Weight bolt screwdriver slot

[ken ken quarter]

Anyone have a quick and easy way to cut(mill, grind) the screwdriver slot in a headless weight bolt using a Logan 11x36 with a milling stack on the crossfeed supporting either a Dremel or a PC router? I've tryed stub milling cutters and woodruff milling cuters but they take too many passes to get the slot deep enough. Maybe a saw on the arbor, if so what kind is safe at router speeds? Feedback please, Thanks.

I just hold the Dremel tool in my hand and put two of the thin, brown grinding wheels on the arbor and cut a groove in the top of the stud.

This is the job slitting saws were invented for. Just make sure the second thing you do is install some kind of industrial strength shield around the saw for when it decides to morph into shrapnel.

A thin cut off wheel .0625 or .080 and arbor . A milling vise to hold your bolt and move for the cut into the head ... very simple , precise , and repeatable ... A drill press would be easy or if you're handy , a mill .

machine out a stud holder that mounts to replace the tool holder.nothing to it but a chunk of steel with some holes in it.put a end mill in the chuck and use the cross feed for the slot.make one stud holder and you are good for life.

Thanks for the feedback... Using Dicks method (two brown grindstones) I abandoned the lathe milling attachment and mounted a Dremel vertically on the Aloris QC to move across the centerline of the allthread rod in the spindle chuck. Park the Dremel close to the chuck...bring up the tailstock and center drill, drill,and tap the rod. Back off the tailstock and center the stones in the Dremel. Turn on the Dremel, face off the rod. Lock the spindle.
Cut the slot to depth with several passes with the cross slide. Cut the allthread to your desired length and you have a finished weight bolt and a blank end sitting in the chuck ready to build additional weights untill you run out of rod. No new tooling or jigs needed just standard stuff on my 11 x 36 Logans. ie no new money! LOL
