Progress... getting on a roll.

Tuesday evening... (Sept 2, 2025)

Pin keepers installed in the stab / elevator / trim.  THAT was a challenge solo.  Thank god for the body work stand.  I use that thing ALL THE TIME.

I was flying solo tonight, so had to get inventive on how to hold the elevator up.  Tape worked!

Peeled a lot of tape off the front window... looks reasonable, but not perfect.  I think I can fix the problem areas.  Also got some silpruf on the interior, but it is coming off with a bit of effort.  Forgot to take a pic.  2 days until the clecos come out.

On the last engine run the pipe off the turbo had a shake.  It was only supported with 1 mount, and its a long pipe.  Added a second mount at 90 degrees (roughly).  I think this will work.  It is definitely less 'shakey' just wiggling it.

That was a 3.5 hour evening.  But it was definitely progress.

Front window came out of the clamps!

Looks pretty good.

Put lock nuts on the new exhaust clamp... I found some.

Installed Deutsch connector under the tail cone for the rudder trim.  The bulkhead connector finally arrived from China.

Seriously impressed with these connectors.  The elevator side has been converted (from molex) as well.

OK, well my trim connector upgrade did not go as planned.  I temporarily assembled everything to test the wiring, and nothing worked.  Very quickly I found that the thin 26 gauge wires were either broken, or about to break.  I have spliced on larger gauge aviation wire on both sides and am testing again.  The ray allen 5 conductor wire is very thin and weak.

The strange / weird thing... I attempted to use solder sleeves to graft on new wires.  The solder in the sleve would not stick to the ray allen wire.  I ended up tinning them first with solder and an iron first, and then using a solder sleeve.  I did a sample piece first (finally learned my lesson) and it is a strong joint now.

I put everything together, and nothing would work.  Zero.  Took it all apart and realized that on the socket side I did not have the pins fully engaged.  It seems like there are two 'clicks' when you push the pin / socket into the connector.  I only got past the first 'click' the first time.  Once fully engaging the pins everything worked as intended.

Checking the elevator travel.  Manual calls for +23 and -20 (+/- 1 degree).  I am getting the -20, but not the +23... about 2 degrees short.  Filing the stop plate through the belly inspection panel.  After an afternoon of filing and checking, I gained a degree.  One more to go.

Sunday... Sept 7

Put the prop on.  3 times :-)

The manual says to pack the cavity between the thrust bearing and threads with grease... it says to use a spatula.  So I did... the blades were not fully seating.  The ferrule was lose... and it was visible.  Later the manual says too much grease will cause exactly this.  So I took it apart and cleaned out the grease and reinserted the blade.  Was better, but not correct.  So did it again.. on each blade.  Finally they were all seating correctly and torqued per spec.

Next was the bead of silpruf between the window and fuselage.  Lots of cleaning of crap out first... my theory is to get all the leftover crap out.  The 'dressing' needs to stick on all 3 sides.  So lots of pulling out the leftover bits (I could have done a better job during the insertion of the window... being honest).  Then taping the gap... 

Then cutting the gap...

Then filling the gap and smoothing it...

That was a 10 hour day... Monday will be seeing what I have... fingers crossed.

Progress... and going backwards.

Positives and negatives this week.

Clear was shot on a ton of parts yesterday.  Struts, flaps, right wing, elevator, spinner, etc.  Most of it looks good, but the wing does not look good.  One side is flat and orange peel.  Not sure what the plan is at this point.

So I got to work on the fuselage.  I have the rudder and stab, so getting everything in the fin and aft fuselage ready.  Everything is torqued, torque sealed, cotter pinned, etc.  Elevator bell crank, rudder hinge bolts, tailwheel, etc.  And I cleaned... and cleaned.

The front window looks like its going to be good.  Peeled a bit of tape away to peek.

Rudder installed, all cables connected with correct hardware, etc.

Prepping the stab and elevator for install.

Door seals installed.

Sheerwebs in the tailcone... these have been on the shelf for years.... What should I have been an easy job took hours.  The issue:  The SB that adds the reinforcing plate to the vertical fine (upside down pitchfork) moved the attach tabs back slightly.  So nothing fit correctly.  Had to open up the holes in the angle brackets on bulkhead C to adjust the alignment.  Lots of cursing involved in this one.

Mated up the stab, elevator and trim tab.  The pins went missing (again), but luckily had enough material left to make new ones.  I think this is the 3rd set I have made.

Still need to put the pin keepers in.  Then the whole assembly can be installed.

Should be getting more parts back this week.  The marathon continues...

Horizontal Stab, Elevator Fairings, Tail Cone, Elevator Trim

The Sportsman has been in the hangar for a couple months... progress has been slooooow.  But finally starting to pick up some speed.

There is so much to do... almost an overwhelming amount.  So I finally decided to focus on the tail.

Elevator fairings:

Initially I fitted the elevator fairings.  Followed the manual, got everything trimmed and drilled.  And THEN I mounted the elevator and tried to align the horizontal stab portion of the fairing.  Well.... they HS portion is not long enough... or more accurately the elevator portion is too wide!

The problem... I already drilled the holes.  However, I only drilled them with #40 bits (not #19 as specified in the manual).  I had to cut 0.75" off each side in order to get them to align, and then carefully mark and redrill the holes.  

Then I figured I would just do EVERYTHING on the tail.  So onto the tailcone.

I had to cut a slot in the bottom for the tailwheel cable lock (not a steerable tailwheel - but a fully castering, lockable, not steerable tailwheel).  The slot has weakened the tailcone... so planning on 2 additional fasteners at the bottom in addition to the standard 4.  I still need to make the slot slightly longer, and put a grommet on the cable.

While I had everything apart, I put in the elevator pushrod and temporarily connected it.  Man, the elevator is HEAVY without any counterweights.

Then reassembly to start on the rudder base fairing.

That sucker is going to need a lot of trimming.

PROBLEM... my lower rudder hinge is not in the right spot for my rudder.  The lower rudder hinge and vertical stab spar was installed by another builder.  I will need to offset my hinge 0.2" to port.  Will have to get a new bracket machined...  Need to disassemble to do so.

Time for a lot of fasteners!
