Lathe Tool Sharpening Jig



.250" Aluminum has been resurfaced to .003" and here you see the degree lines being milled in 5 degree increments.

 Lathe tool support guide on top - .500" x 2.375" x .250"

Jig slide guide on the bottom - .500" x 5.00" x .250"

All hardware used to assemble the jig is #4 - 40


The main plate 5.00" x 2.50" x .250"


The bottom threaded hole lines up with the series of holes in the main plate. I was concerned that the knurled knob may not be secure enough so these holes could be used for a locating pin to hold the angle perfectly in place while sharpening. 

To make the pin, I used a #8 machine screw and turn down the end to .125" diameter x .125" long. A few turns of the screw locks everything in place.

 

 


.I spray painted the surface before wet sanding but got a bit too anxious and when I started sanding, the paint came off. I'll try it again another day

The center hole in the guide is in case I decided that I wanted to clamp the lathe tool in place. I may thread this and make a clamping plate.


Here you can see how it slides along the store bought angle stand.

 

Come back later as I may have added the extra features noted in the previous frame.
