...and I can't get a good clean cut. I am leaving a little point which sticks out into the bevel at the place where I start and end the cut...
Hi
Patty and welcome to the G.
This issue is part of the problem on any oval cutter that using a "trailing blade" design - where the blade follows slightly behind the leading edge of the tangent point. Carithers, C&H and older Starr-Springfield oval cutters all could display this issue.
Technique will help a bit -- lightly dragging the blade on the interior first and slowly pushing down on the handles to lower the blade into the mat board. A little bit of use of an Emery board following has been standard procedure for years.
The only machines known to track in exact position in creating ovals are the Gene Green Oval Cutter, Fletcher F-1000 and F-1100, and of course all CMC's.
Hope this information helps.
