Thanks for the compliments guys.
No this is not a kit. (In fact I didn't know you could buy a kit.) Everything you see I made from materials I had on hand, (obviously I didn't make the wood!) including the loop in the top. I had some end cuts off some maple butcher block for the top and bottom, and some thick scraps of cherry for the body. No problem to get maple scraps for the peg from just about any 3/4 scraps lying around. The loop is beading wire from Walmart (I made some beaded icicles last year).
And yes the top and bottom are tenoned to fit the hollow body. The holes for the perch peg and entry are drilled first, then the center is hollowed out by drilling with a spade bit on the lathe. And then, since the spade bit isn't rigid and it makes the hole off center, (man I gotta get some Forstner bits!) I re-mounted the body on some cone centers improvised out of wood, trued up the outside, sanded, and burned the lines in. Then the tops were tenoned on one end, mounted in a scroll chuck, tenoned to fit the hole in the body, then shaped, sanded and parted off. A hole is drilled for the loop, then using those round jawed beading pliers, I wrapped the loop and glued it in the hole.
