Do wood screws go into the bulkhead without splitting the plywood? I purchased AMW/ProX's 1010 Delrin low drag rail guides (very nice buttons) BH type that come with wood screws. I'm trying to install them on a Madcow Mozzie however there is a concern that the wide wood screws will split the narrower plywood bulkhead. The plywood is nice but not terribly thick. Am I missing something?
