Re: Switch help

Harping back to the microswitch question. I found that the lever type microswitch at least had enough spring in it to move the point mechanism against the resistance of a Hornby or Peco surface mounted motor, so unless your wire-in-tube system has a bit of friction in it then microswitches may not b...

Re: Point motors

Harping back to Hornby surface mounted point motors. If they are not perefctly aligned with the track mechanism the turnout tie bar pin can catch on the motor housing. Give the tie bar pin a bit of a file and it will stop it catching.

Re: illuminated writing on factory chmneys

Once upon a time in a previous life I used a giant piece of test kit, which had indicators that illuminated to show various pass/fail codes. These codes were in fact engraved onto glass and were lit up as required from their edges using lamps. Bring this up to date using perspex engraved with your l...

Re: How do you make a train wait at a red signal??

Hi Suitable decoder is one which supports ADCC (assymetric DCC signals) such as Hornby Sapphire or Lenz silever/gold, maybe others. ADCC is not quite the same as brake on DC. ADCC works with any command station as the 'intelligence' is in the chip. Simplest way with DC to stop at a red light is usin...

Hi
Hornby Sapphire chip supports ADCC which is what Lenz BM's use to slow/stop/start locos automatically.

Re: Point motors

Hi The Elite provides more spare power than a Select due to its 4 amp power supply, but the Hornby accessory decoder stores up the oomph to fire the motors by way of a built in CDU, which isn't really that brilliant and the reason I stuck with analogue method of point motor firing using a Gaugemaste...

Re: LENZ BM-1 - How compatible are they?

I can confirm that the Sapphire works with ADCC as invoked by the Lenz BM1 module, although being tight fisted I made my own with a bit of veroboard, 5 diodes and a dual terminal connector for convenience of connecting to the gapped rail (always the RH rail in direction of travel - ref Lenz data she...

Re: Hornby Sapphire decoder

Hi I've had a problem with a very early Sapphire chip. After a full system shutdown at next restart my DCC fitted Class 56 (original chip replaced) sometimes wont react at all - no motor or lights. If I put it on the programming track and read its address CV it seems to refresh the chip as it works ...

Re: Problems with the dapol cleaning wagon!

Hi
You should be able to run the vacuum motor from stopped up and down the full rev range in fwd and reverse using DCC if properly installed.
Just make sure the motor is connected to the loco motor feeds and not any of the accessory feeds.

Re: Your DCC System.

Hornby Elite
Only gripe so far is the control knobs can rotate as you push them, often selecting something numerically different to what you had punched in.
All very irratating and dead simple to fix with a click detent between each knob and the casing.
