Side Panels and Louvers

My schedule changed a bit so I met Russell Sanford at the hangar today instead of Wednesday. We attached the right side cowl door and measured the cutouts for the louvers. The Curtiss drawings are for the JN4D2 so they were not much use. We spaced the first two louvers 3 1/2 inches apart and the last two 4 inches apart.

Remember - leave room for the hinges, beading and Murphy fasteners!



I found the quickest and easiest way to cut the slits for the louvers is with a thin die grinder disk.



First, drill two holes at the end of each slit. (The drill bit should be the width of the cutout disk.) As a guide, I used a .100 piece of steel.



Nice straight cut! The edge has a little cutting slag on it, but can be easily removed with a small file.



Here is how the louvers are made: Take this louver shaped die and hammer it into a 1 1/2 inch opening in the jig. Simple and effective.



It fits like this.



Line up the slot and clamp to the jig. Hammer the die with lots of steady hits. Don't whack it. Just tap it steadily.



Tap as you slide the die across the opening.



A finished louver!



I peeled the protective masking tape from the louver to show you the results. Sorry, I didn't want to risk scratching the burnishes!



Ran out of time at this point. Hope to continue louver making later in the week.

Enjoy

Brian
