  1. Inspired by the release of the planetary hubs and the diff lock idea from Zetors I decided to create a proper, realistic Tatra 8x8 with the following goals: Use of planetary hubs - Keeping it realistic, so no portal ones No load bearing axles - Most other models used the same drive axle to also hold the half-axles in place which increased friction in the driveline Realistic steering setup - Using a smillar mechanism the real trucks use Differential locks on all wheels - Each axle has it's own diff lock + a central one Here's what I came up with so far... The concept uses the blue bevel gears to transfer the power to the half-axles without spinning the pivot axle. This also allows for wheels to turn at different speeds when cornering. Once the power is transfered to the half-axles an additional gearing is used before the power is delivered to the wheel. Total gearing on half-axles alone is 1:9. Differential locks work by locking one of the differential's output to the main drive axle. As mentioned before all 4 axles have lockable differentials along with the central differential. Steering uses a couple of 9L links turned by the turntable acruated by an 8 tooth gear. This setup provides the front axles with slightly different steering angles. The model will probably powered with 4 of the BuWizz motors. Total gear ratio is 1:21 which should give the model around 900-1000 Ncm torque. I think the concept looks very promising so far and I will keep on building it virtually until I'm confident enough to order parts.
  2. Hi there, While building a small rc car using a RIM 55982 (18 x 14) I needed a way to lock the wheels to be able to drive it with a motor. Almost started drilling holes ..... and then, after removing the tire, it turned out there is a little notch inside the wheel. Looks like it is a space for a tiny piece of plastic to slide in, to lock the axle to the wheel. Exactly what I'm looking for! Have I missed something? Is there a LEGO part that fits this notch and locks the wheel? Or should I make it myself.
  3. I have been thinking of putting my safes on Eurobricks for quite a while, and I've finally got around to doing it, thanks to the interest from @Leonard Goldstein. So, starting with the smallest... 1. Micro Combination safe Size: 4 x 6 x 6 1/3 studs. Instructions: No. Digital Model: Yes, for LDD. Video: Yes, see below. Photos: Video: 2. Mini Lock with key Size: 6 x 6 x 2 2/3 studs (not including shackle). Instructions: Yes, available on Rebrickable. Digital Model: Yes, for LDD, LDraw, and Video: Yes, see below. Photos: Video: 3. Mini Combination safe Size: 6 x 8 x 7 2/3 studs. Instructions: Yes, available on Rebrickable. Digital Model: Yes, for LDraw. Video: Yes, see below. Photos: Video: 4. Big Combination safe Size: 8 x 16 x 9 2/3 studs. Instructions: No. Digital Model: Yes, for LDD. Video: No Photos: That's all I've got for now, though I do plan to make some more (bigger/better) safes and (better) locks in the future...
  4. Hello everyone, I have many old sets which are using this differential and as you can see, you can easily create differential lock using part But I was wondering - is there any official set which actually uses this parts combination?
