economical truing/shaping brake to square up my wheel?

Question

I recently bought a Boyar Schultz 6x12 Surface Grinder. I purchased a new Diamond grinding wheel 7"x 1.25" x 1/8" Type 1A1. While grinding a 2" diameter face I noticed that one location of the grind is always lower than the rest of the surface. This appears on the back edge on the last pass. I rotated my Vblock and piece 90* and had the same problem. I assume this is due to the fact that the wheel is not square and the wheel could be at a slight angle on the edge and not make contact.

Where can I find a economical truing/shaping brake to square up my wheel?

Pal   You can true up a diamond wheel by grinding a small soft steel block.   See the following url for options   There is a hard composite rod we had at one place I worked but I cannot remember the product name.  If I find out I will post it here later.  It was a 3/8" dia rod that was placed in a holder and the diamond wheel run across it in .010 passes very quickly.  Mainly used it to get rid of the taper on a dished diamond wheels on T&C grinder.Pal wrote:

I tried that technique.At 0.01 of a cut I was stalling out my single phase motor.I tried less of a cut and it worked a little better but not where I need ityet.Could I run my diamond blade over an old carbide wheel locked into thechuck?Or make some jig where It could spin?Or would the small diamond I have for dressing up carbide wheels work too?PAl

I got the name of the product I referred to.  Its made by Gidco-foulkes, see the url below sure of the price, more than a block of steel and cheaper than a brake controled truing device :-)Pal wrote:
