Shoeing horses was the majority of my work back in 1885. And I would also fix broken wagon and carriage wheels and axles from time to time as well - though I imagine you don't have very many of those. I have plenty of experience working with internal combustion engines, too, should you have any ATVs or trucks that need fixing.
But I feel like I should introduce myself properly! My name is Doctor Emmett L. Brown - though I suppose the 'Doctor' bit isn't exactly valid in this world. Man of the physical sciences, not of the medical profession. Originally from the year 1985, though I came through the Tesseract directly from 1885 where I had been living for several months due to a time travel accident.
