Hello folks, then let’s go, probably the last time before I start my vacation in Florida next Monday.
And from the cover plates of the Rainbirds now to the openings below, and thus the question of how to do this best, where already the marking out of the openings is not easy.
For the slender birds they should be approx. 4 mm wide and 3 mm high, and that is a bit tricky for the thin tube.
Then should also still be produced the beveling (8°) for the cover, with which I have started, but perhaps it would be better to make the opening at the end after reworking.
The beveling was still relatively easy. The only problem is that these operations and the resulting basic contour (length, incline) should also be uniform for all six Rainbirds why probably again a template would be appropriate.
Then I tried to saw the opening at a distance of 4 mm with a mini-saw blade. But the handling is quite tricky for the small diameter, and the opening should be reasonably clean.
And this is the result, which shows that the opening so is feasible in principle, but in terms of accuracy and reproducibility it is still not sufficient.
For the two thicker central birds this will be certainly simpler, because the opening is half the diameter (180°).
So I initially have thought of a template, in order to get the length and incline of pipes reproducible. In addition I have drawn the length and incline to a 6 mm thick plastic strip,
and sawed with a fine saw guides for cutting the tubes.
And so I could serrate the pipes with the slant for the covers, as I did here.
Now only the opening at the front must still be sawed. Perhaps it would be better not to cut the tubes to the final length immediately, but rather to cut only the opening, to rework it accordingly until the opening is right, and only then cut to the final length.
Then I had a feeling of success in our hobby shop where I found this nice part for the two middle Rainbirds. This is a Knitting needle with 8 mm diameter, which corresponds exactly the diameter of the thicker foot part, I have marked.
And the top corresponds to the shape and dimensions pretty much the central conical part of the bird, what really has surprised me.
Now only a pipe with Ø 6,3 mm must then be fitted with the wide opening and cover, and the shell construction is finished, that could work.
