Looking at making some bolt on d-shackle brackets for the Rangie....
What would be the minimum thickness steel I should use...

I would use 8mm cause thats what I got lying around. Wouldnt use 5m or 6mm but would use 12mm if I had it.

I gather the picture is from off the poison spyder customs site...
This is what i just read there:
Poison Spyder Customs wrote:Poison Spyder Customs D-Shackle mounts are a versatile and easy way to create an attachment point on your trail machine. Machined from 1" mild steel with beveled edges to ensure a penetrating weld. A unique feature of this attachment point is the radius machined into its base. the radius allows you to perfectly locate mount on 1.5" to 3" tubing, or any flat surface. Excellent for square frames or tube chassis. D-Shackle mounts are weld-on only and are 1" thick, 2.5" in height, and 3.5" at the base.

yeah it is but they are a weld on tab....they would need to be thicker to allow a good penatrating (sp) weld on either side....

thanks sam
I have a big sheet of 10mm so I reckon that is what I will be using...just needed confirmation that it would be strong enough.

10mm
For stuf like that, i recon what ever thickness you think will do then double it to make sure.
You dont want to worry about it every time you use it.

I think on ARB bull bars the recovery points (at least I think they are recovery points) would be lucky to be much more than 4mm thick.
The thickness of where the shackle goes through a snach block would also be only 2 lots of 3mm thick plate.
10mm will be heaps.

I agree... I've seen stock brackets much thinner than that that were okay - not great, but okay. 10mm will be much better than just okay.
How you position the bolt holes in relation to the hole for the d-shackle will make a difference as well; you don't want the shackle to be able to "leverage" the bracket.
Well, I can't explain it but you probably get what I mean.

Im sure the ARB brackets arn't designed for heavy use as they do bend side ways, more of a towing point id think.
Also they arn't a small piece welded on, its part of the main bar that bolts to the chassis.
The bit sticking out the front is only about one tenth of the overall sheet.
10mm would probebly be ok but the stronger the beter.
So why did they go 20+mm in the pic above then ?

The tabs on the bottom of ARB bars are NOT designed for heavy recovery. They bend like a mofo!!!

I thought those tabs are jack points for a high lift jack???

Ditto - definately not a snatching point - perhaps you could use them for a tie down though.

I have seen several of these tear open when used incorrectly as a "snatch point" ..

The diameter of the pin in the Dshackle gives you a big hint as to the MINIMUMAL size plate thickness required.
