Horizontal Stabilizer

Here is my second attempt at filling the HS with foam. (No pictures of the first) After the Trymer 2000 foam glued in with a hot glue gun failed, I filled the HS with Great Stuff spray in foam. It left large voids and stayed somewhat soft. I spent a day on this second fiasco. I ripped it out and started again. This time with the Dow Blue extruded foam.

Now that I think of it the Trymer would have worked with the spray foam as the glue. The spray foam will stick to anything so be forewarned wear latex gloves and old clothes.

This picture looks a little better for the third time filling with the Dow foam. I left the spray foam in the hinge area. The hinges were wrapped with duct tape to keep the spray foam from adhering to them. This was my next mistake.

I covered the HS with two layers of 6 oz fiberglass using Aeropoxy. As the epoxy cured the heat generated made the foam expand a little more leaving a hump over the hinge area. Drats!

I sanded off the hump and applied some more fiberglass to patch it. Problem fixed. The elevator was cut off with a Rotozip tool with a zipmate attachment and metal cutting blade. Worked great.
