Composite mast Layup Video
ROBERT RAST:
News from area 51 (Smokestacks Basement) Hey Eric Wilson (Eman) smuggled this video out with out us knowing its a experimental mast layup , the new Viagra model Fat Bastard for Skippers with a little extra Ballast
Any way the news is out

How long does it stay stiff?????? What happens if you blow it out????? Does the cold air affect it?????
ROBERT RAST:
The epoxy i use is warm weather 80 degree the basement temp is about 65 so you could work for hours putting it in the mold. The glass and carbon go into bottom half of the mold and the bag is placed inside ,the edges of the glass carbon are folded over each other creating a overlap on the front of the mast. After the top half, front of mast is secured I add 20 lbs of air to push the glass to mold. Then we place a foam box over mold and apply heat using a small electric heater which brings temperature up to 140 to 160 degrees in the foam box eventualy soaking through the mold making epoxy kick off, after about 10 hours at his temp it is cured the mast removed and reheated to maximize cure of the epoxy.

Robert thanks for the video. Do you or anyone else out there have suggestions as to general layup schedules, either previously published anywhere or would you be willing to share some successful layups? This for people who would like to try building a composite mast but are nervous about using expensive materials and time on a total trial and error exercise. I've got a couple of old masts to use for building molds. Any opinions on whether the Kenyon or Norton wing shape would be better for a composite mast. Also I've been intrigued about the Bamboo based mast. Does anyone know where the bamboo veneer can be purchased? I've read in here that the time would better be spent on runners but the mast sure seems like it would be fun. Thanks Steve Ryan, DN 3674
