My Sombrero Fix

Here are some pics of what I did to fix a sumbrero after the nut stripped. I tapped the original hole for 1/2” and extended the hole through the top of the sumbrero. I can now put a washer, lock washer and nut to lock the all thread stud in place. The allthread stud threads through both the bottom of the sumbrero and the top. To do this you have to tap both holes together in one session to make sure the threads line up for both holes. I’ll drill out the disc when the crossmember goes back in and I should be able to torque the nut with more foot lbs than what I could with the original stud set up.

One last photo of the nut, lock washer and washer I was able to fenagle onto the top of the stud. This locked the stud in place and keeps it from spinning when you torque the bottom nut.

You know its not that difficult to remove and replace the sombrero’s.
Drill out about 8 spot welds and then rosette weld in the new one.
It took all of about an hour to do.

I don’t weld yet and having someone come to the house was more trouble than how I ultimately solve my issue. It now has 1/2” studs that are secured in the original position as the old bolt, as well as the top of the sumbrero and it has a nut holding the stud tight. My new concern was collapsing the sumbrero with too much torque. I plan on building a sbc 420 for this car and a little over engineering was a better solution for me. But yes, you are correct. I priced sumbrero’s and for someone who can weld it’s not a difficult fix.
