Coach Lighting Part 3

 

28/12/2024

Finally I've tested the fit of the components into the underside of the seating unit; they fit quite well into the recessed parts where the seats are moulded. As this is a brake van I've put the 2x1000uf capacitors connected in parallel in the goods compartment they will actually fit into the toilet compartment of a corridor coach. Components now glued cables rooted I am waiting for the pickup springs for the axles but I've managed to test it on DCC like clipping the wires to the rail. I need to re spray the roof to eliminate the light bleed. Next coach will be manufactured by Mainline who use a different construction technique. 

I need to re spray the roof to eliminate the light bleed.

29/12/2024

Roof re-sprayed this morning and fitted 2.0mm Pickup Springs I polished the axel with a ‘track rubber’ to endure good electrical contact. I stuck a 25mm wide strip of ‘speed tape’ (it is thin self adhesive aluminium foil) to the underside of the roof as a precaution to prevent light bleed though the roof of the Lima model then I stuck a 10mm strip of plastic card with 3 blob of hot glue this is important because the foil is conductive this and the re-spray stopped the light bleed that’s one positive.

Coach Lighting Part 2

 

27/12/2024

I constructed a “bridge” to support the LED strip inside the Lima BSK and painted the interior seats. Some of the components have arrived in the post and will allow me to test on the breadboard I know it looks “Heath Robinson” but it worked the LED’s slowly diminish when the power is removed.

Coach Lighting

I thought it was time I installed interior lighting into some of my coaches. I checked the wheels on my coaches and I only have 12 wheel sets with “live” axles. I chose to start with a Lima BSK first introduced in 1977. I thought the following circuit may give a flicker free setup. BR1 DB103, R1 3.3k, C1 2000uF and 32 AWG wire duly ordered and a 12v led strip which I already have BUT be warned this circuit is for 12v strips only! When the components turn up in the mail I will test on a breadboard.

Dapol Class 121Slipping Drive

 18/12/2024

This is the second time the drive shafts have failed! The knuckle on the end of the shaft just slips. Unfortunately there are no spare parts available at the time of writing. Fortunately I have the old set from the previous failure I cleaned the parts in isopropyl alcohol run a triangular needle file across the mating portion of the shaft and glued the knuckle with cyanoacrylate. That didn’t work Dapol will supply them on an exchange basis. So the loco and the defective drive shafts are going back after the holidays

 UPDATE

Replacement drive shafts have arrived back; I’m glad to see that the design has been changed. To my mind this is a much better design.

Restoration and rebuild of Western Hills station part 2

 

I Sprayed the completed lights poles with Halfords rattle can Rover Damask red which is a close proximity to LMS maroon, next is to fit all those fiddly little LEDs. Meanwhile I've sprayed 18 GWR style platform benches from model railway scenes with Halfords rattle can Rover Russet brown a close proximity to GWR chocolate.

Restoration and rebuild of Western Hills station

 

14/12/2024

 Continuing with the restoration and rebuild of Western Hills station I needed some station lights I have a bag full of cheap and cheerful eBay station platform lightswhich are a scale height of around 10 feet. They just don't look right so I decided to use evergreen plastic extrusions to fabricate some new lights. They will be a scale height of around about 14 feet I commenced by cutting 3/32 inch round tube to 67 millimetres long for the pole next I need a base so I used 1/8 inch square tube bored out to 3/32 inch to length of 15 millimetres lastly a collar made from 1/8 tube two millimetres long again bored out to 3/32 inch.

Assembly quite straight forward slide the square base up the tube leaving 15 millimetres protruding.  Slide the collar on the top leaving around 2 millimetres protruding run liquid cement around the joints. The next task is to disassemble the cheap and cheerful Chinese lights. All we need to keep is the globe and the top cover. I cut the spigot off the top cover which allows them to come away from the pole.

For the light source I used miniature micro LED’s type 0402 pre-wired from eBay they are so very tiny.

Bachmann Webb Coal Tank 7841 sound fitting

 10/12/2024

7841 is now fitted with a Zimo MS581N18G sound chip and a Sugar Cube SCUBE8 from https://www.youchoos.co.uk/. The speaker fits in the space beneath the bunker after removing the spacer! It must have spring clips (not solder pads) there is no wiring just plug and play. I took the opportunity to fit some crew from the modelu range the terrier crew fits into the cab nicely.
