Backhoe Contribution – adrian2301 – Chassis/Stabilizer/Fenders and the Engine. And the hydraulics for the swing frame.

I think your lines maybe slightly bigger than mine. The depth on the bevel for the curve I used is 0.5″, which is radius , as @blanchsb ‘s knowledge he shared. Cant remember what you used but I think adjusting the size of the joint, nut, union, not sure what it’s called, where yours meet mine might be the best option. I have increased the diameter of the centre as much as possible without increasing the size as a whole, but I could If needs be.

Also I noticed the way your lines come from the loader arm where the turn towards the swing frame , the best location for each to avoid collisions would be the outer line to bottom connector, outer to inner line – bottom to top connector on each side. Does that make sense, not sure it does. The two outer lines to the two bottom hoses , next two lines from the outside to the next connector up, and so on. OK I’m sure you are smarter than me and know what your doing.

@adrian2301 dude, that is outstanding!  Really, I can’t stop staring.  I wish I had access to the 3D model so I could have a look all the way around.  

I’ve been so nervous that this part might be left unfinished because of me, but those fears are completely gone now.  Thank you so much for taking up my slack!

[Adrian Bellworthy]

Thanks @jakeblended , just continuing your good work.

Some more shots for you.

I had to read this several times before I got it. Worth it 😆

[Kent Trammell]

I connected my lines easy enough:

Our minds must have been telepathically linked because I took the exact approach you described! Also had to decrease the cables end control point to 0.9 radius. No one will ever know ..

[Jake Korosi]

Now just for the sake of theory – how would one go about rigging this for animation?  Of course the hoses are folded into those very large “wings” to allow the slide part of the swing frame to, well, slide from side-to-side across the back of the chassis.  I’m trying to figure out how a rigger might set up those hoses to deform properly and it’s just not coming to me.

Kent’s lines, leading out through the back of the swing frame, would be easy enough with like a simple deform modifier or a lattice I should think.  To save time, perhaps Wayne might decide to only rig the swinging capability of this part and not the lateral-sliding capability – after all, I’ve looked high and low and never once been able to find an actual video of the thing sliding.

I’m sure the master animator @waylow will have a trick or two.

Today’s progress: 

The cable and assembly for the boom lock hook:

and the swing lock and holder:

Adrian you already won the Oscar for best motion picture, you got a #1 hit one the radio, you won gold on the Olympics and you married your high school sweetheart. I think you might be on the verge of discovering what consciousness is and curing cancer.

[Jake Korosi]

Masterful!

Looking through my reference photos, I’m pretty sure the only thing that’s left for this component is the grease fittings.

[Wayne Dixon]

Yeah, I know a few tricks, but they always depend on the circumstances.

If all those cables are curves (and not geo), it will be easier to rig the curves with hooks to some bones.

If it’s a cable or something that an animator won’t need to animate, you just need to figure out a way to make it behave w/o the animator needing to touch it.  So the solution could be really simple,…or super complicated haha.

[Adrian Bellworthy]

Drilled some holes and added the Zerk fittings, (grease fittings, to us earthlings).

And I think we are done with the swing frame assembly.

[Adrian Bellworthy]

@dostovel I haven’t got round to curing cancer yet but I have discovered the true meaning of life.

[Ingmar Franz]

Looks really beautifull! I enjoy seeing all these details like the grease fittings 👍!
