Maybe the Prandall?
This evening the epoxy went off very quickly because of the heat. We mixed up some micro balloons, fumed silica and epoxy resin with a drill motor and paint mixer till we got something a little thicker than peanut butter. We then squeegeed it on the taped joints. It is the equivalent of high performance body putty. After this hardens enough, maybe tomorrow, I will start sanding and smoothing to get it ready to cover the entire hull with the synthetic woven material, the Dynel on Weds night. Micky and Jeffrey were here and we got quite a bit accomplished in a short period of time.
We also mixed up some faster setting epoxy and glued three sheets of marine ply together to make the skeg that Hno. Astorga cut for us. We glued them together and then screwed them with some stainless screws until the epoxy hardens. We will then pull the srews out and the holes will be puttied later. The skeg gets laminated aft on the hull. We'll sheath the hull before the skeg goes on. A bunch more putty will make a nice transition with the skeg to the hull. The microballoons make it easier to sand and they assure the putty will be lighter than water, so it adds to the buoyancy. This is all of the structural work on the external seams. Next Weds night we will have the entire hull covered with the Dynel. After that, we will paint several coats of epoxy on to the Dynel and then we can paint it. The boys want red and white and red and white and green. The various national colors for Peru and Mexico respectively. Maybe we will name the boat the 'Prandall', after our friend Paul Randall. We all miss him. There is a fast sailing catamaran named the Prindle so the Prandall sounds like it could be the name of a fine boat.

More work on the boat...
Miky and I made some great progress with the boat today. Besides doing a dry fit up of the outboard motor mount on the transom and thereby determining we need the long shaft 4 hp Yamaha, we also taped all of the exterior joints with a 12 oz. special bi-axial fiberglass cloth. You cannot see the joints because the glass becomes very clear once the epoxy resin wets it out. We will mix up some epoxy body putty tomorrow and 'fair' all of the joints we taped. Then on Weds we will cover the entire exterior hull with a synthetic glass material called Dynel. It is also woven and tougher against abrasion than fiberglass. Some of you will be attending Trek but the rest of us will work on the boat at 7:00 PM at my house.
All of you will need to do some serious portions of the fiberglass work for the composite materials merit badge. We will have opportunities on the exterior and later in the interior as well.

Another few hours on the dory
We have completed the exterior sanding and fairing of the hull and are shaping the skeg and keel. The next step will be to tape the seams and glass the entire hull. Keep in mind this is in lieu of covering a cardboard box with fiberglass to make a bird house for our composite materials merit badge. Once we have the hull encapsulated and properly reinforced then we will install the skeg.
Thanks to Javier for fitting the skeg so carefully.
We still need a name for it and have to decide on the colors.

Trilobite Hunting in the West Desert
We arrived at the dig Saturday morning after a great breakfast of pancakes, eggs and sausage. Friday night we had buffalo burgers on the grill and a moving message around the campfire by Brother Olivera from Alma 30 -- the evidences or signs for the existence of God. A trip into Utah's back country and to gaze into the skies on a clear night confirms to me the beauty of God's creations.
The trilobite hunt was successful and Pablo claims to have found the largest of any that day in the quarry. That may have to be resolved by a side by side comparison. We did find some large trilobites and I think nearly everyone found their ten fossils for the geology merit badge.
We appreciate the fathers and leaders who went with us and helped make the trip possible. Special thanks to Brother Dennis Vest, Martin Gonzales, John Olivera, Pablo Ramos and our Branch President, Jorge Orozco.
