Dragster frames........picture thread.

Very nice!!!

 

any progress on this one!?

 

Re. post #15
If I'm not mistaken, that's Roger Wolford doing the welding.
Back then there were gas, arc, and heliarc. Chassis Research frames were mild steel so they were easly gas welded, chromeoly had to be heliarced as gas and elect. arc put too much heat in the metal (chromeoly) and made it brittle.

 

Actually the original use for 4130 cm tubing was in aircraft frames and they were all gas welded before heliarc/TIG came on the scene. Arc or MIG welding will make a 4130 frame brittle in the area of the weld but only because the heat input is so abrupt and goes away quickly. The same amount of heat is needed to fuse the material no matter how it is input. With gas welding the heat affected zone is usually larger because it takes longer to melt the metal at the weld as even a hot gas flame is cooler than any form of arc type weld (if enough amperage is used).

I stand corrected, and enlightened.

 

My Chassis Research K-88 frame was brazed.

 

wow, never saw that before? got ant pics?

 

Here's pix of that when it came out of my neighbor's back yard. Too Kool!!

 

Here are a few pictures while I was building my Woody chassis. I had the whole chassis assembled on the jig with plastic zip ties and the it was tacked together. I hack sawed all the tubing and fish mouth all the tubing on a belt sander.

 

Lippy did you backhalf your SPE car ??? never saw one built like a Woody ?

 

Heres where I`am at now, changed the chassis a bit for a better seat angle and mocked up the pipes,

 

hey 296moon what motor is that? That is looking good.

 

Its a 4.2 jaguar that I "saved" from a 74 bedford fire engine. should be fun if not quick.

 

Me likey!!!!!!!!!!

 

Meanwhile on the other side of the world another Jag powered rail rises from the garage floor. 3.6 meet your grand daddy 4.2.

The latest pix. of mine .

 

Here's a little progress on mine.... Picked up my Clutch Can and Main Hoops Yesterday. I had to do a little Mock-Up to keep my mind flowing last night!






Time to round up more parts!!!

Cheers,

Yes, it's been back-halved twice. And originally it was 165 wb with inj sbc on fuel but had an unfortunate wheelstanding incident and now is 225 wb. My next car will be a 180 wb SPE with an inj on pop BB chev, high gear, clutch and reverser. Shorty body and no frills. Towed on an open trailer behind my 55 chevy of course. Lippy

 

I Dare you Lippy!!!!

 

A man after my own heart.

 

here is some new ones. first is the mark williams car that we redid a few years ago.





and here is the newest one we did. it is a haulin chassis from massachusetts. Its and ex fuel car they built in the 70's.

bringing her home

and getting her updated to race.

and welding in the helmet bars:


I have more and will try to add some new stuff to this wonderful thread.

Nice

 

The painter got this one to the point where he did not need the frame to line up the graphics any more so it is headed to the blasters and then to be powder coated.

I think I recognize that frame, could it be (pictures I do not have)?<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

 

Update on 220'' fed built by Haulin Chassis in mass.

 

Killer keith....

Just in

"Glenn,
The frame is at the blaster and he is trying to get it done by Wednesday so that I can take it to the powder coater before I fly out to California.

Last R&B Automotive Engineering (Dennis Rollain) front engine dragster built...

I'm a fan of the high shoulder hoop personally...

 

Question: Has that frame been SFI tagged yet?

 

Bruce,
I am with you on that one. I presume that there is a bolt in upright to fill that big hole but it sure does not look as if it fits any SFI criteria that I have.
