Looking good! You may want to experiment with using micro balloons to fill the weave of the fiberglass so that you don't add a bunch of weight in primer. Basically, when the resin is tacky dump micro balloons on the surface and spread them around carefully by hand, working them in to the weave, but being careful not to disturb the glass. The excess micro balloons will obviously not stick to the airframe, and can be scooped up and re-used. If you'd like a more in-depth tutorial, I can dig one up for you.Aryana wrote:I've come this far and now I'm really trying to make sure I don't blow it at the end and keep the cosmetic quality of this airplane as high as possible.
I've never done fiberglass over balsa, so I have a lot of apprehension about screwing up all my 400 hours of work with a bunch of resin and cloth that doesn't come out as I envisioned.
So I trsted a few scraps and decided to dive in. I am using 3/4 oz fiberglass cloth with thin finishing resin. Sanding with 220 grit in between coats, I thought it prudent to start with a low risk piece first to see how this goes, so I grabbed the hatch cover for the radio gear in the wing center section.
Grow your beard out a little bit and I doubt they'd think twice. Either that or get some feminine hygiene products to soak up the excess resin when you buy a case of hair spray.Aryana wrote:I had no idea you could do this! Think they'll give funny looks to the bald guy buying hair spray at the check stand?Ryan Smith wrote:Also, are you sealing the balsa before you glass it? You're not using contest balsa, so it's not going to be nearly as porous, but try using some cheap hair spray (like Aqua Net) before you start glassing so that the wood doesn't soak up too much resin. You'll inevitably want a nice finish, and I'm sure you'll want panel lines so you'll be adding a lot of primer as it is to get those.

If you had to estimate, what would be your guess on the number of visible rivets on a 170B? I'll eventually know the real answer when I transfer them all to the scale model, but people keep asking me and I don't have a very good guess.
Wow!Aryana wrote:Whoever is closest will get a surprise item from my collection of 170 literature...it will be a original 170 brochure, advertisement, or postcard!
Just post your guess in this thread and we'll see where it ends up!

... GREAT work and fun to see!)Funny how the last 10% always take 90% of the time. Quality requires persistence and persistence requires time.Aryana wrote:Good think there isn't a time limit on these sorts of things! The last 10% is taking longer than I had hoped. More progress will follow and I need to get to the rivet phase since that will take awhile.
