Much of the work involved in making a model is preparation rather than construction. For example, I've made a start on an O14 Hudson Hunslet kit by Nonneminstre Models - which involves preparing the white-metal castings for the chassis to ensure a good fit before assembling them, and filling any gaps. As the prototype chassis is a single, massive casting rather than the five pieces of the model, I've taken the unusual step of giving it a coat of primer before proceeding further with the build so that I can see any remaining gaps and imperfections, and treat with filler and emery paper.
I'm planning to adapt the kit as per the Thakeham locos, but while I have plenty of photos I don't have dimensions yet, so this may sit on the back burner for now.
At the same time the Hudswell Clarke 009 loco has been primed. First I blackened the nickel-silver which both helps paint adhere, and disguises any wear or nicks in the paint along the edges. Then any gaps are filled - I find Squadron Green Putty ideal - before the model is cleaned. A couple of coats of Halfords etch primer are then applied, and once hardened the model is examined and any visible gaps or imperfections seen to with more filler and emery paper - before another coat of primer.
Meanwhile I've started yet another loco kit - of which more another time. However the build starts with preparing the N-gauge loco chassis - which means dismantling it completely, and chopping it up. As you can see that means a fine mess, I hope I can get it back together again - and working!
