    Here's my newest model. I will be building this one first as soon as possible, but that depends on the delivery of a few sbricks ;) It's modelled around an NRC Industries Kenworth T800 Parts Count: 4350 Features: - Drive - Steer - Pusher Axle lift / lower - Outriggers extend / retract - Outriggers lift / lower (pneumatic) - Underlift deploy / retract (pneumatic) - Rotate - Boom lift / lower - Boom extend / retract - Winch 1 - Winch 2 Tag axle and underlift is detachable, so you can use the underlift with or without the tag axle (See final picture)

    I've used mouse trap springs before to create torque. It lessens the load of the actuators, but requires a very strong superstructure. If your boom weighs 2.3kg, you already have a very strong superstructure and frame.

    It will be pretty much impossible to fit pneumatics into that model team set. You should take a look at how set 8297 accommodates for adjustable suspension! Also, I laughed out loud about your experience with derogatory and offensive remarks from a certain someone, because thats apparently normal =/

    Thanks everyone for the positivity. Looks like I will be building the moving truck first from the oddly surprising reaction its gotten! Also it will be the cheapest due to lack of PF and such. just trying to finalize the lift gate design. Its pretty close to 100% real looks and real functionality!

    Thanks everyone! Its looking like the oshkosh TFFT will be first to build, as I already have a tremendous amount of parts for it. Also here's a picture of one of our 4 trucks in service at Firemen Movers

    Hey there. I figured I'd start a new topic to document my current LEGO projects. For the time being this will all be LDD designs I've created, as I wait for some extra cash to spend on bricklink. 1. Scania Rotator Tow Truck Parts Count: 4400 Progress: 90% Complete Features: - Drive (RC) - Steer (RC) - Air Compressor (RC) - Outriggers deploy in/out (pneumatic RC) - Outriggers lift up/down (Pneumatic RC) - Towbar deploy in/out (pneumatic RC) - Towbar lift up/down (Pneumatic RC) - Boom rotate (RC) - Boom lift (RC) - Boom Extend - Winch 1 (RC) - Winch 2 (RC) - Battery Set switch (RC) You'll notice this truck has more than 8 functions. In total it has 7 PF IR Receivers. First IR Receiver controls the battery back switch, which is a PF Medium motor and two polarity switches that will turn on either battery back 2 (with 3 receivers) or battery pack 3 (With the other 3 receivers) This way I can split the functionality of the truck into two sets: - Drive - Steer - Towbar - Outriggers and - Boom lift - Boom rotate - Boom extend - Winch 1 - Winch 2 You'll notice I also took a lot of inspiration for the design of the cab from Efferman's doctor brick community project of the scania flat bed. 2. Firemen Movers Freightliner Moving Truck - I work for them, its a Toronto-based moving company owned and operated by firefighters Parts Count: 3200 Progress: 65% Complete Features: - Drive - Steer - Custom stickers - Pneumatic Powered tail gate (incomplete, working on the trigonometry of it) - Removable top with fully designed interior, including equipment 3. OshKosh Tactical Firefighting Truck Parts Count: 5800 Progress: 95% Complete Features: - 8x8x8 (8 Driven wheels, 8 Steered wheels) - Independent suspension - Bumper Nozzle rotate and elevation - Roof Nozzle rotate and elevation - Water tank - Water pump - 3rd Party Tires

    The bent liftarms for the wheel arches will add a nice "fender flare" which would be appropriate for the size of the tires required for the 9398. If you are able to offset them by half a stud so they don't stick out from the body of the car by a full stud then that would be optimal. I don't have any familiarity with the crawler set otherwise I'd try my hand at integrating your design with it.

    Hey there, I'm not very familiar with best practices for creating 1 stud thick car/truck doors. I'm wondering if anyone has some nifty solutions (double hinged doors ??) for this problem, as I just can't figure it out....
  9. fasterthanlight
    two ports is absolutely necessary for an airtank ... input and output ... But effe - most fuel tanks aren't as round... the ends look a lot like ( ) Not so much like a pressurized vessel

    Thanks!

    Hey there, I've got a question about the pole reverser, as I do not own any myself and haven't been able to find this info anywhere online... 1. I assume there is an "off" position (Center?) Yes? No? 2. Does it require 45º of rotation to operate the switch using an axle through the middle?
  12. fasterthanlight
    $25 for 2 I had to buy 10, as the model requires a spare tire http://www.amazon.com/gp/product/B004M83P0S/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

