Looks good. I do the same except my cedar fence posts are old ranch fence line posts. They have never been squared, they are just as they were cut decades ago.
Looks good. Is that western cedar or eastern red? Personally, I don't turn cedar (eastern red) as it is so brittle. Easy to have a nearly finished piece blow apart on the lathe.
No, I haven't, I put them on Facebook and, having quite a following, am making several upon request. I also post on local for sale sites. Keeps me pretty busy.
