old skate sharpner

[egmorin 0]

I just purchased an old skate sharpener. I should have done this years ago. Hope you can see the pics. Anyone recognize this make or model? I cant seem to lower the diamond arm to shape the disk correctly. The diamond seems to have only one range of motion and the disk is too high to center the diamond on the disks edge. The diamond in the picture is at its most level to the ground. As you can see, its at the bottom edge of the disk vs mid disk. Any insight to using and setting this thing would be appreciated.

Please view pics here as I cant seem to add them to the "insert image URL", sorry.

Hey Moderator, How do I insert a personal image....vs one from the net before posting? I have a couple pics, but not with a URL...

You can use one of the many image hosting services. imgur is a good one. Image uploads are only available for Members++ which are available here: https://modsquadhockey.com/forums/store/category/1-subscription-to-gear-exchange/

I haven't seen this one before or know who made it. Over time there are literally hundreds of different models of skate sharpeners that were made. Can you shim the bracket and raise the arm that way?

Edit - looking at the pics again, don't know if this is an issue of camera angle but the diamond arm doesn't look level. It looks like it slopes downwards towards the stone and hence this pushes the point of the diamond downwards. If this is the case can you level the arm by bending it?

2nd edit - raising the arm by shimming the bracket may not work that well because of how the wheel is connected to the bracket to move the diamond in and away from the stone. It depends on how much flex you have there and if it can raise, does it change the geometry of the arc.

Edit 3 - lol, have to stop doing edits. The primary concern is not where the diamond point is positioned, what you have to get right is the pivot point of the arm, this controls the arc of the diamond point. The pivot point of the arm needs to be centered on the middle of the stone (I can't tell from the photos) and the diamond tip needs to be in line with the center of the pivot point. Get this right and it will be centered to the stone and the arc will be correct

I would disagree with your one commenter, the big silver wheel should move the diamond in and out (closer to or further from) the grinding wheel horizontally.

Edit all you want if it helps me 🙂 . It almost looks like its missing 2 diamond shaped spacers/shims under the backside of the arm where the arm apparatus slides left and right...above the spring bolt. You may be correct in saying the diamond arm looks bent...but its cast iron and totally solid. It would have to take a lot of torque to bend that.  Pivoting the arm moves smoothly...its just not centered on the edge of the disk.  Here is the ONLY footage I've found on line to date and hence why it may be a "fleming gray" older make:  https://www.youtube.com/watch?v=IbAG2hXbu18 It doesn't look too old in the video and has the same action as mine.  Would be nice to get this thing working 😞

You are correct. It does just that and works well....just the diamond arc is not centered on the side of the disk....and I cant figure out how to get it adjusted right.
