RE: Adjustable flap and elevator
That's a great looking handle! There is probably a small market out there.....I have been using the Ted Fancher type handle. I bought one from Ted and then a couple more from Carl Shoup after he took over making them. It's a laser cut wood handle with sheet steel tabs the lines attach to. I should send you a copy of Ted's instruction sheet for using the handle. It's a real eye-opener about the importance of the right handle correctly adjusted.
Well, it has been snowing steadily here since midnight and is expected to continue until noon tomorrow. At one point we were getting 2-3 inches per hour. It took two of us 45 minutes to shovel our one car driveway. Plus the wind is 15 to 30 miles per. Welcome to spring!
