Replaced the first 303s after 10 years and thousands of cuts.
Sped blade rotation speed up for 303s as advised by manufacturer. Like 20% faster rotation than a continuos blade.
Running at slow feed speeds this blade cut a 400-800 grit finish for 10 years.
Ordered a new one from johnjsgems and got great tips and tech assistance in replacing it. Thank you John.
Welded up a spanner wrench. 1.875" stud spacing, two 5/16" X 1/2" long hex bolts with threads hand ground to fit in nut holes.
(note sump on right created by 1.5" X 1.5" angle iron laying on bottom full depth where all the mud gets shoveled)
Old blade may have more left in it but it started cutting crooked.
The cause probably due to the width of the diamonds varying around the circumference and varying left side/right side of blade.
No matter, blade cut perfect for 10 years heavy service.
Will align carriage parallel to blade before cutting. Increases life of smooth cutting ability of blade.
