cage design

IMHO- HREW or DOM will make no difference if the cage isn't designed correctly. I would think that an HREW cage would do fine for your average rig on here. If I was building a rig that might go end over end (up tall ledges/climbs) or anything more than a flop, then I would go with the DOM just for a little more insurance.
As for the chromoly, it does have a higher tensile strength than steel. But it is not as "tough", meaning that it will break rather than bend in a rollover. The main advantage is that you can got to a thinner wall, while keeping the same strength as mild steel, to save weight. I would never go this route.
 
One word....Triangulation.....
Another word.....Penetration.
If you are gonna do your own cage, make sure your welds are strong. Just thought I'd throw it in there. Sure, tube material is important, but when the welds pop due to low heat/lake of penetration in the material, DOM or HREW is not gonna matter at that point.
 
Can I leave my seats bolted to the floor out should I/ do I need to bolt them to the roll cage? Can I use my stock seats? If not what seats should I use? I almost rolled my blazer this morning so I would like to get started on a roll cage!
 
More desireable to be bolted to the cage so you are part of the cage. If your seatmounts or bolts break then you are simply bouncing around inside the cage, also if your seat breaks loose and your seatbelts dont that could be bad and cause injury.

My harnesses and seats are attached to the cage and the cage is attached to the frame, which is attached to the sliders which are attached to the bumpers.

Bottom line some cage is better than none, but I would definately tie the belts and seats to the cage and the cage to the frame rather than just the floorboard.

Seats: You can use your stock ones but like everything else if you got the money there are better options out there.

Mike,

As mentioned, the best solution (and most expensive) it to tie the seats and seatbelts to the cage.

You can get away with the seats bolted to the stock floor locations, but remember to also keep the stock seatbelt mounts too. You don't want to have the seat integrated to the tub and the seatbelts integrated to the cage, or vice-versa. Given that there is a chance that the cage could move independently of the body, you run the risk of the seatbelts getting a lot TIGHTER and crushing you, or getting a lot LOOSER and flinging you out in a rollover.

A seat cradle can be added later pretty easily, so I wouldn't let that stop you from at least getting the basic cagework completed.

Grab some 1.75x120 wall HREW tube,,get a bender and a mig and go for it.

Your going to make some mistakes at first,,but that's just part of the learning curve.
Study some of the cages you see on CK5,,,PM the owner and ask them for some closeup pictures of how they did something you like about their rig.

I did mine with no prior experience and I think it turned out safe and OK looking...well,,,I LIKE IT,,,and that's what counts....I didn't pay someone to do it for me...:D

and then take it out and wheel it !!!
