anyone that saw my display on darters may have noted the step drill that I use.. I know I pointed it out to several people.. the bottom/assembled darter had the belly grommet in place...I'll check anbd see if I have a pic. on my PC here...I have the pictures from the display on my home PC..

it's an older picture, but you can see how it works.. i bought mine from Mcmaster Carr... i also have one one of the machinists here made...I have two sizes.. both fit perfectly... I'd have to research the diameters, as, with most things these days.. I've forgotten...
