During my last project, I noticed that my carcase saw is not cutting quite as well as it used to, and that it can even occasionally bind in the kerf if I’m not careful. It still works pretty well after about three years since I first shaped and sharpened the teeth, though.
Independently, I decided to finally get a macro lens, and like the nerd that I am, I thought I would point it at the saw teeth to see what they look like (since these are too small for me to really want to strain my eyes on):
Remember that this is a 14TPI saw, so the area shown here is a little more than a half-inch wide. The image here translates to roughly 8x magnification on a 100dpi display. Here’s a view from an angle:
You can see that a few of the tips have gotten the slightest bit rounded. I will need to resharpen this soon, though I think I’ll take it through the next project first. It will be interesting to see how this looks when I do so, because this was basically only the second crosscut saw I ever sharpened, and I have a much finer file now.
I’m almost tempted to get a new plate and back from Mike Wenzloff, like I did for my recent joinery saw, because it would be heavier and thinner. But I don’t think I want to mess around with making new saws for now. I should at least put together that big backsaw whose parts are currently waiting for me. Oh, did I mention that I fell victim to the miter box syndrome? I’m not sure what to do about that, either.
