    Looking great. I love the way you've got the bonnet to spread out as you move from the front to the back. Really nice. And love the suspension components...real low-rider.
  2. SteveNesta
    It does indeed look very cool. It looks like it can take some serious weight also....like a tank ;-)

    Outstanding ! Some really interesting details. I love the exhaust tubing, the steering wheel, the carbs, and even the rain light. Spot on with the ’70s look. Add a racing number in a circle :-)

    Cheers :-) I'll make another video in due course with a tank mounted camera. And assuming the reloading goes smoothly, I'll unload the whole magazine and also drive over a few things to show the suspension. It is under a fair bit of strain, already pretty twisted due to the weight. Also the 4 XL motors on channel 1 receiver are causing a few issues with cutting out. I'll see about ensuring its a V2 receiver. Been taking a little lego time off, to make sure my Lego-widow gets some much needed attention ;-) Next MOC is then trailer to transport it. Just working up my ideas around what power functions and mechanisms that will have. So far I'm buying all the lights and dark grey stuff on eBay lol.

    That is where I took my online name from, yes :-) Hehe he was a freebie with a Lego order. So it was either going to be him driving the tank, or getting killed by it. I took the easy option.

    Two XL motors turning a cam pushing back against 2 springs from the Unimog suspension :-). If you have a look at my other thread with the build pictures and video, you'll get a better idea how it works. I've modified it since my build videos to increase the motor power and change the gearing. It's now very reliable and very powerful. :-)

    Here are a couple of videos....hope they are up to the forum's standards... Videos: In action - Iron Man gets shot. --- The functions.

    Cheers......I'm very pleased with it....looking forwards to the final few bits from eBay. Here are some hi-res images. Will make a YouTube vid very soon. 200 - The barrel support brace is in the up position ready for driving. ------ 201 ------ 185 - The torsion beam suspension is under a lot of strain ------ 186 - Side profile with rear bucket in extended position, and turret support brace retracted, allowing the turret to rotate ------ 187 - Maximum elevation approximately 25 degrees ------ 188 - Turret down and stowed, ready for driving ------ 189 ------ 190 - Rear bucket deployed, turret elevated, ready to fire. ------ 191 - with the barrel support brace in the elevated position, the driving lights are visible (there will be 8 in total in this opening), and covered over when in shooting mode, ie, brace retracted and rear bucket deployed. ------ 192 - Comms tower at the rear...basically all the little bits and bobs I could find and stick together....just a bit of fun really. Smoke generators (non functional !) on the top surface at the front. ------ 193 - Functioning chain driven machine gun next to the turret (with the yellow ring at the end) ------ 194 - 4 yellow flashing hazard lights (flashing in pairs) when the support brace is extending or retracting. This is tied to the rear bucket, which also has 2 pairs of flashing warning lights when moving. ------ 195 - Aerials, tubes and other fixtures ------ 196 ------ 197 - Barrel support brace tucks away completely. This was a real headache lol. Battery box blacked out to keep in tune with the tank. ------ 198 - Barrel support brace extended. ------ 199 - More umbilical cords and hoses. ------

    Finally finished it, save for a few more smooth tiles coming from eBay. A couple of low quality pictures, while I take some decent images and make a short video. Stats: Length: 71 studs - Body only, excluding rear bucket Width: 36 studs Height: 23 studs – excluding munitions reloader Barrel length: 54 studs Elevation: -5 degrees +25 degrees Weight: 4.760 Kg 13 PF motors 3 switches 8 pairs PF lights 2 Battery boxes 183 181 182 184 179 Videos: In action - Iron Man gets shot. --- The functions.

    And do look at how keyhole surgery cameras are moved within the body....it might give other ideas. Really interesting model....watching with fascination.
  11. SteveNesta
    So you are making a fake gun, but want a good recoil action? How about the action that I used on the machine gun, but with very low gearing and a pressure cylinder to damp the motion?
  12. SteveNesta
    Where did you get the idea for the movement technique? Keyhole surgery camera ?
  13. SteveNesta
    Wow. Really beautiful. Love it!
  14. SteveNesta
    Interesting. What's going to be fired? What kind of power are you looking for? I can't really figure out the annotations? Watching with interest. :-)
  15. SteveNesta
    Excellent news. Set thread to follow :-)
  16. SteveNesta
    See my tank thread and look at the flashing lights mechanism for the rear end using a PF switch and an M motor. If you use the gear on the motor to turn two switches set at 180 degrees apart, that should fit your needs.
  17. SteveNesta
    Thanks for the kind words :-) Here's a picture of a tracked self propelled gun with a 'bucket' at the rear...the rubber lift arms just provide a great level of grip. It's certainly pretty big, at 67 studs in length without the bucket and 24 studs wide body-only. 1.98Kg without battery packs....so far. The torsion beam suspension is a good use of Lego in my opinion, and the axles don't seem to suffer lasting damage when inspected. I've just swapped them around from left to right, so that they are now being twisted in the opposite direction. I've also added 2 further sets of road wheels, reducing the weight/strain per axle and it now sits much better with significantly less twisting. I'm looking at potentially adding a spring on the rear end road wheels to further reduce axle twist. I'd love to use a mini LA to change the ride height, but I think I've enough headaches for the moment :-) The gun is cool....I've just increased it's power again by moving the springs 1 stud forward so that compression starts earlier and is held longer before release. I'll see if it works and whether the motor can turn it. I hate the top mounted reloader, but it does the job at the moment. I'm going to find a way somehow to find a mechanism to load from underneath to keep the model looking relatively sleek. I'd love it if I can get that to work. Back to the bricks now ;-)

