I am in the process of creating my own Worksharp sharpener. I have carved wood in the past, and wanted to improve my sharpening system. Presently I am using low, med, high diamond stones.

In gathering the parts need for the DIY worksharp parts and in carving the Tormek jig SVG-38 was essential . I could purchase it, but my late dads voice kept bugging me ” ... have you tried it ”. So here I am venturing to the challenge of making my own SVG-38.

I started of by designing it on Sketchup 2017, and an image of which is posted below. The jig is not tested in real life but it is in the process.

1) Raw material _ I had popular in the available thickness available so that is what I used. Size 1-1/4”x 2-3/4”

2) I made my marking on the wood per the document.

3) Sequence is important—First I drilled the 1/2 hole , followed by 3 clearance hole so I can cut the inner triangle. This is then followed by cutting on the scroll saw. Only then I removed the inner piece on the band saw.

4) Then the rectangle sides were cut off on the bandsaw. At this point I have the body of the structure, and a little sanding to clean up the edges.

5) Next I drilled and tapped for the screw that will hold the gouge. The male knob i had was a 1/4”-20 , so I used the appropriate threading cutter.

6) At this point the unit is ready for use – applied a little sanding and killed all the sharp corners. One area that is worth noting is I had to round off with a round file where the 1/2” hole exits the sides of the triangle. Not doing this prohibited the full rotation of 180 degrees for the gouge.

7) Now I took my larges gouge and tried it on. Also note the instead of the 1/2” support I had a 3/8” dowel rod to show where it will ride during the process of grinding the heal of the gouge.

Hope this helps any other woodworker.

Very nicely done. If you will use this often, I might suggest putting in a threaded insert for the knob. Tapped threads in poplar probably won’t last a really long time :-) I’m fairly new to carving tools but I have a Worksharp and the toolbar attachment that uses the Tormek jigs so I’ll definitely be watching to see how this works for you!
