Valve pocket/bowl hog tools....

Brian can you explain what you mean by "make your own" ?
I have an old B&D in great shape and make my own stones out of blanks.
I have knockoff dremel tool, but attachments are friggin pricy. I've checked walmart and limited supply there. Suggestions?
The very reason I like a Dremel. It doesn't gouge all at once like a air grinder
Heres some of what I'm using
