0-4-4


0-4-4 Chassis

OK – This project has been sitting around part complete for several months and now I need to get it ready for handing over on the 20th. These things really creep up on you don’t they ?

The job – Test build an etched 7mm scale locomotive kit for a Midland 0-4-4 for Trevor. He’s bought it in and before it ends up in the range, someone has to see how good it is. That’s me then.

Starting with the chassis, this is a pretty simple beast. Ream out the holes for the bearings, which are correctly etched undersized as it’s easy to make holes bigger, a b@&**er to make them smaller. Once these are soldering in place the sides are brought together with the chassis spacers.

You can tell the age of the kit by the fact it’s designed around screw in spacers rather than etched versions. This isn’t a problem as long as the sides are identical. Once I was happy that all was square, I solder the spacers to the sides. Ideally you files the heads of the screws flush and cover them with solder so they can’t seen when the model is painted. I files but didn’t fill as it’s useful on the stand to be able to see what you are getting. Actually they will hardly show anyway but never mind.

The cross wires for the brakes make the whole thing permanent – which is good, we don’t want the chassis disassembling itself later do we ?
