Some thoughts about using this craft as a learning tool.
I like to mix up the pace on a long-term project like this box car. I’ll do a major sub-assembly like the underframe and then switch gears completely and work on a small detail. This helps keep my interest level up and gives a break from the tedium of doing the same thing for too long.
I want to extend my skills with this project and that’s the reason I’ve rebuilt components multiple times. I’m not happy with the initial effort and know I can do better. I have standards for the work. This is all well and good but if one isn’t learning from the mistakes, what purpose is being served?
After taking the underframe as far as I can for now, I worked on a small but important detail: the bottom track of the car door.
I put five to six hours over two days into this detail, which included making two jigs, one to shape the support brackets and one to hold all the pieces while I soldered them together. I also spent time figuring out the best way to make the support brackets (all 34 of them). They are a scale five inch wide strip of 0.005″ brass cut from a larger sheet. The door track itself is a length of 1/16″ brass angle. The delicate appearance of the prototype was an important quality I wanted on the model, hence the ultra thin materials. As mentioned, the brackets were formed in a jig and trimmed to size after folding using the same jig. After doing the first half-dozen, I stumbled onto a more efficient routine purely by accident.
Why am I in such a hurry?
I noticed I get in a rush to finish something when I reach the 70-75% completion point of a project. I guess I sense the finish line is near. This is a deeply ingrained habit that I fight all the time and this urge to rush takes my focus off the work. That’s where my sloppiness and mistakes happen
As you can see in the photos, the fit on some of the brackets isn’t the best. They aren’t seated firmly against the angle. These light pieces shifted at the blink of an eye, even when held in a jig. Soldering on a styrene jig can be done when everything is well cleaned and properly fluxed, so the solder flows instantly with the mere touch of the iron. I only had one mishap with excess heat melting the plastic. However, in spite of using an assembly jig, things still came out wonky.
Looking at the photos objectively, I noticed the top of the brackets are more rounded than I thought. For the second door track I took the time to flatten the bracket tops and this helped but there is still room for improvement.
The thinking process behind this part and the actual construction was very enjoyable. Watching it come together was as satisfying as it gets but, here we are again. If I’m not satisfied, do I settle or redo the parts? You should know the answer by now. I think these are salvageable with a little extra effort, if not, I’ll redo them. We’ll see later today.
Scratchbuilding is a series of decisions large and small. You have an objective you’re working toward. You have standards you want to adhere to but, often, the work comes up short. What’s going on? I think this quote from Ira Glass might help. It’s a short video, less than two minutes and, it applies as much to our work as any other.
