Spectator Skating Discussions / LiveBarn video privacy and safety issues
« Last post by Query on February 16, 2024, 07:18:37 PM »
LiveBarn has video cameras and microphones at ice rinks, pools, basketball courts, playing fields, etc. - mostly in the U.S. and Canada. AFAICT from promotional videos, the resolution is 4K. I don't know if you can identify faces.

People who subscribe can watch games and practice sessions. The cameras are on all or most of the time, except during sports blackouts by leagues like NHL. (You can see some NHL practice sessions.) To some extent you can even watch video on demand. LiveBarn installs the video cameras for free, and pays the facilities a portion of subscriber fees.

In most of the U.S., videos are legal in public facilities, and help deter crime. Not sure about microphones. But these could also be used by stalkers, thieves, as well as people seeking to learn sports opponents' skills, weaknesses, strategies, skating programs, etc. I don't know whether skaters & coaches wishing to black out their private practice can negotiate for that.

Does any of this bother you folks?

Excellent!

That's a very clever sandpaper holder for the abrasive "stone". Great job!

Today I was struggling a bit with my 3D printer, but I managed still to make my own honing cylinder. Basically I can choose any grit. Same idea could basically used also in original Profiler if someone wants to have new honing cylinder and they cannot be found from the markets anymore....or if you want some special coarseness.

BTW, I'm not sure the Pro-Filer patents are still in force. How would one figure that out? 

By Googling...https://www.freepatentsonline.com/5431597.html

What I know, patent protection is granted for a limited period, generally 20 years from the filing date of the application.

Hi Query,

I hope you can get back on the ice often and have fun while you're there!

It's not so much a style thing, progressives are progressives and crossovers are crossovers.  If the coaches are teaching crossovers, then either they are emphasizing them for the efficiency in gaining speed for freeskating, or else they never did dance and/or learned progressives.

If you know progressives and want to do dance, that is a positive for finding a partner!

There's always figures you know :-)  They are kind of zen-like and a completely different and cool experience on the ice IMHO.

Just call the scratches an "extended chrome relief" feature.  ::>)

BTW, it IS possible to get uneven edges when using a ProFiler, but it's obvious that there's an upper limit on how much error there can be. The tool is mostly guided on the blade within a narrow range. Frankly, I could never detect the slightly uneven edges produced by a hasty ProFiler sharpening although it could be measured with the very sensitive tools I own.

If you can inexpensively produce a set of chassis, each with a separate gap value, that would avoid the complexity of a design with an adjustable gap.

Even if the material of the chassis is soft enough that the chassis itself does not scratch polished chrome (or stainless) surfaces, scratches will be inevitable (in the absence of tape or other protective coating on the polished surfaces).  As you perform the hand grinding, particles of abrasive or steel will come loose and fall in between the chassis and polished surfaces and cause scratches.

Thanx Bill. I was too unpatient and made first 3D model based on your old photos where you instruct using of Pro-Filer. This means that print dimensions are not as per as your excellent dimensional drawing. Print is also with 1/2" radius.

At the moment my target is to study how far this tool goes in to the chromed surfaces. In the other words, how big risk there is that chromed surfaces are scratched with tool which slot has same width with the blade. Means no any protective tape cannot be used. Another thing what I try to understand, how well this tool ensures edges evenness and does it round the edges like so many other tool what I have tried so far.

Even the adjustable slot would be nice, I dont think that I am able to tune this specific tool design so that it would work as well as without any adjustments. Its easier just to print bodies with different slot widths. Cost of one print is so low. During the weekend I might have time to draw Bergham sharpener. I have planned to print it also just from pure curios how it works. Can centering work so well that it could be really used. These all are just tests to feed my study hunger. Maybe this help also those whom does have Pro-filer and they would like to improve their tool.

There is also the Blade Barber:

https://www.bladebarber.ca/

They claim it can sharpen hockey and figure blades to 4 mm thick. I don’t see how it can get even edges without being tailored to a specific blade thickness. Presumably they allow for a certain tilt, maybe one thousandth of an inch. I did a quick calculation assuming a 0.5” hollow, and I think using this tool the edges could be out of kilter by 3 thousandth of an inch, which is unsatisfactory in my opinion.

Oh, you have True hockey skate boots, and you're talking about Scott Van Horne, correct?  He later adapted the tech for Aura figure skate boots.

Yup, Scott Van Horne. I hadn’t heard of Aura skates.
