hi guys this is the instructions for my knex bulldozer hope you like it and please comment.also some credit to imperer for the steering he made for front wheels.i changed it quite abit to make it  rear wheel steering and also added a mechanism to it but his steering did help me a little so thanks to him.

This instructable is is about 63cm long which is just over 2ft .the widest point is about 28 cm which is just under 1ft. the highest point is about 25cm high which is not that far under 1ft either.
this is just to give you an idea of how big is is before you decide to make it or not.

one of the best feautures on it is that i made a handbrake system going from the back to the front on a hindge which is pretty cool.also the back opens up and obviously the scoop goes up and down and pivots also.  

Step 1: Back Part,steering and Handbrake

Step 2: Front Part,handbrake and Scoop

    Im sorry but i cant build it because of my competition. The pick-up-truck im building for it uses about 1000 pieces and i have 2 cars up allready . I am not prepared to dismantle them yet because i need more edditions of both.By the way, i am still going to build it and Sure I will send pics of it butt i am going to a car boot sale on sunday and maybe if i get some knex there , Ill start your bulldozer. In addition, If i build it , can I post it as an instructable on my profile but I will mention you if that is ok. A short question, " how many models do you have built now (fully built) and are you planning on any new ones for the future.

    Happy building , KD2

    Sure . Ill mention you and good luck on your coach. I know steering can be difficult but determination will get you there. I need a lot of it because im making my own knex ball machine in the form of a roller coaster. Does'nt really work. Well anyway , good luck.
