Windows and Plumbing

Starting to work on a lot of the small finishing projects on the fuselage.  A small piece of 0.060 Lexan was cut from the sheet that will be used for the doors.  Two triangles were cut using the templates provided by a fellow local Highlander builder,  A vibrating multitool was used to cut the shape and then the edges were polished with sandpaper.  Using the holes in the fuselage window opening, the mounting holes were drilled and a cleco was installed.  The holes will be upsized later for 1/8" aluminum rivets and the holes in the Lexan will be oversized to allow for expansion.

Work has started on the brakes as well.  The current plan is to use the provided nylon brake line up to the Grove landing gear.  The plan also includes using stainless-steel braided teflon hose from the gear to the brake caliper.  Fittings were added the brake master and slave cylinders.  Nylon hose was installed between the master and Slave cylinder.  We ordered a Matco parking brake valve from Aircraft spruce.  Two holes were drilled under the seats that will allow the brake lines to connect to the Grove gear. Grommets were installed into the holes and two runs of the nylon hose were passed through and conected to the fittings in the gear.

The Rotax fuel pump needed to be moved from its previously installed location.  Due to fuel line hose constraints, the  fuel pump needed to be moved about 2 inches or so further away from the Andair gascolator.  A new mounting bracket had to be made.  Actually the new bracket came out much nicer than the first version.
