Doddys HaupWerkstatte - My build thread
« on: March 02, 2018, 10:42:38 am »
Plans are afoot!

The RS540 specification brushless motor and the Quanum 2208 Brushless Motor have arrived from China and the UK. The RS540 has FET (Field Effect Transistor) feedback for connection to a an ESC (Electric Speed Controller) based Brushless Controller with FET inputs, the Quanum comes without FET's, as does most Radio Control equipment on the market.

Whilst waiting for some remaining items to be delivered, I wanted to see how they fared physically in relation to Gauge 3 back-to-back wheel dimensions, although the main plan is really to test their slow speed control potential for model railway applications before I start making any decisions on manufacturing gearboxs and mounting frames.

Here they are seen in comparison to a set of G3 wheels from GRS - Ref: Slaters Plastikard G3125 Gauge 3 (G64) Coach Wheel 3' 7" Plain Disc

Here they are with the RS540.







And with the
Quanum 2208







The Quanum 2208 was selected for its small size potential for use in very small locomotives and Electric multiple Unit rolling stock where you don't want the motors intruding through the floor. Like these Isle-of-Wight, ex-LT1938 tube vehicles which have very small diameter wheels, typically in the region of about 2' 6" . . .



The RS540 was selected for my ADtranz 12X locomotive test rig where more power is required. This project was initially documented in this thread - http://g3forum.org.uk/index.php/topic,2087.msg13549.html#msg13549

The Brushless Motor Test Rig (barring acquiring some remaining cables) is almost complete parts wise, and nearly ready to be assembled to test various motor/controller combinations.



This build thread will be added to with my experiences with Radio Control, Digital Sound and of course the locomotive builds - providing I can find a suitable means of propulsion.

All very interesting, and now you have got me thinking about 38 stock in our scale!

You'll have to build it with air-operated doors (or at least simulated air operation)!
To be realistic they will have to open and shut several times before the starting signal bell will "ping".......memories of the Northern Line commute from Morden in the 1960's!

It's certainly very ambitious Doddy - but why not?

It's Gauge 3 and we have a lot more room for interesting stuff on board...    :D

Interesting...

I saw those hoppers at Walsall... nice...

Digital Sound and the Deltic
« Reply #6 on: Today at 07:30:05 am »
For most, the evocative sound of the Deltic commands attention. Up close, the throb of the engine creates reverberations in your chest. But how to record the Deltic? Unknown to many is that the source of the engines howl and beating comes from each of the two engines respective air intakes. Problem is, the exhaust is on one side of the locomotive and the air intake is on the other.

The use of close-micing and several microphones allows a multi-track synchronised recording that can be edited later.

This is myself and Kevin West being filmed, recording 55 019 whilst under static test, previous recordings were made on the steep bank of Barrow Hill including the overload shutdown whilst under acceleration which made me reminisce being back on Stevenage new town station as the 14 coach Down 'Aberdonian' pulled away north on its evenings run up to Aberdeen.

The next step is to create and edit the digitally recorded samples and load an ARM 7 processor chip with 24bit (studio quality) sound.

I can only once recall having experienced the sight and sound of a "Deltic" in full flight (I lived in the far South near Battle and was more accustomed to the endless rattle of the Hastings DEMUs).

Was around 1968, while sitting on New Barnet station, when I saw an UP express approaching in the distance, along the straight track, and the ground shook as it got closer.

A big contrast to the Cravens DMU which had taken me there from Kings Cross, to attend a hearing in the County Court...... it struggled to get started and limped all the way, the driver having more than once got down from his cab and hit something underneath with a spanner!

The next occasion I had cause to travel North was to Leeds but by then the HST 125s had taken over.... a shame but the restaurant car breakfast was excellent....all paid for by the firm! One thing I recall about the 125s was a dreadful smell under hard braking......must have been something to do with the composition of the brake blocks.

John.

You can imagine how knackered I was then travelling out from and back to Stevenage every weekend by Class 105 Cravens. All stops KX to Stevenage.

And all that after visiting KX, St Pancras, and Euston stations, 3rd rail Class 501's or LT1938 stock out to Queens Park and Willesden Jnc for Willesden Electric Depot, Hymeks at Old Oak Common and back to Paddington for the evenings departures with Westerns, Hoovers and named WR Brush 4's.

Indeed, I had thought the Hastings units were bad enough until I had experienced the GNR suburban service!
At least the Hastings trains had a buffet car to ease the agony!
