Have to cut some knives down for one jointer. Took one of the originals 20" and set this up. Second photo are the new knives. T1 18 Percent Tungsten and 24" long. I dont see doing this on my metal cutting bandsaw and have not cut jointer knives down before.
I have the cold cut off saw which I had to buy to make a stair case as it would not fit on my metal cutting bandsaw. In looking on the net seems most people run cold cut saws with carbide blades but they were cutting different steel than these knives. May or may not matter. New knives are 1.125 thick approx and 1 1/4" wide.
I have a fibre wheel and it will wear. The knife could be standing up but figure down is better as it will wear less of the side of the fibre wheel. As the bottom wears away then it will expose a fresh side surface.
Ill do a test cut on an old knife first. Am I on track to cut this way? Will I need cooling? figured cut a bit then use compressed air to cool. I think I have tons of non ferrous blades but not any ferrous but will check. Warps my mind seeing people cutting steel with carbide saw blades. Just used to the tool and die maker and car builders and all of them had metal cutting bandsaws.
Do you need to weigh the knives after and if so to what resolution? I have a kitchen scale and it goes down to a gram but not tenths. Sure i read in the past picky shaper guys balance to a tenth of a gram.
Old knife for set up , New knife to be cut
