Quote from: Query on February 02, 2025, 01:00:39 PMThe only thing this has to do skating is that a lot of skating equipment is produced in the U.S. or Canada. E.g., I will likely buy Jackson Skates, made in Canada. Tariffs could make them more expensive.

Jackson is a Canadian company, but most of their boots are not made in Canada.  Even the Supreme 5362, one of their highest-end stock boots, that I bought late 2022 was marked "Made in China".  My previous pair of Jackson Elites, purchased late 2014, had no country of origin marked on them. Like many companies, they use a variety of contract manufacturers from all over.  I've never bought Ultima blades, so I have no idea where they are made.

I don't know how tariffs will be applied with today's complicated global corporations and global supply chains.  We shall see.

says U.S. president Trump is imposing tariffs (taxes) on imported Canadian and Mexican goods, and some other countries. And Trudeau says Canada will impose tariffs on imported U.S. goods, urges Canadians to "Buy Canadian". Other countries may impose tariffs on U.S. goods too.

Does anyone know if it affects Alaskans who order goods shipped via truck from the U.S. through Canada?

Edit: A few U.S. states import hydro-electric power from Canada. If that raised the price of electricity in those states, it could impact some skating rinks.

Gold Seal revolution is the much more trickier case. This blade designer only target must have been to make them visually pretty. Only flat area is in the behind the toe picks. Here is one method what JW recommends. https://www.youtube.com/watch?v=69tWd_K5iBI

I have tried it and I didn't feel it reliable. When square was indicating edges to be even (in the back) magnetic BAT gauge did indicate that edges are heavily uneven. I would recommend using similar BAT gauge than what Paramount introduces in their video. https://www.youtube.com/watch?v=JjVpbt8ePmc&t=334s

Note that in Gold Seal revolutions it might not be smart to use skate holder which has wide contact area. Concave blade and flat counter face if not good combination. Hockey skate holder with narrow contact areas is much better for them.

Its nice to see new active guy here in the forum.

I was also happy to hear that you double check edges evenness after the sharpening (directly from the blade). Even your squareness check in the skate holder would include some deviations, you will notice it later. Only problem is that you might need to grind skates several times before edges are perfectly level.

What comes to the scratches and other damages on the aluminum chassis, doesn't them exist also when you remove skate from the holder? Or is the trick that you use stanchions when skate in not in the skate holder?

I would recommend to use same type in square than what I use. "The magic" in my square is knife edge. It does not create shadows like your, which ruler part is probably ~1mm thick. Thinner the contact area is, easier to see the light leak. You can demonstrate by putting you square rules flat part against the blade stanchion. See how much you see light leak. After this start to tilting you ruler until only the ruler edge contacts (45 degrees). My assumption is that first stanchion looks 100% straight but, when only the corner contacts you start to see some light leak. This is the reason why knife edge rulers are used in the quality controls.

In the normal Gold Seals I use stanchions to verify edges evenness. In the beginning the problem was that stanchions were covered by skate holder which did mean that I need to take skate out from the skate holder to be able to measure edges evenness. When you put skate back to holder, it will never position similarly as last time. Try to check this with your machine with any blade. After you have finished the blade, remove it from the holder and paint the blade with marker. Put it back and make one grinding pass. If all marker traces are gone and edges are still even, you was a lucky one. Tip of the day...try to find some way to be able to use stanchions for measurement even skate would be in the skate holder.

How to put them on the holder correctly?
measure edges like regular gold seal's?

Kaitsu thank you very much for your reply
Yes ,You are right that we do not know how well the ruler end is made to be square.

but I think it's not a bad method at all am I right ?
 3beltwesty in his video says that mk phantom blades, I think also Gold seal in the place where we put them on the holder are parallel so assuming they sit well on it, we can check like that. of course after removing from the holder I check again.

I often have very damaged matrixes with many scratches on the chassis, then there is a problem with checking as you show but I agree that method You showed is the best .

I would not use this method, at least on Matrix blades. On Matrix, same square could be used like in normal blades. https://youtu.be/DbrR3hBtm70?si=yrajM4-v2Kt6Jw8I

On side honed blades this methods is much better than nothing or just eye balling without any tools. Gold Seals are a bit tricky and Gold Seal revolutions real nightmare.

Some skate techs uses magnetic bat gauge, that part which lays against the edges. They use skate holder as a datum and they eye ball if bat gauge and skate holder are parallel.

Using square like this has couple things which causes high meauring uncertainly.
1. We do not know how well the ruler end is made to be square
2. Blade is just <4mm thick. Its not so easy estimate edges unevenness from so short distace.
3. Skate holer is your datum, I dont think blade will never sit 100% perfectly in the skate holder.     

Guys,
 is this method of measuring edges are good?
 Especially for matrix or Gold Seal

Oui,
Je te promets de faire d'autres vidéos, sur youtube donc.
