Thank you.

Been a crazy night, we had 4 power cuts and each time I was trying to develop this solution and post the questions!

Hugh, if you mean the tailplane support strut its not an oval tube. Its a round tube with a wooden fairing screwed to the rear of it. Well it is on a 82a 🙂

Yes you are absolutely right!

A bit of misdirection on my part I’m afraid – my mind is obviously not focused today – I should have said the elevator balance arm!

The drawing is not clear but I think it is about 1″x0.4″.

Unfortunately there’s a lot of key information that is barely legible on these drawings which means I have to continuously dart back and forth, cross referencing between the parts and assemblies trying to determine missing information. In this instance I deviated to do some work on the diagonal strut; checking the connection to the fuselage; when I wrote the message!

Do you have a copy of the Drawings for the 82c that are available on disc?? usually available on ebay at a very reasonable price.

Yes I have those, sourced copies from 3 places – originally my intent was to cover the DH82A but the first set I bought was actually the DH82C, then someone else was selling a copy stating the DH82A but it turns out it was the same – finally I obtained another copy that had been digitally tidied up – which as it turns out was certainly worthwhile.

I have so many questions – bottom diag brace on the rudder, leading edge member on the tail fin, eyebolt to the fin post to match the rudder hinge, trim tab on the elevator, the main fin rib dims, main rudder rib offsets, tailwheel size and so on…and thats just the tail!!

I don’t believe I can finish this project with the information currently available so I have decided to postpone it till a later date.

Most impressive!

Certainly looks familiar!

Thank you very much.

To date this has probably been one of the most interesting and challenging aircraft projects I have done.

Your photograph highlights one area that still puzzles me, which I have yet to satisfactorily resolve and that’s the rudder forward diagonal from the 2nd rib to the leading edge.

According to the information I have this appears to have been removed from the DH82C – yet I see no logical reason why they should do this!!

I have made some enquiries with various museums that have restored this model to see if they can throw some light on this.

With the level of detail you are going into, can you produce a set of drawings that could be used to build a fuselage (including the various stress calcs).

cheers

Hi and thank you for your interest in this project.

The models; dimensionally; are well within tolerance and accurate beyond the normal requirements for fabrication.

However to prepare a set of drawings to build a fuselage; I don’t think this would be practical; as I would need access to the original jig drawings, full material specification for the original design and the contemporary equivalents. Then approvals and certifications would also need to be sought.

These projects are a personal endeavour to develop highly accurate 3d models of various aircraft and where appropriate fully detailed 2d drawings for the purpose of research, accurate model making and as a reference. The final cad models are converted into a 3D format that can be viewed, interrogated, measured and sectioned by anyone utilising current readily available software.

Anything else beyond this scope is of course possible pending access to critical and verifiable information, which historically has been difficult, so I therefore need to restrict the practical application of this project as noted.

Updated Model:

For reference; attached is the latest model for the undercarriage showing the forward radius rod arms. As you can see these items are floating with the connector brackets somewhere lost in space.
