Giles Posted November 4, 2018 Author Share Posted November 4, 2018 Crane now works...... there's a couple of small details to add, but it's basically there. 7 Link to post Share on other sites More sharing options...
johnlostcreek Posted November 17, 2018 Share Posted November 17, 2018 (edited) Great work Giles. I love your work. No longer done model building for a long time. When I see your work, it gives me the spirit to pick up the model building again. Edited November 17, 2018 by johnlostcreek 1 Link to post Share on other sites More sharing options...
Giles Posted November 17, 2018 Author Share Posted November 17, 2018 John - you must - your models are absolutely superb..... much better built than mine! Get back to building!!!!!! 1 Link to post Share on other sites More sharing options...

Giles Posted December 20, 2018 Author Share Posted December 20, 2018 Next up is a Mechical Horse. Not the Scarab, but the earlier 3 Ton predecessor. I picked up a kit from Ebay a couple of years ago, made by SuperScale, just on the off-chance I could do somethinng with it, and I'm having a bash...... I haven't solved all the issues yet..... 2 Link to post Share on other sites More sharing options...
Giles Posted December 20, 2018 Author Share Posted December 20, 2018 2018-12-17_05-05-02 by giles favell, on Flickr Because the Mechanical horse is renowned (indeed designed!) for its manoevrability, the trailer has to be capable of spinning on its own axis. This means the trailer wheels need to be capable of turning in opposite directions - unlike all my previous vehicles, which have fixed axles. This I have done by splitting the axle, and sleeving it, which seems to work well. I also fitted simple tube bearings to the trailer, rather than rely on the small amount of white metal. The battery will go in the cut out, and a false floor laid over the top. 9 Link to post Share on other sites More sharing options...
Giles Posted December 20, 2018 Author Share Posted December 20, 2018 (edited) I'm using a smaller motor than usual on this one. It's only 6mm x 8mm in section, but still has lots of guts. Output is approx 90rpm at 3.7v. Gears are printed ones off Ebay. They are smaller than the ones I normally use (which is why I'm using them!). They are a little fussier to mesh, but made of an extremely hard plastic, and the smaller size is certainly beneficial. We'll see how they go..... 2018-12-18_04-52-34 by giles favell, on Flickr EDITED to correct motor size..... They're smaller!

Robin2 Posted December 20, 2018 Share Posted December 20, 2018 The battery will go in the cut out, and a false floor laid over the top. Fabulous as usual. But with the battery in the trailer you won't be able to uncouple the tractor ...R 1 Link to post Share on other sites More sharing options...
Giles Posted December 20, 2018 Author Share Posted December 20, 2018 Thank you Robin. No - but I'd rather have the two-day endurance!!!! 2 Link to post Share on other sites More sharing options...
Ruston Posted December 20, 2018 Share Posted December 20, 2018 Hi Giles. Did the motor come with the gearbox already fitted? Link to post Share on other sites More sharing options...
Giles Posted December 20, 2018 Author Share Posted December 20, 2018 (edited) Hi Dave, yes - the usual Ebay sources.... nominal 5v about 120rpm £3.60 ish.... It's got an odd bush on the end, but with care one can epoxy a gear on to it! Edited December 20, 2018 by Giles Link to post Share on other sites More sharing options...
Giles Posted December 20, 2018 Author Share Posted December 20, 2018 Just got the thing running under radio control...... nice (quite low) top speed - just what I was hoping/planning for, but LOVELY slow speed control! Much better than the larger motors I've used so far. Just about to buy a stock of these from Ebay..... 2 Link to post Share on other sites More sharing options...
Giles Posted December 21, 2018 Author Share Posted December 21, 2018 2018-12-21_09-10-06 by giles favell, on Flickr Well, electrics on the tractor are wired up, though not fixed, servo is in, font wheel fitted with its steering arm, and linked up, and it all works extremely well (apart from the servo operating 'backwards'). As I've said, the gearmotor performs even better than the larger ones I've used previously, with incredible slow speed control (I've just ordered another 4 from Ebay for stock....) The turning circle is lovely and tight, though slightly tighter in one direction than 'tother. It will all do very nicely. Got to finish it now though, which will take time, and I've bought a programmable transmitter which will allow me to reverse the servo control (arriving after Christmas) 10 Link to post Share on other sites More sharing options...

Greengiant Posted December 21, 2018 Share Posted December 21, 2018 When I read ‘Mechanical horse’ I thought he cannot be serious, Giles has lost the plot, then I read on and phew, it has wheels and not legs! Martin Link to post Share on other sites More sharing options...

Simond Posted December 22, 2018 Share Posted December 22, 2018 If I recall correctly, Narrow Gauge & Industrial Modelling Review carried an article in which a 2’ gauge wagon was pushed along by a chap in a coolie hat. The legs did the pushing by means of springs and cams. It was most convincing, as the feet sometimes slipped. Even with the advent of lipo batteries & Deltang receivers, I think the working 0 gauge shuntin’ ‘orse is a while away yet...

otherplanet Posted December 22, 2018 Share Posted December 22, 2018 Lovely work as usual Giles. Impressively quiet too, you can hear the dashboard clock ticking, or maybe that is the servo. Looks like the trailer reverses nicely. Are you going to paint it in Denton corporate colours, or will it be making deliveries to the mill? 1 Link to post Share on other sites More sharing options...
CME and Bottlewasher Posted December 22, 2018 Share Posted December 22, 2018 If I may interject Simon, my guess is that some sort of holographic tech will end up being cheap enough to have little folk walking around our layouts. Nano tech will also enable material bodied figures to move to a degree. I dare say, as its already happening to an extent, that Giles' industry will be the first to use such in 1:1 scale.... 2 Link to post Share on other sites More sharing options...
Giles Posted December 22, 2018 Author Share Posted December 22, 2018 I Asked Di - 'Red or green?' And she said 'green' so it will certainly be private owner, but I've not quite made up my mind whether it will be DENTON or someone else..... I should have hated to do it in 4mm!!! 2 Link to post Share on other sites More sharing options...
CME and Bottlewasher Posted December 22, 2018 Share Posted December 22, 2018 ......oh and Giles, you have captured the movement of Iron Horses/Scarabs really well. Superb as always. Are you still using the same make of batteries as you recommended to me? The season's greetings to all, CME Link to post Share on other sites More sharing options...
Warspite Posted December 22, 2018 Share Posted December 22, 2018 Giles Your RC work never ceases to amaze me. I've been trying to catch up on your thread and you just keep churning them out! Can't wait for the next project ... Stephen Link to post Share on other sites More sharing options...
Giles Posted December 22, 2018 Author Share Posted December 22, 2018 Nice surprise today, The new transmitter arrived much earlier than expected! It took a while to work out how to bind the receiver to it, as there are no instructions for this particular pairing, but I worked it out eventually. The servo is now nicely reversed and the steering is correct! I've located the receiver and packed the wiring away as best I can in the fo'c'sle, to leave the view clear.... (and I've checked it all still works...) 2018-12-22_04-09-48 by giles favell, on Flickr 7 Link to post Share on other sites More sharing options...
