Looking through old NG Gazettes, I spotted this plan of a Surrey Parker loader. I had a friend blow the drawing up to 1:20.3 and started the build. I deviated from the plan in a few places, but kept the same dimensions. I also photographed a build log for a friend who wanted to build one as well. So I cut two pieces of everything and made up a kit for him. If anyone is interested, I can post the pics here.
A few pieces of wood, and an order to Ozarks for some pulleys, etc I was ready for the build. I had an old Ozark steam donkey I built years ago laying around and decided to use that for the loader.
