Alan's grubby little shunters thread

[Galteemore]

That’s looking great Alan, and a nice solution.

Hunslett now has pickups. 31swg phosphor bronze wire shaped to hook over the wheel flanges at the top. Since @Northroader (I think) suggested this method somewhere a while ago, I've been using it and it works well. The hook keeps the pickup wire in place and there are two possible contact areas - wheel flange and wheel back - to keep things moving along.

 

Each brake hanger has 2 bits soldered together. The RSU did this job very neatly

 

Brake rigging is 0.45mm brass rod

 

The whole nine yards - pickups, brakes and sand pipes. Phew!

 

Trial run under DC at Loughan Quay. Bodywork isn't secured yet.

 

Hardly any burnt fingers today

Very smooth! And it looks at home on the quayside.

I'll look for a grubby one!

Cleans up nicely does Hunslett

 

But nothing like a coat of primer to show up where the filler needs to go.

I must have squandered about half a mile of brass rod getting those handrails the way I wanted them.

 

I'm never entirely happy mounting chassis with bolts front and back, given the chance that tightening both could twist the chassis. So this one has a bolt at the back and this little bit of bent 1mm brass rod at the front which locates into a slightly oversize hole in the front chassis spacer.

 

Chips soon

Very elegant solution Alan. Agreed - the fore and aft bolts can cause all manner of issues

He's a very handsome little fella Alan! You've done a wonderful job (as always). He really looks at home in that setting too.

There's a surprising amount of free space inside this Hunslett so a sound installation looked feasible. 

The sound chip was hardwired with all the joins covered with heat shrink sleeving. The speaker wires are connected to the chip via a mini-plug & socket arrangement which will allow the speaker to be permanently mounted and un-plugged if/when the chassis needs to come out.

Testing the wiring. Despite a 50:50 chance of getting it right first time, I invariably wire the motor terminals the wrong way round so that it runs backwards with the controller set for forwards. Easily fixed but irritating.

 

Yes, it all fits. The speaker is in the cab where the backhead should be (can't be seen) and the chip and stay-alive capacitor are in the boiler.

Paint next.

Alan
