I'm getting up the nerve to turn some Eucalyptus burl cap.
I want to make into a natural edged bowl (hopefully nested set).
I've got a fair amount of experience using coring chisels on local stuff like cottonwood and maple.
I want to start out by coring the bowl blank out of the cap and then turning the remaining cap into a platter preserving as much as the outer edge of the cap as possible.
For my project I don't want to waste any by mounting it to a face plate leaving screw holes. So I need to use a waste block glued to the flat bottom of the cap. The question is what glue? Should I use a large thick piece of say maple and mount it to a face plate or a smaller piece that can be held in a chuck?
So far I've had a couple suggestions of using CA glue (even though the burl is several years old it is still wet) and using titebond. One suggestion was use titebond with paper between the waste block and the burl. The paper would permit me to separate the waste block from the burl more easily but I worry about the stresses during coring.
