My 8258 Mod

[TinkerBrick]

Hi Folks!

This is just my 2nd post regarding something i'm building myself.

My dark ages ended about 14 month ago and the 8258 was the first "new" set besides the 8043.

The last lego set before my dark ages was the green code pilot truck. Good set, but now i have to learn everything new, since it is all studless now.

So, please be patient if some solutions to my mod are not as smooth or technically sophisticated.

During last year a added a couple mods to the 8258, especially Han's.

But i wasn't quite satisfied withe the outcome - Han's mod had dual wheel on the rear axles but only one differential. I found a solution to that at BrickShelf to set.

Anyway, i wanted a 5th axle really bad, and it had to be steered! I wanted it to be mostly remote controllable, but when it comes to driving, i wanted to keep the V8-engine.

I started on the a couple weeks ago. I adopted some ideas i found around the web (Eurobricks, MOCPages, Brickshelf, ...). I'll make a bibliography when the project is done.

Well, here is the first result. I set up a BrickShelf Folder: http://www.brickshelf.com/cgi-bin/gallery.cgi?m=TinkerBrick13

Separat Motor for the outriggers. Located above axle 3. Gear down with a worm gear, a clutch gear and bewel gears.

Axle 5 is steered, above axle 4 is a XL-Motor for driving.

Driveshaft for rear steering

Axles 3 and 4 are driven

What needs to be done:

Rebuilt gearbox to fit 3 more M-Motors to power the crane. And of course, a complete rewiring.

For completion i need a few more parts anyway, such as extension wires, LED-Lights and one more IR-receiver

I'd be grateful for any comments, suggestion or ideas.

Regards,

good so far^^

Do you put the original arm onto the truck or do you make a bigger crane?

@ DLuders:

Many Thanks for Deeplinking the images.

@ dfs473:

For starters i'll set up the original crane, although my mind boggles with setting the up the extendible part of the structure with micro motor as well as the winch.

I Don't know yet were to place the small AAA battery box.

But first of all, i need to fix the gearbox for turning and lifting the crane.

Nice work! I did not know you could RC this set. I really like the steering design.
