178 axle support

   StephenH, it doesn’t need to be attached to the axle, it will be pressing down from above. 

The reinforcement I did has to be u bolted because it’s on the bottom. 2 different ways to skin the same cat. 

Toyanvil, just for comparison, my axle crown is only 1/4 inch and I don’t have any noticeable negative camber. StephenH’s brand new axle only has 3/8 inch crown. Those are with the trailers on their wheels. So just from looking at how much negative camber you had, I’m wondering if your axle tube ends were bent at the attachment points while you still have a little arch left in the center?

	How do you intend to attach this to your axle? I don't see enough space on it for U bolts. Drilling through it and bolting would work since the place where it would attach would be the same place that the internal part of the axle would need to move for your suspension to work. Even drilling and using short screws would not work since the screws would also very likely interfere with the internal movement of the axle. Welding it to your axle is also not feasible as it would cook the rubber inside that provides your suspension support. The slideshow on the Lippert page shows what a cross-section of the axle looks like in the 5th and 6th slides (see dots below picture). https://www.lci1.com/torsion-axles#about Edit: I got to thinking more about this and it might work but it would require modification of your design. In brief, add wings to each side of the bracket and then either use a "V" bolt or fabricate another section of channel with similar wings to the top piece and then use bolts through the wings to attach the bracket to the axle. Here is a line drawing of what I think would work (I don't claim to be an artist):

	When I am all done with the supports I will have it re-cambered and have the alignment shop preload the adjustable links a little. The only thing I found with the axle was it had lost it's camber, it is now almost flat with less then an 1/8 inch of arch.

	Toyanvil, looking good. Were you able to get the axle recambered? Was the axle tube being bent the only issue you found? Thanks

	Thank you, I just hope it works. My hobby is metal working, so this is fun for me. I have been modifying my 1961 Sunbeam Alpine for the last 42 years

	Now, that's some really nice work, Toyanvil. Uh, er, we're going to be passing through B'field on the way to L.A. in April or May. Would you mind throwing together another set? Just kidding, but it looks like FR may want to work out a deal with you for the newer Pods. I hope you've talked to a patent lawyer.

	The bolt with the spacer is there to hold everything in place when welding. Worked on it today and got the axle mounts about half way done, still need to make some more parts and then weld it all up and powder coat them. Next will be the adjustable link that will go between the two mounts.

	Really looks great. Can't wait to see the finished product.

	funks, Toyanvil isn't done yet. The support brackets still need to bolt to pieces extending down and out to support the axle ends. Looks great so far though.

	Welcome to the group. I really like the support your giving the axle. I hope it works for you. I have one question to ask. The picture of the support were its lying on the vise you have a bolt with a spacer. When mounted on the rpod you just have the holes without a bolt. Why are the holes in the support? Thanks for sharing.
