ARTech welded steering pinion compared to another
Truth!

I'm in the process of depowering the rack from my 1997 car. I'm going to give the Loctite 680 a try. If it fails, then I guess I can just clean it up and have it welded like everyone else. If it works in the long-term then it may be a viable option that we can recommend.
Here's a question though: Does anyone know what the actual diametral gap is between the two parts of the pinion shaft? I'm trying to decide whether or not to use the activator. It is recommended if you are near the gap limits for the retaining compound, but indicates that the ultimate strength of the cure will be slightly lower than if cured without activator at closer tolerances.

I did try it and the rack is reassembled, but I still haven't gotten around to swapping it back into the car, so I haven't yet had opportunity to test the effectiveness/longevity of it.
Application is the original JKC power rack out of my 1997 NA.

Thought I should chime in. Thread on m.net from '09

"I soaked mine in degreaser then soaked it in isopropyl alcohol, blasted with air nozzle to get rid of any residue.
I have my welder proceed in alternating segments like torquing a lug. Done in one continuous weld can warp it. Ask me how I know that
Not the kind of thing you give to any one but an absolute expert welder with the correct equipment for the job."
For those of you concerned with the potential for catastrophic steering failure with welded input shafts, I'd suggest reviewing the incidents that have occurred. Only there haven't been any with several hundred Miatas with probably an accumulated 5000+hrs of abuse with race tires.
One of the pinions my welder did back in 2008. We still do it the same way
