If it was a real shop with all equipment being used at one time , I'm not sure what would happen . If you haven't watched David Richards, Old Steam Powered Machine Shop on Youtube, I recommend it. He has his shop set up like a shop in 1935 would have been . Heck , most of his equipment dates to 1935 or earlier. At the first of his series, he powers his entire machine shop with a very small horizontal engine through a series of line shafts. His little engine just loafs along powering the entire shop with seemingly no effort . Later in the series, he installs a much larger mill engine in his shop , not because he needs it, but just because he wants it. Like he said, it is overkill , and would run a saw mill , but it will also run his shop ! That being said, he doesn't use all his machines at one time. Usually no more than two or three at once . I forgot mention, but I named the little guy using my band saw David Richards .
