As the sanding is going to take some time I am deviating from doing one job at a time in the thread and moving on to fitting some of the body together with its wings and fins.
Now Bachem probably had some great jigs when they built the real thing even though it was made of spit and kleenex (Just like the model
) But I bet you couldn't eat the jigs at the Bachem factory
Heres the first jig I used to get the rear stabiliser on - this actually failed and meant the fin had to be cut away again and redone but the first pic does show the advantage of having stuff marked up from the off with the Natter - all those alignment marks make for an easier time getting fins on because the Natter is not round like a rocket and in fact its not even that regular. If you looked at my build in your hands you would see one side is a bit flatter than the other due to the deficiencies in the former/centreing rings. With the great benefit of hindsight, which is one of the finest ever invented diagnostic tools, I would have cut the rings myself and maybe gotten a better accuracy.
The second jig is the most edible of the two being comprised of tins of fish, curry paste and rice pudding - it also worked better at getting that rear fin well aligned. YOu really do need to be able to get a good view front and rear to make sure the alignment is good all round.
I went with the vertical stabiliser first because it was easier to get alignment on a vertical with the kit than to get a good horizontal alignment for the wings due to the shape of the body. The first go was with an Epoxy which just never really set properly for some reason. The second go was with Bostik Serious Glue which needed two hours but its well stuck down now. I may add a fillet of epoxy later to this fin.
Heres the great food stuff based setting jig
The body is strapped to a tube marking guide and orientated to be vertical with respect to the alignment marks on the tube and the marks on the centreing ring, a strip of card holds the fin upright, this has been cut to be a good right angle with the glass table surface and have a cut out to allow the body to go under it and a steel ruler taped to a tin of rice pudding holds the fin against the setting guide.
The plastic tri squares are to use as sight guides down the tube to keep an eye on things.
