Update: Jason from LDO had confirmed that the frame is NOT powder coated, but that the surface is anodized. The practical concern about the surface feature holds, but I wanted to make sure that I set the record straight
—————————-
Some SUPER nit-picky thoughts on LDO’s frames: I’ve built four of LDO’s frames at this point, so my experience is limited, but I did have a few observations that I’ve been rolling around in my head. First of all, the frames are excellent! No doubt about that! The V0 frames I built (I’ve built three of these frames) had a smooth surface finish that I THINK was a dyed anodized coating. It was flat, and looked great. The 2.4 frame, on the other hand, had what looked like a lightly textured power coated finish. It looks AMAZING, and seems to be pretty durable. I banged a tool into the side of the frame in a way that I fully expected to have damaged a painted or anodized coating, but I couldn’t see any damage to the powder coat. It’s VERY well done and looks like it will be a durable finish in the long run. I like it!
However, because the ends are machined and tapped prior to coating, it means that the tapped holes are looser than I would really like (to leave tolerance for the coating), and the mating surfaces of the blind joints are textured. For me, this led to an ever-so-slight misalignment in a corner. I was able to twist and turn the parts a little to get them to mate more squarely, but this was a SLIGHT concern for me. I love the look of the parts that have been coated after being cut—the ends look so much better than bare aluminum. but this means that the ends may not be perfectly flat due to the texture of the coated end mating with the texture of the side if the vertical supports. With an anodized coating, this isn’t an issue since the anodizing doesn’t change the geometry by enough to impact the squareness of the frame, but with the powder coating, there is some chance that the corners won’t be square. I’m honestly not sure what to think about this since I have a sample size of one powder coated frame, but I can’t get this out of my head that it may cause a squareness issue at some point. I seriously doubt that it will large enough to impact functionality, but it’s something that I would keep an eye on if I were using a frame with a textured surface finish.
Aesthetically, the powder coating looks phenomenal and appears to be durable (again, I’m assuming here—it may not be a powder coating!). I, personally, am fine with fettling the mating surfaces to get parts perfectly square. I’m just thinking out loud about other builders who may not be as aware that there is a potential for things needing a bit of TLC. I think I’m being overly concerned here, but I’m writing this down just because it’s been in my head for a day, and I needed to get it out. Ok. Done!

TL/DR: The coating on the LDO frames sure is pretty, and appears to to be durable! Make sure that you square it well.
