Hey, nice bow! Love the shape.
Was looking around to get started on my first takedown riser!
Just my opinion, I think the shelf area is a little narrow. Not much wood there to hold up the poundage. Maybe you wanna give that spot a check? Might be the cause of the cracking sound!
Just my opinion though, might want to wait for Roy or the rest to give you some real tips!
God bless!
