Cant imagine how much time goes in to that ! You have way more patience than I !
Nice work ... Scott
Not too much. Rip staves with 18 deg each side, for 36 deg included angle. 10 staves glue together to make a circle. They will fit better to glue 5 and 5 and flatten and glue together, I use titebond. Slice into segments about 1/4 to 5/16 or what ever suits your fancy. I make the walnut veneer to suit what ever look I want and cut out circles with a 1-1/8 " holesaw, with the guide bit removed,on the drill press. The stave glue up is about 1" diameter, so the circles match. Glue the segments and circles together. I use med CA and glue in pairs with a walnut between, the glue pairs until you get the length you want. I set the pairs in a 90 deg V corner to help keep the stack straight. I turn between centers to true up and to a diameter suitable for my collet chuck, usually 3/4 or 5/8. I cut then drill on the lathe using the collet chuck, cut a little long then trim. incase of some chip out. Turn carefully and flood with thin CA occasionally to fill voids and strengthen. I finish with about 20 coats of thin CA. With the technique I use I can apply the CA in about 5 min.
