DOG Manufacturing Group,
I need your advice on this part of the bucket. I think I have this side correct, but there isn’t good reference for the opposite side of this should be shaped like. The part “inside” the bucket.
Should I just solidify this section? It would interrupt the bucket’s otherwise smooth shape inside.
Here’s what I mean, it doesn’t seem right, but for the back to function it kind of has to be this way?
Maybe these “innards” are hidden by another sheet of metal, so the bucket can stay smooth?
I’m hoping there’s an obvious solution I’m just not seeing.Everyone’s pieces are looking so nice!

Here’s my best guess at the moment: https://drive.google.com/open?id=12bhYTqrethkOiKs8j0Vl65yilf8usuX2
@pfbourassa I downloaded you file. That part is one solid piece up until it mates with the Hydralics where it “Forks” out into two tips. Take a loot at the Schematics link that Kent posted at the top for each part.
I found some similar bucket designs. I am willing to bet that they all share the same basic parts (manufacturing practice is to copy parts when possible)
Also here is a decent back-shot of the bucket we are most likely going to try to replicate (With Forklift Forks Included!)

Ok. I need some hard surface modeling guidance from the gurus of the group. I am having a hard time making smooth and crisp transitions from square/hard edges to circular topology. Three instances on the loader arms are causing me grief and I am unsure how to proceed. It acts like the Bevel is “bleeding” over areas where it shouldn’t. I’m sure it’s an easy fix but not sure what it is and I’ve tried a few things but with no success. I think I need maybe some more supporting geometry or “holding” edge loops in more places but maybe it’s something else. It’s hard to add to the circular cross section parts to give more edges to them to work with and keep them circular haha. I’m dreading that is perhaps the solution.

I turned on the normal matcap because I feel like it highlights this best: Areas circled in yellow are where I am reaching the limits of my “crisp yet looks soooo smooth” skills. I have my modifiers ordered like so: Bevel (with weighted edges I pick, all set to a value of 1 and percent of bevel of 5%) then Subdiv with divisions set to 2. That mod stack seems to work to keep things looking smooth yet sharp, except in these places.

Hi Blanch, that is looking great!
About those problem areas, this is how I would do it (maybe not the best way, but I am terrible with Creases and the Bevel Modifier with Bevel Weight only works in some cases for me…):
Having edge loops on both sides of the selected loops gives full control on how sharp/rounded they look, without artefacts.
The round cylinder has 8 vertices, while the rectangular piece has 12, so you need a 4 to 2 junction on both sides.
I just did this small part and only on one side, but you get the idea.
Personally, I would not use a Bevel Modifier at all, probably and only work with holding edges, but that’s just preference.
Didn’t show it here in Object Mode, with Subsurf, but it looks just as good as the rest of your model!
As far as I know, the biggest problem you are having, is the 5-sided pole directly on the edge:
I basically moved that pole on a flat area, where it cannot do a lot of harm;)
