Notes & Comments![]() Another View of Filing Angles ![]() Triangular File Used vs. Saw TPI Image courtesy Tools for Working Wood Jointing: When jointing the tops of the teeth, a saw jointer makes this easier. However, you could also use one of the jigs in the recommended books below. Engler's and Lie-Nielson's books show this best. Setting:. When setting the teeth, a saw set is critical for this. If buying one, get one with a pistol-grip, and which accommodates 4-16 TPI. The saw set I use is a Stanley model 42W. It works much better than the models 42 or 432. I have not tried the Stanley model 42X, nor have I tried any of those newer ones available on eBay, so I cannot speak to their abilities. Only set the top 1/2 of the teeth. Increase Set for saws with coarse teeth. Decrease Set for saws with finer teeth. For very fine saws, the burr from the filing will probably give adequate set. Filing:. When filing the teeth, the saw must be held solidly along a straight edge. The goals are to
A saw vice like the Gramercy Tools 14" Saw Vise is very good for this, but it can also be made from wood (e.g., a 2x4). There are jigs in the recommended books below. Engler's and Lie-Nielson's books show the options best.
For the triangular file, use the specified size based on the saw's teeth per inch (TPI) as shown in the lower picture to the right. French veneer saws have a variable rake towards the center, and only have a bevel on one side. Best to have a professional re-sharpen these. Blackburn Tools' web page, Saw Tooth Geometry, has good visuals to explain Drop (which they call, Slope), Fleam, and Rake. |