    Update. A few changes. - Modified the turntable mechanism, made it smaller. - Added the black cowling around the gun barrel. - Changed the tip of the gun barrel. Looks more aggressive now. - Added the panels to the very front of the tank. Next up - build the topside body work, and see what else can be added. Thinking about a holder for the front end of the barrel, and a retractable small comms tower. 134 - Underside using the elastic band to make the lower part of the bucket retract. Note: Red cowling now replaced in black thanks to Bricklink. 135 - Close up. 136 - Overhead of the bucket mechanism and large LA's 137 - Front end now with panels. 138 - Revised gun barrel with cowling and new front end. 139 - Simplified and smaller turntable mechanism. 140 - full size tank :-) 141 - All the motors in the rear has a rather detrimental effect on ground clearance :-( 142 - Torsion beam suspension is under strain. 143 - Rear stabiliser. The movement and grip from the rubber tips are enough to lift and move the entire tank. 144 - The other side. 145 - General 146 147 - Rear bucket extending 148 - Bucket extended. 149 - Bucket retracted.

    Love it, and love the use of the LA's. I was thinking of doing the same with my tank, but got sidetracked. Really looking forward to see more :-)

    Slight update...fitted some cowling around the gun barrel, just waiting for black parts to arrive on Bricklink then I'll photograph and upload....looks pretty good. I've fitted two large linear actuators at the rear of the tank, which I now think will be a self propelled gun. They will move a ground attachment to dig into the ground and manage the recoil effect of the gun (in real life that is). However, I need your help....I am trying to find a mechanism that will push back straight, and then downwards at an angle, as though it were extending and then digging in. Have a look at the photos and the videos to see the fixings. There is also a rotating axle underneath along the centre line, connected to the actuators, that can be used to turn something else, such as a mini LA or some other thing. When this mechanism is operating, a set of lights will flash - huge thanks to those who showed me the uses of the PF switch and how to make a small mechanism to make lights flash :-) 130 Mechanism for the lights 131 Mechanism for the lights http://thumbsnap.com/s/67QVKt2B.jpg 132 Underside showing the power going left, right to large linear actuators and straight down to a spare axle. 133 As above Videos: Linear Actuators Flashing lights

    Fantastic help with the photos. It's beginning to make sense now. Slowly lol. Thank you so much :-) Edited to add I have one servo motor at present. So ideas for uses would be great :)
  22. SteveNesta
    So how would I install it into the MOC to be able to make use of it remotely? I understand how I can do things by moving the switch by hand, but I don't understand why and how I would get a motor or mechanism to move the switch. 1. Regulating a pneumatic pump. - I think I understand why, but how would this work? 2. Opposite motor direction where multiple motors share the same power line. I get this, but that is just a 'change once' and leave it alone function. 3. Flashing lights I get this, but not sure how to implement it. Would you be able to share the why's and how's? Any other useful uses for this little device? Thanks :-)

    Along with all the motors and lights and IR units and controllers recently purchased, I also have a PF switch. As some of you have read, my current (and first ever) MOC is a large tank with as many functions as I can think of. I'm struggling to find a use for the Switch. Can anyone give examples of where they have built or seen the PF switch out to good use and where I might find a use in a tank and its various mechanisms? Cheers. :-)
  24. SteveNesta
    Cheers all. :) Here's the video of the ammunition conveyor belt prototype.....really ugly and cumbersome....and never to be seen again lol.

    Update...following some good advice above, I've changed the barrel elevation mechanism, which I loved for it's complexity and coolness going through the turntable, for an extremely simple mechanism. A motor attached directly to a single linear actuator. As you can see from the video, it goes up and down very quickly now. The downside is that the motor is located within the turret structure rather than the main chassis, which adds weight to the motor and I'll have to connect it to a battery point on the turret. Hey ho...no big deal. Disappointed a little by its simplicity lol. 129 - Barrel elevation mechanism Mk.3
