Their first project was a World War II-vintage Sten Mk II submachinegun. These 9mm SMGs had a very simple design using a tubular steel receiver. Parts sets for the guns (sans receiver) were cheap and plentiful. Finding several ads in the
When the greasy parts set arrived, Fong was a bit disappointed by its condition. Several of the parts had rust pitting, and Fong pointed out that the stock extension was slightly dented, so it wouldn’t fit on the receiver tube blank. Ian laughed and said, “Don’t sweat it, Dan! We’ll just cut to size, file to fit, and paint to match. It’ll be easy!” Assembly did indeed turn out to be fairly simple. Aside from a touch-up weld and final finish, the Sten was built in just one weekend.
Their next project was more ambitious: an Ingram M10 submachinegun. Like the Sten, its parts set came from an ad found in the
Welding together the frame and assembling the M10 took the trio just one day. The time-consuming part was making the parts for the sound suppressor that attached to the M10’s factory-cut muzzle threads. The suppressor was a clone of the famed Sionics brand, which was codeveloped with the Ingram SMG in the 1960s. The suppressor project took several weekends.
Dan and Ian started with a set of Sionics machining diagrams that they found advertised in
The final touches in the welding and painting of the two guns were done in Michigan. This was because Todd’s mother objected to the smell when her kitchen oven was used to cure the Alvin high-temperature engine paint that was used on many of the gun parts. Over a three-day weekend, Todd, Ian, and “the Fongman” took a road trip to Plymouth, Michigan, and worked in the garage at the home of Doyle’s parents, who at the time were away on vacation. When he had been invited to join them, Tom Kennedy declined, declaring: “I don’t know what your fascination with full-auto is! I can squeeze my trigger finger pretty fast, and
The last-minute welding work in Michigan included attaching the front strap hanger for the Ingram and touching up the trigger-guard welds on the Sten, which Fong had declared “imperfect.” For this they used Gray’s portable oxyacetylene torch, which they brought along on the Michigan trip. This was the first time that Todd ever helped Ian and Dan do any of the welding. The paint curing was done in the oven of the Doyles’ “summer kitchen” fruit- canning range, which sat in the screened back porch. The welding and painting weekend in Michigan turned into an extended pizza and root beer party for the trio.
Later that school year, Dan and Ian drove to the Upper Peninsula of Michigan to test their two new toys. They did so at Porcupine Mountains Wilderness State Park on a rainy weekend. Hiking deep into the forest for two hours on deserted trails across patchy snow assured them privacy for test-firing the guns. First they fired the M10 using special subsonic-velocity ammo. With suppressor attached, each shot sounded like little more than a hand clap. They fired just sixty rounds through it, mostly with the SMG’s selector switch turned to the semiautomatic position.
