Ken,
How did you handle the aileron's, did you cover them before adding the panels of just seal the wood? I was thinking about just covering the L/E and then seal the wood and glue the panels on. Also what glue did you use to glue them on?
Later!!
Anthony

I covered the leading edge with polyester overlapping the top and bottom surfaces about 1/4". Same with the inboard end. On the trailing edge I cut a strip about 5/8" wide and tacked it to the top and bottom surface at the inboard end. While pulling it tight along the trailing edge I ironed it down alternating from one side to another. The strip was folded as I did this. This left a sizable area of bare wood on both sides. I put a couple of coats of Polycrylic on the full aileron.

A paper pattern was made before I cut out the corrugated plastic. I used a new single edge blade to cut the traced pencil marks on the back side of the plastic. Of course I had to make cutouts in the plastic for the horn and inter-aileron link.

When I was satisfied with the plastic fit, I used some small clamps to hold it on the aileron. Then I lifted one end of the plastic and applied medium CA to the aileron on the inboard end for about 4" of it's length. Just a simple overlapping S pattern was used. After laying the plastic down I was able to remove the clamps and complete the process in 4" lengths.

Several pages back I showed how to extend the length of the corrugated plastic.

Status: offline 		I was able to get a decent pic of the rib stitching by turning off the flash and holding it in the light just right. I think once it is covered with the rib tape and everyting is blended in with a coats of PolyC it should have the correct subtle look of the full scale. I have the bottom wing rib stitching complete.

Status: offline 		Guys,

Thanks for the collective wisdom. I'm going to fix the incidence error. Just eyeballing, maybe 6 inches from wing joiner to dowel. If off by one degree...6 TAN 1 degree equals abourt 0.100 inch. If I relocate the dowel hole and make sure the joiner doesn't prevent rotation (and put a minor twist into it if it does), it's taken care of. Better now than to wonder why it climbs so funny later.

Here is a photo of my grandson Nicholas. He's my chief helper.

Status: offline 		Very nice,
The Waco is looking good and it looks like you have some fine help there. I just became a grandpa 7 months ago and I am already enjoying spoiling the little fella.
Here is a pic of my grandson, don't think I will let him get close to my Waco for a few years Poor little guy is teething and a bit fussy but he will still smile for grandpa.

Status: online 		I bought this at Lowes today for sanding primer. So far, it is the best that I've used. No clog and easily shakes out. It's a bit pricey ($8 for 2 pads) but seems to be well worth it. I'll let you know how it is for longevity.

Status: online 		Anthony, I'm getting ready to carve the head rest fairing that goes back to the vertical stab. By the way, what is that thing called?

What I need to know is how wide it is at the headrest and how tall it is there. Did you glue yours on before covering? Here is a photo of the stab fin. It doesn't look quiet right to me. How would you modify it?

The fake stitching sure looked good.

Status: offline 		Ken, I think it would be the turtledeck, maybe. I am going to terminate the rear end of the turtledeck with the leading edge of the vertical fin and blend them together. I think this is how it's done. Anthony may have other ideas.
Also, I think I have the correct dimensions of the headrest at home if you need them. John provided the full scale dimensions somewhere on the other thread and I just divided it by four.

Status: online 		Scott you may be right. I usually think of the turtle deck as larger and more rounded. I need the dimensions. I also need to re-sculpt the front of the vertical stab and recover part of it. Any help is appreciated.
