I know there are far more intersting things in your life than wondering what I'm building next but since you ask it'll be Jurgens Ultimate 42082 and as I finished the 42030 yesterday (to be posted shortly) building will be starting soon.

With that in mind you may want to ensure your next haul is a long one. Make that a very long one. It's a big build 

Well Given that we just wound the clocks back on the weekend, and it has got a bit colder at night ( Puttles is now sleeping in the bed instead of on top ) you could say winter is on its way...However due to circumstances beyond my control I have had a change of career ( got married as well ) and have a little more time on my hands, and are home at night.

And besides I quite enjoy Grum TV ... the show is pretty good.

[grum64]

Congratulations on getting married. I wish for you and your Wife to be as happy as me & Mrs Grum because if you are then you’re going to have a really great life together and one heck of an adventure.

Hope the career change works out and is all you want it to be.

Building Time 5hrs 20min - Total Build Time 5hrs 20mins

This post is very photo heavy. Sorry.

After having had a fun filled week with the Little Darlings they've now gone back home  so it’s time for another build to begin.

This time it’s the 42082 Rough Terrain Crane only it’s not, not really. This is Jurgen’s Ultimate 42082. Out of the box the RTC’s a great set but Jurgen’s version being full RC is so much more playable. Full RC means fitting 6 motors, 2 servos and an extra battery box into the model which seems unlikely but Jurgens done it.

The first job was to get the parts emptied into a sorting tray which was a good idea in theory but 4057 parts in one, albeit big 120cmx55cmx5cm, tray turned out to be not the best idea I’ve ever had. Being full to almost overflowing sorting parts out was nigh on impossible without a tidal wave of parts cascading over the edges. After getting the huge pile of parts divided into two trays it was time to start building.

So far the build has gone well with just the marriage of the two large sub assemblies being the fly backstroking it’s way through the ointment. With the universal joints being more wiggly than even the wiggliest of wiggly worms, stopping it moving about while trying guide it and the other axles towards and into their respective destinations proved to be time consuming and very frustrating. Aargh.......

Wow quite impressive how densly packed with functions that assembly is so far, looks like great fun. A minor thing to keep in mind, for future assembly of multiple universal joints, line the slots up on the U-joints so that they are on the same spline of the axle, you will have smoother operation. This is how it is done on real machinery.

Like you, I'm amazed how much is being fitted into the available space. It's an interesting build and one I'm learning a lot from. Learning while having fun, just how education should be.

Thanks for the info on lining up the slots on the universal joints. It’s something I'm well aware of but, along with many other things, often forget to do. One too many knocks to the head over the years I'm afraid.

You are on a roll my friend.

And I hate to bring it to you, but @Johnny1360 is right about those U-joints... The angular motion of the straight axle will be ever so slightly non-uniform. Luckily for you you made the mistake on both ends of the axle, so it is only the middle part that is not moving perfectly. So I'd say, no harm done this time

Thank you Jeroen. It's been a really enjoyable build so far.

I think I'll correct the middle part of the Universal Joint anyway if I can. Jurgen put a lot into designing this so the very least I can do is build it right.

This is new to me, but I'm not sure I follow. The straight axle you are refering to appears to be the only one where the slots in the U-joints are aligned, yet you say this is the axle that will not behave correctly. Do you mind clearing this up a bit for me?

If both U-joints aren't following the same alignment, the axle will rotate in a slight circle rather than simply rotating on the spot. I've seen it happen on my 42029; luckily, I was able to correct them without taking anything apart.

This is because there are two non-aligned U-joints leading towards that straight axle. And the input is before the non-aligned U-joints.

Building Time 7hrs 15min - Total Build Time 12hrs 35mins

After several chaotic days it’s really good to have some time to build.

Before going any further I must apologise for there being no photo of the second axle assembly prior to fitting.

