As per AC43.13-1B CHG1, Chapter 4, Fig 4-6, the proper rivet protrusion is 1.5D with a finished shop head of 1.5D in diameter, and .5 D in height.
This is the Bible per say, of aircraft sheet metal rules. D= diameter of the rivet
Its been some time since I posted last, but I'm at work by myself for awhile, and with the C-130 still in Chile, and nothing to do I decided I needed a battery box. I still need to make the integration pieces to the Globetrotter but the box itself is done. It will fit 2ea #30 batteries. Below is the final assembly pictures.
HOLY COW! Is THAT your garage??! I'd LOVE a shop like that. That battery box sure does look government spec. My friend's business makes electrical chassis boxes for some of the military helicoptors / planes... VERY nice work Kip!

Are you building a prototype here for a defense contractor? Is this going to be the escape pod for when the society collapses? I am very impressed with your abilities Kip. Keep up the good work.
PS bring us back some of the Chile wine on the C130
Hi Kip, I am sure the if I could wait you will have pictures, But my curiosity is killing me. Where do you plan to install the box on your Globetrotter?

I am changing the interior lay out to have a dedicated bed in the back where the bathroom used to be. So the battery box will be going right behind the axle, on the curb side, and will be under the bed. It will be completely sealed off from the living space and vented outside. It will also be raised 2" from the floor so that the exterior molding will not interfere with the swing down door.
It was snowy and cold today so I decided to work on the tail lights. The castings were pretty corroded so I sand blasted them first to clean them up. The assembly was originally pop riveted on and as stated before I hate pop rivets. I layed out a pattern and drilled to a #7 and then tapped all the holes with a 10/32 helicoil tap and installed 1D self locking helicoils. The original light cans were removed and LED lights purchased. The holes in the housing were about .050 small so I sanded them to size with a 2" sanding drum in a 90 degree die grinder. Needless to say this took some time and made a big mess.(around 1 hour per hole). On the LED lights that I ordered, I had to sand off a small lip from the circumference. I also had to cut away a portion of the back mounting surface for the plug receptacle to pass through. I still have to polish the casting face and paint the detail strips in, before I use sealant to glue the LED lights to the casting
Hi Kip, I did the same thing last summer and posted some pics. Andy from Inland RV had a reply that left me with the impression that he has them. I sure am enjoying your posts. Thanks, Bill
