    Looks almost identical to the Gobi rack. Maybe they stole your idea lol.

    Naw, it is similar but not the same.
    It cost around $450 to make mine.
    There is no way I would pay $1,600+ for a rack! That is the same cost as a good suspension lift. :SHOCKED:
    BTW
    The rack is holding up just fine after 3 years. It has handled everything I have put up there with ease. My only issue is getting the paint to stick to the Galvi pipes. Which I hope to address soon.

    Well knowing you Scar0, if it doesn't exist you'll invent the way to make it stick! haha :-D

    I hear a degreasing, then an etching primer should do well for a purely galvinized surface, but if it was chromated galvinizing it will prove difficult to deal with.

    It is a royal pain for sure. So far, I have tried ammonium wash, degreaser, & etching primer, and now the last resort, this summer will be to sand blast it clean. But I have to be careful with the heat from blasting, I don't want it to warp anything.
    At least it is not rusting where the paint has come off, because of the Galvi. lol

    That is a serious piece of engineering. Great work!

    When I did antenna work I had to paint galvanised pipe for a local police department. Prior to painting the galvanized pipe we coated the pipe with plain old white vinegar. 12 years outside in the weather the galvanished pipe that was painted black still looks like the day I installed it.

    Thank you.
    I'll have to give it a try. Thanks for the tip. :smileup:

    Really like this roof rack, any chance you'd be willing to share the specs on how to build it?

    Thank you very much.
    I would if I could. lol Honestly I do not remember all the specs. The hardest part was all the bent angles. These were a lot of by-guess, and by-golly...
    I went with a basket design to add strength and stability.
    The rack because it is two tiered, is the "basket". I chose not to weld expanded steel on the bottom cross bars, because anything I plan to put up there would not slip between them, and I was able to reduce the total weight that way.

    [​IMG]

    If you look at this Pic, you will see there is a bend in the "loops" forward of the center mounting points down toward the windshield, following the contour of the roof line. Then back up to make the opening for the lights and to also make the front, center, and back upper cross bars parallel.
    If I didn't follow the roof line contour a little it would have stuck way up in the front.
    [​IMG]

    The hardest part for me was dealing with all the angles, there is nothing straight on the top of the Nitro. Front to back there is a bend & a bow, side to side the same, and the front (about 46-3/4"), is wider than the back (about 45"). Front to rear is about 80-1/4"(bottom loop) Top loop is about 75-3/4" front to back. The space between my two "loops" is 1-1/2" on the sides, 3-3/4" front.

    I used 2x4 pieces to set a standard height from the roof too the bottom of the lower rack "loop". Then calculated the bend angles. I also used the rail bolts to locate the front to back and side to side measurements.
    Something else to consider is when welding the small spacer pipes to connect the two "loops" is, the pipe will expand and contract with the heat of the welding process and could change the angles or even cause a drooping/swayback effect. Now, mind you, I didn't have argon hooked up to my welder at the time I made this, so the tubing heated up much more than it would have if I had it. In order to get the drooping/swayback out of the "loops" I had to apply heat to the opposite side of the tubing below each spacer weld. This can be very tricky. A "welding frame" would have made this much easier, but hind site is always much clearer.

    Hey Scar0 do you know if anyone sells the actual rail adapters for a roof basket? Without having to use the crossbars???

    I am not aware of the rail adapters being sold separately from the cross bars.
    I imagine you could use just the rail adapters, but you will still need something going across to support a basket. Most baskets are universal fit (rectangle/square) and not made custom to fit the strange angles of the Nitro roof(see post 31).

    Scar, any chance you have the shots from your original post on this thread? Looking to build a rack before summers hits in SoCal.
