my Kloo-horn research

[Space-In-Vader ()]

since I made a nice vader already, I am quite familiar with details. So I wanted to make a nice screen-accurate kloo-horn. I made some screencaps and increased the brightness to see more details. In addtion I watched the "Star Wars Holiday Special"... (Urgh!... never again... what a torture) to get some more details. But the Holiday Special is not suitable (in no way) because the resolution is too low, the recording is of a bad quality and there seem to be instruments that are way different to the ANH-Cantina-scene.
Unfortunately I found no behind-the-scenes or making-of pictures of the kloo-horn so far.

just a quick google-search ("kloo horn).
for example:

these instruments looks really great to me.

When I look closer, the bottom end looks a bit different in comparison to the sceencaps.

In my eyes it looks that on screen there are black rubber-rings put on a tube. I am not sure about the area between the top 4 rings and the next 4 rings (it looks like the tube is thicker in this section), but maybe it's a matter of lighting and blur.

there seems to be a solid disc at the bottom. To me the whole tube looks like it is not simply round: the sides seem to be flatened. I have no idea what they used for this prop, but I guess it's some piece of technical equipment like a part of an airplane-engine (like ig-88 etc.).

Regarding the fact that they used a lot of aircraft junk (http://www.starwars.com/news/from-world-war-to-star-wars-the-meteor) I guess that the kloo-horn is made of a camshaft.

This assumption would explain my perception that some parts of the kloo-horn seem to be not round and that there are metal rings on the tube between the black rings.

A camshaft is very heavy and solid: so if they used a camshaft, they might have made a mold/ cast of it to make a ligthweighting copy made of fiberglass.
To make my own kloo-horn I thought about using aluminum or metal-tubes. But regarding the weight and costs I will use acrylic glass and plastic.

the top of the horn... I have no screencap that shows the top. But if this is a good reference (the horn looks like the one seen on screen, the masks are nice and even the silver item in the background is the right one, lighting and even the fog matches... I suppose this is a behind-the-scenes-picture) the top is just a cylinder with a flat base.



Today the first acrylic-glas-tubes arrived. Next will be some thin sheets of acrylic-plates... I hope I will be able to bend and cut them the right way.

looked again at the sections that seemed to be not just round like a tube but a little bit flatened. Compared this to the behind-the-scenes-pictures. I see that the special areas on the screencaps are all a little bit blurry. So maybe this is a thing of light exposure on film and a thing of motion. My conclusion: I revised my point of view and now I think that the horn is a simple tube. No camshaft, no molding.