    Tires arrived in the mail today... These things are MASSIVE

    I've figured it all out! I've rebuilt the entire nozzle elevation/rotation mechanisms I've built a nice gear box system that will tie in (through linkages) with the water pressure switch. The switch already has a mechanism that protrudes the two 5L orange liftarms from the side of the truck when you select which output you want. The longer 9L orange liftarm will be part of the linkage system that will tie in with the orange 20T bevel gear in the second picture. This way, when you choose which nozzle the water will pump through, it automagically selects the proper nozzle to rotate and elevate with the M motors Whee!!
  15. fasterthanlight
    Thanks I've hit a bit of a road block ... I'm going to have to re-think how I manage the nozzle elevation, as when I was spec'ing out this beast I treated the drive functions as "one output" on the receiver. I now realize that I will have to split up the 4 L motors across two outputs. Which leaves me one function short ... I think I will have to make the elevation of the nozzles for both bumper and roof mounts to be controlled by one motor... Functions will be as follows Battery Pack 1 1 - Drive (x2 L-motors) front axles 2 - Drive (x2 L-motors) rear axles 3 - Steer (x2 Servos) 4 - Water pump pressure (1 RC Buggy motor) ------ Battery Pack 2 5 - Nozzle selection (1 M motor with pneumatic valve to switch water pressure from bumper nozzle to roof nozzle) 6 - Bumper nozzle rotation (1 M motor) 7 - Roof nozzle rotation (1 M motor) 8 - Bumper & Roof nozzle elevation (1 M motor, with possible manual gearbox selection to bring back independent nozzle elevation) And now as I write this I realize there might be a mechanism I can whip up that will tie into the water valve control that will also switch which nozzle is currently being operated

    4500 parts so far -- over 1000 just in pins Width is 25 studs Length is 109 studs (so far) Probably close to 6000 parts when all is said and done I'm hoping the weight isn't an issue for the third party tires I'm using... We'll just have to see... =/ I'm not too concerned about that, there is plenty of room around the tires as it is, and when its actually built, the shocks will push the suspension arms down about half a stud more than they do currently. There won't be too much suspension travel to begin with, this is just an industrial sized off roading vehicle, not a rock climbing device. The real truck is geared to dirt roads (limited access roads etc) and being able to climb steep hills when it needs to
  17. fasterthanlight
    Yea I'll probably do that in real life when building it... Almost done the cab, lots of tricky angles to work with ...
  18. fasterthanlight
    Thanks everyone. It certainly is going to be a beast, and an expensive one too.. however I have a huge stockpile of DBG liftarms and parts already. The front of the truck is taking me forever to model. I had to switch around the front two axles because the L motors would stick out strangely in the front of the truck Built the two monitors, both with rotation and elevation control. Trying to tie it all together now
  19. fasterthanlight
    - A lot of body work done. - Doubled up on the shocks due to potential weight concerns - Re-located their mounting position to the top of the suspension arms, as to have them on the bottom ones runs the risk of them popping out of the ball joints of the hubs - Water tank roughed in, with openable hatch on the top - Ground ladders added - SCBA bottles are now yellow with a green stripe, just to add some colour to this grey beast Parts Count so far: 3368
  20. fasterthanlight
    ya its inconsequential that they don't have the gaps. an 11L liftarm is still an 11L liftarm..... It cleans up the visual distraction of the instructions and makes it easier to follow along..
  21. fasterthanlight
    Thanks everyone. Worked on the crew cab, includes opening doors, opening roof hatch, seats with SCBA bottles mounted in them. Working arm rests too...

    Update: - Double servo, and steering system updated - Water pump updated, no longer dependant on 40t gears. Also reinforced - Some minor body work - Lots of small tweaks and fixes throughout Don't worry, I won't spam the forum with minor updates, I'm just bored right now and procrastinating on my studies
  23. fasterthanlight
    Will consider double servo, I don't own one yet so I have no idea what its capable of. Plenty of room in the central lower half of the frame to build out different options in real life if that is the case. Axle modules are the same, but steering ratio for each differs appropriately. ---------- re: the water pump, I'm using 40t gears so that I can offset each set of two pumps by 90º (didnt bother wasting my time in LDD to draw that aspect out, not important) so that at any give time there is always one set of pumps pushing air, that way torque is low because its only two pumps really pushing, and hopefully that keeps the RC rpm's up enough to actually create some decent pressure into the water tank. Will share it once I make some more progress :)

    Hey there, been browsing this forum for a lonnnnnnng time now - - posting every now and then Thought I'd give LDD a try, normally I freestyle build everything, and there are two large fire/rescue projects I've been working on a for a long time now (Which I won't post until they are done) But I don't mind sharing my progress with the stuff I'm trying out in LDD As such, here is an Oshkosh 8x8(x8) Tactical Fire Fighting Truck (IN PROGRESS!) The real truck doesn't have 8 wheel steering, however I decided to keep all the axle modules the same, and it will be that much more awesome The 15L crossed black lift arms on the wheels are a moc up of the size of the third party tires I'm going to put on this beast. It will have a water pump, bumper nozzle, roof nozzle, all remotely controlled 1L Motor for each axle (4 total, on one V2 receiver with dedicated battery pack) Servo for steering RC Buggy motor for water pump (x8 pumps) 1M motor for each nozzle rotation 1M for each nozzle elevation (Nozzle operation might be done with a fancy gear box to reduce amount of motors) Additional batter pack for steering, water pump and nozzles
  25. fasterthanlight
    Looking good so far! But I think its a few studs too wide for the size of the tires :( The headlights on the real car are right to the edge on either side of the car, but its looking like the tires are sticking out too far
