I used up all my FD corian #3 blades and am looking for replacements. Today the first batch of test blades came in. One dozen each FD Polar skip #1, #3; Pegas Skip tooth #1, #3.
I am cutting the interior of my heart boxes, 1 1/4 inch thick oak, some fairly sharp corners, same pattern for each blade, two boxes per blade type.
FD-P #3 first up, fairly good cutting very smooth finish, drop out slides back and forth in the hole without binding, good tracking (didn't wander off the line)
PST-3 good cutting, not as smooth finsh, one drop out would not slide all the way through, poor tracking.
PST-1okay cutting, broke one blade an inch into the cut, finished the first and second box with the second blade,not as smooth a finish as FD, drop out slides back and forth , poor tracking.
FD-P #1 great cutting, smooth finish, drop out slides back and forth, good tracking. I think this is the winner, especially for the sliding dovetails.
I'll continue to contrast and compare these blade to one another as I make more boxes.
