As it takes a few weeks to get the build file validated I have sent this off now and have put all the relevant papers and notes and sign offs into one folder, hopefully in a logical check sequence for the LAA using their very useful step by step ‘do and don’t’ check list

Got lots of things to be getting on with finishing off ready for engine testing and readiness

Time to get the panels day for fitting in situ

Such a warm day yesterday in Jersey so a good time to get the panel covering finished

Once dried I can trim out the centres and get the dials back in

Have used handshake connectors throughout which should make life easier for in- out checks

Had my engineering mentor down with me .. Good Mr Fleming …

he took me back to first principles of solenoid connections and also we stepped through the initial test wiring I had created.

Turns out I had missed a wire ! So checked it all through, drilled the bulkhead for an additional earth wire .. Located a suitable chunky bolt on the back of the engine and attached earth cable. Ran it through new grommet end hole and secured along the way.

Temp attached started cable and flicked mains on and pressed the starter  ! Bingo .. We have life and a quarter turn of the prop !

now to push on with instruments connectivity

With the LAA flight test forms about to go off there are lots of bits to complete …

Heat shrinking sleev to protect power lead … grommented through bulkhead

Solenoid fitted to battery tray

With recent incident I read and the factthat I have put the wheels on and off around 3 times so far another check that all 12 bolts are tight … checked ok ..

Both footrests prepared ready for fitting once i confirm the lie of the material

Covered dashboard having fittings re-applied ready for wiring up

Reckcon lower body and sides will take about 3 evenings

After all that covering .. time to re-weigh and see where it all settles out in terms of weight and balance.

Got 125Kg on each wheel and 10Kg on the tail. So all up it’s not looking too heavy.

EMPTY – well allowing for me as a 75Kg Pilot sitting in P1 AND with a tank of say 40 litres of fuel the CofG comes out at 185cm from my datum (rear of the prop flange) ..the TLAC stated CofG is between 180 and 190 from that point ! so smack on midway ….

Trouble is life isn’t that simple and you need to cater for the normal ‘flight operating window’ ie taking off with a load of fuel that then burns and changes the CofG

The ‘trick’ now is to use the LAA template to work out the worst case forward and worst case rearward CofG points. If fuel is burned off to say 1/3 of the tank the CofG moves rearwards by about 10-12 cm ..I am going to cross check this with Paul to make sure my figs /maths are correct as ideally i do not wish to put a chunk of ballast in the nose 🙂

Luckily the P2 – Passenger is pretty much dead on the CofG so doesn’t majorly affect the balance point.

With work going crazy and flights tobe made toLuxembourg (a very very long runway of 4k+ !) and last weekend Paris/Toussus .. I have finally managed to get back to some work on the Sherwood.   I have made so many lists of things that need to be finished off … so this session has been lots of those … struts covering (decided Olive Green would contrast the predominance of cub yellow  !) … electrics cabling from battery through the bulkhead to the solenoid …   Brake turnbuckles…. re doing some top covering (more on that later) …   Also, post the LAA recent article ..a full re check of my 12 wheel nuts for tightness ….    

Oratex is amazingly strong and opaque ! Once you have an overlapped joint – re finding a pre drilled rigging hole involves some very bright lights to see if you can see through the covering to re find the holes. Then a nice hot soldering iron through and bingo …

Also get the wires properly labelled with the RS coding method

A few unusual shots as I was under the ‘plane checking transport after the static show

Sherwood out on show and answered about 1 million questions as the interest levels rise !

Out of the barn and connect up the trailer .. took around 4 hours to rig from scratch ie all wings, tail, elevator, rudder etc

The Arrows arrive …

Andrew (Koester) very kindly popped around again to assist … he had won one of the charity raffle prizes to spend 1 hour ‘plane building !

He is now over 6 hours into his 1 hour prize !! Well done and much appreciated Andrew ..Having learned the art of gluing and fitting reenforcing Oratex strips we moved onto that 3 handed job of fitting and drilling the perspex windscreen fittings.

The first hole was drilled without a support alloy strip behind .. but ran the risk of the drill going through the body and then whizzing through the perspex and marking the inside of the cockpit coving … Andrew ‘back filled’ and we drilled all 22 holes (11 front, 11 rear).

With so much swarf around my nice clean screens we elected to cleco as we went, remove everything once drilled , blow it all clean and then re-fit.
