[simpits-tech] MacGayver

[Marc Weigert]

Hey MacGyer (Fred) ;o)

Thanks alot for that thorough explanation!!!

When using these foam panels the way you descibe it
(putting them BETWEEN the ribs), I won't have fitting
problems remove them, as I would have when I put them
on top of the ribs - that's great!!!

Would you see this method to work also with this (click the link)
structure??

I'm asking as I won't fancy to sandpaper and glue the metal frame's
ribs too much ;o)))

As for what concerns MacGyver: I'm sure I would have had 30% better
marks in school, if they wouldn't have repeated them twice a day the
months before my final examns! Thought watching it is best preparation
for my physics examns but was prooven to be totally wrong with that
assumption! ;o))

Cheers & good night,

Murdoc ehhh no... your grandfather Harry... or am I Pete Thornton???




FM> 	Ok, you asked for it, now I will slip into my MacGyver mode. If you do not
FM> remember the series, MacGyver work for a group and was always taking odd
FM> objects to solve problems or get away from the bad guys. My wife claims I
FM> am like him!

FM> 	If you are making a fighter aircraft (who is not?), you will have compound
FM> convex curves, curves in more than one direction and bowing out.

FM> 	The nylon net will not work unless you have a lot of support for the curving.

FM> 	The way I would do it is use the foam panels that are used in home built
FM> aircraft. You do not have to use the thick ones as
FM> there will be no external forces being applied. Cut the panels to fit
FM> between the ribs with excess protruding to the exterior. Glue the
FM> panels in place with something that will not attack the foam.

FM> 	Rough cut the foam to the approximate curves of the outer skin and flush
FM> with the ribs. Now use sandpaper on a block to smooth the curves to the
FM> proper profile. You now have a backing for fiberglass layup.

FM> 	From here, I would get a book from one of the aircraft homebuilder sites
FM> to take you through the proper use of resin and fiberglass. A finished skin
FM> can be sanded smooth as you wish. Really get adventurous and drill small
FM> holes and get some rivets from Ebay and resin them in before painting!
