[Jason Murphy]

I have decided to add my build log to the Kitfox Forums in addition to the EAA Builders Log to receive feedback from members of the forum.

Prepped and installed drag anti drag brackets between ribs 3 - 7.

Located and bonded ribs 3, 4, & 5 to wing spar. Secured with clamps and applied fillet of hysol.

Plan for next work session is to locate and bond ribs 6 & 7 in place. Waiting on drag anti drag bracket to arrive from kitfox.

Ordered plain aluminum hubcaps for grove wheels. Will polish to match landing gear.

Sanded ends of horizontal stabilizer and elevator to match. Applied additional Superfil to end caps due to removing too much material initially. Obtained a pleasing contour at the junction of the elevator and horizontal stabilizer.

Added superfil to inside of the end ribs to prevent moisture from becoming trapped inside.

Prepped spars and bonded false ribs with Hysol.

Filled air bubbles in SuperFil with remaining hysol.

Bond and Rivet Lift Strut Brackets. This job is a mess.

Made relief cuts for spar attach brackets in No.1 rib.

Dry fit left fuel tank.

Received previously loved propeller from a friend and fellow Kitfox owner.

Alex, it would have been a privilege to polish that up.

Fitted Top False Ribs between rib bays 3,4, and 5. Each false rib numbered for reassembly after the spar has been prepped.

Hi Jason,

Making good progress!

Regarding the air bubbles showing through - in my experience with car finishing and airplane covering, it is worth considering that any irregularity under the fabric/paint will show up much better after the job is done - by then it is a little difficult to put the eggs back in the shell; but, depends on if a person is concerned with that or not - on a utility finish it probably doesn't matter - it will fly either way.
