Just for information.
A diamond file will cut the hardened metal and it will also cut Carbide.

Well I've spent the last 5 hours or so stooped over the blade cutting new teeth! (Wish it was as easy to make new teeth for myself!!  ). 8 teeth per inch on a 26" long blade........you do the maths!  . Leveled the teeth, then trimmed then before setting the teeth. Hopefully I'll get the final sharpening done tomorrow, the tough bit, with the angles and all  |
It's a little late, but some good advice from Mike Wenzloff when cutting new teeth is to use a larger, coarser file for the early stages.
Makes the job go a little faster, and saves some wear on yourgood sharpening files.
Also too late... a saw with no teeth is at a VERY good stage for any blade cleaning or polishing you had in mind - the tooth (especially if they have significant set) make cleaning the edge very fiddly.

How did you mark out the teeth for cutting?

| bugbear I measured it out off an inch ruler, using ever eight to mark the point of each tooth (8tpi). I just put a little tick then on the flat of the fresh cut. Then filed in between everyone of these points until the new V cut reached the tick on either side. Holding the file at approx the same angle it took between 20-24 strokes to cut each tooth. |
