Thanks for thinking of me. Sorry been a bit preoccupied lately. I also had a brain fart on my drawings & concluded circular disc shape wont work very well in any orientation just based on the rectangular-ish dimensions - other than lopping major sides off a log which just isn't practical. I was able to make some chuck plates from some ground cast aluminum stock I had on hand which worked out ok, at least for now. plates My major headache when I have some time is resolving my lathe issue.
