There are no words. My heart goes out to everyone who lost a loved one.

It's just so sad. There are no words to express how awful this is.

I couldn't sleep well last night and decided to check out the internet in the wee hours my times zone and saw the news then early reports of the skaters. 
Then I really couldn't sleep pondering unpleasant things.

It's so incredibly sad.  It would be about any passengers in such a tragedy, but the connection of skating and knowing circumstances of such promising kids goals, talent and work to get there, there with their families and or coaches... just 

Then getting messages from some of my skating friends and coach that they personally knew some of them or that we both knew people who worked with them etc makes the world even smaller.

Comme j'avais mis au tout début, moi aussi je voulais faire avec le diamant de blademaster mais au final j'ai copié le porte diamant ez sharpening qui est plus adapté.( Cette pièce m'a coûté chère en heure de travail !)
Attention les rails de guidage que j'avais commandé sont pas si précis que cela, alors là aussi j'ai improvisé, jusqu'à éliminer le plus possible de vibrations.
Sur ma machine 3", j'ai du monter et démonter et modifier très très très souvent toutes les pièces pour arriver à faire les réglages les plus précis possible.

great, I'm waiting for the video.
I made this machine because the SP850 only allows you to use half a wheel.
but because I have SP850, I used the diamond arm and 4 of my skate holders.

and I think those rails you showed would be great. I could put the Blademster SH-6500 holder on them

C'est déjà bien d'avoir fait cette construction, mais j'ai déjà une blademaster .
Je voulais construire ma propre machine en 3" et j'approche la fin.
Cela fait 1 mois que je travaille dessus et beaucoup de nuit à réfléchir aussi!. Je viens d'affûter 4 paires de patins et le résultat est vraiment super.
Dès que je peux, j'enverrai un lien sur youtube quand j'aurais le temps de faire ça.

as I already wrote, I made a machine for 8"
it cost me about 500 euros

Quote from: Kaitsu on November 11, 2024, 11:20:50 AMYou have started your designing from linear guide rails, just like me. When I have started to think about how to make spindle cartridge where to mount wheel, things get complicated.

What do You think about using such a solution and mount wheel direct on the motor ?

Quote from: tstop4me on January 12, 2025, 10:28:10 AMI don't know anything about Romania, but I'm surprised to hear that about Germany.  I would have thought there would be a cultural backlash against such an unsatisfactory system.  But maybe figure skaters constitute too small a population.  Do you know whether hockey skaters also need to go mail order?

Community too small. Here in my town hockey have to mailmorder too. The next closest rink thag has hockey is 2.5 hours away. Not sure if there's a hockey shop there.

Ice sports are not that popular in France
(Outside rhe alps). Even rinks are generally far between, and many are closing between the climate change and finances.
