Is this a wild idea? De-power pinion idea
So I'm in the process of de-powering my rack. I'm at the "Do I weld this pinion and screw it up, do the pin method, pay a professional, or do nothing and roll the dice if I notice any slop" stage. For my own track car, I'm just going to pay someone to TIG it. I can also TIG weld but I'm a YouTube welder, not a pro.
But this got me thinking, would the community be interested in a drop in solid one-piece pinion? I'm thinking I'd send it out to have the alloy & hardness confirmed, then 3D scan it -> model -> CNC. I'm a software engineer by trade so I'm definitely out of my lane on this, but I could probably orchestrate this into existence if we think it's worth doing?
Just sort of an off-the-wall idea. Also, hi I'm new here and I ask dumb things like this all the time

If you don’t mind the car being down a few weeks, you can have it welded reliably online:

I had a good experience. Everything said and done, with shipping, it’s just under $100.
It’d be awesome to pre-buy a core to swap in and speed up a Depower project. But you usually have to buy the whole darn rack.
As a one man operation, that’d be a lot of work on your end.
I wouldn’t stress over a welded pinion that much. Hindsight, it felt like a lot of work for very little return. For me, it tightened a little slack, but some was still there. Do it because YOU will be happy about it. If you don’t do it, your brain will compensate and get over it.

If I hadn’t had my pinion welded already, I would’ve sprung for an off the shelf option/replacement.
You probably won’t notice the slop from leaving the pinion un-welded. You will likely notice the steering is tighter after welding the pinion, though. At least that was my takeaway after having run a depowered rack both ways.

CNC with hardening, etc... I can imagine would cost what a completely done rack costs...or more...just for the one piece. For what advantage?
My local guy charges $300 for a done rack and he does a spectacular job(tig pinion, shave tube, paint, etc...). He has racks on the shelf generally.
Edit: local guys prices went up....450 for depowered rack plus core...
