Collab 2020: Modeling Heavy Equipment (Backhoe)

[Parker Bourassa]

@blanchsb Yours is looking so good! Am I on the right track with the connections?

[Kent Trammell]

@pfbourassa @blanchsb The collaboration between you too already is awesome! Both of your level 2 blockouts are looking sharp too. Excellent work so far 🤜💥🤛

[Shawn Blanch]

@pfbourassa yeah that is looking great!

[Shawn Blanch]

Okay here’s my updated loader arm progress. Made lots of holes and filled them with pins. Tried to maintain somewhat of decent topology for next stages around all of the holes and details.

[Kent Trammell]

Really nice work @blanchsb! I’m wishing the next stream wasn’t a month away…seeing you and @pfbourassa do work is making me impatient to continue the project!

I can’t add my name to the list for the stabilizer.

[Parker Bourassa]

Make a comment(CTRL + ALT + M) , and Kent can add it later.

[shan jay]

You added it already

[Kent Trammell]

@az93 Sorry for the confusion. As owner of the document, I’m the only one that can enter info into the cells. But you can add a comment to cells that are like a mini conversation.

So you know, I received your comment and added your name to the stabilizer 👌

I just noticed my piece is one side a battery box and stairs on the other. No symmetry for me. It seems to me the people that designed this thing knew I was going to get this part and made it so I couldn’t use a mirror modifier. Thanks industrial designers.

@theluthier Kent how does this work now? In the sense that I don’t know if I upload the modeled piece to Drive, is it like a submission and I can’t undo it? Or can I upload it and you take a look and see if there is stuff that I need to change and I change it?

Here’s the Drive link. I tried to make it that only you can see it but seems I didn’t know Gmail.

Ok I am hitting a decent snag where reality clashes with reference. I wanted to get some community feedback/critique on my thought process.

The lower hydraulic does not seem to fit based on the reference angle it is shown at

I know the proportions are correct because I rotated the main loader arm in order to figure out the location for the lower support and also using a common reference bracket for it’s location.

So, I just rotated everything and lined up to make sure I got close enough and I think I am going to push on with using the Red Dashed line (on the first image above) for where the hydraulic is supposed to go: My only concern is tire/wheel clearance where the main frame connects to the tire/wheel. Maybe I need to collaborate with @spikeyxxx  as well since he offered the wheels???

I’m going this route I think. The lower support is about midway along the loader arm and that would make most sense for load-bearing support while it is cantilevered in the air holding a “load”

@theluthier @blanchsb @pfbourassa 

As far as I can tell from the reference pictures, thos two, ugly, additional pieces on the loader bucket are on all the pictures and seem very functional to me, although I ‘m not sure what they are doing, I read them sort of like this:

So they can be put in different positions…

[Parker Bourassa]

@blanchsb Are you saying the piston doesn’t seem to point at the part it needs to connect to in the drawing? If that’s the case, I’d say to follow your intuition, it’s probably just a mistake in the illustration.

Or are you saying there isn’t enough room between the tire and the body for it to fit? That’s trickier, because it looks to me like you are on the right track.

[Parker Bourassa]

@spikeyxxx My interpretation of this front area is that the base model has this rail going across so the user can add or modify the bucket to do any number things, and this particular reference has these metal bars attached because it’s a function they needed.

I could totally be wrong about this, but if they are added by an individual owner, I’d rather not include them in our model.
