Skate rail grinding question

I have my "skake" rail grinder set up and am trying to bevel some 3/16" x1.5" cold rolled steel. It worked fine on one side but when I flipped it over to do the other edge, the grindewr wheel appears to have "glazed" and isn't cutting any more. Should I be using a more coarse wheel? Here is my setup... https://scontent-b-atl.xx.fbcdn.net/...24563162_n.jpg

I am using a Dewalt 3402 grind wheel. Dewalt https://www.google.com/search?q=dt34...m=122&ie=UTF-8

The good cutting disks are by Pferd - ask them for the thin Inox (Stainless Steel) disks.
Also, I can see where lowering the front edge will help. Will try this tomorrow. Thanks!!

Sanding disk, then "tip-the-skate" to prevent glazing.

About all I see here are "flap disks", is this what you mean?

I am at the same stage myself of being ready to cut/bevel my rails. Unfortunately I can't seem to find what I need. If someone could point out something on amazon.com, that would be perfect. Both for the cutter and the grinder/sandpaper disk.

Just use sandpaper made for grinder sized disks. 4" diameter paper with a center hole should be in the hardware store. here's an example http://www.screwfix.com/p/alox-fibre...ck-of-10/41299

Put the sandpaper on top of a grinding disk to support it. Do light passes with heavy grit sandpaper to take off bulk of steel, then go through progressively milder grits.

Flap disks have a bevel of their own that may make it difficult to figure the correct angle. I use flap disks for cleaning up steel and sometimes cleaning up welds.

Ok,
I bought a cheap $2.99 disc backer from Harbor Freight and a pack of their 36grit, resin coated 4 1/2" sanding disks. The unit chucked right onto my dewalt grinder pretty as you please and I have already beveled 72' of rail (144' of bevel) and am still using the first sanding disk. It's alot better quality than I expected for sure. I have 24' of v groove to go then I'll switch back to a grinding disk and hone them a little more. I already have the drill press tuned and ready to drill the mounting holes. Thanks for the tip guys!
