Re: twin electric motor drive
Permanent magnet motors (and parallel wound motors.) when fed at constant voltage, are in the ideal condition a constant speed device, they will draw whatever current needed to try to maintain that speed. Two similar motors ganged together, electrically and mechanically, will load share automaticall...

Calor gas
I have a great big tank full of really cheap butane and yet here I am buying camping stuff at over a fiver a tin. So the obvious question is; how do I get the calor gas into the loco?

Re: Electric turnout mechanism
Using electric central locking motors is a tempting idea. The old ones were solenoids, nowadays they have little geared motors in them. They are tempting because they are powerful, have about the right throw and work off 12V. The inside of a car door is not a dry environment so although they are not...

Re: The New Arrival - No.4 - a Roundhouse Bertie!
Tip I was given regarding fitting water sight glass fittings, is to use drill bit upended (or piece of rod) the same size as the glass tube so you get the top & bottom fittings aligned correctly before fitting the glass tube. Also melt the ends of the glass tube in a naked flame to seal them - ...

Re: Ragleth; adding radio control
I understand why Roundhouse et al use such big servos, moving a full or semi Walschaerts takes some effort, but the Ragleth control valve takes hardly any force to move. I have to say just how much nicer a Ragleth is with full RG. I tried it on reverser only but throttling it down, whilst it works i...

Re: Ragleth; adding radio control
Hmm! Coming to this as a noob, I had no idea which of the 1000s of servos on offer to use. So I looked at the utterly cheap, blue 9g servos I used for my foamboard RC planes. I looked at the specs and measured the force needed to move the controls on Ragleth and bought some better versions with full...

I have used smaller servos than the size that would be indicated by the spacing of the bolt holes on the running plate. The spec shows they have more than enough power. I have ground some sharp edges off the reverser that were causing a notchy motion and fitted a much lighter friction spring, just e...

boiler certificates!
OK I get it my engines work at 3 bar and need an up to date boiler cert.
But why don't I need one for my Kitchen aid espresso machine that has a boiler at 15 bar?
Just askin'.

When I did a RC conversion on a Ragleth I got the battery, Rx, on/off switch and regulator servo all in the compartment under the cab floor. As you are using Deltang this will be easier as I used a Ripmax Saturn Rx which is huge compared to the Deltang Rx102. You will need to drill the cab floor t...

Ragleth; adding radio control
Having successfully converted the RC on my Samson to Deltang based RC, which results in a much neater and more hidden installation, I am now looking to add similar RC to my Ragleth. Forward and reverse is catered for in the design, it is obvious where the servo goes, no problem. But the regulator? I...
