So with the koozie glued, there really isn't much left but the fun part. I threw it on the lathe in my new oversized jaws and went to work. I started slow, about 500 RPM because I didn't know how fast I could go with something this size. Eventually I bumped it up to 800 and settled at about 1000RPM. I used my Sorby roughing gouge to get it round (mainly because it is my favorite tool) and finished smooth with the circular carbide tip. I also slightly rounded over the top lip and flattened the bottom with it as well.
After turning I prefer to 'wet' sand with some stuff I picked up at Woodcraft. I saw it on YouTube and have used it on my finished wood ever since. It is the combo of Doctors Woodshop of walnut finishing oil and pens plus. I use the walnut finishing oil to wet sand at 80, 150, and 220 grit. It keeps the dust down and makes quick work of sanding. I finish with the Pens Plus friction polish. Gives the wood a nice shine and is durable.
I did not do much work on the inside of the cylinder. Instead I cut the bottom off a neoprene koozie and layered it with 300 level heavy duty spray adhesive. I gently slid it inside the koozie then inserted a can to hold it in place while the glue dried.
Done. That is it. In total it took about 10 hours, but this was just a single koozie. I am pretty sure I can batch them out with little more time added to production. The backlog would likely occur when trimming the inside diameter of each ring. Turning the outside diameter was quick, barely needed to remove more than corners. Sanding was also quick. So in all fairness if I could find a better way, or simply ignore the ID it would speed the process up.
Concerns or things I would change: The neoprene insert was probably not the best idea. I did it because I was not sure how well plain wood would resist moisture and temp change like this repeatedly. It also provides insulation and makes up for minor errors within the koozie I have difficulties correcting. However, with those advantages it is still the biggest detractor. After multiple inserts and removals of a can the koozie begins to roll, peel and fray. It generally looks like a hot mess. I will probably continue to use it until another option presents itself but it is the thing I dislike the most.
The sled concept worked amazingly well. I would never have attempted such a project without it. Making my first project with such small segments probably wasn’t a great idea but it performed flawlessly. If I had a complaint it would be in ‘trapping’ segments once they are cut. The 45 degree wedge worked to keep the segments away most of the time, but there were still many times where I had to stop cutting and figure out where the segment ricocheted off to. My saw blade probably could be a little sharper, and cutting Oak may also contributed to it. However one in five segments was launched to various parts of my shop and it became frustrating and time consuming to find them.
That is it. Not sure what I can add or what I missed. If there are questions, concerns, or recommendations I would love to hear them. I can go back and try and recreate various points if you feel there was lack of explanation on how I got there, or just to clarify something that didn’t come across well. I would also appreciate inputs on writing style. I tend to me a slightly sarcastic person by nature and that tends to get lost sometimes in translation to paper (screen…see, there it goes again…).
Finally, thank you for reading. The internet is vast and unending and you chose to spend a few minutes here with me on this silly little project. I appreciate your time.
