OT - High Tensile v's Stainless Steel

Thanks Ingtar, yep you read it correctly, it passes through the chassis rail to the captive welded nut on the inside of the opposite wall.

At the moment I have a 3/8" bolt (316 stainless) that passes right through the chassis rail and clamps both sides of the bar mount to the chassis rail. Looks nice and neat however it's only a 3/8" bolt as it has to pass through the captive nut.

I don't think shear force would be the major issue unless the bar was forced upwards as the bar mount is a full U-shaped section that fits over the chassis rail. It's also hard up against the end of the chassis rail at the leading edge which you would think would stop it pushed back in the event of an impact.

So in short, I think it's 'clamping' strength that I need.

You're right, the bolts should provide clamping strength only, then the friction between the two plates should hold the bar on.

If it is just a bar, and hard up against then it should stop it pushing back (without bending the rest of your car :) however if you ever try to pull anything with it, shear strength will be more important. Whether this is a winch, recovery points, pulling trees out of a garden or landing the bar on a rock or something... you never know which might get used a few years down the track with all thought of bolt type forgotten.

Given that the bolt is passing through the rail, I take it there is no hole on the opposite side of the bar. If it was mine I would be tempted to drill a hole so that a short bolt clamps the two tight, rather than pulling the opposite side of the rails.

That's just my thought, I guess it depends how you use your vehicle and what you can see yourself doing with it. Also, if you are having trouble finding the right size HT bolt, there are a few companies around that specialise in fixings. Whole warehouses full of nothing but nuts and bolts, leave places like Coventrys for dead. If you speak to some tradesmen mates they should be able to direct you to one in your area.

LOL thanks Mike, have often thought the same of yours when I've seen your posts.

Great dogs aren't they.

Cheers

I am admiring the tray top modification shown on your rig profile.
Was it done here in SA? - and by whom?

Would you do it the same again, if given the opportunity?
Why aluminium? If weight were not critical, would you go steel with a timber floor??

Any comments for me to be aware of, as I have a GU patrol & I am considering modifying

thanks & Cheers

Rick,

To tell the truth it's not mine. I came across this one in Penola last year. I also posted on here asking some questions, so try a search.
I was led to believe a company in Queensland did this type of conversion.


Mick.

Hi Richard

What do you do for a crust?

Regards

Richard

Im a slave for the goverment paying them money.

We have a few business interests, refrigeration, fabrication, electrical and engineering plus a couple thing out side those industries.

Why, your now going to give me a hard time are you?

I know I should keep my mouth shut.

Regards Richard

No I'm not

I was just wondering, as you are very knowledgeable on a lot of your answers.

I was just asking to be sure the knowledge was coming from someone who knows.

No harm meant.

Some time knowing so much can overpower some people on this forum .. I have learned just to get over it...LOL

Cheers

Richard

You're too modest Richard.......... you forgot to mention that you also manufacture whistles for kettles!!!!

God now you're got me confused

Yeah Roachie Iv'e got to come and see you soon about venture financing of our new place in China, 16000 square meters of factory and about 390 employees.

Spoke to Lucky and he said that with the money you spend on the truck each year you would be the ideal investor and he said....d.rkt.ft.t.f..y..yy..hh....f.ff.....uu..vgf..d.. as well.

Richard we have a few new projects we are working on at the moment being a self homing kettle whistle and a anti theft device too.

I am slowly learning not to respond to the posts I have in the past and yes overpowering people can be a issue.

I answer posts because I like helping people out not because I want to be better then them or show them up, Im more then happy to recieve criticism as long as it,s backed up by a suported view.

We are all here to learn and Iv'e learnt so much off of this forum it's astonishing.

There are some very smart people here.

One thing I don't like is people causing trouble.

Oh well this forun is not the place to discuse that so I will leave it
at that.

So Roachie about the money I come and see you Friday!

Regards Richard
