Does anyone have advice on gluing purpleheart, also known as violetwood? We have tried Excel One polyurethane with little success and suspect a lack of pressure or a burnished joint was the main cause of the failure to glue this very hard and dense timber, however all the information on this species say it is easy to glue.
From contributor C:
I too have had trouble with this problem. I have had success edge gluing panels with yellow glue without mishap, maybe due to the floating nature of a raised panel. But when I glued up mitered cases for jewelry boxes with epoxy and also tried yellow glue, they practically fell apart. It seemed that any exposed end grain cells secreted oil or something to compromise the adhesion. I opted for cross doweled corners with hard maple Miller dowels.
