…but building has slowed as I am waiting for my Steen Aero Wing Kit. It was ordered in July and still waiting. Was hoping to get it before Christmas, but still hasn’t been completed. I am told its the laminated spars that are holding things up. It may be because they are building the delta spar mod and my guess is this may be the first time they have done it.
In the mean time I am trying to find little things to do. I have ordered the components for the upper wing fuel tank and will start on that if it doesnt arrive soon.
From the last post I was making up the rear handrail that runs along the rear of the top wing centre section. In this post you will see the fitting of the rail to the rear section. It required trimming the hand rail itself and sanding the profile into the trailing ribs from the rear spar. I can see that the gap here particularly in the outboard bays will, once some supporting blocking is added will need to be filled with foam and glassed to get a smooth solid surface for the fabric to stick to. Of course that will be later as I won’t be doing any more to this section now until it is trial fitted to the fuselage.
In the photos above you will also notice that I have trimmed and prepared the bottom section of plywood. This will provide structure for the “box” that is the centre section. In addition it will contain the large (relative to the standard Skybolt) upper fuel tank.
The piece of timber laying on top (though the centre section is on the bench upside down) is the first of three laminated stringers that run front to back and screw into the spar. This will provide further strength to the front leading edge, centre section bottom ply and add rigidity to the complete centre section.

I remember reading on some build posts about the need for a large number of clamps. I have found myself drawing the same conclusion. I find every time I walk into a hardware store I pick up a couple of clamps of differing kinds as the use of them changes.
I can confirm, if you are building a wooden plane – they are your best friend. I must also say you get very adept at putting them on even with one hand.
Below is some pictures of the laminating process for the hand hold that sits at the rear of the top wing centre section. Most of this will be covered eventually except the middle which will assist the passenger in the front pit extracting themselves on the way out.
