Trailer Hitch

 

My friend Billy said his boss had a broken trailer hitch.  We both corrected the hitch but also put on a replacement trailer jack that was left over from another trailer repair I did for another friend of mine (I KNEW that old trailer jack would be useful in the future!).  Here are the BEFORE pictures...

The picture above clearly shows the broken/bent trailer jack, and the one below gives you an idea of the crack in the hitch itself.  My guess is that the trailer was jack-knifed one too many times while backing up...

The repair was pretty simple - cut off the trailer jack with a plasma cutter, then cut off the trailer hitch, grind everything down, install an internal 2-inch OD pipe about 8-inches long and then MIG weld the seam, making sure the weld got full penetration through the hitch pipe and the internal backing pipe.  Add on a couple of loops for the safety chains (which were cut with a bolt cutter and then TIG welded around the loops) and the rest is history.  Most of the plasma cutting, MIG welding, and all of the hard grinding work was done by Billy who I was teaching to MIG weld.  He did a great job, and is fast on his way to becoming a great welder!
