Here's a clip from a Dave Tutelman Shoptalk post on December 05, 2003 describing how he widened some narrow grooves:
"The maximum groove width allowed by the rules is .035".
The wedge as shipped had a groove width about .015" -- way smaller than allowed. So I wanted to widen them.
I have a Dremel tool. The abrasive metal-cutting disks for this gadget are .027" thick. So I ran the tool along the grooves. Clamped the head with the face up and accessible. I freehanded it; the original grooves provided a good guide for the blade. I cut until the disk settled down to the bottom of the groove.
This gave me a U-groove .030" wide, just about right.
Hope this is clear.
