Although Late 302 is among the most sought after kits I haven't ever seen it built.

Time to change this sad stats and seriously decrease the value of my stash by building one

The kit comes without decals so one of the first task was to get one. I bought a book about french flying boats that I could not praise high enough

Based on the information from the internet and this book I have ordered a custom decal. It has arrived recently and I'm very pleased with it

The decal was designed and printed (with white, otherwise I would print it myself) by a man called Alexey, check out his portfolio, highly recommended

Another problem is that the transparent parts are all yellow and cannot be used.

I decided to vacform my own using kit's canopy as a master. On the right is the canopy from Bizerte that is even worse. I will try to utilize the abilities of my vacforming machine and fix two problems at the same time.

First step - create a positive silicon form

once the form settles I will take a negative silicon form from it using separation fluid and cast a negative resin form out of it.

Well done Alexey

Really pleased to see this one joining the GB.

Given the rarity and value of this kit do you want me to organise some round the clock security for the build on BM ? :fight:

We can't take any chances !

cheers Pat

Thanks Pat, but I afraid after this little operation the value of this kit has seriously deteriorated.

Are you as excited as i am?

Things are not so good on the canopy front. The positive silicon form is not good at all, the surface is quite uneven, I duspect because of improperly applied release agent. I don't have enough silicone to make a new one at the moment so I either a. get more silicone and retry, b. use positive form for vacforming or c. do not vacform at all - all the windows are flat so probably it is easier just to use transparent sheets to make them

Great to see this one started, excited what gave you that idea  :jump_fire:  ;)

 

Its a lot of glazing to do with flat sheets, I would be tempted to try the vacforming again when you have got all the suitable materials, for example more pink lego !

 

I also checked out the reference book which is superb but also blooming expensive, so I will have to put it on next years Christmas list.

 

cheers Pat

What release agent are you using?  I've found this one very easy to use: http://tiranti.co.uk/product-category/mouldmaking/silicone-rubber/formula-5-release-agent/


I generally use two coats for casting silicon against silicon.

Thanks Robets, probably worth a try. What silicon do you use it with? 

One of possible causes of failure is that both my rubber and release agent are way our of their "best before" date so I need to resupply. I used to deal with Sylmasta 370 silicon and release agent that needs to be applied with a brush, being old both substances are now much thicker than they used to be. Although I'm generally happy with Sylmasta I would probably try something else and aerosol agent seems more suitable than brush applied,

Generally with tin based silicones - from their mixing proportions and labelling, I believe Tirantii's silicones are tin based.  Any other silicone I've used has been tin based from Notcutt.

Both good friendly suppliers.

 

Looking at Sylmasta 370, my guess is that is tin based too.  (Platinum silicones generally use 1:1 or 2:1 silicone/hardener ratios, tin much less hardener to silicone.)

 

The best before date should be respected, especially if the tubs have been opened.  I stand to be corrected, but I believe the stuff starts curing in contact with air.

Having said which, there are a few neat tricks here (pun intended) https://davidneat.wordpress.com/materials/mouldmaking/silicone-rubber/recycling-and-fillingextending-silicone/

Sorry Pin, I generally discuss my mould requirements with the supplier.

Having said which, from Tiranti I've usually bought their T20, which has a low Shore A hardness (16) - i.e. its a soft, flexible silicon, easy to de-mould though it is vulnerable to tearing.

 

Note, my usual materials should be kept below 60 C, lower, I think than vac-form plastics - you'd need to check suitability.

Although this project has moved to background it is not abandoned completely

 

Resin parts are well below modern standards. Indeed, both materials and technology leaped massively in 20 years. Pretty much like Lubuntu that I'm using to write this post vs. OS/2 I used back then

Some parts are easier to build from scratch that to extract something useful from resin bulbs. Control columns for sure

 

571030-15048-71.jpg

 

 

Cleaned, not that scary

 

571029-15048-68.jpg

 

And primed. Caverns - check, bubbles - check, brittle and hard resin - check

I'm keeping removing parts from sheets, the thing is quite big, just look at these wings!

Talk about old tech! Your Latécoére has cleaned up nicely

 

Lubuntu is a new one on me, I've used other Linux systems including Ubuntu, but had to google Lubuntu - way off topic, but I wonder how it compares with the usuall systems?

Where else can we discuss operating systems? ;)

Lubuntu is basically Ubuntu with LXDE desktop environment. The difference is that LXDE eats far less resources than GNOME that makes it possible to run Lubuntu smoothly on relatively old machines of which I have plenty.

Although my main workhorse is quite powerful Dell XPS 15 with 32 GB of memory onboard I still use Lubuntu on it to keep my IT zoo homogenic.

Windows 10 is an absolute abomination (so is OSX but to lesser extent)

Not easy in this space.

I'm stuck with Win10 these days*, but still write stuff in the old scripting languages.

 

* Though I agree with your sentiment about the environment

I'm not ready to pay to mr. Nadella for professional license only to prevent it updating when I don't want it to (and for useless, uninstallable cortana too)

Those wings look enormous, more like a pier for the other aircraft to tie up to !

 

Look forward to seeing the next instalment, and great work on those Resin parts.

Working on transparencies. Trying different options

 

582365-15048-98.jpg

 

Let there be foam!

582367-15048-42.jpg

 

Scary? Not quite

582366-15048-96.jpg

Most of the foam goes to the bin

582368-15048-31.jpg

 

Strut is needed to provide correct wing dihedral.

582370-15048-40.jpg

 

With more than half metre wingspan the beast is going to be the largest on my shelves once complete. B-17 wing for comparison

I know, I know the GB is over, but I'm busy, very very busy now.

In a meantime, are there any ideas about interior colour? Bleu de nuit?
