Thanks for posting these Ed. I have spent the last few days getting my kids set up to make these. I ordered the mandrel and some corian to start them out. I have been trying to explain to them what the mandrel will allow them to do and these are a couple of great examples. Not like actually getting the mandrel will do though. My daughter won't leave the shop as it is now. We made a few home made backer plates and she has been turning practice stuff for the last two days. I don't know what time she came in last night but she was in the shop until 11:00 the night before. and that was just to practice. once the Deluxe backer plate arrives I will never see her again.
