X-Head Porting....

Thanks for the info guys... I havent touched the heads since last week... unfortunately I made a dumb mistake. I bought the other grinder from HF, but didn't pay to much attention and the grinder only goes up to 5/32in burrs, so my 1/4 burrs don't fit...

So I've been searching for an attachment to run my larger diameter shank burrs. Other options would be take it back and get a dremel that I can make accept 1/4 shanks, or buy smaller diameter shank burrs.
