Overhead Lighting Brackets
I added brackets for some gooseneck map lights. The .032 sheet was bent with a .25" flange for stiffness leaving 1.25" width for mounting. Fabbed the brackets, prepped the area, welded, and sprayed some crc sp-400 corrosion protector.
Ventral Fin Stand-Off
I added a fitting for a ventral fin which may be necessary to add vertical area to the plane if placed on floats. The need for a ventral fin is dictated by engine/propellor selection (power) and the profile of the floats in the water. I measured, drafted a pattern, fabricated the part, welded, and sprayed corrosion protection today. The stand-off is made of .063 4130 steel.
Floor Fairlead Cutouts
This evening I cut the cargo area floor panel to fit around the rudder cable fairleads I added. I also sanded some filler I added to the trim tab cut-out tubes. I didn't wait until the epoxy set up enough for the previous round of filler so I had to add to it to make the filled area flush.
Trim Tab Cutouts
This evening I worked on grinding the cut tubing areas flush on the trim tab cutouts. I also worked on removing welding scale from within the trim tab hinges.
Prepped parts for welding, Welded additional fairleads, Rudder fabric attachment
Today I prepared tubing for welding by using my die grinder and scotchbrite roloc wheels to remove the Avipro paint and primer. In some smaller areas I had to use a small detail wheel on a dremel tool. Today I successfully added fairleads at STA E and a fabric attach channel on the lower rudder hinge. The fairleads were added to prevent the rudder cables from rubbing on the back seat as covered in a previous post. The channel I added to the rudder is to provide a place to attach the fabric on the bottom of the rudder since there is a hinge there and not much stationary area to glue to. The rudder fabric channel was bent from .032 4130 and the fairleads are .058 x 7/8 tubing (3/4 long).
Bent T25 ribs and Rudder fabric attach channel
I bent up 2 additional T25 ribs that I intend to weld in place to help retain the counterweight. I don't like the idea of screwing through the structure per the instructions so this is an alternative shown in the scratch builder guides. I also bent up a channel to be welded between the rudder horn and the lowermost tube to provide a fabric attachment location. .032 4130 was used.
3 Month Progress Update
I've been forgetting to take pictures of the project, and when I do, the editing and posting process has fallen to the back burner. Here's a look at the fuselage. You can see I still have a little trimming to do on the floor inspection panel.
Began Fabricating Floor Inspection Covers
I started on the fabrication of inspection covers for the floor area around the control sticks and flap handle. There are many cutouts to size and fit, so I'm only about half done with the covers now. It's pretty challenging to get something that will slip into place without removing the flap handle or sticks and still seal up tight to the tubing and fittings in the area. I've already ruined one cover and had to start over.
Made Templates for floor Inspection Panels
I used poster-board to create templates for some inspection covers that go under the flap handle and over the shock struts.
Deburred Custom Floor Panels
I used a scotchbrite grinder wheel and fine emery cloth to debur the edges of all custom floorboards.
