cracked subframe

[knight_ripper]

went on a campin trip this weekend....loaded up the shee with all the goods...but I think it was the whiskey that overloaded her.

 

anyway....after 106 miles...we got to our destination....I was unloading and noticed the crack, right behind where the grab bar bolts on. I see from my search that this is a common problem.

 

Mine was weak from bending it previously...but broke cuz of the strain. Now its cracked on both sides....bout half way thru.

 

My poor poor girl is in pain and needs fixin.

 

Problem is Im racing in Vorra this year...and I got three short track races coming up here in OCT. Im screwed with a new frame right now....so ....

 

I can weld for a temp fix right? If so...whats the frame made out of?

 

And Im not a welder...so I will be taking it somewhere. Is there anything I need to tell the welder....ie...special instructions?

 

thanks for all the help....the HQ is the greatest.

Its just normal old mild steel. Welder would have figured that out with a magnet tho...

I'd like to elaborate on "normal mild steel", and amend it to SOFT mild steel.

You might want to have that welder also put some gussets in there, box it in, whatever so that it won't break/bend again.

 

When I say soft, I don't mean like butter, but its not going to be the same grade as a 1018 you can get from a steel supplier. At least not what I've found.

Some of that shit looks like it wasn't tubing to begin with. It looks like sheet thats been stamped or formed in some places to resemble tubing. Threw some calipers on it, and it isn't round thats for sure.
