The model is for a friend's daughter, and is at about the maximum size required (see,
It Arrived: Musical instrument models and
Flugel Horn). I understand about the geometry and have already given alot of artistic license without the model looking like a trumpet... the WSF version (smaller wall thickness) has also alot of artistic license to make it work) I could just scale up by 50% to get the 3mm wall thickness, but then the model becomes 75mm long and, frankly, too big for a 'girly pendant'
A support between the flare and tube would proportionately be the wrong size and look very wrong at 1.5mm (to scale the support would be about 0.2mm thick, and the model is all out of whack for scale anyway) the spec is to have the horn hanging with mouthpiece uppermost. The flare of the horn is 2mm thick all the way to just infront of the valves where the main tube is about 4.75mm dia. The forward-most loop of the tube starts at 2mm and expands to about 2.75mm where the frontmost valve tube is attached... the length of this 'free' (solid) pipework is around 50mm, much less than the 2mm rails on my
Twin Rail mobius pendant
There are several workarounds that I can try, however time is not on my side.
Included in the workarounds are;
- Redesigning for a thicker WSF model and try to get the material to soak up a low pelting point alloy (field's metal, 62 C melting point)
- Have a 3 part mould printed in sandstone and cast using a Bismuth-Tin alloy (melting point of 138 C) that is used for GW 40K type figures.
Also I have gone a different route and am waiting on a reply.
Onwards and Upwards!
