I recieved a hapstone r2 for fathers day, haven't had much time to use it, but I noticed when I clamp a full flat ground blade... when I flip the blade my angle is off on the other side

Is there a certain order to tighten the screws on the clamps? ( I would tighten the ones closest to the blade first then the rear grub screws after)

Thank you

Great question to ask, and i am looking forward to the answers. When i look at these systems that is something i think of, because if they are not perfectly centered this will be an issue. Hope you get help and get it sorted. Would love to see your opinions and a brief review when you do get it sorted. :thumbsup:
 
cudgee cudgee I have a hapstone v7 and now the r2 can't wait to get more opinions on the clamps because the r2 is way more refined!

yoko yoko use the link that Old Biker posted and look at step B.

You want to loosen the small screws that are securing the flat springs to the jaws of the clamps and when you do this have a flat peace of metal in them and use your angle cube to set one side of the clamps jaw at zero then tighten both the small screws being sure not to move it up or down then flip the crossbar and repeat.

If your clamps go off-center only when you use spacer screws, and clamps are symmetrical without spacers, try to use spacers at a minimum. Unfortunately, spacers cannot be used to set the desired angle between jaws to have a large contact area for distal taper FFG. According to my research, your sequence is the best. Use one clamp for FFG area, don't put the blade too deep (2-3 mm is enough). You start with the spacer in zero position, tighten the main screw, use the spacer to amplify the force. Use the second clamp as support, for non-FFG area of the blade. If you don't have non-FFG area, please let me know the knife model.

The linked article will help only if your sharpener is always off center. It will not help with the spacer problem. There is no possible solution to use spacer at maximum.
Although the vast majority of FFG blades have non-FFG area for support clamp, we will launch alternative clamps for FFG soon: Hapstone wholemilled fillet/FFG clamps and KakBritva clamp series.
 
yoko yoko You can contact gritomatic and ask about the adaptors they have to use different clamp's with different systems,I think they have something that let's you use a TSProf clamp with a Hapstone sharpener that's the way I would go if you want to be able to calibrate the clamps.
