Sparx Skate Sharpener - At home sharpener

[Sparx Skate Sharpener - At home sharpener]

I did a couple of searches on this, but couldn't find anything on here. Apologies if it's already been discussed. 

When doing multiple pairs of skates (not even anything crazy, like 2-3 pairs), the heat presumably bonds the wheel to the arm of the machine making it impossible to get off without letting it cool for 5-10 minutes. That is an easy solution if there's time, but if it's before a game, sometimes we're running through 10+ pairs of skates with limited time. 

Has anyone else experienced this? Any solutions/thoughts would be much appreciated.

I got the Anti-Scratch....loving it so far

It is very comparable to Bauer...lines up similar to my Itech

It seems a lot taller than the straight cut that Bauer/Itech makes. Can you comment on that?
