Alasdair Ryan

thanks for all the help gays i can alway count on some one to help i rebuilt it all th time lucky heres a pic of the new undercarriage i used two Small bevel gears (you can see one) i ended up raising the slew ring Mount as well i also rebuilt the upper structurer as well 3 1/2 hours work (non stop a part from letting the blood recover around my leg because i don't work at a table, i will try to post a few more pics in a few weeks time i got laid off from my work in march so i can't make much progress on it as i am buying all the parts from brick link maybay i should get back on my computer and designed my next project

a 12 tooth gear will not go as i dont want the hight to be changhed

sorry about the title change if you want veiw file to help you

i have a worm gear on top of a 16 tooth gear and its slow as you expect i need to speed it up a bit any ideas,but i need high tork as well remember about the hight of a worm gear on top of a 16 tooth gear, you may need to moc something up

is there diff locks on that? of is that only for the steering, am not a fan of that belt is there any sign of it slipping under the wight of the finished model what about using some of the small chin links?

what about my idea yes you would need to get 4 micro motors but is is quite simple to build you could this idea to make telescoping legs as well simply by having the micro motor at the end of the 2 extension then run a extension wire inside simples

hold it there milan they also have a extra counterweight system the counter weight behind the front cab connects to the underneath of the rear ballast also they have a tilt cab and diff locks you need to include these in your model as well otherwise Jenifer's got a better crane, might it be better to scrap the pneumatics for the jacks and use 4 small actuator's you can then use four small micro motors transfer them into pf function by using short extension wires, then run axles to the end and use a worm gear system make sure you try and get as many boom extensions as you can other wise well you know......she will have a better crane ps remember the rotating becons and reversing beeper

crane nowadays you can change what axles steer i think in normal drive the front axle turns only,(look at file below for steering) i thing the tires you got on are a bit to offroady,you have left a bit to muck space between the two back axles you will need to move the axle a bit closer together look at file below for reference look at this, it is about the size you are hoping to build http://www.terex-cranes.com/en/idc03/groups/webcontent/@web/@cra/documents/web_content/ucm03test_001327.pdf

nice,maybe try and build a custom bucket witch splits in the middle or raise the cab a bit

it seems that this excavator has its problems as i i am building a custom one of my own i don't think i will rush to buy it

nice find

thanks for the help

hi all do any of you have ideas on making a power function pneumatic valve that goes back to center i have seen sariel or Nico's idea hope to see some good ideas from you

its to hold an axle bush

nice what you need now is a pf setup for vehicles , to change gears easy enough to do how ever it might be challenging to make a gear box that can side left to right as well as up and down

you can have more than three sections quite easily all you need is two pieces of Lego string the same length one for extending and one for retracting you should be able to pull on each one to get it retracted or extended. The trick is to make each section as thin and small as possible so you can fit lots of smaller sections inside each other.

Edited.

I am building an excavator for my first moc, i make an mlcad designed of the excavator first and then make instructions from that to help me but as i am building it i came a cross a few problems,it is a good idea to have a basic collection of Lego, to test and change things if you are going to do it on a computer

I am sorry you did not understand dluders wrote I know what Alasdair wants to do -- he wants to create some rock sieve trays to sort gravel ranging in size from 3 cm (1.18") to dust. This is called "inch and a quarter - minus" size gravel. The sieve trays are stacked on top of each other, with the largest sieve size on top. The smaller-sized rock grains fall down through the sieve to get captured on the appropriately-sized grid. The trick is to make a shaking tray that can vibrate a lot of weight to shake the gravel through the sieves. Recommend making grid sizes of 2-1/2 cm (roughly 1 inch), 1-1/2 cm (~0.6 inch), 1 cm (~0.4 inch), & 0.5 cm (~0.2 inch). Perhaps the oval-shaped #6575 Technic Cam (pictured below) could impart an up-and-down motion to a stack of sieve trays. thanks for the help i will look into your idea

I have got a good challange for you all how are interested i need a way of sorting stones into diferant piles here is a early atemped i did not like how i had to stop it when i had to emtey the big stone or add more stones to into it. In reel life they work by vibration to sort out stones look forward to the creation that people come up with it is not going to be easy there 3cm to dust stones to be sorted http://www.bricklink.com/store.asp?p=alasdairryan

I might be able to make some instructions for the steering if you want or ramps ,just give me a size.

Have you tried using beveled gears they are a bit bigger than the normal gears. http://www.bricklink...tem.asp?P=32270 http://www.bricklink...tem.asp?P=32269 http://www.bricklink...Item.asp?P=x403

Greetings. I would also like to figure out how to make some of the wheels self-steering. Hi, if you make the lorry pf functioned and you get your trailer pf functioned then you take an extension cable from the front left of truck to the back right of the trailer, and the right of lorry to the left of the trailer. Another way is to wire the truck and trailer separately this would make it with no cables between the truck and the trailer.

Here is some more images. http://www.mocpages.com/moc.php/144473 I am working on the pneumatics and wiring I still got to build the engine (pump).
