I agree about the perfectly smoot surface not looking right. On a lot of models, the addition of riveting detail can help mask it. The problem with the Corsair is that there are not all that many rivets because the bulk of the skin was spot welded. Getting the subtle wavey look of skin applied over ribs, stringers and bulkheads is probably beyond my abilities, but I sure would like to come across a technique for it.


This is an interesting topic and is something that I've been wanting to try for some time. The plastic model guys have come up with a way of replicating the stressed skin look on metal aircraft as can be seen on the A-20 Havoc model pictured below. The link is to a short tutorial on how the plastic guys do it. I think something similar could be done to the surface of the balsa prior to fiberglassing to achieve the same results. I plan to make up a test wing sample at some point and just try it to see if it can be made to work. It would take considerable effort but would certainly be worth it if it worked.

If it works out, the idea of bending the yoke out of brass is a keeper. That is one of the most fiddly parts on the Aune build. What thickness brass did you use?

Status: offline 		I like the stressed skin tutorial above. Interesting food for thought and experimentation. I always come back to Dave Platt when it comes to surface detailing as he seems to have a pretty good idea of what looks right. Tom Pierce did a really nice tutorial here on building up cloth covered panels using Dave's method - http://www.tompierce.net/190/html/paint/ctrl_surf_details.htm

I used .025 brass. It bends quite readily. The axle and microballoons really help to stiffen the yoke. The axle is a .85" long piece of 5/16" tubing that has two washers soldered to one side, and a removeable 1/16" thick spacer made from 3/16" tubing on the other side. It is assembled with a 1" 4-40 socket head bolt and nut. The wheel is a 2 1/4" Dubro foam wheel. Later, I may try my hand at casting a more realistic wheel.

Status: offline 		Great work Scott. Glad you're in on this. Just got my Aune gear, and had a little "thank you" chat. Nice guy, and quality product (very nice looking). To add drag links with it is darn near impossible though, as I look at it. I guess there will be compromises. Richard had a guy, Buzz, that came up with something workable on the links. I would like to here on that. Until then.. thanks Earl!!!! -Eric

p.s. I think the Earl Aune gear is generally superior, so don't hesitate.

Status: offline 		I had a really nice surprise today as I was driving around So. Cal with my wife and discovered the CAF Museum at Camarillo CA. A nice collection of flyable warbirds including and F6F, and F8F, an A6M-3 Zero, a Yak 3 and a number of others. Nothing relevant to this build, but I'll post some photos on my site when I get home. Nice folks there too.

p.s. keep it up gang!

Status: offline 		Great Tom, way to work it. I have looked at Harbor Freight. Good stuff at a nice price. I will buy their little disc sander. I see a reasonable lathe for 150 bucks with stand. Nice. I couldn't be sure on terms, technically, on what I could turn on that cheep wood lathe. I think it would be good for the cowl, and then I'd rarely use it. I am not sure it was big enough for a cowl though. Can we get specs in common language (non-machinist), on tool requirement there (turning part diameter)? I saw all the other metal turning equipment...super..I need a metal class (above my welding and stuff)!


This is part of our longer term plan I know, but the cowl must get done absolutely right, or we are not getting anywhere. The cowl is amongst the worst parts out there from everyone. We should demand the best on this at least as good as the best plastic model (that industry seems to get it right mostly).[)]

Luke did have a good one. I just don't see it offered, so we are going to have to bust some knuckles!

Status: offline 		I've been eyeing one of their metal lathes for some time. I'm close to giving in. I may and try and catch the next time it goes on sale.

They had a wood lathe on sale for under 100, but it looked too small for turning the cowl. I remeber seeing somewhere where a guy used his drill press as a poor man's lathe for turning a foam cowl plug with good results.
