Rock sliders WELD or Bolt on ?

[makeitfit]

He there learned ones ;)
I'm soon to be making some rock sliders for my offroading shortie. I also plan to make an exo cage for the old girl and work up from the rock sliders.
My first thoughts were to weld the sliders onto the chassis . Then I've read here that's a no no ?
Can anyone explain why?

G,day, makefit. As far as I know, It is illegal to weld to a chassis here in Vic, because it is deemed to reduce the strength and may cause cracking. It may not be the same in every country, or state.

Ah, a nanny state reason lol. Cool in that case I'm welding :)
There's plenty of other stuff welded to the chassis. I think I can get a stronger job by welding it on and then welding the exo cage to the slider. Makes sense in my little mind.

I had plates 12mm plate laser cut say 150 x 150 with a hole in each corner that I tapped to 1/2 in UNC,
These I welded to the chassis [3] each side and then bolted my steps/slider to them using matching plates
with 1/2 in clearance holes, you may only need 2 being a shorty

Good thinking , cheers I like that idea ;)

I have cheesy sliders and they are exactly the same as this. Weld on plates tapped and so the sliders can be removed without cutting.

Also weld flat 2mm or 3mm plate to the underside for the length to stop random branches from being snagged and doing more damage to your sills than you would have without them!!!

Yep I'd read that , cheers will do ;)

I would bolt them, you could weld them but doing so can create a stress point. Also as has been mentioned much easier removing them

Mine are bolted on. Much easier to remove them to repair them - if needed.

Also If you bolt them, its easy to remove if they need a bit of touching up with paint (like mine do)
