Awesome Duncan, and that's just your sheer nerve in even THINKING of doing this!

Why does the periscope in the first two views stick up so far, and why is it slanted to port as shown?

Hi Duncan, for what it's worth I think you need to create another section between all those that you have. In 1/72 scale they space out at about 1 11/16", my experience with my Atlantic has made me realize that my section formers might have been better if they had been a bit closer together, around 3/4" I think should be about right. Mine were spaced at about 1" which pushed the envelope a tad.

Call for the men in White Coats !!!

Overkiller has gone of the deep end this time !!!

Actually I will you the best of luck with this one.

I'd say it's slanted to port because it's so tall. If it were vertical then given its length it would protrude through the fuselage when retracted due to the shape of the fuselage.
But, from an engineering point of view (forgive the pun!) it does seem unnecessarily long...

Looking forwad to the finished product. Mind you, the periscope viewer makes one think it could have been steam powered

...ok, I'm off now.

One of my favourites amongst all the "could have beens"

There was a resin 1/144th (I think) kit available but to see it in 1/72

As for the periscope I've never seen pictures of it at anywhere near that length, so just a foible of the artist ?

This is going to be epic.

Should be an impressive build when its finished Duncan. although the build should prove an interesting exercise in scratch building just by its sheer size more than anything.

Yes Chris Fantastic Plastic did a 1/144 resin display model which we have built and shown on Project Cancelled before (which is probably where you know it from ). The kit was updated a couple of years ago by adding a cockpit, undercarriage and bomb bay. S&M models have announced recently that they plan to do the Avro 730 in 1/144 scale along with the Sperrin and Vickers V-1000.

I think that will be the case, but first I will sort out the sections I do have, then see what needs adding. Getting the fuselage together fairly quickly is going to be the key here, as I only have four months to build it in...so no pressure then eh...

You've got a side view plus sections. Cut two lengths of approx size balsa planks to shape as your central core. Fit your sections where you need them, then fill in the gaps with balsa offcuts. Then mix a load of P38 car body filler and apply. More catalyst = quicker curing time. Be warned that this stuff stinks to high heaven, so best done outside or in the garage. Whilst it's curing, there's a point where it's quite rubberish and it will cut like cheese or butter, so this is the ideal time to start trimming the excess off.

IIRC, you should be able to start sanding within 20 minutes. It's nasty stuff, so wear a mask and do it outside. Whichever method you decide on to build your fuselage, you're going to have to do a lot of sanding and this stuff will polish to a glass like finish. Get it right and you'll have a useable fuselage within a week.

Balsa is cheap, easy to cut and sand, but I suggest it for the core only, mainly because it's light.

'Bout time you got started on this, crack on.

Supertom · July 06, 2011, 06:55:23 AM

How massive is this thing gonna be again? Yes, yes, it will be epic.

I think you'd want to leave the periscope stowed away, in order to preserve the sleek lines.

Also, as someone who's never tried anything on this scale, I don't have too much to contribute as to the construction, but I think Lee's suggestion of a balsa core with that P38 stuff would be the easiest way to go. The light weight would also be easier on the landing gear.

What you can do in balsa, you can do in styrene. But I am surprised how light my Atlantic fuselage is turning out, it being about the same as the B-36 fuselage was before I cut it up. The 730 is only a couple of inches longer than the Atlantic too, 26" to 24" but much slimmer, 1 1/4" to 2 1/16"

Here you go Tom, this diagram should give you some idea. It's the final variant & about a metre shorter than Dunc's version, but it's the same length as a B-52.
