My apologies for the lack of updates for so long. As my son was going away to college and needed to take the organ with him, it was a huge rush to get the instrument functional, Good news is it has been working flawlessly for several years. He is now back home due to COVID-19 with the organ, so I'm finally able to provide more detail about the construction.
Thanks for your patience, look out for updates over the next few weeks. Also thanks to COVID-19, I got laid off this week, so will definitely have time to complete this.
