After another failed crusade with sweetie belle and scootaloo, she gets a school project on reperposing damaged items. So she takes an old gramophone, some broken shovels, and a bent plow, she accidentally creates an automatic digger and gains her cutie mark in machinery, she faces changelings, changeling, and more changelings.

Warning: this is my first fanfiction, story beyond this will manly be based on the cmc or diamond tiara or insane twilight or ponies being transported to other worlds or techno bloom, (my name for this type of apple bloom) and probably after this I'll make an evil version of this concept.
