(snip) One of the major problems I see are commercial trailers with very small grade 30 safety chains and cheap Chinese slip hooks . Grade 70 chain has over three times the strength of grade 30 chain (what you find at your hardware store and flea markets). I also used Grade 70 slip hooks which have the same strength as the chain.

.... the trailer comes off rolling 60-65 mph, crosses over the center line into a group of bicyclists, killing several, maiming others.
I can weld, and ive gotten "okayish" at it over the years, but I still dont like welding anything that which it breaking could hurt anyone. a mans gotta know his limitations.
