Now the frame and the rear chain stays are ready, they can be joined together. At first, I thought I would use dowels. (B.t.w. is that correct English? I mean wooden sticks to insert in both parts.) However, James stated in his design that just epoxy would do. So I glued them together and clamped them for 24 hours. Here's the result.
Please note there are two additional shelves at the outer sides of the rear stays to prevent clamping damage.
Keep on cyling!