Now, I could blame Jim by saying I just copied him as he didn’t show the second axle assembly in his excellent review of the 42082 because apart from a couple of differently coloured parts it’s pretty much identical to the first and that’s how it is on this build. I could blame Jim but I won’t (more like daren’t!) as last time I ‘messed’ with our esteemed leader he added Old Fart to my profile! 

Truth is I was so focused on building it completely escaped my tiny little mind to take a photo before fitting it to the main assembly. I would like to have had one if only for my own build album but hey ho, it’s too late now.

Building’s gone really well in this session with the few assemblies etc I thought likely to be problematic proving not to be so.

The side storage cabinets on each side of the 42082 have been sacrificed to make way for the batterry box (88000) and Sbrick but to keep this Ultimate version looking the same as the LEGO original the doors remain. Fitting the door (which conseals the on/off button) on the battery box 'enclosure' was a pain to say the least but as I went on long enough about fitting one on my last build, the 42030, I'll spare you from me boring with it all over again. It’s done and that’s all that matters. There’s another one to fit on the opposite side. What joy.

Speaking of the other side. The Sbrick and accompanying spaghetti like tangle of cables caused me over an hour of grief. I had difficulty keeping the cables out of the way while fitting parts around them which was a touch frustrating. When bunched up, the cables are quite ‘springy’ and when I try move them out of the way with my stupidly static fingers it’s they that move not the cable. Mr Universe I’m not! Anyways, the parts are on and the cables tucked (not prettily!) inside & out of the way.

Unless I’m mistaken, in which case I’m a klutz, when all four ports are being used on an Sbrick you can only stack extra connectors on the upper two. I’ve used Sbricks in several of my builds and in many of the weird and wonderful contraptions Jake, George & Penny and I have built together but I’ve not had cause to stack connectors before now. With this build the Sbrick was going into a confined space but the stacked connectors sat a plate or so proud of the bodywork. Removing from it’s mounting allowed it to be moved back just enough for it to sit flush. I just need to sort out some 1x2 Grille pieces to help conceal it a bit.

Sorry but a lack of time means this is just a quick progress update posted now so as not to make the next post too photo heavy.

I’ll do a write up if/when I get chance.

What, orange fans not good enough for you, Grum? 

Seriously though, this puppy is gargantuan! Not to mention it must weigh an absolute ton with all the motors ganged inside. 

[grum64]

I couldn't bring myself to fit the orange fan. I just couldn't do it, it's an abomination.

As for the size. Yep, it's a biggie alright and is indeed heavy, more so than I thought it'd be. It's going to be getting much heavier though as there's the superstructure still to build with it's 3 motors and a battery box and then there's that big ol' jib.

A couple of days building with I feel good progress made.

I'd have gotten more done were it not for me making a couple of silly mistakes which, although only minor, were time consuming to put right.

Somehow I could not feel that V8 is best choice for RTC.

Nice progress Clive

Thank you my Friend.

I did consider reducing the cylinder count by 2 but as you know, I’m such a fan of building LEGO engines, especially in V configuration, that I didn’t want to deprive myself of all that fun .

Truth is I did consider changing the engine to a V6 but I wanted to keep the builds appearance as close to the original as possible. I know I replaced the orange fan with a grey one but there’s only so much original a man can take .

Edited May 26, 2019 by grum64

[1gor]

One day I'll make some (mobile) crane, but it would have engine as original...probably ome Liebherr version in DBG / yellow combo. But in the meantime  I have to relax (even from LEGO building)

Kind regards

Happily building's been problem free so none of my usual ramblings are needed.

The axle is only temporary. It’s just being used to stop the LA’s shortening/extending during the fitting of the sub assemblies.

Yellow liftarm is only being used as a prop while taking photo

Great progress Grum.

I would just give a small recommendation to improve the mod of the set. Put some kind of a stop on the 3L axle with stop inside the portal hub, to keep it from sliding out of the 8 tooth gear and the universal joint, something simillar like 9398, 42030 or 42070 have.

Thank you my Friend. The build's going pretty well.

Thanks for the heads up. I'll have a think and come up with something to keep those 3L axles in place.
