I've been through several sharpening systems. I became quite fond(and proficient) with the Edge Pro. But after being disabled & my left arm/hand being paralyzed, two hand sharpening was no longer an option. So I switched to the WorkSharp. And I became very proficient with it. But I always have preferred a stone finished Edge. And ever since the Shapton Glass stones have been available for the Edge Pro, I have been drooling over them. So I went to work. I had given my Edge Pro away, and certainly was not going to spend the money for a new one. Not when I knew I could build one to hold the blade, so I can use it with my one hand. And as most things, might as well go all out! So 6061 T6 aluminum billet became the main building material.

Here are the materials. 6061 billet bar, 3/8" 15-5 stainless rod, & 3/8" stop collars. The L shaped brackets started as 3/4"x 3/4"X 1" bars. I cut and shaped them them with my belt grinder. Then added 45 degree cuts to hold the backing plates of the stones, just as the polymer brackets on the Edge Pro.



From there it was just drilling, tapping the threads of the holes in the billet and threads on the stainless rod(that was tough! That 15-5 is incredibly strong! It is similar to stainless used in gun barrels and frames).
And the stop collars are used to set the angle.


Works fantastic! I love the Shaptons. Much more than the Choseras I used with the Edge Pro. For now I did a simple clamping system, but I'm working on using neodymium magnets to hold blades in place. This was a lot fun figuring out and building. It's not quite as cool as building the firearms or making the knives I do with one hand, but still pretty cool. And I spent less than $50 in materials to build it. Bit more on the stones, LOL. What you guys think?
 
That is awesome! Thank you for providing pictures and a bit of a walk through. Can you provide two more photos, please? I'd love to see a closer view of the pivot unit and then one of a knife in your rig ready to be sharpened.

Thanks again!
 
I'll add some better pics once I make the magnet hold. The pivot is 2 of those 3/4"x 3/4" x 1" billet bar stock pieces, with a 3/16" shoulder bolt & bronze washer between them creating a pivot. It's held between the 2 stop collars, so it can rotate 360 degrees.
