Jim, I’m just a couple months into this. But today I made a lazy susan from some things I had laying around and it is a really nice addition to my toolset. I just checked Amazon and they have several lazy susans, some of them under $10.
I understood the same as Serge – northern basswood is best. I understand from other posts on this community that “northern” is what Mary sells. FYI, I compared his price against what I got from Woodcraft (I have a bandsaw and cut my own blanks) and I think Mary is priced fairly. I’m also intrigued by his EZCarve and may order some.
