I was debating on whether to post this prototype sharpening jig that I made at the request of a friend who works for an outfit called Bullet Tools here in Idaho. They needed a simple jig to sharpen blades that were from 13” to 24” long. The bevel on these blades are all 18 degrees with a 25 degree micro bevel. These blades are used in their laminate, foam, and insulation cutters. The criteria was that the jig had to be simple enough so that anyone in their shop could use it to sharpen blades during individual slow periods.
I made this out of scrap plywood but I did use hardwood for the trunnions. I used the quick change sanding disk system from the sharpening jig I made and posted on LJs several months ago. This is a rather crude jig but it put a razor sharp edge on a 13” dull sample blade they gave me to experiment with.
The bed of the jig is 5”x 18” and the slide is 5”x 27”. the slide can be flipped 180 degrees so that you can load both sides with blades if you wanted too. It will hold all three of my 6” joiner blades end to end and both of my 13” planer blades end to end. The slide handle was an after thought and I will probably change it but it worked for this concept demonstration to Bullet Tools. They are now in the process of designing their own prototype jig using some of these concepts.
Thanks for looking!!
