it is 3mm thick. Depending on the outcome of this part, I may go down to 1.5 or 2mm later on.

The airex is used b/c of its High strength properties and low weight. all of the pieces in the one stab probably weights 2oz

Looking great, love the cheaper materials/alternatives to actual composite supplies.

Watching your video I was wondering why you didn't use a perforated barrier sheet between the part and the batting/bleeder layer. What do you do with the batting after the part cures? Does it peel away from the part ok?

Thanks,

Chris

the layer between the bleeder and actual part is peel-ply. When ever you use peel-ply it peels right off typically. The only time you really need a perforated sheet, is if your not looking for a ready to bond surface (the peel ply makes it where no sanding is needed prior to bonding). The perforated sheet then takes the place of the peel-ply.

In between feeling like Crap today (i think i'm getting more sick), and getting home from work, I did some work today..

Trimmed the flanges on the top of the fuselage:


Flipped the fuselage... HOLY crap this thing has gotten heavy. Its easily 150lbs right now:


Then put some body filler on the aft end of the fuselage that needs finished:


then the stab mold halves came out of the vacuum bag and the peel ply and bleeder cloth pulled off. Next time, i'll probably go with 2 layers of peel-ply, or just be a little more cautious with the resin, as the peel ply was a pain to get off on one half (see video):

If someone approached me interested in doing so, I would entertain the offer. I have over 30 GIGS of information on this build, and still have ALLOT more to go.

Made up the internal structure for the horizontal stab and closed the stab mold last night. the internal structure consist of a solid carbon "rib" with a hole for the tip of the stab pivot rod and a slot for the titanium anti-pivot rod to slot into. The carbon rib then has another piece of carbon glued to the tip side of the rib to keep the anti-pivot rod from coming out. Then 2 pieces of sold carbon are glued parallel to the stab pivot rod. Then a 3/16" spar is run from the carbon rib parallel to the stab LE to about 2" shy of the stab tip.


Yesterday afternoon i made up the majority of the lower fuselage parting planes for 3 sections of the bottom of the fuselage:





Then this afternoon, I waxed the planed off sections to prep them for molding. Then i opened up the horizontal stab mold, and cleaned the flashing off the part.



A Few things were learned.
1. Its HEAVY @ 1.5lb (.3lbs of it is titanium parts).
2. It is WAYYYYY over-built.
3. The 3mm airex can be replaced with 1.5mm airex
4. A full-carbon skin isn't really necessary.

The fuselage mold is definitely one complicated piece... I just hope when it comes time to take it all apart it breaks down like I want it to. lol

WOW!
I'm still wondering how you're going to actually make the fuselage part. It surely won't be possible to do it as one piece, so will it be done as a single top and bottom piece?
One other thought is, how on earth are you going to get the mold that goes down between the fuselage and the intake off?

The fuselage will be molded in 4 different sections. 1. Top, 2. Bottom, 3. Left inlet ramp, 4. right inlet ramp. Then all joined together.

The plug was constructed so as not to lock the mold into place between the fuselage and inlet ramp...
