't look too close /forums/images/graemlins/tongue.gif.
