Krasch, glad we didn't scare you off! :)

Maybe I havn't made it clear enough that one needs to make very light cuts at the beginning, to establish a groove, before piling on the pressure. Under these conditions, I cannot understand why you...

Thanks Denis. From their catalogue, that is one of their "Premium" disks. Their Standard or Basic disks would probably not perform as well. Just mentioning this so that folk don't grab the first...

The Superior Bearing wheel actually has a radiused notch in the root so that it will clear a sharp 90 degree rail without any flat area. (You can test your bearing wheel on a "sharp" piece of iron)....

The light hand sanding is perfect. We sometimes even drag a file across a rail that is roughly milled (draw filing). Strictly, this does change a dimension somewhere, but by such a tiny amount that...

You learnt a lot from us guinea pigs! I made the mistake of handing the saw and the rails (for 5 big tables) to one of my staff and told him to get on with it. At the end of the day he was wandering...

After grinding those rails, are there any tips you could pass on to the folk that are nervous about doing it?

I think you have the wrong grinding technique if your disk is that deep through the metal. . . . .

I presume that all grinders have 4 screws placed in a square. What it the thickest screw (surely not 6mm)?

Thanks Doug.

Well, unless someone has a common grinder at bigger than 1.82", the hole size is now firmed up at 1.85" (as per Sean's first prototype, of which he gave me a dxf file)

Would anyone want the hole in the skate cut slightly bigger for a non-Bosch grinder? We might be able to decide on a standard hole size before the next round of Joe's laser cuttings. A slightly...

For cutting down the height with the thin disk, it is critical to make some very light cuts without flexing the disk at the beginning. Once the starter groove is established, then you can pile on the...

The tilting of the skate can done left or right. You can either make the leading edge of the disk cut up or down. I would suggest that cutting down is the better option . . . . .to avoid the burr on...

What did you guys do to stop the skate at the ends of the rails? Did you weld on a temporary stopping block to hit against the skate?
