After gluing styrodur, we sanded it into the round shape. that was done in less than 15  minutes.

Preparing for gluing the box in which the engine box will hang (you could see it on my previous reports).

The next campaign was mast lamination. I will have two A masts and we started with shorter one. Good because i cuted the unidirectional fiber just as wide as it is the circumference of the mast.  

Both masts under vacuum

Finished masts.

We are wetting out all the fibers on the table, and then we lay them on the beam.

On the corners i used also carbon (750 g/m2), i was planing to do both sides at ones, but it was imposible. You can see why on the video.

We lat it dry out, and than we did in the afternoon the other side. Without vacuum that would be imposibile.

On the 2nd of June we were laminating the third beam, here are some pictures of finished beam, I have no pictures of lamination process.

Bare styrodur glued together:

I aded a part of styrodur, and one will follow on the other side.
Beam is 19 cm wide, It has a 4 cm thick T, and on the other side will be 2 cm thick.
