Bak Flip, Bak-Box repairs
So I don't think I posted this up either, this has to do with the repairs to stuff after the testing run we did after putting on the Heavy Duty National Springs (thats the title of the previous post), anyway when I forgot to strap down the cooler the box that holds the racing jack got loose and got "Tore up", Bac-Box also had damage from previous outings... the last time was due to failure of the crappy Bak-Flip rail clamps.
While I had everything out I also did some other needed repairs. The bak Flip P.O.S. Rail Clamps were each removed one at a time and red Locktight added. I learned that using large Bar Clamps to hold the clamp square when removing or tightening the clamps to avoid the tendency for them to twist off. I was able to get 100Lbs or so of torque slightly deforming the aluminum clamp body.
The Bac-Box was put on the bench and inspected. I noticed a fatigue tear in the side of the aluminum frame. I added some thin aluminum “L” brackets to double the thickness. And fabricated inside braces from unused equipment stand metal legs. The L brackets were JB Welded and clamped overnight. Surface was protected by tape and glue area sanded prior to application of Glue. The inside clamps riveted on the outsides and used self taping hex screws on the inside into the aluminum framework. I also plan on strapping the box down to the bed to eliminate any up or down movement, and have an unused Mac-Tie Down point directly under it. I don’t think the Bac-Box will be giving me any more trouble.
