Switcher102 Posted July 5, 2013 Share Posted July 5, 2013 Excellent Giles, it's looking good. The material you've used for the cable reacts well. It's not too stiff and hangs very much like the real thing, and the crane trolly (whatever it's called) moves well. I look forward to the progress of this project.

johnlostcreek Posted July 25, 2013 Share Posted July 25, 2013 (edited) Hi Giles, Small progress in the process create flanges for the wheels on the lathe 31 by johnlostcreek, on Flickr 33 by johnlostcreek, on Flickr wheels and servo mounted 37 by johnlostcreek, on Flickr Have to connect the servo to the steering rod 36 by johnlostcreek, on Flickr for the photo with the cab and the loading box mounted 39 by johnlostcreek, on Flickr now start connecting: serfo receiver, motor and battery then I hope driving the car But all new for me is there a plan to connect the wires.

Giles Posted July 26, 2013 Author Share Posted July 26, 2013 John, that's beautiful! I've seny you an email with a wiring diagram - let me know if it doesn't arrive..... Link to post Share on other sites More sharing options...

Giles Posted July 28, 2013 Author Share Posted July 28, 2013 (edited) The crane is basically finished, but I will now have to build a pair of powered sliding doors to sit behind the arch to 'reveal' the load ready to traverse out. A view of the 'Zero Fleet winches' which keep the wire rope aligned at all times..... simple really! Edited July 28, 2013 by Giles 3 Link to post Share on other sites More sharing options...

johnlostcreek Posted July 28, 2013 Share Posted July 28, 2013 (edited) Hi Giles, Beautiful, Nice solution with the bolts as drive for the cables One more question. How to load the 3 .7V lipo ? John Edited July 28, 2013 by johnlostcreek Link to post Share on other sites More sharing options...
Giles Posted July 29, 2013 Author Share Posted July 29, 2013 (edited) Hi John, If you mean 'charging' the Lipo, I used a 2.5mm mono audio jack plug, with a socket mounted in the cab floor - you can just make it out directly to the rear of the servo The advantage of this, is is you wire it according to the diagram (it is indicated as the horizontal black bars) when you plug the jack in, it disconnects power from the receiver, regardless of the position of the on/off switch. However, there are lots of different plugs ou there to use - many smaller! Mounting the Lipo itself, I simply used some epoxy resin, as I could easily cut it away and replace it it necessary. Hope this helps! Edited July 29, 2013 by Giles Link to post Share on other sites More sharing options...
Giles Posted July 29, 2013 Author Share Posted July 29, 2013 Amazing great work Giles. Thank you Barnabŷ! It'll make operation more fun....... But the winches do work very well. Link to post Share on other sites More sharing options...
Pete Harvey Posted July 29, 2013 Share Posted July 29, 2013 Giles Do the motors move across as the bolts wind through the nuts? Pete Link to post Share on other sites More sharing options...
Giles Posted July 29, 2013 Author Share Posted July 29, 2013 Hi Pete, yes - they do indeed. The motor/bolt assembly winds itself across at the same time as paying out or winding in the cable. The cable therefore always stays perpendicular to the drum, thereby making it a 'zero-fleet' winch, as opposed to a winch where the cable will naturally travel sideways as it winds on.

Giles Posted July 29, 2013 Author Share Posted July 29, 2013 Hi Giles, Thanks What charger do you use John I actually bought a Uniross charger from ebay but thre's quite a lot of choice - so long as you don't over-charge them Link to post Share on other sites More sharing options...
Giles Posted July 29, 2013 Author Share Posted July 29, 2013 GilesVery nice what limits the motor travel in either direction?Pete I did buy micro switches (to mount at the end of the 'bolt' so it would cut out on over-travel) but it travels so slowly, and there is excess travel available anyway, that I didn't bother fitting cut-outs in the end..... The motors are 12v, running on 1.5v andgiving me a lovely slow scale speed, and the switches are 'momentary' sprung to centre off, so there's not much danger in practice Link to post Share on other sites More sharing options...
johnlostcreek Posted July 30, 2013 Share Posted July 30, 2013 (edited) Hi Giles, am very interested in a photo of the right side of the engines (from the Zero fleet lieren) John Edited July 30, 2013 by johnlostcreek Link to post Share on other sites More sharing options...
Giles Posted July 30, 2013 Author Share Posted July 30, 2013 I don't know if this is any help, John...... The 'bolts' are drilled 3mm down the end to accept the motor shaft, which is then fixed in with milliput epoxy putty. To prevent the motors rotating, there is a 'U' bracket of brass strip glued to the motor body which goes over the top of the motor, and over the face of the support bracket (on the other side), allowing the motor to travel sideways, but preventing rotation. Much simpler to do than to describe.... Link to post Share on other sites More sharing options...

Giles Posted July 31, 2013 Author Share Posted July 31, 2013 Very nice John! It makes for a very neat install. What is the overall gear reduction? (Motor/gearbox + 38 : 1 final drive) Link to post Share on other sites More sharing options...
johnlostcreek Posted July 31, 2013 Share Posted July 31, 2013 I don't know yet. I will test it, When the gearbox is built in. I have 3 engines with different speeds Link to post Share on other sites More sharing options...
