Covering the cabanes

I thought it was worth while remembering how to cover by starting on something with little aerodynamic risk ... the cabanes were the ticket, as opposed to the remaining aileron or the wings themselves.

I'm using the Stewart Systems process, which starts with cleaning all the surfaces with alcohol, using cloth tape to cover any sharp edges or corners (like the bolt heads), and then applying a layer of glue to dry.

This is one of the cabanes after cleaning and after edge taping.


From my old material cut-list, instead of using a single piece of material over the whole cabane, which would leave a lot of wasted material, I decided to cover the front and back triangles separately.  Practically, this meant a weird seam at the junction of the fore and aft triangles, but I'm okay with that since these pieces are structural but not really aerodynamic.

Here's the back triangle covered, mid-trimming of material from the second side overlapping onto the second.

Finally, the forward triangles were covered in just the same way, with an overlapping seam to join to the back half.  This covering job took place basically all day on July 4th, so it wasn't really that terrible amount of work.  There is definitely some time spent waiting for the adhesive to dry, but most time is spent pulling out wrinkles around corners or areas with bolts.  Here are the final products.


I will say, I got better even on the second cabane after completing the first.  It also was WAY cleaner to let the adhesive dry completely, rather than trying to use a heat iron into wet glue.

Onward to finish covering the aileron, which is the last small part, leaving just the two wing panels remaining (and probably three dozen reinforcement patches on all of the smaller parts).
