I appreciate the encouragement, folks. Part of my motivation for starting over is that getting a working QA has always been my secondary goal. My primary goal has always been to hone my fabrication skills. The incorrect spacing of the side plates, and the fact that the side plates are way out of square, is an indication that those are skills that I need to work on. Getting your finished product to the intended dimensions and alignment is a pretty basic fabrication skill. If I was to have a shop teacher looking over my shoulder, he'd be saying, "Grind out those welds and get it right," not, "Ahh... it's fine. Go on to the next step."
Yeah, getting a working QA is in there somewhere, but for me, at this point, the number of mistakes has crossed a threshold where there's too much opportunity to continue to learn. I'd really feel like I was letting myself down if I just charged ahead and produced a finished piece that was full of mistakes and that I couldn't feel proud of. If I thought that I couldn't do any better, then I might decide to just git-r-done, but I know that I can do better.
I do hope that the lessons I've learned so far are helpful, or at least entertaining to others.
If you're having this many issues your money is probably well spent just buying an SSQA quick attach and being done with it. I know my time is worth something, Im sure yours is too. That titan attachments on here is selling the pin boxes pretty cheap, all you'd need to do is cut off your bucket ears and weld those onto the pin boxes then of course weld the SSQA plate onto the bucket. I didnt have this cheap of an alernative when i built my quick attach, if I did I would've went with the ssqa right off the bat.
Thanks. I'll look into that. SSQA would, of course, be preferable to pin-style QA. If this project ever crosses the line from, "learning experience in fabrication," to, "I just want a QA right now, darn it," I'll look into it. I'm not too worried about the time, because welding and fabrication is currently just what I do for fun. So if I wasn't doing this, I'd be sitting in front of the Xbox. The money I've spent on materials is a little harder to shrug off, but this has been a lot more interesting that welding coupons, so it's probably still money well spent even if it doesn't produce a working QA at the end.
