[Sequel of the post Grierson's Whistle: drawing a template]
In his patent, Alexander Roxburgh Grierson specified his whistle was made of metal sheet. So I used (again) a 0.5mm thick tin plate, and glued my template.
I roughly cut the piece with a pair of shears, and began by the easiest: rounding the upper lip rest around a pencil :) Whether it had been manufactured, the Grierson's whistle would have been stamped, and this lip rest would have been the the "positive" of the mouth hole. I'm not able to stamp tin sheets, so I cut a separate part that I will solder at the right position.
Then I shaped the parts more precisely with a file. I also used a metal punch to cut the narrow curve of the wings, and also to remove metal from the mouth and nose holes, before finishing them with the file.
Bending the longest part was a very difficult task. I used pencils and rods of different diameters.
Then I began the soldering, and noticed 1mm was lacking at the very end of the curves. I had suspected that those curves would have "eaten" some length, but my cardboard model was made of a thinner material than the tin sheet, and I made this little mistake...
Finally, I soldered the upper lip rest.
Then I filed and sanded the instrument. It is far from being perfect... But it's been the most difficult replica I made so far. And I'm not proud of the quality of my solderings...
To be continued!
