Graham Farish N Gauge WD 2-8-0 Austerity DCC Sound (Zimo)

The Graham Farish N Gauge WD 2-8-0 Austerity - installation guide for DCC sound using Zimo MX648 and SugarCube7 speaker...

Here's our donor before starting work...

4 screws underneath allow us to pop the tender body off, revealing a lot of potential space.

Our intention... to fit a Zimo MX648 sound decoder and YouChoos SugarCube7 speaker. We could probably even get a full-sized 9mm SugarCube in here, but the 7mm is plenty loud enough and bassy enough for N gauge. We remove the DCC socket board.

The unwanted function-related wires have been removed from the decoder for neatness. To create plenty of height, we've cut a rectangule hole beneath the coal load area so the decoder can sit higher up. Unlike many recent Farish tender models, the WD has a pair of solid metal bars where the pickups are connected, including 2 screw-pillars where we can easily attach our decoder's black and red pickup wires. To make this even easier, we can recycle part of the DCC socket board, chopping the 2 screw holes out of it and soldering our black and red wires before screwing into place.

All soldered up, placed in position (thin double-sided sticky tape is great!), electrical tape over the pickup bars, this should go in really easily...

The decoder sits up in the rectangular hole we cut earlier, but not too high.

We could just put the original plastic coal load back in, but the tender is quite low on weight, so we cut a couple of strips of roofing lead, insulate with electrical tape and place those on top of the decoder.

Black-Tak is an excellent material for filling gaps, and has been used to great effect here around the edges of the wrapped lead. With some teasing, an interesting shape can be created for the coal ballast to be attached to.

Some crushed Woodland Scenics Coal Ballast is glued on top and spread to satisfaction.

One of the easiest DCC sound steam fits ever... here's the final result...
