Paper Jet continues




The dry fit of top and sides to determine inside out side of panels and the start of lay out. And yes a little excitment that it is ready for the top to go down.
The lay out and gluing of the wing. Dry fit the top lay out mast frame before gluing things together and down. The exterior of that crazy 45 deg corner turned out ok.
Interior of that crazy 45deg corner that was described in the last post. With some sanding and tlc this turned out ok. The material for mast getting scarfed together. Sides and top getting epoxied on the interior.

Here it a trial run on 2foot of scrap the boom is just a tick longer than 8foot so I used 10' boards then used the scrap to do a trial run, 8 foot was real treat. Here is my completed boom. The detail about how this is done is down on the mast pics. Had struggles on my first 8' run but it turned out ok. Little disapointed in the fact it did not turn out straight. Hope it does not show in the wind! Putting four years of college books to good use and a couple of atv straps to help make sure the top makes good contact with frames as epoxy sets. To much? maybe better off doing it right the first time.
Still can not see much here a total of 35 zip ties one for every 6 inches. The proses went really well even by my self. Had everything laid out where the cores went on the interior, the epoxy was all premeasured out in the utility room ready to mix and go. Used quarter quart zip lock style bags for fillet tool turned it wrong side out then once the epoxy was mixed gather as much as I could on the stick and push the corner of the bag back in as I emptied the 3oz of epoxy mix and a scrach awe to open the corner. Lay a bead in the V notch of the birds mouth smoth with finger before fliping over and the finally placing in the U shaped forms. By the way 3oz works perfect for 16 foot. Here it is official 18' of mast all ziped together. Only 16' is needed stager the scarf joints to get the most strength posible. Completed on Feb 28 at 28 degrees and sunny.
