    I am rethinking building a pair of body mounted rock sliders for the ecj5. Much in the mode of Posi and Focker, I am thinking of something like 4"x2" (4" up on the side and 2" underwrap) angle iron and then having some sort of additional piece to provide some outward protection. Posi did a set of tube steps and both he and Focker used something like a piece of 3/4x3/4 angle iron to create a sort of triangular extension outward.

    Just A Little Project
    Focker's '71 CJ5 Drivable Build

    I don't think I want the steps - but I do want something like the angle iron for lateral protection. Thinking maybe a piece of C-channel that is 2" high and 1" thick. 2" high would come up halfway along the 4" high sides and the 1" thickness would provide a modicum of protection without sticking out too far (aesthetic preference). I think I would be fine with 2 inches of lateral stick-out as well, but more than that I find looks a bit odd without fender flares and my narrow track with only 10.5 wide tires.

    Sound reasonable?...So my question...normally these are made with at least 3/16" angle iron and I would probably use 1/8" c-channel, or should I go with 3/16 channel as well. Also wondering if the c-channel piece on the side would that add enough additional strength that I could go with 1/8" for the base angle iron? The underlap edge would be a bit iffy at 1/8" but I might figure out some spacers to go between the underwrap and bottom of the floorpan and bolt through the floor as well as the side.

    If I ever made a set of these again, I'd cut a quarter notch lengthwise out of round tubing and weld it to thin angle.

    I have definitely considered this...not sure I can precision cut the 1/4 notch out of the round with the simple tools/skills that I have. Will have to be done with a 4.5" angle grinder with cut-off disk or a die grinder with cut-off disk. I might try a prototype. Whadaya think - 1/8" angle iron with 2" diameter round tube?

    That's what I'd use.

    Drop a piece of angle iron on the tubing to scribe your straight lines.

    Those dimensions sound sufficient to me.

    One word of caution... as you cut the tubing, it will want to curve like a banana from heat and stress relief. I'd tack it to something heavy before you begin the cut, and don't release those tacks until it's tacked in place on the angle.

    I used C channel to cut these from which gives me the added strength of the thick 90 degree bend on the bottom. These are thicker than 1/8" tho.

    I like the idea of some lateral protection but I just don't want to add more weight to these.

    I cut some 4x4 box tube on the diagonal, mainly because I like the look of the rounded corners better than angle iron. Been thinking of adding some round tube to the bottom like described above, realizing that negates the rounded edge but we'll see if I actually get around to it.

    This kind of gets to my next question: When I first attempted making these a couple years, I think I had a lot of issue with warping. It was a different design that I was trying and it had quite a bit of underlap and wanted to tie it into a body mount - so I had quite a bit of pieces welded together and it ended up with a large outward bow in the slider that I decided not to use. I did used scrap from a local drop yard and maybe stuff wasn't as straight as I thought, but either way, I am worried about making sure the new ones don't have a warping problem when I add on 2nd layer - be it the round or c-chanel.

    Mine are built out of Aluminum angle and tube. They are steps as much as they are sliders.
    Just a few more ideas for you. This is an early pic before all the bolts were added.

    Yeah, that stuff gets a mind of its own if you're not prepared. Once the two pieces are tacked together, the lamination helps holds their shape. You should still take steps to prevent warpage while welding (clamp to something strong, weld in small steps and allow to cool between welds), because it would be really hard to bend it back into shape after they're welded.

    yup - I tried on the last ones which were 3/16 2x6 angle. They are now scrap for brackets and and other stuff.

    I used some 2x2 angle iron and I believe 6 inch x 3/16th for mine... Then some button head screws and nyloc's with big fender washers backing them up. Then I capped the front edge so it wraps around the fender edge. I can use a hi lift jack on the side too

    I like the built in step. Are those tied into the body mounts or frame? How thick are they?

    What about rusting under the sliders? Did anyone seal up the top edge well? Anyone leave a space between slider and body for air to get in and dry out? This is on my list of Projects as well.

    I just bolted mine on, but in the central valley of California rust isn't really an issue.

    Mine are bolted to the body, they are not tied into the frame. They are 3/16th thick.
    Here is a shot of them before they were powder coated.
    I even bent up a piece of 3/16th plate for the underside. They are a copy of the Metalcloak ones at more than half the price before powder coating them.
