VKTechnic Posted August 12, 2014 Author Posted August 12, 2014 Wouldn't it be better to use one 12 tooth gear with a half bush on each side to make it inline with the 20 tooth gear? No, because the 12t gears move horizontally. If I used just one 12t gear, the transmission would disengage in one of the gears. Quote
Black-Build Posted August 12, 2014 Posted August 12, 2014 (edited) I think you'll need to redisign your gearbox a third time... Edited August 12, 2014 by Black-Build Quote
VKTechnic Posted August 12, 2014 Author Posted August 12, 2014 I think you'll need to redisign your gearbox a third time... That's most likely the case. Quote
Black-Build Posted August 12, 2014 Posted August 12, 2014 I just tested your current and I also tested it with instead of three 12 teeth gears, two and on each side a half bush gear. It still slips but way more force is required to make it slip, and I'm not sure if two Xl's have this power... You might give it a try. Quote
Technyk32231 Posted August 13, 2014 Posted August 13, 2014 It's the simplest way to add negative caster to the front axle. You mean positive caster. Quote
VKTechnic Posted August 13, 2014 Author Posted August 13, 2014 Finally got a working gearbox! Now it's time for the fun mechanisms You mean positive caster. Yes, you are correct Quote
VKTechnic Posted August 14, 2014 Author Posted August 14, 2014 I've been working on the 6x6, mainly strengthening the rear chassis (nothing too interesting). However, I want your opinion: what should the rear end be? Here are a few of my choices: 1) The original idea, a tow truck rescue arm 2) A tilting tow bed, also extendable. 3) Military missile launcher 4) Standard rear cargo bed Which one do you like best? (Or is there a better one that I left off the list?) Quote
VKTechnic Posted August 15, 2014 Author Posted August 15, 2014 After combining votes from my Facebook page, Flickr, and Eurobricks (oh, and my own vote, of course), the Rescue Arm is the final build. I've started working on the "deck" around it, and as you can tell, it's much too high. This calls for a chassis redesign... >.< Quote
VKTechnic Posted August 25, 2014 Author Posted August 25, 2014 Finally a build update! The rear end is basically done, just a few minor details left. I rebuilt the rear chassis entirely, lowered the rear bed, added a rear bumper (with lights!), and installed the towing arm. I've also been doing occasional test drives, and it drives wonderfullly. Steering could use a little reinforcement though... Quote
Zerobricks Posted August 26, 2014 Posted August 26, 2014 Now thats gonna be one awesome tow truck! Quote
HorcikDesigns Posted August 26, 2014 Posted August 26, 2014 Looking forward to see it finished, but I would maybe remove the upper LA, because of simpicity ;) Quote
Black-Build Posted August 26, 2014 Posted August 26, 2014 (edited) I think you should build ''the deck'' in black... But grey doesnt look bad either Is the crane remote controlled? Edited August 26, 2014 by Black-Build Quote
VKTechnic Posted August 27, 2014 Author Posted August 27, 2014 is there last axle has stiring ? Yes, the rear axle is steered. Is the crane remote controlled? Nope, both LA's are manually controlled. The winch, however, is motorized. Quote
VKTechnic Posted August 31, 2014 Author Posted August 31, 2014 Progress is slow, but it's there. Only a few days left until school starts again, and a little over a month until BrickCon (and I still have to make a model for that). Meanwhile, the cab is coming along nicely. There won't be an interior because of the gearbox and electronics (5 motors, 2 switches, 2 receivers, and 2 gearboxes, plus 3 pairs of lights). However, all four doors open, and so does the hood. Also, you can see the maximum steering lock in this picture. Quote
piterx Posted September 1, 2014 Posted September 1, 2014 i usually don't like trucks but i have to say this one is really cool :) i love the steering system, just like on the real RC models Quote
Talles Posted September 1, 2014 Posted September 1, 2014 (edited) What tire is this? what are the dimensions? Edited September 1, 2014 by Talles Quote
VKTechnic Posted September 1, 2014 Author Posted September 1, 2014 (edited) What tire is this? what are the dimensions? The tires are Axial Ripsaw 1.9 tires. 109mm outer diameter. These tires are so sticky that I often find LEGO bricks stuck to them when I move the model from my desk. Edited September 1, 2014 by Victor Kojenov (TFOL) Quote
Zerobricks Posted September 1, 2014 Posted September 1, 2014 Thats one foxy looking truck! Nice detail with rear axle steering, though I think the truck would work just fine without it. You know whats next? VIDEO of the foxy beast! Quote
Boulderer Posted September 1, 2014 Posted September 1, 2014 Great looking truck. Another case for TLG partnering with specialist tyre manufacturers Quote
