1) tacked the rudder stops at the tail into place and then flocked
them... the should be just inside 98mm to allow for some wear and
tear/sanding down
2) refitted the back seat backrest and flocked it into place as
instruced with self tapping screws..
3) flocked and glassed the vhf bottom antena
11/26/2005 4:54pm-11:13pm
1) well...third time on the oil door is charm it seems ... unfortunately
i have many countersunk holes to fill but it seems that the 3rd
and final fit is excellent so the door has been riveted to the hinge
to the fuselage
2) the oil door latch needed a shim which i made of a piece of aluminum...
the oil latch seems to work well... might need some polishing so
that it opens smoother but works and sits correctly so wear and
tear might be enough to smoothen it
3) trimmed the right side of the vertical stabilizer to allow 98
mm of rudder deflection
11/25/2005 5:58pm-2:03am
1) used the approximate measurements sent by the factory to drill
the engine mount holes... removed the remaining rivets from the
drilled rivets of the firewall and re-riveted the firewall into
place with some fresh silicone in the affected areas
2) drilled and bolted all engine mount bolts into place
3) re-attached all rudder pedal stoppers by riveting
4) cut the oil door and sanded the door to fit... all parts were
mostly assembled but unfortunately the hinge wasn't positioned properly
and so I removed the hinge while i still could... will have to redrill
and rivet the hinge into place...bummer because it looked so good
too...will have to patch it but I think it'll be good in the end...
i think this is really the advantage of fiberglass...try fixing
that on a sheet metal aircraft easily
11/20/2005 4:50pm-12:19am
1) so after some thinking and some looking at previous photos without
the firewall on it seems that the reinforcements are there and unfortunately
i will have to remove several firewall rivets to locate them...
but the predrilled holes aren't there and hence my problem...i'm
guesstimating that the factory stopped predrilling the engine mount
because as I've learned from an earlier builder that the holes didn't
align properly... it's very possible.. but of course giving us some
measuerments would have been a good idea
2) called Jabiru and spoke with Mark who said he will send a drawing
of where the mount should go
3) installed the battery box per instructions
4) installed the cowl hinges per instructions with tapk3-3 rivets
5) installed the front 2 camloc screws per instructions
11/18/2005 5:14pm-9:11pm
1) finished the assembly of the elevator trim assembly
2) was about to install the engine mount but don't really see any
holes as instructed especially since the firewall is already on...
will have to find out from the dealer or so as to were specifically
it goes
11/16/2005 4:00pm-10:15pm
1) the stainless M4 screws arrived for the windows... they look
nicer of course since they are stainless but the head is a bit smaller...
i started removing the factory M4 screws from the windows and it
seems that they are weak and breaking at the head because of the
epoxy.... so that slowed down things for sure...i had to drill or
break the head on nearly 100% of the screws holding the windows...
2) countersunk the windows for the new stainless M4 screws and installed
M4 stainless... looks real nice
11/12/2005 3:32pm- 6:48pm
1) drilled and riveted all hinge pins, nuts, bolts together on the
elevator, rudder, and ailerons...
11/10/2005 7:50pm-2:17am
1) checked the aileron hinges and the window that has been flocked
to the fuselage... the masking tape seemed to have worked great...it
didn't stick to the epoxu except for a few small bits that took
some fingernail work...nothing too bad... it left a nice smooth
joint surface actually... also, the soapy water on micro cloth seemed
to have worked with too..no epoxy of any trace left on the windows...
of course the painters tape is partially to credit too since it
prevented much epoxy onto the window in the first place
2) epoxied and bolted all the remaining windows and the windshield
to the fuselage... used 2 batches of 4 oz plus one 1.2 oz mixture...current
temp 70F
11/8/2005 5:45pm-12:36pm
1) stopped by home depot to see if they have the 4-6 rivets for
the trim on the elevator... i got the closest to it but it's not
countersunk...probably will just use those and then drill them later
if i get my hands on them.. also got about 20 6-6 rivets from the
dealer yesterday as requested...actually i had requested 4-6 rivets
too but they weren't in the box... so anyway, i may rivet the aileron
hinges today if i get around to it
2) drilled the rivet holes on the wing and aileron where the hinges
attach... i had to bend the hinges on the wing side because they
ran into fiberglass reinforcements...see the photo
3) sanded the hinges and the wing and aileron hinge areas for flocking
4) flocked and riveted all aileron hinges into place
5) flocked and riveted the elevator trims into place with home depot
aluminum rivets
6) flocked one rear right window into place and bolted it... also
used masking tape to hold window at the edges...if it works well
i will use masking tape on all windows...i know the clear plastic
tape doesn't stick but it leaves too much glue behind and so i'm
trying out masking tape instead...peeled the painters tape from
the inside and wiped the window down with a microfiber cloth and
soapy water...seems to have worked well....all the flocking was
from a 4oz batch.
11/7/2205 3:22pm-1:00am
1) sanded the fuselage window joints to flock the windows on
2) trimmed andfitted all windows including windshield... it seems
that the windows on the doors might have problems having all holes
drilled... the flange where the windows sit on the doors it too
narrow for bolts and nuts in many places... it's also a bit confusing
that the windows have drill marks every 3 inches or so and the manual
says only one bolt in each corner... mmm...?
3) used painters tape to mark the edge of the fuselage flange on
the windows... see the pictures...seems to work well.. sanded the
windows on the outside of the tape
