Re: "Jupiter 1" Cutting wheel

 

I would recommend making an indexable jig or make a mandrel to hold the cutter in a Spindex, mounted on the bed of a mill, set the proper angles for the sharping process, use a diamond wheel mounted in a mill to sharpen the part.? Some of those angles on the cutting wheel really look beat up. ?

Setting up the part for sharpening will require a bit of ingenuity.? There’s many ways to sharpen the blades.? If it were me I would just junk the thing and replace it with something brand new.

Have A Great Day??

My "Jupiter 1"? pencil sharpener?has a 45 mm wheel for cutting.
However, the cuttings are not very good now after many years in use.
So, I am asking you for advice on how to scarp the edge.
The scarp edge of the knife is being a little bit round.?

Look at the pictures,?
Shall I scarp side A or B ?






Ps. Thanks to all for advice on how to make the 2 missing screws.
