You could try swapping rings every 1 or 2 sharpenings, either to a diffierent radius or another ring of the same radius. That would give it a chance to cool.

I noticed recently my fan no longer runs when I start a sharpening. Has anyone replaced their fan? I haven't check yet how easy it is to access it.

You have at least 3 months to figure out your ROH. I would go to a shop and request what you think you have and then try it out (probably 5/8 or 1/2 if you just get a standard or regular hollow without specifying). As far as price, there was the initial kickstarter price, then a pre-order price, then another increase in price. The current price is what is on their website. I got in on the early pre-order price and hope to see it in about about 3-4 months.
