Centurion AVLB (slow build)

[adt70hk]

Andrew,
The the 'arm thingy' is called an Antennae Tuning Unit - it is a box used for tuning in the radio(s) and antennae (aerial), and it ia on a piston driven arm that can be lifted into position to place the aerial above the bridge.
The plan for the bridge is not finalised yet, I did pose my Chieftain with the bridge partially deployed and every day I keep expecting it to be in another position...
Mike.

Thanks for the explanation!

One question I forgot to ask is what phone camera setting do you use for images. I see I am getting the thumbnail images. At the moment 4160x2340. Should it be smaller i.e 2048x1536. It will save a lot of people having to squint. Thanks in advance.

The forum will resize photos you upload to 1200 pixels (off the top of my head) along the long edge. To ease bandwidth usage and upload photos faster, I normally tell my iPad to upload the “large” size, which is 1280 × 960, rather than the full size of 4032 × 3024.

I'm in the same ballpark as Jakko, unless it's a large item like a book on 'latest acquisitions', in which case I go for something a bit smaller as you don't need a massive picture to see what it is.

I'm confused !

Jakko, Andrew, many thanks for the help.
JR Wobble, appointment booked for your analist....

Update,
So today I rebuilt the two uprights on the rear of the hull - I failed to deduct the thickness of the plastic and assumed I had done so, so now they are the size they should be.
Have been doing some work on the treadway for the bridge and did not fancy doing the flat sheet so opted for the perforated version...
After some experiments and then building a master and a few trials with getting the thickness to where I wanted it, I arrived at the final item. The ones in the last photo are for the model and will have to be finally cleaned up and trimmed to fit the main part of the bridge.

Mike.

Excellent, are the moulds something you can buy or did you make them?

Michael,
Some excellent scratchery going on I will follow along.

Nice work How did you build the masters for the treadway castings? Vast numbers of bits of plastic strip?

Jakko & Mark, Many thanks for you kind comments.
The master was made from strips of plastic care of EMA Supples, The cross joining bits also the same but cut to length with a 'Chopper' which at the end gave up and died (not really). I first made one length, then cast a rubber mould from that. I then cast two of the same from resin and joined them to make one strip/length and cast another mould. Then I went to the illustrations and drawings and realised my mistake I had made the gaps to wide across. So out came the saw and it was just a case of cutting each length down to the width I required (see to of photo) and re-gluing each length onto some thick card to preserve the shape and give the whole some strength as can be seen from the tattered end of one length. Then a final mould was cast and once happy I went ahead and cast the tradways from that in resin. This has taken place over a matter of weeks swapping from the hull build to the treadway, giving me a break and time to think out the problem. And once the hull is complete then it will be onto the bridge and I will show one side and then vanish to complete the others then the final assembly will be posted.
Mark, I wish they could have come 'of the shelf' but then I would not have had the fun of all that cutting and sticking.....:tired:
Cheers, Mike
