The parts are now separated/cut, ready to build, but I fear this will not be easy, maybe with adhesive tape holding parts during glue drying?

My adhesive tape try is not very good but it shows the project:

I recall some articles mention reinforcing fuselage and/or wings. I've been wondering if polyurethane glue and water can be used to fill a vacform component.... I think it takes just a little water to start it foaming.

I have not this product. I just started to glue, holding it with tape while drying, solidifying... (I hope):

One thing I usually do with vacforms is insert a bit of sprue running through the fuselage wing root to hold the wings on. This will give you a stronger attachment than just butt joining them.
Do you mean a vacform model is intermediate between an injected plastic model and a paper model?

I'm sorry I missed this, Tophe. I've been ill with flu which is less fun than PSR.

I didn't mean to suggest that but now that you mention it, one could think of vacforms as intermediate in structural strength when compared to paper and plastic models. Whether or not you want to reinforce the wing joint might depend on the plastic. I've had some vacs where the sheet was so thick it didn't need any reinforcement. I often use scissors myself on these kinds of kits. The ones from the former Eastern Bloc countries are especially tough.

I really like where you're going with this model and I think you will soon have us delighting in your latest marvel, mon ami!

Thanks for these details!
I have used your sprues recipe, thanks for that too!
And I have put a thin layer of putty, not to dissolve the fragile plastic. There will be more and more later. :smiley:
Good recovery from the flue, Brian.

And, as well, a first little layer of putty on the underside, reinforcing the spars:

The silhouette is more attractive with the spinner glued in place. I will have putty work to operate there also.

That's coming along quite nicely, mon ami!

You have some serious vac skills!

Glad I could help a little, Tophe.

Thanks again.

Well, I went on a little, sanding the propeller basis bulbs on the spinner, alas that produced holes (see below, left), thus more and more putty (below, right):

After the first sanding, it takes shape, but lot remains to be done...

Now that the paint work of the other model (Gee-Bee Zwilling) is finished, I have been authorised (by myself) to continue the sanding of the MiG-3, then starting to glue the lifting areas...

It looks like you're having a wonderfully productive weekend, mon ami.

There is something meditative about sanding. I've been doing a fair bit of it myself lately.

Watching with interest,

Continuing to glue and support with pieces of sprues. This is impossible this way for most of you, serious modellers, but as I ignore the underside, it is all right for me... ???
