Decided to go out in my 33 ( not finished but drivable) for gas. Went about 50 feet when two of the steering shafts separated ( suddenly not drivable). I thought I had all joints tight with blue loctite. I am tempted to try red loctite but would like to hear of other solutions such as cutting grooves on the flat shaft surfaces to prevent the screws for sliding even if they become loose or drilling all the way through to install nuts and bolts.

Thanks
