I work in brass (and aluminum or steel or bronze…) when it is the best choice for the parts being made. I do a lot of fabricating with styrene, but there are some parts that can be made better and sometimes even faster or easier in metal. As mentioned, the stability of metal is superior to plastic not only in larger sized parts, but in tiny parts as well.
The frame on my Seven would never have worked (survived) if it were built up from styrene. In fact making it in styrene would have been unimaginable harder to do. It had to be brass, not aluminum, so it could soldered to as I went along. All the hardware and fasteners I make are done in aluminum; stronger and easier to maintain uniform tolerances than in styrene.
Some builders like to showcase their metal parts by leaving them in raw finishes. I prefer to finish them to look like the real parts could have looked, sometimes that is raw and other times its paint or a dozen other options. Even if the metal part(s) can’t be seen they provide an often much needed strength and uniformity in scale that can be difficult to achieve with only plastic.
The wheels have been cast in resin, painted and weathered. The tires are Desert Dogs that I sanded the lettering off of. The size and tread pattern is a good match for the Remington’s I had on it. I’ll add the sidewall lettering and center caps later.
If I build it, it will be for my friend who gave it to me. But I will check to see if he has room first. I've ready done a model of his Continental 737; he was the pilot that took delivery of the very first Continental 737, and the Minicraft kit builds it straight from the box. (With the Scale-Master decals...)
A friend of mine had to clear his attic for a new furnace today and found these four kits. He decided he'd never build them so he gave them to me. He used to fly B-47s and B-52s. He used to have a '63 Corvette and an early Pantera. I'm sure he planned to make replicas of his rides.
I bought one many years ago, I still have it and rarely use it. I tried all the different nozzles and found it doesn't work very well for paint at all. Even when charged fully it doesn't spray for long as the material is depleted so is the pressure. So to empty the canister it needs to be recharged with more air pressure a couple times. The spray pattern and volume changes quite a bit and quickly.
The best use I've found for it is for spraying cleaning chemicals/solvents. But even then it is a hassle to fill, charge, recharge & clean.
I made the side windows from sheet styrene, some clear plastic from packaging material and fine screen. They are just loosely plugged in for now.
The rear “window” was a piece of unfinished dirty plywood. ( The clear plastic window turned white, cracked and ultimately fell out within a couple months of owning it.) There was a silhouette of the Stealth Bomber left from when I painted a model of one on the wood (when the B2 was still somewhat classified). The Kammback script was a leftover badge from my Vega.
