Time: 3 Hours
I got in the shop today after my weekend breakfast with Glenn for a couple hours. Today’s task was to make the wingtip hinge pin stops. These are made from a scrap plastic cutting board of all things. This is a pilot designed mod that has been used by many builders so I’m just copying their ideas. The idea is to cut the hinge pins so that they are a length that will slide into a chunk of the cutting board. Then that chunk can be screwed into the wingtip rib with a nutplate. Sounds weird but photos will help explain it. First up was to match drill the rib to the wingtip like I did on the right side.
Then I drilled for and riveted a not played 2 inches from the tooling hole. I’ve been shaped a piece of the cutting board two inches long into the shape of the rib.
I clecko’ed the rib in place and reinstalled the wing tip on the wing as well as remove the aileron jigs so I could move them.
I removed the block and drilled tow #40 holes in the forward end of the block for the hinge pens to slide into. I marked the depth on the outside edge and return the block to the rib to mark the hinge pins to cut. After the pins were cut I return them to the wingtip and slid the block over each of the pin ends and screwed the block to the rib.
