The aim of this project is to design and build a static-blade saw that replaces the rotating blade with a japanese handsaw blade which is very thin and removes little wood during the cut leaving a very thin ‘kerf’ (< 0.5mm). Japanese handsaws are well known to cut aggressively and unlike european saws they do so on the pull stroke. Also, the blades in japanese handsaws are designed to be easily removed from the handle. If this blade were fixed at a slight slope away from the initial workpiece position and securely held vertically in a clamping mechanism, the work piece could be slid over the blade giving a very fine and accurate cut – tests with such a blade held in a vice have proven this technique to be effective.
The completed design will need to include an adjustable guide to firmly position the workpiece relative to the blade as the wood is pushed over the blade, a blade clamping mechanism that facilitates fast change-over of blade, a rise and tilt mechanism to increase the depth of cut and to facilitate bevel cuts and a sturdy cabinet.
Progress keeps on going, i have now reached a point where a basic shape and features have been selected. based on these, a very first draft CAD was done.
Important changes with respect to the BCT jointmaker pro are:
-only one sliding bench
-hand clamps used to clamp structure onto table
