Once the cucumbers start coming they don't stop for months. I don't know about you, but I can't eat more than 1 or 2 a day. The rest we pickle. The blossom end has enzymes that will make the pickle soft, so it has to be removed.
2 gallon crocks are a good size. Use canning & pickling salt for the brine. 1/2 cup of salt to a gallon of filtered water is the ratio for a basic brine. The oak boards are to keep the cucumbers submerged for good lacto fermentation.
Some of the things that you can place in the crock are: dill, garlic, peppercorns, and grape leaves. Bay leaves, mustard seeds, and red pepper are good as well.
