Volvo G990 Grader

[Stefan]

Thank you Emil, Jack and Dan! Yeah, trying to keep it scale. 3D printing takes you a long way, but you still see the layers. Suppose some careful grinding could take care of that.

Now, machining of the lift cylinder arms has been almost completed. Just need to fill out some shrink holes (and grind out the layered structure :p).

Drilled and reamed to 14 mm.

The indexing lock pin mechanism (still to be made) will be attached on the rear side of the plate with the "key hole".

Amazing!

[Northern Farmer]

Some serious fabricating skills you have my friend!

[D8R]

Piece of art!

[jack van]

so i hope you have been makeing atleast 10 of each part because i am sure 9 other people besides myself would realy like to be your new best friends lol;):lol:

[Themonty73]

Wow, this is amazing work, keep it up it looks fabulous, mail I but one of those friends that gets a completed version grader PLEASE

:jaw::jaw::bounce::bounce:

[Cooper]

I have always wanted to make a model as close to scale as possible. I'm more oriented towards the mechanical workings and trying to relate that to our scale versions. I know you have a tremendous amount of hidden work, set up, jigs, precision measurements, ect,,,,, but this is really paying off!! Very nice!! An inspiration for me when I think it can't be scaled down.

Looks really really good Stefan !!

[Klebefix]

Nice work

[tc1cat]

Outstanding work!!! What are the extra 2 holes in the covers that you just made for? Could they be for jack bolts to remove the covers with? Just a guess!!!

[Stefan]

Thanks very much guys. Yes, Lynn, you are right. Those covers sits quite tightly. The specification says "blade down force capability 11 058 kg (24,457 lb). Don´t think the screws alone would cope with that for a long time (guess the real screws are 1/2 inch dia.). I use M1.6 (about 1/16 ") in the model.

[Stefan]

Found some additional pics which should have been posted a long time ago :o Some caps and screws added.

At the bottom right you see scrap parts from the spherical bearings from which I extracted the balls and the bearing inlays.

Stefan

[Doggy]

This is fenomenal!

[D8R]

What to say:)
and at 5am, you must be kidding Stefan.

[Cooper]

Nice work on the bearing extraction.

[Stefan]

More than overdue as the old cloud provider disabled the direct picture linking :mad: (luckily the old links are still valid). In the meantime the indexing bar and (all) cylinders were finished.

:jaw::jaw: WOW!!!!! Looks terrific! Only thing is, where are the grease fittings on the bearing blocks???


Just kidding! This is one outstanding build.

[Stefan]

Thanks Lynn!
The grease fitting seats are at the arrows. They just haven´t been fitted yet. The central grease hole is barely visible in the next pic.

Not kidding ;)
Stefan

[tc1cat]

You just got elevated to a master craftsman:jaw: I was looking more for a grease fitting in the bearing block not the ball joint itself. What other thing have you put in this work of art that you haven't shown us yet?!?!

Second thought- you are way above a master craftsman!!

[TRUCKMAKER]

So why can't I see the pictures, Lynn you got x-ray vision. Been following this from the beginning, first time I'm not seeing it?!

[AbelVincze]

Me neither... Whould be good to see these pictures too :)

[tc1cat]

Nice clear up close pics!! No idea why you can't see them.

[sparkycuda]

The build is well beyond my imagination. Just can't believe this is a model. Amazing craftsmanship!

Ken

[jack van]

do you have any pics of the whole model thats is together would love to see model as built so far

[AbelVincze]

(changed browser...) Very nice details, congrats again!

[Bo Wallen]

Oh lordi lordi ......When awesome goes Brilliant .....:) Just waiting for the miniature grease gun to be made.........:D

P.S. Grader is on my must have item list.

[Stefan]

@All: Thanks a lot for the positive comments.

@Lynn: Ok, I was kidding a bit :o The grease fittings will not be operational - but coming to think of it... :D

@Kent: Hope you can see the pictures now.

@Jack: Yeah, haven´t had it all put together for a long time now, so think that would be a good idea. But no such pics at the moment. Sorry!

@Bo: Hopefully someone else builds the miniature grease gun :D Maybe some day in a very far future my second grader will be for sale ;)

Stefan

[jack van]

if this is a 1/8 scale what do you expect the final weight to be around

[Stefan]

Simply based on scaled down real weight I estimate it to be at least 40 kg. Extra implements like ripper and front blade not included.

Thanks Stefan, yes I can see them now! Its looking good, I don't always comment but I'm always watching!

Sorry guys, simply haven´t got around to posting anything for a long time. Also didn´t do so very much on the build.

In November I noticed that most picture links were broken :mad:. The original photo host site had been taken over by another one and the pics transferred to the latter. In the process the original URLs went dead. Luckily, this forum allows editing for apparently eternal and so I managed to edit in the new URLs having first identified the picture of each broken link (over 300 of them :() by opening the HTML source code in the browser.

Concerning the build I did manage to shape the plates for the fuel tank (which will serve as the hydraulic oil tank) and make parts for the circle bearing. Also made some progress cutting a lot of screws to correct length and making scale washers. The cut screws allowed me to put some of the sub-assemblies properly together and, remembering that Jack asked for pics of the whole model, I´m happy to now be able to post some overview pics.

Outstanding workmanship and skills,I fortunate to have found this site, Thank you again,Catpusher

[Zabco]

Fantastic work! The level of detail is amazing. Thank you for sharing.

[Azonic]

Pure art right there!

What's the dimensions and weight of it this far?

[mitschka]

amazing!!

[Stefan]

Thank you for all the kind comments!


What's the dimensions and weight of it this far?

Length.. 121 cm (47.6") over all
Width..... 34 cm (13.4") at the front hubs
............. 31.5 cm (12.4") at the rear hubs
Height.... 39 cm (15") to the upper end of the lift cylinders (as propped up on the Lego).

The weight is almost 26 kg (57 lb), this number includes the blade and the tank which are still unattached.

[Lil Giants]

A great set of pics Stefan showing your extraordinary craftsmanship :cool:

Lately bought some CAT models in 1:50 and put them side by side with the Volvo grader* for comparison. And I who thought I´m building something big... :rolleyes:

*) The G970 is just some quarter meter shorter than the G990 and the tires are typically 17.5x25 vs. 20.5x25.

[ederson]

sou do brasil e sou fã do SAIT gostaria muito de ver um video deste seu modelo e parabéns pelo belo trabalho

[frizzen]

Awesome, with the beautiful job you've done so far on this, i can't wait for your starting on a 657G bowl scraper.
