Big Scott I appreciate your concern, and am truly saying this with the utmost respect, but I want to ask if you know what the tensile strength of A-36 steel is? its around 30k PSI.
Do you know what the tensile strength of a weld is? It varies, but typically you can assume around 70K PSI, mainly due to different strengths of electrodes, but there are many other factors to consider , mostly, the quality of guy welding it,which I don't want to elaborate on right now.
Do you know what the tensile strength of JUST 1 grade 8 bolt is? 150k PSI.
I will have this cage done this week. this will not "punch through the floor"... from any of the interior 2'' "down tubes" there is a 3.5''x3.5'' x.1875'',interior plate with 4, .5 '' holes, directly beneath that is the sheetmetal of the cab, beneath that is a 4.5''x4.5''x.1875'' plate (this reduces the chance of shear, and is the proper way of putting 2 bolted plates together, IMO), and this obviously has 4, .5'' holes in it as well. From there, is another 2'' tube with a bend in it that extends to the frame which finally ends in a .1875'' plate with 4, .5'' holes in it that will fasten through the frame. this will happen in 6 places on the frame. BTW, I am designing this cage as if it was a full weld-in, only making the parts bolt, that allow it to get shoved into te truck!
I will reiterate
"Just because you have this cage, or any cage (WELDED OR NOT!!!!!!!), in a somewhat stock Raptor, doesn't mean you have a TROPHY TRUCK! You have to
drive within your limits and the vehicles, and if your doing that, but you have an "oh shit" moment, this cage will protect you. If the day you get your 2013 and install this cage, then head straight to the desert for the first time ever and do 120,
bad things are bound to happen."
Finally, everyone should get there engines welded onto the frame, there are literally only 2 bolts holding that damn thing in there, what the hell Ford!!! same with the whole suspension, and the cab only has 4 bolts holding it onto the frame!!! RPG, quit bolting on bump stops, start welding them! same with those Fox 3.0's weld those ******* in... come on what are you guys thinking!
I am quite certain, most people (including people in the know) will agree this cage is exremely well built, and is a good option for someone looking for a little added security, as well the abilty to run 4 or 5 point harnesses.
