The Pro Shop / Re: Pro-Filer Redirects to Wissota
« Last post by Kaitsu on March 10, 2024, 03:07:37 AM »I know that my friction test is far from the perfect. Example plastic piece I used does not contact the edges which are used in the skating. However I didn't have any other ideas how to witness visually the friction reduction with the existing pieces what I had on my hands in that moment. I repeated my non polished / polished test couple times by re-grinding the blade and re-polishing it. This is not shown in the video.
Paramount skate’s runners side surfaces are presenting me the dream side surfaces. They are plain grind to be flat without any bevel edges, which exists on most of the blades where chrome is removed. I truly hate when side surfaces are beveled / rounded already at the factory. Wilson might be the worst advanced blade manufacturer in this perspective. As I hate this feature so much, I am not going to shape side surfaces with burnishing tool to look like what I criticize.
However, I have lots of experience where skater says that skates are terrible to skate, even they have been recently sharpened (somewhere else). They feel too sharp. When I look the blades, I can feel that they feel extremely sharp when I test them with finger. ROH can be same as I would do, so root cause is not too small ROH. When I have reground the blades, they are happy. In my theory, there are two possible root causes which explains this. In some reason if you use coarse grinding wheel, edges feel sharper than with fine wheel. This is opposite what I could imagine in the first hand. This can explain also why profiler sharpening might feel sharper that what I have experienced with my printed tool. I don't think the printed cylinder is the problem causer in my tests, but I might to clarify this later by machining cylinder from the metal.
Another very plausible root cause for too sharp edges is that skate tech tilts honing stone too much in the deburring phase and/or uses too much force, causing burnishing (deforming) affect. Personally I have always been against the edges deforming. This is just my personal opinion, but I encourage everyone to sketch it to paper what does it mean when side surface is beveled / rounded. Note in your sketch that you are not skating in the way that blade would be in 90 degrees angle to the ice. Edge beveling / rounding issues materializes when you tilt the blade. I might be also wrong in this matter. Maybe this beveled / rounded edge is the "secret" why people like so much from the Wilson blades.
