@ cole...but what if you want to back out that 1" router bit a bit because it better suits the finished look you are trying to achieve?...let's say to 7/8"...the whole mathematics thing is not usable...i found a grizzly piece that i think will be a nice add-on piece to the legacy and let you index to any cut you want...any repeat from 1 to 360...it will be here in my shop tomorrow and i will begin the not-to-difficult process to modify it to fit the legacy...see attachment...there are 15 degree indents built into the chuck(24 divisions)...the chuck is 3" in diameter...and it has a #2 morse taper...should be interesting if i can pull this off...thanks for the reply...joe
