Yep they look great, you'd never know unless you asked or belonged to this forum!

We have purchased a stack of undrilled hinge pieces from a company in Paeroa (I think) and we will use as many pieces as we need to get the doors in place and working as they should. The doors, as they stand, are quite light and apart from the operating arms and an inner skin to stiffen the whole structure up, that should be it. It will be a case of very gingerly with the hydraulics for the first couple of cycles to make sure everything is operating as expected.

From hearing how difficult it was to come by bomb bay doors to seeing these recent photos, it is a true testament to the team at CFNZ. What amazing work! They look gorgeous!

If you don't look out you might get orders for a few more if they are that rare. isc

Anythings on the cards. Just looking today at the doors there are a few things I would do a bit differently if we had to do them again. Nothing like a little hindsight and practice to sharpen the thought process.

Yes they would probably be quite different if they were going on a flying aircraft, still you don't want them falling off if you have an engine run. isc

Ian Martin, a brilliant engineer in my books, helped us with the hydraulic rams for the wing fold and bomb bay doors an NZ2505 and is involved again with NZ2539. He has been giving us guidance on the structure of the doors around the operating arms and how they should pick up. He has also been quietly manufacturing all of the missing parts for the door operating mechanism. He has sent me the following photos of the parts he has made to date (70 odd for the doors alone) and the wing fold rams. He is currently in the process of turning up the rams for the doors as well. He makes everything but the rubber O rings. We would struggle to do the work we do without the help of people like Ian and the expertise they bring to the whole process. Thank You Ian.

On Friday Dave had the back off the main receiver unit and I took the opportunity to take some photos of the old technology employed in radios about 75 odd years ago. I'll bet there are a few people looking at this thread who wouldn't recognize most of the parts making up the circuits. Dave is currently making some of the mounting trays for the radio equipment as these are missing. I understand that he is off to the UK in a couple of months and is intending to have a look round some of the shops selling WW II radio equipment to see whether he can find a few of the times we are missing. 070619 (2) by Mike Feisst, on Flickr 070619 (3) by Mike Feisst, on Flickr 070619 (6) by Mike Feisst, on Flickr 070619 (8) by Mike Feisst, on Flickr

Beautiful craftsmanship with regard to Ian's work, and a true mystery box in your latest post Mike! I remember taking apart an old radio as a kid but I've no clue what anything inside is. Fascinating!

Don't know about now, but when I was in Scotland in the late 1970s I visited one surplus shop in Glasgow' and I think they could supply just about any radio equipment, British or American Airborn Naval, or land based, including most of a war time Radar set, Mum was with me, but she decided that the Radar set was too big for her carry on bag for the flight home(she was a WAAF Radar operator/instructor). isc

Are you guys intending to make the radio set serviceable? There are a lot of people still using valve technology in high end stereos and so there are still valves being produced in all sorts of sizes. I know a couple of people using such stereos. Maybe new tech can make old tech work. There are audiophile groups who may have bits you need.

Dave - I have passed that info on to Dave for him to consider.

I think many of the American valve/tube types are still being made in Russia. isc

Alan has managed to solve his brake problem and has re-routed the brake lines so that they are hidden away and is happy that they will hold the aircraft when we start doing any taxi runs around the hangar. Ian brought in the control arms for the doors and we started fitting them. Got them attached to the port door so we hung them and tested the hinge points to make sure we had it all lined up before we fully attached them in place. Ian still has some worries about the throws on the rams and the lining up of all the hinge points so that hydraulic pressure doesn't screw the doors up. I am glad he is involved as I would be struggling to know what to do to completely test it all. The photos show the front and rear actuating arms in place and hinged to the outer port door. 120619 001 by Mike Feisst, on Flickr 120619 002 by Mike Feisst, on Flickr

Ian came in again today to see how we were progressing with the doors. We have the port inner door hung in place and after adjusting the clevis's that Ian had incorporated we had the door doing what was required. We marked the point on the bulkhead where the inner edge of the door came to at both ends and then removed the door so that we could work on the starboard one. We bolted it into place and again checked the position of the door when fully closed. It looked a bit tight at the rear end but we have some wriggle room by moving the door in relation to the hinge point so out it came yet again and we have moved the point. Wednesday should see both hung and hopefully there will be a workable gap right down the mating faces. Not having any of the actuation items or the original doors is a pain but thats the way the cookie crumbled on this project. I am sure we will get them working as they should. Crunch time will be when we use the rams for the first time - maybe I will have a weeks holiday !

Don' call it "Crunch Time" - that's just asking for trouble! Dave D
