Intonarumori nearly finished

Here's my finished Intonarumori. OK I've still got to varnish and tidy it up.

 Here's a close up of a small brass pulley wheel I put on the sliding mechanism. this improved the performance.

 I also put a smaller pulley on the lever arm this again improved its working by not tightening the string when it was drawn back. This was happening before and making the sliding bridge not move smoothly.

 Finally I added and alternative spinning disc which plucks the string.

Here's it in action,

I'd still like to improve the tone it doesn't have the nice rasp that Jonnda's has. I will try his recommendation of using cello resin on my smooth disc.

I now hope my sons will try it out at one of their Circuit Breaker gigs. https://circuitbreakerband.com/

Well it took me nearly 6 years to finish this project. I must now turn my attention to the Laurie Anderson Violin I was making.
