That it works at all is testament to the power of the Ork Waaagh!, as it's peculiar psychic field allows them to bypass the physical impossibilities that would ordinarily render their gear useless or broken, simply via belief. It should be noted that the bulk of their 'technology' is so incredibly crude that its ability to function would apparently contravene not only common sense but the laws of physics as well a given shoota is, more than likely, literally slapped together out of scrap metal, leaving it by rights incapable of firing. Although incredible as it sounds, this knowledge at its peak actually surpasses the Imperium's technology levels. It is less intelligence or skill, and more instinct, as their relative wealth of technological know-how is actually genetically engineered into them, and is expressed in their trademark crude and ramshackle style of building. Mekboyz are an interesting example of the Ork race because their abilities with machinery are not a learned knowledge. Important Mekboyz are known as Big Meks, who lead groups of lesser Mekboyz armed with all variety of kustom equipment and combi-weapons, sometimes even warbands or whole Waaaghs! armed with a better percentage of less than conventional orky weaponry. Mekboyz are especially important to Speed Freeks, as they maintain their prodigious amount of bikes and vehicles.
