Can I drill a 2" hole in a 5" C Frame?

inertia is just another word for nothing left to move

Just fishplate the holes, it'll be fine...

 

I don't think any mechanic put those holes in the wing ribs....

 

????

 

I get it, rebuild your truck with 6 frame rails instead of just 2, then you can drill lots of 2" holes.....you just have to spread out the load!

 

Aren't they flanged?

 

what's the worst that could happen?

 

Or belled, depending on terminology. Somehow, it doesn't surprise me that "Voodoo" doesnt get it.

 

You'd be wrong, its from a homebuilt website.

 

I got lightening holes in my boxers... But they arent belled. Am I risking catastrophic structural failure?

 

knock outs

 

Why the hell would you bother messing with your chassis just to mount a fuel tank filler tube?????

Just because we can, doesn't mean we should???

 

And we have a winner!

Now looky there. Doesn't seem so difficult, now does it? Not sure why so many are opposed to such reinforcements. But whatever.

 

Hey, let's start another shit storm!!!!!!!!!!!!!!
Looks to me like a gas tank filler pipe, not an exhaust pipe. (note the tank right behind the frame member)

Edit; also note the rubber hose connected to it.

 

But that frame kept breaking while being transported on a trailer!

 

Them's from welding, George!
Where's Plowboy, when ya need him?
In Roth-builds, he'd know the score.

 

I don't know what to tell you about the strength of the frame with a hole in it, but as an EE I can tell you that it will effect the impedance of the frame!

Good thread. If it were me I would reinforce it and never think of it again. I agree with those who say it doesn't need it

I think I have the answer!!!! and it doesnt involve selling the truck...and will end this most stressful of threads!

install an electric motor!..thereby removing the need for a petrol filler tube. SIMPLE!

 

Yes it is. My comment about a shit storm was about the previous posters comment about hoses next to an exhaust pipe. It isn't exhaust pipe, it is a gas tank filler pipe.

 

Come on George, those are triangles....waaaaay stronger

 

So which is it - Reinforce it or doesn't need it?

 

I think he's saying the taillights might be dimmer

 

Subtract the hole. 8^)

yes, I am still planning to drill the hole.
I have very much enjoyed this thread and thank all for their contributions past and future.

 

Should I be starting a tech thread on welding nekkid? Maybe a poll?
