The shock mount being off center (and I'm seeing some slant in the sides one of the mounts) is definitely a defect and is covered under warranty. We're good, but things slip through occasionally which is exactly what our warranty is for. I don't have a new set of A-Arms to swap out for you right now, so we'll need to handle this as a rework. We'll take care of the shipping costs and all. Also, what I'm seeing in your pics with the weld consistency should be better. Looks like the arm was flipped over after different passes.
You're right, it's not a technology problem or something that is inherent to the process. I think someone was having a bad day, which ultimately is my responsibility.
As far as the tech and equipment goes, yes it's top notch. These are my welds on the same Lincoln 255 welding machine. But this is not what I expect in production.
This (below) is what I expect for consistency at a production pace (also my welds, but from 2014 or so). Consistency of the welds is noticeably less. Also look at the splatter on the insides of the spindles (which we do not remove, reason below).
Now bringing it back to A-Arms, this is what our typical production A-Arms have looked like over the past year, through 2017.
About your other points of concern. I get where you're coming from, but there are a few things to keep in mind...
1. Inside paint: When you say that the insides are unfinished, are you referring to the inside of the pivot tubes? They aren't supposed to be painted inside as that area should be greased like the originals. The bushings are self-lubricated for longer life, but greasing the inside of the tubes/bolt is still recommended.
2. Spatter: Knocking off small weld balls is strictly forbidden in the shop. I've found my guys spending hours
of time picking off welds ball on parts. Taking 2 or even 3 times longer than it took to weld it in the first place. The money this sucks out of the sale seriously hurts my ability to keep these items on the shelf.
And in the end, the part looks molested by all sorts of wire wheels and flapper discs. Paint can't hide it.
With that said, if there is an unreasonable amount of spatter on a part, it goes back for cleanup. That usually starts a conversation about being attentive to settings on the machine, pacing, and technique. But I'm not seeing excessive spatter in your pics. Looks about what I would expect (except for the large ball on the side), unless I'm missing something in the pics.
I've asked shipping to send you a return label so we can get these back for rework. You should have it in your inbox by now. Just a heads up though, for the quickest response on warranty issues (or normal CS support issues), I'm actually not the best POC. You'll want to call in, or use our "Return/Warranty this item" button on your order. It's a similar return process to Amazon's system. I'm happy to help facilitate personally (and definitely happy to clarify policy and how stuff works behind the scenes), but going through me for the return itself adds an extra layer to the process.
