Place a weight on top of the sheet to keep it firmly pressed against the spacer board. Take the aluminum angle stock and while pressing against the table top and sheet stock, slide it back and forth a few times until you get a nice edge.

The results should be seamless!

Here's a good shot of how each rib's cradle keeps the stabilizer level to the work table during construction. These tabs will be removed once I flip the stab over.

I'm very pleased with the full contact that I got between each rib and the top sheet.

Top sheeting of the stabilizer has been completed. At this point the elevator is still attached to the stab and will be sawn off once the bottom is completed.

With the stab flipped over I made quick work removing all of the tabs.

You can see looking at the stabilizer's Leading Edge it has tapered ribs. All of excess material will need to be removed without changing the profile of each rib.

I used a small block plane to go as far as I dare, time now for the sanding bar. Sanding has to be done very carefully so as not to snap off any ribs!

I try to span the entire width if I can. These are my sanding bars.

Before calling it a day, I decided to epoxy these elevator torque rod blocks (4 per side) in place.

Our fiberglass parts came in today! I've used Fiberglass Specialties on a number of planes that I have built, but I have to say these are the nicest parts that I have received from them to date!

Plans show three hinges per elevator, but I will be installing four per elevator. I will be using 1/8" Robart steel point hinges. You can see the locations on the plans as I have highlighted the areas.

Using steel point hinges require structure to anchor into so balsa hinge blocks were added in the appropriate locations. You may wonder why the hinge blocks run the full span between rib bays when a one inch block wold suffice. If while drilling the hinge a mistake was made, I can easily just move the hinge location over without any trouble...

One detail that I would like to point out. If you look closely at the trailing edge of the elevator, you will notice how the top sheeting has been beveled slightly. This will allow the bottom sheet to mate correctly with the top sheeting.

With all of the internal structure completed, I'm now ready to sheet the bottom half.

Beveling the top sheet will create a gluing problem if your not careful. I know that if I ran a bead a water based glue such as Titebond II along the thin trailing edge it would more than likely warp. To solve this problem I spread a thin layer of epoxy along the edge thus preventing warping and the epoxy will stiffen the thin edge of the elevator. The rest of the glue-up Titebond II was used.

Now is the time to liberate the elevators from the stabilizer. My preferred tool to use is an old blade from one of my Zona saws.

The trailing edges came out perfectly straight, and the epoxy has stiffened up the end considerably.

Before I forgot, I labeled the positions of the elevator in relation to the stab.

Trailing edge of the stab is sanded flush and readied for a final 1/8" thick cap strip.
