[hey there flyingboxcar, your latest updates are looking great. What size feul line (copper pipe) did you use? I have got 4 different photos and the scale goes from 3 to 3.8 mm but i dont want to get it wrong.]

I have used 1/8 brass for the fuel pipe
 In hind sight should have used copper.
Hope that helps

It certainly does. I will get some today, but i think i might make it from solid rather than tube as bending tube that thin is going to be a devils own game. Many thanks flyingboxcar

Bending the 1/8 tube should not be an issue. The solid one will add weight. If you have spring benders it can be done or else just anneal the tube then it can be shaped with bare hands.
And get more than one so that you don't run out if the first one does not turn out as desired.

Spike,
Another tip regarding bending tubes, that I learnt on RC Scalebuilder forum.
Insert a piece of soft solder wire that is slip fit in your choosen tube. Bend to desired shape and pull out the wire. If the solder wire breaks or snag, heat the tube and the solder will flow out.

Some more details have been since made and added on to the model
1. The head rest former's for the two cockpits. These were measured and cut in paper first and when satisfied with accuracy was transferred to 1/64 ply with appropriate cutouts etc. These were then clad in thin genuine leather.
2. For the front cockpit, handholds were formed out of lithoplate and fixed. Here both pieces can be seen together
3. Fixing attachments for the Sutton harness were made out of thin Ali sheet. Bolted on using M2 hardware with 5mm  brass pulley riding on the anchor cables that had been added much earlier in the build. Pulleys allow the fittings to ride freely over the anchor cables
4. Closeup of the attachments. Next job would be to sit the pilot and size the Sutton harness.

Thank you folks. I have been trying but I must confess the workmanship leaves much to be desired when compared to many other master craftsmen who I admire and follow.
I think I will be satisfied if it looks the part from 6 feet Smiley

One more box ticked off.
The tail wheel assembly is complete.
The wheel yoke is 3D metal printed, that is silver soldered on to piano wire that goes through the undercarriage bracket and rest of the bits and bobs are soldered and bolted together to make it look something like the full scale.
All that remains is a lick of appropriate paint on the bare metal parts to blend it all in and then fill the undercarriage bracket tube with some grease to lube as well as prevent rust between the tube and piano wire that is enclosed

The Tiggy (Fuselage only) go to go out to the field over last two weekends. The idea was to run the engine in the air frame and see what fails/gives. Plans were also drawn to check various props, therefore a tacho was put in the caddy, and a fish scale carried along to just see what the engine/prop combo pulls on level paved surface.
Well first outing the Tiggy only got some tan and fresh air as it was realized that the tank lines were mixed up and I did not want to investigate and fix all that at the field. Back at home things were all corrected and tidied up in preparation for next weekend.
Come next weekend the Tiggy went along for a ride to the field. All fueled up, a choked flip to prime, glow live and the Laser 150 fired up right away.
While setting up the tune it was noticed that copious amount of fuel was flowing down the cowl pan on to the grass. This all happened in first minute of the engine being started.
Engine was promptly shut down and a cursory look revealed a disaster.  See the pictures

The unrestrained tank had moved up and welded itself to the hot bendy pipe exhaust leading to a fuel shower.

Any further attempts of shake down or excursion to the field are on hold till a replacement tank is sourced and installed with corrective measure to prevent any repeat of the incident.

Managed to set up the dihedral and sweep back etc. One heck of a job to do and still one wing tip is different from the other by around 10mm and I have decided to just live with it.  Next job is to lock up all the landing and flying wires etc and fix leather pads between the incidence wires and put on the long acorns between the flying and landing wires.
Also fitted the ASI (used double sided tape to position and will use c/s self tappers to fix in position) and on the other side fitted the static and pitot tubes. The tube terminates at the lower wing near the front strut in thin dowels that are just plugged in. In case the strut needs to be removed the whole assembly can be removed with the strut without damaging any part.

Sir,
If you calibrated the ASI, and put a one way sawtooth ratchet under the swing arm, youíd have a ready record of the max airspeed achieved...
(Those who can, do. Others preach. I fear Iím falling into the latter category  Grin)

Pl include a foot rule in your pics to give us a feel for the size of the part in the pic.

P.S.
A scale model like this needs a scale airfield.
We have one. Just right to test fly your Tiger Moth. Grass runway.
Iíll arrange accommodation too.
Please do consider.
Regards

Iyer sir,
At the stage I am with this model I am running out of patience. So the ASI will remain as is and then the ratchet wouldn't be scale, no? If I am looking to measure speed today telemetry offers much more accurate reading than an ASI that is being pushed by the air stream. Even on the full scale I suspect that it was used as a rough and ready guide rather an accurate instrument.
What would constitute a scale airfield? Just a 1/4 length runway or all the buildings and people too scaled down to quarter of full size?
Thanks for the offer. I do have access to grass runway where I regularly fly so that should not be an issue. Moreover with a tail wheel instead of the skid the model will also handle paved surface equally well and that too is available.

Manish,

Just popped by to see if there were updates. We have had a mild winter in the UK and I flew my Moth in February, we had a week of light winds and record 17degC. Your ASI and pitot tubes look very good and what I am really impressed with is the finish on your interplane struts. Did you make these per the kit with laminations of balsa and spruce, because if you did and then got consistent coloration of the two different wood types I take my hat off to you Hats Off.

Peter.

Thanks for dropping by Peter. UK flying season should be opening very soon. Wish you happy landings.
On the struts, yes I did make them per plans and then used PU stains, and clear coated with auto enamel. I would have liked lighter colour to represent the full scale more accurately.
The bracket that holds Pitot etc was carbon fiber and came with the kit. I did make up the rest with some bent Al tube, rubber tubing and winding wires. While you left the base hanging I have push fittings.
Your fittings with brass and all was a class apart

My kit did not have the piece that holds the pitot tubes so I had to go my own way on that.
