Don't forget some crush tube for the bolts so you don't squash your chassis rails.

His mounts will bend over the top of the rail before the rail itself is damaged.

Maybe upsize your mount material to 75x10 or 90x8. This will allow you to get 2 bolts per leg, and reduce the numer of leg/mounts back to 2 per side. This will make it far easier to dodge all your fuel lines, driveline mounts etc.

Oh, and as JC said, more bracing. You should have room for 50x5 welded on edge. Make it atleast 75mm long.

yer im going to that's just where im up to now

[got_bar_work]

Thonk about round pipe over the square aswell
Pipe dont have and corners to dig into rocks logs etc ot will slid over it
The square will try and dig in and u have to drag 50mm surface area over something instead of 5mm

[harry loane]

yer ok guys thanks heaps

[alien]

yeah make the gusset bigger, and lets face it, no one needs a side step - angle those sliders up on a 45 degree angle so they dont smack into everything you're trying to drive over.

[DarkHorse]

I needed steps - especially with the bucket seats in. Angled them up 45ish deg so they sit just less than a shoe-width out from the sills. Function as sliders and steps , and sit almost inside the line of the tyres (tyres are now 30mm wider than this):

[got_bar_work]

I love my steps
It keeps rocks off my doors and people can jump on them when u need a bit of extra weight on one side to stop from rolling

[harry loane]

yer true

Could use the square tube and lay on its corner? so the corner of the tube points down? There is more actual material in square tube to round tube of the same size, so 50. 8 x50 50. 8 = 63.4 round so It could work out stronger, would that be any stronger fatzook?

[dono1]

Definitely put some gussets in there to stop or bending on big impacts.

Yes, rotating the square section so as to limit drag and impact to the corner of the square will help.

From an impact POV, the square tube will resist bending more than the equivelant diameter round tube, but will be heavier.

My personal preference is to use a higher grade round section, rather than square. It looks nicer IMO.

[Trypt]

Isnt a circle stronger thena square aswell?

[KEENSY85]

All square tube starts off round (apart from alli) so 63 round Makes 50 x 50, a peice of slit to make 63 round is 199mm wide by what ever thickness the tube is to be,
while to make 50 round the material is actually 159.5 wide so there is actually less material making it lighter and in my theory weeker then the square material,

But in saying that I thought square was stronger because of the courners, but as a structure round might be I'm not sure, but fatzook would know, fatzook?

[Jackson]

Square section should have less internal stresses than round section due to bending because of its higher second moment of area, for the same diameter and thickness.

However round is consistent no matter which direction the impact is, square will behave differently depending where it is hit from in the same way an I beam is only strongest in one direction.

I can't really comment practically but maybe something to think about, rotating the square around so a corner is pointing down might bite you in the arse because you are potentially reducing the area of the impact so increasing stress.

I don't think rotating it around would help with drag because surface area doesn't determine friction.

[KEENSY85]

I don't really agree but I'm not a boily or engineer, but from experience in fabrication,and construction. when square is normally incorporated into drawings it is usually turned on its side as it like using triangles,

I'm not having a go at u, this a good topic were onto know

[Fatzook]

Well regardless of the science behind it all, these sliders are for a sierra, and 32NB medium pipe will see the OP through most situations with out folding up. Same goes for 50x3 SHS. Its not a comp truck.

[KEENSY85]

True, I got a little bit carried away (blushing)

[nicko]

I made mine out of 50x50 4mm box and 32nb medium wall tube. Like so





See how they are angled, have Madeleine a few sets like this and it works great, nice and strong and just slides right over everything

[harry loane]

how did you mount them??

[nicko]

Like this

[harry loane]

How did you mount them to the car like over the rail or through it?

[nicko]

The u slides up the chassi rail and 2 bolts over the top of the chassi

[harry loane]

Yer ok mad they look sweet and love the front bar need.one of those too

Fatzook... your TSOR link in your sig isn't working.

Can you make them for a SWB Vit?

x2 wanna make some sliders for me XD

[DarkHorse]

Bets are off with TSOR at the moment.

[nicko]

I can probably make a set if fatzook can't. Just as a backup plan

[masterA]

To give you an idea regarding bracing etc....these are mine.....

[Skippy]

i like the ones that fatzook made for the cruiser. step and slider, nice work! its exactly how i would like mine to be.

[alexxx]

any one made some for a GV?? id depart with cash for a good set of sliders

[Chop]

Same here alex, if we could show enough interest for a nice fitting sill protection for the gv maybe one of the fabricators might come up with something! I can dream can't I?
