Repairing a new glass fuselage
Hi,
I just got a really old Jet Hangar Hobbies kit partially assembled and have a question for you guys:
There are a couple of broken parts/"slits" in some parts of the fuselage, how can I repair these? Should I just glass the inside and use filler on the outside. The fuse is new... I do want to get this one in the air sometime this summer.
What kind of cloth should I use 1/2 oz. or 3/4? Although I saw somewhere to use 2 oz. can this be?
Thanks and any additional input will be greatly appreciated.
Kind regards,
Homero Cuellar

RE: Repairing a new glass fuselage
3/4 oz cloth is too light for repairs. Depending on the size of the damage 2 oz would be the minimum, for big holes up to 6oz is suitable.
clean up the inside of the fuselage with acetone,sand the area to be repaired and lay the cloth over the damage, brush on the resin. Fill the outside with resin/microballoons and blend with the rest of the fuselage.
If the fuselage is epoxy use only epoxy. If the fuselage is polyester epoxy can be used but polyester is preferable.

RE: Repairing a new glass fuselage
Agreeing with Ed (again)...
The fuselage was probably built to about an "8" or "10" (i.e. 2 layers of 4 oz. cloth, or one layer of 2 oz. cloth and a layer of 6 oz. cloth... whatever) So, I'd use repair materials that more or less match. Since it's on the inside anyway, the "bump" won't be important.
Bob Fiorenze, in his article regarding the repair of his severely damaged F-14, recommended tacking everything together (aligned!) with thin CA, sanding the interior and exterior, then proceeding with the repair. (It was severely damaged, in a mid-air.)
