Hi All,
I had a recent opportunity to pick up a few knife handle blanks recently - they are 0.5” thick. I will be cutting them down soon on a bandsaw to try and get them down to a width more suited for straight razor scales. This brought up the question “What thickness should I aim for?” In my collection I have scales ranging from 1-5mm (0.04”-0.2”) - in general I prefer 3mm and thinner for horn, wood and plastic. For scales made to date I have tended towards <3mm for lighter blades (e.g. 5/8 hollows) and only gone thicker when I had thicker blanks and wanted mass (e.g. for a 7/8 wedge). But I do seem to lose flex over 3mm. I am curious what thickness other scale makers aim for.
Caveats:
1) For the purposes of this question I am assuming a uniform thickness other than filleting the edges. Of course a scale with a domed outwards facing surface will flex more than one that is uniform thickness.
2) And yeah, I know when I cut the wood some of the material will disappear into the bandsaw. In addition the surface I get will need sanding to remove the marks of the blade. But I’m still thinking that if I cut into 3mm (1/8”) slices the 3rd slice will be a bit too thick. But going to 4 slices will likely leave me <2mm.
PS I actually got the 3 pieces of wood with price tags, plus the pen blank for $15, which to me seemed like a pretty good price. Not sure if the pen blank can be made into scales, but no harm in trying!
