Hello knowledgeable folks. I'm looking to build a motorized truing/shaping device for the air spindle on my cutter grinder to modify diamond and cbn resin wheels. Picture a drive on the handle end with a shaft going through the spindle connecting to a bearing/spindle unit with the outside dimensions of a 5c collet. I must be blind because I can't seem to find a silicon carbide wheel small enough. 2"-3" od. 1/4"-1/2" wide with any size bore. Can anyone please point me in the right direction ? Thanks in advance for your help with this, Keith.
