C notch

[E$rnie Pintor III]

Has anyone ever c notched the front end of a frame for the front straight axel? My buddy was showing me some pictures of his27 studabaker he has at the shop. They put a c notch and built the purch up hi so the frame can lay low. Has anyone ever seen this done before?

Your buddy did......just kidding...

Seriously....don't see why it wouldn't work...as long as you'd beef up the area around the notch....not sure how much it would screw up steering angles.....bump steer and such...Anyone else??

If you mean this kind of c-notch, no problem.

Just box the frame well.


If you mean this, then no, it'll look like crud.

Like Sarge suggested, the angles will need to be reset. Mostly caster.

First guy understands; I'm talking up front. Notched for straight axel. Not just a little notch but they actoley cut all the way through the frame. Perch goes above frame rails and you have about 16 inches of frame horns up front

I have never seen this done. But then I don't claim to have seen everything yet.
Most people that want a car that rides that low do a double Z'd frame.
Body sit low but where the suspension parts are mounted to the frame, the frame sits at a more conventional height.
As was stated before it most likely can be done. As was also stated, to me if this was a fenderless car and I saw the c-notch showing on the front of the frame........[S
Just my 2 cents.

Could you send us pictures. I would imagine when doing this you could run into problems with steering linkage, tie rods,etc. be very careful and if any thing over design. steering safety, brakes and frame strength are of utmost importance

Yep it would probably work but for both esthetic and design reasons I would do a Z, not a notch.

I have seen it done.. a large front C notch... They put the fenders back on.. so it was all hidden... If built right it should be fine.. but i do agree with the others.. this would need to be hidden for the vehicle to look good

Sorry, I don't know how to post pitchers from my phone. I'll post some on the face book part of rat rods rule...then maybe someone could put them on here for me . Thanks

Here's your pic. I think this could have been done a lot cleaner than this, but it doesn't look too awful. There's no reason it won't work.

I don't like how the heim joint is mounted. It should be vertical not horizontal.

Agree with snopro.
If that joint at the end of the fabb'd split wishbone is the only pivot point I don't see it as having much room to travel when underload. But then I'm not an engineer.
Interesting set up.

I am, and my concern is the same as yours Also, the heim joint will be a more effective pivot and load carrier in the other direction.

I have been secretly wondering about C-notching the front like that and I came up with the conclusion that the only thing bad would be the unappetizing look to it.
The horizontal heim joint caught my eye too. You know, that on a four foot lever[the hairpin], if it moves up and down one foot, the edges of the heim joint[ that are one inch away from the centre of the pivot bolt] will move about one quarter of an inch. It will work, but it looks funny.
Thank you for posting this picture.
Keep on tinkering.

Thanks for posting my picture for me. Thanks for all the input.

What I'm seeing is tiny little bolts in the bracket at the end of the bones. I hope that isn't the only thing holding that bracket on - I'd think a good pot hole would shear those like butter.

Is the spring perch mounted on the front side of that C-notch? If it is, that notch needs to be welded on (not bolted) and boxed - can't really tell if it is. There can be big sideways stresses put on a front axle.

Just my uneducated opinion.

I can't see the tie rod but my concern would be that under full compression it may have clearance issues. I agree that if the spring is mounted ahead of the rear of the c-notch it should be welded and fully boxed.
