  1. A better video: I've since painted the white elastic black, and made some sides for the flatbed, as the loads and battery kept falling off. I've also 3D printed my own gearbox housing, which I've fitted to the lorry as well. After some fettling, and a bit of oil, it works really well
  2. First full test of all driving and crane functions:
  3. HIAB ordered and fitted out with elastic and fishing line, and I found that the same thing was happening with the pivot point for the first moving section - ie the tension from the elastic combined with the tension from the fishing line on the other side tended to want to pull the joint apart. Its very much more substantial than the Palfinger construction, but still only a small hole in the upper section fitted over a small dimple on the lower section. In the end, I just cut this off and replaced it with a section of truck axle. Here's the first test: Pleased with this now. It only lifts its own weight, but another bit of elastic on the lower section should sort that
  4. First test of the arms of the crane. Only a partial success - the top bit works fine, but the bottom bit only went downwards and then broke at the pivot point shortly after I finished this video. I think I'm going to change and use the Hiab instead of the Palfinger. Both from Herpa, but the Hiab is more substantially built, without the silly black linkages passing over the back of the main body of the crane. Still, quite exciting to see it working for the first time. On to the mk2
  5. Some photos of the base of the crane - the cog has an 8mm hole in the centre, so I cut some 8mm diameter tube and mounted it to the chassis for the crane to pivot around. The motor to drive this will be mounted vertically in the back of the cab. Sensible size photos this time
  6. Went to a fishing shop to buy some fishing line, so I've been fitting the pulley system to the Palfinger crane. Eyesight test for sure! The line is 0.22mm diameter, and I used the smallest drill bit I had to drill a tiny hole in the 1.5mm diameter motor output shaft. With the motor fitted underneath the chassis, nd the fishing line wound around the output shaft, operating the motor will wind in the line and retract the crane. I'll use either tiny springs or elastic to pull it back out. Thats the theory anyway
  7. I added the vehicle lighting kit from Justin at Scale Model Scenery to my beavertail truck at the weekend. And of course it already had the flashing warning beacon, from the same supplier. Weirdly, I had to attach the resistors intended to allow 12V operation to both the white and red leds in order to get them both working from the one output, and I dont really understand why. When connecting all four leds in parallel (without resistors) - only the two red leds would come on. Admittedly, electronics is not my strong point. I can handle a bit of soldering, but thats about it.
  8. So i finally got hold of one of the new Train Tech Smart Screens, and I've made a weighbridge! So now the trucks can be weighed before and after depositing their load in the ballast bins. The video was shot before I'd finished the weighbridge itself, just to demonstrate the display, which is a remarkable little thing: To model the actual weighbridge itself, I just painted a red rectangle on the ground, and outlined it with a concrete colour. Add an ANPR camera and a handrail, job done. Marvellous
  9. Here's a quick test of the low loader in action:
  10. Very useful, thanks Last night I finished the low loader trailer (which originally came with the Eddie Stobart Volvo FH cab), which plugs into the same port as detailed above. Really easy to do in all honesty - 10 minutes with the Dremel and it was ready to go. Hardest part was pulling the original pins out of the ramps. The ramps are glued to 3mm dia tube, glued to 2mm dia tube which pivots in the 2mm dia holes in the end of the trailer. In truth I could have just glued the ramps direct to the 2mm dia tube, but there would have been a bit of a bump to get onto the deck. A G700 motor is mounted underneath the deck, turning the ramps via an S15 worm and a Z19 cog. This is the same basic mechanism as operates the ramps on my beavertail truck. Route the wires and solder on a 2 pin connector. Just needs a bit of green paint to hide the brass now. Photo sequence below:
  11. I've upgraded my tipper cab with the facility to attach different trailers, via a tiny 2-pin connector which conveys the pair of wires to the second motor. On the tipper, this is the motor that tips the trailer up and down, but it also means I can connect other trailers with moving parts to the same cab unit without building up a tractor unit for each trailer. Next on the list is a low-loader with raising and lowering ramps.
  12. It was that video that made me want to do mine He has 3 G700 motors for the crane (one of which I think was planned to extend/contract the boom but isnt used because that would be too many motors for a single receiver) which are lined up under the bed pulling fishing wire through the rams, plus one vertically in the back of the cab which turns a cog to rotate the crane. As above, tiny springs push the crane arms apart. I'm going to try elastic around the back of the arms first, as I dont know where to get such tiny springs from at the moment. Herpa do a Palfinger and a Hiab, the one in the video is the Palfinger. I've seen both and I think the Palfinger is the more suitable of the two, and its also cheaper (although they come in a pack of two, so more expensive overall but cheaper per unit)
  13. Here's the finished truck being tested. I think the battery is disguised well enough:
  14. Working on an Eddie Stobart Volvo FH lorry cab at the weekend, with a couple of new battery sizes. The cabs seem to be just the wrong size to fit any battery inside, so I resorted to cutting the back off the cab and sticking the battery in its place. I'll paint this white and stick the air intake back on and it'll look passable for a part of the lorry that will be at least partly hidden. I'm going to upgrade both of my other lorry cabs with a proper servo like in this one. Linear servos are fine for the smaller vehicles, but I find they cant handle the weight bearing on the front wheels when used on a lorry.
