Taming Brass

 

I had something of a pleasant surprise today: my latest AFV is decked out with photoetched brass, something I would never have expected. Brass has never behaved for me and I didn’t expect it to this time. But… That Trumpeter M1126 Stryker came with a beautiful fret in the box, and I thought I might as well give it a shot, as there were alternate plastic parts if the brass wasn’t cooperative. I’ve used PE before, of course, I’ve added screens and grills on three previous models, but folding brass has so far defied me. Maybe I started out on the wrong foot… The Airwaves set I picked up for my Academy Merkava II was simply too hard to fold with the old standby, two single-edge razor blades, and I had not heard of the annealing trick at the time, so the PE more or less ended up back in the packet with a big question mark hanging over it. With those memories, I approached the Trumpeter brass with trepidation, worked on basic theory and gave it a go, open to the possibilities but expecting nothing in particular.  

 Well… It cut where it was meant to cut, filed where filing was necessary, and folded where folding was called for. In moments, it seemed, some very tidy brass structures were on my bench. The only pain was the pedestal for the forward wire cutter which did not match the size of the recess in the hull, which needed filing out to accept it, and that may have been my fault for folding into the guides in the brass, instead of away from them. No matter, the fit was quickly adjusted with files. The only brass part for which I opted to use the plastic instead was the small shield part that goes behind the weapon station on the commander’s cupola, and that’s because the component is simply the wrong size. The plastic part fits (and was moulded remarkably thinly), the brass part never will. Similarly, the support under the starboard jerry can holder will also simply not fit: the locator slot is set too far back, the fold points result in a structure that would hold the rack away from the hull if located there. I filed the tab away and tried again but the support structure interfered with the plastic components directly below. The plastic equivalent was moulded as part of the plastic version of the rack, and I considered cutting it away… Another option would be to scratch the support from some light stock, which may be the easiest route. 

I found something of a lesson in this; one automatically assumes that hi-tech metal parts must be “better” than the plastic ones, but their accuracy can only be as great as the information on which they are based, and if they are the wrong size or shape they will never fit properly, no matter how sophisticated their manufacture. The cya bond between brass parts is surprisingly quick and strong, but the bond between brass and plastic seems lamentably weak: this model must be handled with the greatest care. If the brass parts, with the exception of the securely-snugged-down engine grills, end up falling off, I may retro to the plastic parts in the end, but the experiment has been very much worthwhile.  

 All told, I feel more charitable toward photoetch today than before. It’s a learning curve, for sure, to fold and trim tiny pieces of brass and steel, and I don’t see myself ever using much of what’s out there, especially when it crosses that line between adding necessary detail and “gilding the lily,” or what’s worse, overcomplication for the sake of it, but I can certainly see myself using etch at this level, to reproduce scale thickness and make from fine sheet metal those structures which are made from light sheet metal on the real deal. I don’t for a moment consider myself a brass-tamer yet, another few successful metal detailing outings and I might start to think of myself as one, but I’ve made a start… I find myself thinking about that Lion Roar set of turret armour for late Panzer IVs I picked up last year, and can actually see me getting my clumsy fingers around the job after all! More on the Stryker when the paint goes on.
