Build Log

a6m Zero build for the PSS Fest


Debating between making this into a plug and doing a mold or going with lost foam? I am leaning towards lost foam as I keep finding too many mistakes on this thing. Next time I will be using wood for sure!!! Still have some detail work regardless which way I chose. Boy have I learned alot doing my first scratch built glass plane. I took it over to Doug Blackburns house (Twinboom) and he thinks I should make a plug and mold. What do you guys think? Any interest any a zero??? All observances and criticisms are welcome...and yes I know the fins not square

Got the wings done tonight so I had to take her for a bench flight. she comes in at a 45 inch wingspan.

I like it Dave. Could always use another warbird out there. If you decide to mold one I'd like to see it on the bigger side...60"+.

Isn't that blue foam fun?

Ugh, I can certainly relate to the frustration of working with a foam plug. I'm doing a Macchi Folgore, 63" WS and I finally said to myself "F*** it, who cares what it looks like! Just fly it!" I got sick of trying to fix all the dings, dents, finger indentations, warps, etc etc etc.
I figure that for a first attempt at mold-making, I'll just chalk it all up to being good practice. I've learned a LOT, and look forward to making my next plug out of wood. Hopefully my camo color scheme will mask most of the surface imperfections.

I'd be interested in that fuse I'd love to have a 45" Zero. Great looking work Dave.

There's something about the name Dave and gliders . . . .

Well I took her to the ISR meeting and found out everything that was wrong with it...Thanks TFLG

It was cool to get everyones input at the meeting and then to come back and give it a shot for the first time.

Came home and fixed some of the issues and today I glassed her fast and dirty as Artsloper (Ralph Roberts) would say. This is Ralphs method that he taught me last night. .

1. Tape
2. 77spray
3. Glass
4. 77 spray
5. Glass
6. 77spray
7. Glass
8. Pantyhose twisted tight to hold everything in place. This works awesome!
9. Polyester Resin with a mask and REALLY good ventilation.

Next will be the BONDO marathon after she drys for two days. Blue buggars here we come!

Here are the steps in photos

Hmm,,

This looks a little small to be chasing my Dauntless ....

Looks like your diving in and fixing up some of those issues that I saw at the meeting last night.

Good Job Dave

Dan I did 4oz and 10oz on the whole thing and one more layer of 4 oz in the front of the wing saddle on the sides. Is this enough or should I do a layer of .75 oz before I bondo to smooth things up or just start bondoing now???

It seems SOOOOO rough right now?

Do I wait 2 days before sanding??

Thanks

so I let it dry overnite and sounded out some of the really rough spots and then had to add a little glass here and there where it was a bit thin.

It sure looks like it is going to take a ton of bondo!!!

Dave, all the stuff Joe and I are doing we used two layers of 9oz and the last thing you waht to do is sand it down to the foam. Bondo can cover up a lot of ugly but has no strength so be carfull.

Take it from one who knows.
