Here's a picture of the new stabilizer. I have the leading edge tubing clamped in place while drilling the countersunk holes for the brass screws.
Here's a picture of the entire project (less wings). When my oldest son asked "Dad, where is the fuselage?" I pointed to a big bucket full of the precious fittings. "In there!"
The stabilizer and ailerons are from a Canuck, which differ from the JN4D. But, the methods of construction are similar.
