Additions to the frame

I added a support beam connecting each end board at the bottom for extra stability. The pedal will also eventually be attached to this beam.

The string hooks need some type of buffer between them and the keys, otherwise metal would be rubbing against metal. You can buy latex tubing on Amazon that works perfectly for this purpose. Even when the key are touching the latex, it barely dampens the bar at all. The tubing also elevates the bars even higher off the frame. 

I made a video to show how long these keys will resonate even without resonators. 

Next up: resonators. I've already tuned the first 6 of them as of posting this.
