This is a cry for help.
Using a faceplate I have just mounted a 24 by 2 inch disc on my Nova DVR lathe intending to make a shallow bowl or platter. It was ready for turning when I realised I did not know how to finish the base. The disc is of such a diameter that I have turned the headstock at 90 degrees to the lathe bed and will use the out rigger to support the tool rest. Of course the tail stock will not be available to support the work piece.
It seems to me that I have three options, but all have their disadvantages:
- To begin with I can turn and finish a mortise or a tennon for the base, hoping that the chuck does not damage it beyond my ability to touch it up afterwards by hand.
- I can make a large MDF disc and tape the finished work piece to it with the base exposed. Then gently smooth off the base. Using this method, I lost a bowl that broke the tape and took flight only to crash and smash on the floor.
- I can use a thick glue block and, if it is thick enough, avoid reversing the work piece. I would separate the glue block from the work piece at the end of the turning and finishing process, leaving a plain flat bottom. I think I would have to use a glued paper joint, but my limited experience with this method has not been very good. The joint seems not strong enough for largish pieces.
What would you do?
