damn sissy bar

well i saw a little crack i though was just in paint put on way home tonight i heard a funny pop sound. looked back and seen it broke. damn cheap chain !!

Sorry to hear that, may not be a cheap chain so much as when they welded it they changed the temper of the original design and made it more brittle. Seen a few other chains that were welded break pretty easily.

damn thing is a SMOOTH clean brake not a jagged or streatch brake

:roll: :roll: :roll: im just glad i dint go chrome it yet i was getting ready to pull it off and send it to be chromed i would be real mad then. i guess now im going to cut some thing out on my cnc and run them up each side out of like 1/4 plate so it will be thin from the front but be like 2" wide on the side with some design cut out and but some bends in it and weld them at the top

Looking at a sissy bar application from a metallurgy viewpoint, this break would have been predicted. A sissy bar is a cantilever design and weak by nature. In particular, a chain sissy bar has a lot of mass and vibrates at a fairly high frequency around the fixed/bolted position. You can expect this break to occur again. You might consider adding a triangle configuration at the base to strengthen the area where the sissy bar is bolted. Just my 2 cents!

Try using hardened chain, it's real expensive but it may help. Letting it air cool softens it while dowsing it in water makes it harder and brittle. I’m sure you already know that judging by the stuff you make!!
