[QUOTE="OmegaBunny, post: 7901368, member: 581050"] To figure out your kerf size you need to know how far on each side you want to go, say 6 inches on the front and 6 inches down the port... So the 6 inches would be the radius of a 12 in diameter circle Take the diameter (12) and multiply it by pi (3.14) and divide it by 4, since you are only doing a 90 degree bend. (12*3.14)/4= 9.42" or about 9 7/16" Then measure from the corner of the port 6" in one direction to get the end of the port. From that mark measure out the the actual Kerf length in this case the 9 7/16" whichever way you need the kerf to go. ***EDIT*** to figure out what the .42 equals start take your measuring tape and divide the numerator/denominator... 1/8" = 0.125 2/8" = 0.25 3/8" = 0.375 4/8" = 0.5 5/8" = 0.625 6/8" = 0.75 7/8" = 0.875 1/16"= 0.0625 2/16" (1/8")= 0.125 3/16"= 0.1875 4/16 (1/4") = 0.25 5/16"= 0.3125 6/16" (3/8") = 0.375 7/16" = 0.4375 8/16" (1/2") = 0.5 9/16" = 0.5625 10/16 (5/8") = 0.0625 11/16" = 0.6875 12/16" (3/4") = 0.75 13/16" = 0.8125 14/16" (7/8") = 0.875 15/16" = 0.9375 [/QUOTE]
