Peter,
thank you very much :)
I have spent a lot of time of internet research for hidden details.

Build recommenced after the Xmas break.
First up is to make some of the many brass fittings, including those to tie the front & rear fuselage parts together, plus some rigging brackets.
Photos below show some of the brackets before after putting in place.

Coming along nicely Peter,
Where do you procure your brass from? Is it sheet or linear metres. I have been poking around a little to find a good price, however, I think bad ole ebay seems to be the place. No-one local can compete with the prices from the internet.

Anyway she is coming along nicely and I had better post an update for mine as well, A little slack and slow start to 2019.

Kind Regards
Steve

Steve,
The 1/4” wide brass strip is standard K&S metals which I can get, together with most Brass & Aluminium tube from a good UK modelling shop such as the Sussex Model Centre. The 1/4” strip is very convenient as a lot of the brackets are 1/4” wide, so just need cutting to length.
I have sourced larger brass sheet pieces in various thicknesses from eBay to make the remaining items.
Peter

Awesome thanks for that Peter. Unfortunately its getting harder and harder for the actual shops to compete in this online era.

Remaining side strips added, including a couple of top/bottom ones which will fit under the forward mast structure & secure this to the bottom box assembly. (Jilles, I am pretty sure that these 2 top/bottom strip on each side are the SP1 items shown on one of the plan sections).

The lower rear of the pylon assembly fits into the rear of the fuselage bottom box assembly (between the rearmost part of the 0.8mm ply side pieces) & the final triangular pieces have been epoxied onto the rear fuselage boom & checked that they will be able to be slid into place in the bottom box assembly in due course.
I currently am leaving the fuselage bottom box assembly separate at the moment due to the thought of trying to handle the total assembly in the overcrowded workshop.
In the meantime, I have made & fitted the 2 skid spring tubes & also fitted the brass plates where the tubes enter the bottom box.
Lastly, lamination of the skid has started. The skid is made from 8 laminations of 0.8mm ply, bonded whilst held in place round a simple former.

Skid now complete after taking out of the laminating jig, tidying up end and fitting the 3 brackets.
Test fitted to the fuselage bottom box assembly & now just needs the forward fuselage mounting bracket to complete the setup.

Front skid bracket now made & in place (photo later), but latest activity has been on making up the rudder pedal assembly.
Photo of the partially assembled unit shown below.
The nearby plates need to be silver soldered onto the angled ends, followed by the pedal themselves in due course.
The pulley wheel is for the elevator cable turnaround from the joystick.

Some excellent model engineering work there Peter, can I ask what you are using to silver solder - gas or electric?
