Re: Converting old locos to dcc

With the bulb, yes, across the output so it forms a parrallel circuit with the track, it should give a steady draw on the controller and stabilize the readings. for the different decoder, what i was meaning was fit it into the driving end along with the TTS chip, so the TTS chip works just like the ...

Re: Converting old locos to dcc

As Brian says it can be a feature of the controller design that means under no load modern meters dont give accurate results. One way that you can normally stabilise it is to fit a constant drain to the supply so you have controller a light bulb then in parallel your electronic meter which is connec...

Re: Laser Cutting

My issue with printing is i have no experience in 3d drafting but 2D is rusty but possible. My thoughts for the very slight curve at the bottom of the sides was to simply use a material that would be thick enough to sand/shape to the correct profile. currently working on the bulkheads as that turns ...

Re: Manufacturer "drawings"

There is plenty of information on various manufacturers web-sites about radii of curves, dimensions of track, lengths of vehicles and such like, and as some else on her is wont to say Google is your friend. Modellers web sites frequently have useful information, especially within some splendid revi...

Laser Cutting

Just wondering if anyone has much experience in using laser cutting services? Ive made a CAD file of the DMU sides and wondering about laser cutting to get a nice accurate shape, smooth curves etc What material would be best? or would developing the drawings into a 3d for printing be a better idea? ...

Re: Danderhall

So a little project to try my hand at something more complex, Creating a NIR Class 80, so from drawings found online created into a wooden template and then after checking the look and dimensions copied into CAD. the plan will be to laser cut it after a house move so this is the research and testing...

Re: New layout but no name yet

Looks excellent, the detail on the engine shed certainly captures the worn and tatty image.

will follow with interest

Re: DCC a Hornby R070 TT?

For the motor control if you can do it so that every track is equally spaced then it will be much easier as you can rely on the accuracy of the stepper simply to move 'x' steps without any need to fit feed back for alignment. for connecting the Arduino to the DCC one option use a standard loco decod...

Re: Hornby Track Plans

Hi Chris Going slightly off topic, but I have a turntable (Peco) at the end of my fiddle yard. As my coaching stock has Kadee couplers, and with magnets placed under the track about a loco's length from the turntable, you can un-couple, turn the loco, run down a track kept free of stock, and re-cou...

Re: Danderhall

Well why did I think that a coronation class would accept a coronation class tts decoder without a fight, 'may' need to modify the weight is a slight understatement. Anyway it got in and tested successfully and then packed away in a box. That is the end of the modelling for a few months as I go away...
