Invicta280 - yes i was very pleased with the way the gearing turned out and how the engine rpm fluctuations dont seem to effect the locos speed to much....it was a bit of trial and error to be honest and luck played a big part but it seems to work pretty well.

I now want to attach as many cars/carriages to shunt as possible and see how much he can actually pull.....it may mean revving the guts out of the engine but i want to see what i could actually pull

Does anyone on here know what a good size load is? how many carriages are classed as 'alot'?

I am still eagerly looking for places to run this loco and any takers would be much appreciated

I'm impressed Anton. So am I right in thinking this loco has no esc, it's simply powered straight from the generator? Also, on your warship, is the silencer a proprietary item or one you've made?

I'm building myself a live diesel so I'm keen to see how you've done it. I was thinking I'd need an ESC but I guess it depends on the generator output. What is the motor/generator?

midwalesstokie:

Thank you. You are right in thinking 'Shunt' has no ESC, but instead of a speed controller it has a voltage regulator. You are correct in saying that theoretically you could just have the generator linked directly to the traction motor (letting RPM govern forward speed) but as i have no clutch fitted, the generator is always making current, and as its fairly big, well big enough to be used as a starter motor as well, the minute the nitro starts, the loco would jolt forwards.

Have a look at this video of how fast it was when it was just direct drive from geni to traction: http://www.youtube.com/watch?v=3DzOyErdUhw

Now on the warship i am using an ESC. Moreover the exhaust system was hand built, all appart from the manifold section which was purchased off of ebay for around £5.

Would love to see some photos of what you have and how far you are already, if you could PM me some or email??

Some more videos for everyone to enjoy (i hope)

This time at the Vale of Aylesbury Model Engineering Society....which i am now a member of.

Let me know what you guys think.

I usually regard 7 bogie coaches or 14 decent sized four wheelers (i.e. not slate wagons or Hudson skips) up a 1 in 35 gradient a pretty stout test of haulage capacity. A R/H 'Millie' will usually walk that if the track is straightish, but it gives some other types adhesion problems.

Good stuff, thanks - I like the bodywork you've built, and it doesn't seem (hard to judge on video!) quite as noisy as I would have thought. What's the thing sat on the cab roof, please?

Hi Richard

Thank you very much, and i find that the camera actually exagerates the noise sometimes.

The wires and 'thing' coming out the top is actually the control unit (potentiometer) which controls forward speed. I currently dont have anywhere to put it, as when i turn it, the loco emediately starts running away from me, so a hole in the roof, where the glow starter can poke through and start the engine with body on, seemed like the perfect place to place it.

Hi Guys

After seeing someone else play around with AC forms of generators instead of DC, I decided to give it a go....and well its worked for me...which is unusual, as usually the first time I try something with models, it fails....

Im now using a clutch, a brushless motor from a plane, and some gears, instead of a straight 1:1 coupling.....so this time, the loco is remote control, and starts to move with engine RPM instead of potentiometer control, which frankly was rather bad, as you must have seen in previous videos, as the diesel is constantly running away from me.

Below are some pics and videos of whats been changed...and the loco running on a  test track in the garden.

Ive also nearly completed my third live diesel locomotive now, which is being powered by a 40 size 4 stroke model aero engine...so please stay tuned for when that come out the shed.

Enjoy

As promised, ive made some more videos, this time at the club, and pulling and shunting wagons and coaches up and down gradients. 32 axles piled with real wood batons seems pretty good to me, please let me know what you guys think.

That's pretty damn impressive mate. Keep it going!

Hi Guys

As promised, ive finally managed to get the basic concept of my twin bogie BoBo live diesel locomotive, using my OS FS four stroke nitro engine.

I may be wrong, but from the research that I have done, I am either one of the first, OR THE FIRST PERSON, to make an Electric start, 4 stroke live diesel locomotive, as all others using the 4 stroke I believe were pull start.

It is a very basic layout at the moment, and was really just to test out my scratch built chassis (made using shelve units) and the Electric start of the 4 stroke, and how to couple it to my generator.

After looking the very fine craftsmanship, seen in the videos produced by David (dewintondave), I agree that although the noise o=from the four stroke is much more acceptable and scale, then the 2 strokes ive been using, it could still do with silencing some more, and i do plan on building a exhaust pipe out of copper pipes of various sizes in due course.
