Thanks Barry! And I'll hopefully address the audio issues going forward. 

The yoke was only ever held together with glue - wood glue to be specific. It held for ~6 years without issue so I'm not too concerned about it - and besides, I'm not sure I can pull it apart at this point anyway!

I may build a new one this winter and make that part of the yoke a single piece instead of three separate ones. That would let me sink a couple of screws into it for a more secure hold. But I just moved and haven't even found my tools yet - and I'm moving again in a month. So we'll see!
