It was finally time for the scariest part of the hurdy gurdy build. Bending the top plate of the body. I placed a short wood piece along the length of it and tie long cable ties around it. The whole thing was then placed in water for about four days, while continuously tightening the cable ties every now and then.
I could then glue it to the body with lots and lots of glue clamps. I did a dry fitting first to figure out where to place clamps and how to get it to be placed correctly.
