I studied for a while video paul made abut recutting new teeth on an old saw and it was very very interesting. One among the best videos i have ever seen. Now what’is the difference between teeth re-shaping and final sharpening? Paul talked about this difference oin orde to make a “top notch saw”, while the saw itself was cutting straight.
In other words , if teeth are correctly shaped and set, what i have to do to sharpen them?
Carlop, Paul has at least one other video on sharpening a saw and it may help. If your saw is shaped and set properly, all you should need to do is sharpen it with a stroke or two on each tooth using a saw file. Be careful that you have the file at the proper angle. A small jig can really help with this. I use a 1″ x 3″ x 3/4″ thick piece of pine with a line drawn across one edge showing the “rake” angle that the file should be at when filing. If the saw file is inserted into a hole (for a tight fit) in the center of that edge and with one face of the file parallel with the rake angle line, then the block of wood can be held level when sharpening and it is much easier to keep the proper angle. A quick search for saw sharpening should find you some pictures of such a jig.
After the filing, Paul uses a small diamond hone (tongue depressor sized paddle with a small diamond plate on one end) to hone a secondary angle on each tooth to give it strength. Hope this helps.
