Collab 2020: Modeling Heavy Equipment (Backhoe)

[Omar Domenech]

I looked up the Russian translation, he is saying “And be careful here, it’s a tricky modeling shape around the corner, let me do a close up… check this panel here, who ever has to model this is screwed, this buttons here you don’t have to model them in one piece. Anyways DOG Pound, we are counting on you”.

But it’s only been like 2 days Karen. Or is this the coronaverse time acting up on me again.

Hahaha that’s awesome.  Our legacy is now indelible!

Just seen: If we pass the mark of 1276 replies then this will be the biggest CG Cookie forum thread ever 🏆!

@spikeyxxx Is there anything mathematically special with that number or do we have to take a look into the history books 🤔?

[spikeyxxx]

You can find something special about every number;)

If you double 1276 you get 2552, which is symmetrical (palindrome ).

If you put the outer digits ‘upside down’ and let the middle two switch places you get 1729 (Ramanujan-, or taxi number).

[spikeyxxx]

If we pass 1276, that means 1277 and that is 1233+44,

or: 12²+33² + 44,

or: (3*4)² + (3*11)² + 4*11,

which is kinda beautiful, I think.

[Ingmar Franz]

And why is 1729 a “taxi number”?

[spikeyxxx]

You can search for that, it’s quite famous.

In short: Ramanujan (Indian clerk, ‘uneducated’, but brililiant at numbers) was in the hospital and Hardy (English mathematician, quote:’ I do number theory, because that is the only part of mathematics that has no use outside of math’, or something along those lines) came to visit him and said ‘I came here in a cab with number 1729; that is such a boring number: I hope it’s not a bad omen.’

Then Ramanujan thought for a few seconds and replied: ‘On the contrary: 1729 is very interesting: it’s the smallest number that can be written in two distinct ways as the sum of two cubes’ (Namely: 9³ + 10³ and 1³ + 12³)

[spikeyxxx]

Here’s one I didn’t find myself:

Let n[1] = 2 and n[m] = 1-n[m-1]*3, then:

n[7] = 1276.

[spikeyxxx]

There are no uninteresting natural numbers, because if there were, then one of them would be the smallest uninteresting number, making it an interesting number. Proof by contradiction.

hi guys! aim back

@spikeyxxx Sorry for the delay but I finally linked your mastered wheels into the assembly. Everything looks good from the outside but hubs appear too wide or offset on the inner side (?):

[spikeyxxx]

@theluthier my hubs are (relatively) fine:

The inner ones are made by @duerer and the fit his rear axle, which is a bit smaller than my front axle.

There is a discrepancy that has to be resolved!

Is my axle too wide?

 Is the rear axle too small? 

Are both axles correct and are the rear wheels closer together than the front wheels? 

None of the above?

I will look into why I put my wheels there, but I will not make a decision on what has to be changed, on my own;)

[Adrian Bellworthy]

If you don’t mind my opinion, I think @spikeyxxx has the correct position with the wheels and axle.

This is top view from master assembly file:

If the tyres are moved over to @duerer ‘s wheel we will have a collision with the fenders and the tyres with @blanchsb ‘s loader arms, and they are already tight with the engine enclosure.

and the fenders at the rear also match the position of @spikeyxxx ‘s tyres:

Sorry @duerer , I also have another issue with the rear axle.

I was able to adjust the height of the chassis over your axle where it will attach, but I can’t move in the x-axis without more collisions with almost everyone’s parts.

But the good news is I have sized and aligned the driveshaft with your axle.

[spikeyxxx]

As far as the front wheels are concerned, I can rotate them (steering) about 15° in both directions. I can’t say how much this is:

but I doubt that this will be possible when I move them inwards…

The easiest solution would be to move the back wheels inwards to fit the rear axle and leave the front ones as they are now..is that correct? I don’t know, but it might be when looking at this:

or this:

Really hard to tell…
