Re: Fuel Tanks
James Doyle <jdoyle1941@...>
Guys, When I built my Q I sanded the entire area where the tank was to be and put one layer of "B" glass on extending 1 inch beyond the tank and saturated it with safetypoxy. If the tank top is sealed with a liberal amount of epoxy and bedded well in flox. IT WILL NOT leak. I had 900+ hours with no leaks and I used auto fuel when ever possible. Sam is right, follow the plans.

Sent: Wednesday, September 13, 2006 7:30 AM Subject: RE: [Q-LIST] Fuel Tanks I recall hearing that Rutan and the EZ guys went to the very light fiberglass cloth like they use on RC models to give the extra epoxy coats on the inside of the tank some structure and to reduce the number of pin holes. Perhaps Terry Crouch can comment on this or some of the other guys familiar with the EZ's.

Subject: RE: [Q-LIST] Fuel Tanks An aluminum tank makes absolutely no sense to me. What problem are you trying to fix? Everything is there in the plans to get it right. To keep the tank from developing pinhole leaks, paint on a couple extra coats of epoxy, it's no big deal. Geez - where do these wacky ideas come from?

Damian Gregory also recommends a bladder.
