You need clamps, CA adhesive (Cyanoacrylate (super glue)), scrap plexi glass wet sand paper belt/disc/drum sander or maybe a dremel, plastic polish, buffing wheel. *****UPDATE ON GLUEUP**** straight ...
I use a taper in my lather with a 1/2" mandrel. It works great with most buffing wheels. But use a white jewlers buffing compound until it shines like glass and points out EVERY SINGLE FLAW YOU MISSED while sanding. After that its time to finish polish it with some plastic polish, i used hut crystal coat. But after that it is all done and ready to make salad!
I doubt it will hold up in a dishwasher. And i dont now how long the edge will last but time will tell..
thanks for looking!
