[WH40K] Is Ork technology, in the smaller sense (shootaz or battlewagons) possible?

Let's say you were in a junkyard, scrap metal, electronics and parts from most household appliances and servicable parts from 1 of each type of car (SUV, 4-door, truck). Could you recreate Ork technology without the innate warp ability they have?

Some aspects you could create fairly easily. Lots of junkers and home survivalists can make your typical Mad Max-esque combat vehicle, which is what most Ork trukks are. And I've seen more than one gallery of someone taking an old bulldozer and turning it into a tank. 

Guns would be a bit harder. "Looting" weapons would be easy, but trying to build/upgrade them is mostly out of the question. Don't think you could build a tank gun for your bulldozer tank... maybe a flamer, though.

Red won't make this stuff go faster.
