Can you take a stainless cane with 3 mm in diameter and drill a hole of 2 mm alongside the cane at the depth of 3 cm? It's fine if you can. Now let's take a cane with 2 mm in diameter and drill an ideal 1 mm hole at the depth of 2 cm. Mind that you don't have any power drill at your disposal but only a primitive hand brace used in 1970. Will you be successful this time? Hardly.
But there is a man who will. He has done it many many times.
He is a historian, constructor, woodcarver, jeweler and the only master making miniature copies of shotguns and cold weapon. "The Kalashnikov Gun".
Over 30 years ago Alexander Perfiliev drilled his first longitudinal hole in a miniature Mauser copy with a hand brace. In 1979 he was busy with making the first exhibit for his future collection of small-arms in miniature. It was a tiny Mauser. Some models are very complicated. Thus, it took 1 year to make a copy of the Mosin rifle. Most models are made of steel. Though, in case good material is lacking it's possible to use whatever is nearby.
