Q&A with Michael Roper

capthharol18594 asked:
I have tried this project, and have problem. I completed thru drilling with forestner bit then tried to use 1/2 bowl gouge but my attempts did not produce a level end. What am I doing wrong.
Michael Roper answered:
Hello Cap, I'm sorry but I am not exactly sure what you mean by a level end. Are you having trouble fitting the vessel into the jam chuck or are you having trouble making the Jam chuck? If your having trouble fitting the vessel into the jam chuck it is usually because the cove cut going up the neck isn't steep enough. Hope this helps.
capthharol18594 asked:
What I am having trouble with is after drilling out interior. I am finishing off top of vessel. My top is roughly at 15 to 20 degrees slope it is not level or at 90 degrees to vessel like yours is. I have not created jam chuck yet as I am concerned that it would not fit or hold properly.
Michael Roper answered:
It sounds like you need to make a straighter entry cut on the edge. The top of my vessel is at about 20 degrees but the shoulder is what need to be at 90 degrees to the outside wall to get the vessel to sit flat in the jam chuck.
