I wanted it to 1) fit my small work bench / project table, 2) be inexpensive, 3) be easy to construct, 4) really work!
Step 1: Wooden Base Assembly
I cut the pieces to form a "T".
I cut the long piece to fit across my work table, so I could clamp the finished "T" top and bottom.
A board was placed across the top of the "T" pilot holes drilled, then screwed together.
Step 2: Metal Materials
I used small boltds and nuts to fasten the braces to the "L" steel.
The view from the back shows how this gives a "U" shaped profile if viewed from above.
I used clamps to hold the entire assembly to the table.
Step 3: Knife Placement, Use of the Rod
Next, I screwed my knife blank to a piece of wood, and placed this in the vise.
I used a 3/8" steel rod as the angle guide for the jig.
Place the rod in one of the jig holes and check for the desired grind angle.
Step 4: Placing and Using the File
By changing the placement of the rod in the hole, you can change the angle of the file "grind"
Step 5: Using the Jig 1
I laid out the coarse and medium files I would be using.
I also added numbers to the holes in the jig so I could keep track of where I was in the sharpening steps.
Step 6: Using the Jig 2
Someone asked if I taped the file to the rod. No, I found that placing a hand on each end of the file was fine.
In the next picture, I hope you can see what the file was able to take away. The edge remains untouched.
Step 7: Using the Jig 3
Then I switched to the medium file and repeated the steps above.
Next I switched to a sandpaper -covered block.
Step 8: Finish
The blade was nicely reprofiled and ready for and sharpening for an even finer edge.
I could have also increased the grit and continued using the jig...
ALL THE BEST...
