Sparx Skate Sharpener - At home sharpener

No idea what setting they used. They said they followed the in box instructions. Dows it really matter? 

 

And what do you mean if that actually happened?? It happened!!! 

It matters because there's only one "setting" that determines contact with the steel, and that's grinding ring height. Even if the user got this totally wrong, it still wouldn't alter the profile.

It would be a disservice to anyone looking into a Sparx if they thought their child was going to suffer an injury based on what appears to be an anecdotal corner case.

I'm still confused as to what "setting" they used to ruin a profile, assuming that's what actually happened. 

Nobody is arguing that Sparx is "perfect'. That's a straw man argument. However, it does presume the owner can follow simple instructions. I found them to be incredibly simple and other owners I've talked to have had similar experiences. 

You could ruin the profile if the grinding ring engages the steel too early as its then removing material from areas that should not be sharpened.

Howdy,

Hard to see how that would pitch the blade back 2/32 or whatever it was.

I don’t see how that would ruin the profile, you just get a bit of metal ground away from an area you don’t skate on. But if someone really is so stupid that they can’t set the height, it probably is best for all concerned that their blades are trashed and they are kept off the ice and out of harms way.

Incidentally, young children probably shouldn’t use the Sparx, but I’m sure a 13 year old would be fine as long as mum and/or dad showed them how to use it first.

I'll make sure to tell the parents that. Thanks.

That reads like sarcasm. Not sure why it was needed.

In all honesty, what you could do is see if they can recall what specifically went wrong during the sharpening process (the next time you see them).

Has anyone else had a problem where the toe and heel of the steel are not in alignment?  I finally got an edge checker.  What I'm finding is that the toe and heel are not equal, as if the carraige isn't running straight along the blade.  No matter how much I adjust the knob, the relation stays the same between them.  The right edge of the toe was high, but the heel was level.  When I adjusted the knob to make the toe level, the left edge of the heel was high.  It was the same issue, off by the same amount on 3 sets of steel I tried (just to make sure it wasn't the runner being bent) leading me to assume it's the Sparx itself.  It could absolutely be user error with either the machine or edge checker.  But when the results are replicable and consistent every time, that is probably unlikely.  Anyone else experience this?

There are two scenarios that I can think of, one you have covered (bent blade) the other is that the steel is not true and giving a bad reading on the edge checker. What type of steel are you sharpening?

Three different kinds, with three different characteristics, in three different holders.  One is Flare regular steel that is in my player skates.  One is Massive Blade DLC in my goalie skates.  And one is a set of Tydan regulars that I sharpened in the Sparx blade holder.  All three showed the same results.

I cant speak to the Flare or Massive Steel but I did have the same problem with the Tydan steel. It was very frustrating and I ended up switching to Black Steel Step Steel which is way superior to the Tydan Steel.

Hmm..

Did you sharpen all three outside of the holder? 

Idk about coated steel, but this is what Sparx has to say,

Does your blade have a Black or Chrome coating? Or Is it made from multiple materials (Bauer® Fusion, CCM® Rocket Runner, etc.)? These blades have inconsistencies in their sidewall structure and we have found it difficult to get a proper edge height reading on them.

Did you try this?

Also, item #2 here is interesting and I think relevant.

Does this happen in the skste? And always in the same right or left skste?? 

If it happens in the same skate every time holder is bent. 

If your doing blade only out of skate.  The machine is the issue.

Thanks for the input, especially that last blog post.

I went back and tried to remove as many variables as possible.  I got the alignment ring back out and did that.  I pulled out an old Step regular goalie runner - since we agree Step quality is probably the best - and sharpened it in the Sparx holder.  And I ran 4 passes, per Sparx's recommendation, to adjust the edges.  I tested in 3 places along the blade and it was all nearly perfect, maybe out by one click either way.  So knowing that the machine was set to produce level edges, I took my Flare steel off the skate and sharpened it.  Testing it out of the skate again produced pretty good edges, with a little more deviation.  Lastly, I ran the other Flare runner in the skate, and tested it there.  The results were all over the place.  So it clearly seems that the problem was either with the sidewalls of the steel or the checker, or a combination of both.  The Sparx is fine.  The Flare Square is different than most others because it has a deeper channel and the top corner where the edge sits isn't square.  I think the design was what was throwing it off because the Flare steel is worn down and may not have enough left to make good contact with the edge checker inside the skate.  Either the set screw lands on the flared part, or the whole thing hits the holder.

What OTG28 said...  you'd be surprised how many holders on skates have slight deformities.  

Thanks, guys.  It was happening on three different sets of steel, both sides, two in two different holders, one not in a holder.  So while I completely agree Holders can be bent or not aligned properly, that didn't seem to be the case here.  It was more likely a combination of the way the Flare Square works and is designed and inconsistent sidewalls on all the steel

That will definitely cause an issue. 

Its actually pretty simple no matter what machine you use. 

Eliminate the easiest problems first. 

So in the end itvwas only the Flare steel that was off??

All of them were the same, which was based on the calibration of the machine.  I don't think any were off, but just the square was giving me a false reading because of the design.  The Flare Square works on regular steel too, so I was using it on all 3 sets.  Out of the holders, the readings were all consistent and pretty level, especially once I recalibrated the machine.

All magnetic checkers are inaccurate. They are not consistent or precise. One should never set up their machine using one of these.

It's not really setting up the machine.  I used the calibration tools for that.  It's like using a square to check for level of edges so you can make fine tuning adjustments to the jig if needed.  Even with the tool, the carriage can still be off a little bit.  So the square is more to make sure something isn't horribly incorrect.

I compared gauges from ProSharp, a Canadian ebay seller, Sparx and blademaster. The latter three all agreed with each other very closely when used on the same blades. The first was out by a few thou. What is the source of your information? The Sparx optical aligner can get you close enough, but not bang on.
