3 Profiling Skate Blades Profiling Skate Blades In this section you will learn: What a profile is How to profile a hockey blade How to profile a goalies skate About Dupliskate s practical guide for hockey blade profiling What is a Profile? Profiling is the shaping of the skate blade to suit the individual requirements of the skater. The larger the radius of the profile, the more the blade has contact with the ice. This results in more longitudinal stability. The shorter the radius of the profile, the less the blade has contact with the ice, allowing for an easier pivot action. Profiles are measured in terms of the length of the radius of a circle The height of the skater is the only factor which influences the choice of a profile. Tall skaters will require flatter (11 ft or 13 ft) profiles while short skaters will get the best skating results with more curved (6 ft or 7 ft) profiles. Example: 6 tall (1.80m) we would recommend 11 ft. profile 4.7 tall (1.40m) we would recommend 7 ft. profile To Profile a Hockey Blade 1. Measure length of hockey blade, find center point 2. a) place in clamp, center of the hockey blade at center point of clamp b) With plastic skate holder, push skate upwards so that it touches underside of clamp along its whole length making it absolutely parallel to the Dupliskate manual or electronic skate sharpener P a g e 2

If you are rockering, position template with center line opposite the appropriate position on scale to be found on right hand clamp 5. Tighten clamp ensuring template is parallel to Dupliskate machine by touching all 3 dowel pins of clamp 6. Bring grinding wheel to centre of blade (by use of the manual controls (8 or 9*)) positioning it at the pivot point of the template 7. Lower the guide wheel to the template until such time as the grinding wheel is only touching the skate 8. a) Program both forward and reverse speed controls at 9 b) Program automatic pass control to the number of passes you think will be required to achieve the required shape c) Push 8* automatic auto pass At this point, the Dupliskate skate sharpener works like key making machine copying the shape of the template. When both skate blades have been satisfactorily shaped: 1. Reduce speed to regular sharpening speed 2. Dress stone for the appropriate hollow grind 3. Give skates regular sharpening and polishing passes To Profile Goalie Skates Goalie skates should be completely straight with no radius. Therefore use a Figure Skate Bar as a template.

6 Balancing Skate Blades Balancing Skate Blades In this section you will learn: How to verify that there Is no high edge after sharpening skates with Dupliskate s manual and electronic skate sharpening machines How to Verify That There is no High Edge after Sharpening Skates It is possible to get a high edge after a skate sharpening. This would be because of a variation of the width of the blade and be corrected by the appropriate adjustment of the High Edge Control. Using a figure skate bar, see if the skate blade is balanced after the skate sharpening: The Diamond Dresser P a g e 5

7 The Diamond Dresser In this section you will learn: How to adjust and position the diamond dresser How to Adjust and Position the Diamond Dresser Here are a few points to consider when adjusting and positioning the diamond dresser: Different hollow grinds are achieved by dressing the wheel. Specific hollow grinds are the result of specific positions of the diamond dresser in the arm, as per the chart supplied on each Dupliskate skate sharpener. Line readings are taken from the BACK of the diamond dresser arm. Hollow grind is measured per line at the BACK of diamond arm. Dressing a Grinding Wheel P a g e 6

8 Dressing a Grinding Wheel In this section you will learn: How to dress a grinding wheel How to Dress a Grinding Wheel To dress the grinding wheel, follow the steps below: 1. Proper Dressing of the Grinding Wheel is the most important and delicate part of skate sharpening. a) Bring the Diamond to the right position in the Diamond arm b) Bring the Diamond Arm back until the tip is behind the stone c) With the Diamond tip at the center of the stone, move the Diamond Arm slowly forward until the Diamond just lightly touches the stone. 2. If the Hollow Grind is to be changed, dress the stone by rapidly (approximately 1 second) moving the dresser across it. a) In order to give the stone its correct convex shape b) To clean off its grinding surface 3. Dress the stone, taking 5 seconds to go across, in order to polish the grinding surface. The Diamond: a. keeps the stone surface very round b. Eliminates all particles of metal dust c. Makes available required Hollow Grind. P a g e 7

10 Suggested Hollow Grinds Suggested Hollow Grinds In this section you will learn: Dupliskate s suggested hollow grinds for sharpening hockey skates Dupliskate s suggested hollow grinds for sharpening figure skates Suggested Hollow Grinds for Sharpening Hockey Skates When recommending a hollow grind, we must consider opposing qualities. The deeper a hollow, the more manoeuverability is offered. However, a deeper hollow grind sinks into the ice more and therefore requires more strength and skill and is slower. A shallower hollow makes for easier and faster skating but less sharp turns. We therefore consider three factors for our choice of hollow grind: 1. Weight of the player (lbs or kgs) 2. Skating ability and technique (pro, very good, good, beginner) 3. Position played (goalie, forward, defence) Dupliskate suggests the following hollow grinds for sharpening hockey skates: P a g e 9
